Despite abundant nutritions, krill is barely used for human consumption. The objective of this study was to investigate the nutritional component and amino acid composition of krill and further utilizes it for food resource. Proximate compositions of krill meal were consisted of crude protein 58.85%, ash 13.89%, crude fat 12.45%, carbohydrate 11.01% and moisture 3.80%. The amount of total amino acid was 54.74 g%, and the major amino acids were glutamic acid (7.71 g%), aspartic acid (6.20 g%), leucine (4.72 g%), lysine (4.41 g%), arginine (6.49 g%) and alanine (3.25 g%), respectively. Total essential amino acid content was 21.87%, and the major amino acids were leucine (4.72 g%), lysine (4.41 g%) and isoleucine (2.90 g%), respectively. Content of total free amino acid in krill meal was 20224.30 mg/kg, and the major free amino acids were taurine (4501 mg/kg), arginine (3130.60 mg/kg), proline (2302.90 mg/kg), alanine (2088.10 mg/kg), glycine (1606.40 mg/kg) and lysine (1197.40 mg/kg). Especially, taurine was the most abundant of all free amino acids. Thus, these data indicate that krill seems to be abundant protein source food.

Journal of Environmental Science International, volume 23, issue 2, 2014, Pages 171~180
DOI : 10.5322/JESI.2014.23.2.171
This study provides the empirical results of the customers' necessity and intentions of purchasing weather index insurance using survey of asking the customers' recognition about weather insurance. In this article, we discovered that not only the customers' past experience of loss but also the extent of damage and the effects that change in weather would have on their firm are positively related to an intention to purchase weather index insurance. In addition, the level of premiums was significantly higher for the highly-intended group of willing to purchase weather index insurance than the comparison group.

In Korea, the chemical oxygen demand(
) in freshwater sediments has been measured by the potassium permanganate method used for marine sediment because of the absence of authorized analytical method. However, this method has not been fully verified for the freshwater sediment. Therefore, the use or modification of the potassium permanganate method or the development of the new
analytical method may be necessary. In this study, two modified
analytical methods such as the modified potassium permanganate method for
and the modified closed reflux method using potassium dichromate for
were compared. In the preliminary experiment to estimate the capability of the two oxidants for glucose oxidation,
were about 70% and 100% of theoretical oxygen demand(ThOD), respectively, indicating that
was very close to the ThOD. The effective titration ranges in
were 3.2 to 7.5 mL and 1.0 to 5.0 mL for glucose, 4.3 to 7.5 mL and 1.4 to 4.3 mL for lake sediment, and 2.5 to 5.8 mL and 3.6 to 4.5 mL for river sediment, respectively, within 10% errors. For estimating
recovery(%) in glucose-spiked sediment after aging for 1 day, the mass balances of the
among glucose, sediments and glucose-spiked sediments were compared. The recoveries of
were 78% and 78% in glucose-spiked river sediments, 91% and 86% in glucose-spiked lake sediments, 97% and 104% in glucose-spiked sand, and 134% and 107% in glucose-spiked clay, respectively. In conclusion, both methods have high confidence levels in terms of analytical methodology but show significant different
concentrations due to difference in the oxidation powers of the oxidants.

The direct-runoff of South Korea's representative dams (Soyanggang, Chungju, Andong, Daecheong, and Seomjingang) and precipitation were analyzed mainly with the evenly distributed spring rainfall events across the country for the last five years. For precipitation, an increasing was presented during the period 2008-2011, but did not continue to increasing 2012. The average precipitation of the five dams displayed a similar trend. Except for Chungju and Andong Dams, the trend of runoff was similar to the one shown in the precipitation. Despite the precipitation of 2009 increased, the runoff volume decreased for Andong and Chungju Dams. In addition, Chungju Dam remarkably showed a bigger runoff volume compared to other dams. As for the Sumjingang Dam, the runoff volume was the smallest, and the difference is as great as over 15-fold when compared to other runoff values. After the result of analyzing the relation between a single runoff event and synoptic weather patterns, pattern 4 contributed to the greatest impact on this event and weather patterns. The total runoff volume of the five dams for spring rain event for the last five years that exhibited this characteristic was estimated at 5.68 billion tons(
). Lastly, the value of this estimation was assessed as approximately 273.1 billion KRW.

Cho, Seok-Ho ;
Journal of Environmental Science International, volume 23, issue 2, 2014, Pages 207~218
DOI : 10.5322/JESI.2014.23.2.207
A ventilation model was developed for predicting the air change per hour(ACH) in buildings and the airflow rates between zones of a multi-room building. In this model, the important parameters used in the calculation of airflow are wind velocity, wind direction, terrain effect, shielding effect by surrounding buildings, the effect of the window type and insect screening, etc. Also, the resulting set of mass balance equations required for the process of calculation of airflow rates are solved using a Conte-De Boor method. When this model was applied to the building which had been tested by Chandra et al.(1983), the comparison of predicted results by this study with measured results by Chandra et al. indicated that their variations were within -10%~+12%. Also, this model was applied to a building with five zones. As a result, when the wind velocity and direction did not change, terrain characteristics influenced the largest and window types influenced the least on building ventilation among terrain characteristics, local shieldings, and window types. Except for easterly and westerly winds, the ACH increased depending on wind velocity. The wind direction had influence on the airflow rates and directions through openings in building. Thus, this model can be available for predicting the airflow rates within buildings, and the results of this study can be useful for the quantification of airflow that is essential to the research of indoor air quality(temperature, humidity, or contaminant concentration) as well as to the design of building with high energy efficiency.

The occurrence trends and moleculargenetic characteristics of noroviruses detected from gastroenteritis patients in Jeju from 2008 to 2010 were investigated. In addition, the norovirus contamination and its characteristics of groundwaters in Jeju were examined. The incidence caused by norovirus in viral gastroenteritis patients has increased every year and was higher in male than in female. The patients caused by norovirus occurred throughout all months. The incidences started to increase from November, were very high from December to February, started to decrease from March, and were very low from June to September. The patients caused by norovirus occurred throughout all ages, however, the infants below 5 years were the most susceptible to norovirus infection and the age group from teens to forties were the most insensitive to norovirus infection. The sequencing analysis showed that 18 genotypes (8 genogroup I (GI) and 10 genogroup II (GII)) were detected, the incidences caused by GI and GII were 11.5% and 88.5%, respectively, and predominant genotype was GII-4 (70.5%), which was the major genotype giving rise to norovirus incidences in Jeju, together with GII-3 (6.1%) and GI-4 (4.1%). Among 20 groundwaters sampled at 9 wells (4 non-drinking water wells and 5 drinking water wells), noroviruses were detected from 2 groundwaters sampled at one non-drinking water well and their genotypes were GI-5 and GI-8.

DOI : 10.5322/JESI.2014.23.2.239
This study investigated the effects of soil depths and soil organic fertilizer application on the growth characteristics of Spiraea bumalda 'Gold Mound' in a extensive green roof system. The treatments were 3 soil depths (10, 15 and 25 cm) and 5 soil types in mixture of artificial soil and organic fertilizer. We measured plant height, leaf width, leaf length, number of flowers, visual quality and survival rate from March to October in 2011. The growing medium of 10 cm soil depth showed the highest plant growth in
(amended soil 100%), and the lowest plant growth in
(organic fertilizer 20% + amended soil 80%) treatment. In case of 15 cm soil depth, Spiraea bumalda 'Gold Mound' showed a high leaf length and visual quality in
(organic fertilizer 33% + amended soil 67%) treatment and high leaf width and number of flowers in
(organic fertilizer 100%) treatment.
treatment without organic fertilizer showed the lowest leaf length and poorest visual quality, and
treatment showed the lowest plant height and lowest number of flowers. At soil depth 25 cm,
(organic fertilizer 50% + amended soil 50%) treatment showed greater plant height, visual quality and number of flowers than other treatments. The leaf length and leaf width were more effective in
treatment showed a relatively low leaf length, leaf width and visual quality. The higher the organic conditioner, the better the plant growth. And, survival rates of Spiraea bumalda 'Gold Mound' showed 92%, 88% and 76% at soil depths of 25 cm, 15 cm and 10 cm, respectively, in this a extensive green roof system. Therefore, the results showed that the growth of Spiraea bumalda 'Gold Mound' was affected by both soil quality and soil depth. Different optimal mixtures of organic fertilizer and amended soil were determined, depending upon soil depth.

DOI : 10.5322/JESI.2014.23.2.249
This paper investigates the characteristics of high
episodes occurred at Anmyeondo area in spring time, 2009. The monthly mean
concentration during April was the highest in the year and especially, high levels of
exceeding standard regulation level were sustained consecutively during 5 to 13 April. To analyze more detailed
characteristics, numerical simulations were carried out using CMAQ(Community Multi-scale Air Quality) with IPR(Integrated Process Rate) and DDM-3D(Decoupled Direct Method).
level was lower in daytime than that in nighttime due to vigorous vertical mixing during daytime. The chemical composition was showed that ratio of primary ion components such as sulfate(
) and ammonium(
) were nearly half of total amount of
. Aerosol and transport process dominantly contributed to
concentration in Anmyeondo area and contribution rate of local emissions was nearly zero since Anmyeondo area has rare anthropogenic PM emission sources. DDM-3D analysis result showed that
in Anmyeondo area was influenced by emissions from Shanghai and Shandong region of China.

DOI : 10.5322/JESI.2014.23.2.261
This work investigates the relationship between the sea breeze circulation and ozone concentrations during cold water events in the southeastern coastal area of the Korean Peninsula, where coastal upwelling frequently occur. This analysis was performed based on the classification of two categories, such as cold water and non-cold water events, over the period of 2000-2009. The low air temperature (
), low SST (
) and the wind direction(southerly) are the features of the cold water events in the Southeastern coastal area. Moreover, ozone concentrations in the cases of the sea breeze circulation and cold water events were significantly lower (below 30 ppb) than those (70~100 ppb) in the non-clod water events, because of the low air temperature (
) and high wind speed (3~5 m/s) around the southeastern coastal area.

Asian dust (or yellow sand) occurring mainly in spring in East Asia is affected by the distribution of weather systems. This study was performed to investigate the characteristics of suspended particulate for Asian dust at Busan, Korea in 20 March 2010, which was one of the extreme case for the last 10 years. There was used the data of weather chart, satellite, automatic weather system (AWS),
, laser particle counter (LPC), and backward trajectories model. In synoptically, the high pressure was located in the northwestern part and low pressure was located in the northeastern part of Korea. The strong westerly winds from surface to upper layer makes it possible to move air masses rapidly. Air masses passing through Gobi Desert in Mongolia and Inner Mongolia plateau covered the entire Korean peninsula. As the results of aerosol analysis,
concentration at Gudeok mountain in Busan was recorded
in 2300 LST 20 March 2010 and their concentration was markedly increased at coarse mode particle. In surface condition, westerly wind about 3 ~ 5 m/s was dominant and small particles of
were distributed on the whole. In heavy metal components analysis, the elements from the land was predominated.

Journal of Environmental Science International, volume 23, issue 2, 2014, Pages 291~302
DOI : 10.5322/JESI.2014.23.2.291
We have studied characteristics of community structure on the benthic macro-invertebrates at twelve selected sites in upstream, midstream and downstream of Paemsagol, Piagol, Chilseongol and Daeseonggol, major streams of Jirisan Mountain, for three years from April 2008 to September 2010. As a result, 2 phyla, 3 classes, 11 orders, 41 families, 119 species and 4,449 individuals of benthic macro-invertebrates have been collected and classified in this study. Among them EPT group (Ephemeroptera, Plecoptera, Trichoptera), commonly appearing taxa in clean stream ecosystem, was found most frequently. The highest species number of benthic macro-invertebrates were collected in 2008, the year with lower climatic influence including heavy rain. In almost all of survey sites 80% or over of EPT group were counted, and St. 1 scored highest rate of EPT group at 92.59%. Most dominant species was Ecdyonurus kibumensis at 12.83% of dominance index, and subdominant species was Goerodes KUb at 6.81% of dominance index. The investigation of the feeding function group indicated that gathering-collectors were dominant with 26 species and 1,334 individuals, while the number of filtering-collectors was lowest with 11 species and 230 individuals. This result represents that the feeding function group of Jirisan Mountain is mountainous stream-specific one. Both diversity index and richness index were lowest at the midstream of Chilseongol (St. 5), while the midstreams of Daeseonggol (St. 11) and Piagol (St. 8) were highest in diversity and richness indices respectively. The analyses of linear regression and correlation were performed in order to investigate and to predict the appearance aspect of EPT group by altitude. The results showed that the ratio of Plecopteran species number has increased by the elevation of the altitude at 0.05 significance level. Cluster analysis was also carried out for evaluating environmental similarities among survey sites. As a result, upper regions of Paemsagol (St. 1) and Piagol have clustered as most similar sites each other, while the midstream of Piagol (St. 8) has separated with lower similarity value than other sites in species composition.

As for chemical characteristics of cultivated media waste, the total content of nitrogen, phosphoric acid, and potassium was 6.93%; organic matter content was 67.78%; pH and EC were 7.20 and 1.46 ds/m, respectively. Organic acids identified during stabilization included citric acid, oxalic acid, fumaric acid, and acetic acid, which was highest. During the stabilization of cultivated media waste, temperature decreased and pH increased on the 15th day, and the germination index was 88 after the period, indicating that at least 15 days of stabilization is needed when cultivated media waste is used for growth material of crop. As for germination characteristics, when the mixture rate of cultivated media waste was 20% and under, germination of cucumber and oriental melon was favorable without difference compared to the control plots. For lettuce and Chinese cabbage, no statistically significant difference was found when the rate was 10% and under compared to the control plots. As for seedling quality after 20 days of sowing, cucumber, oriental melon, and Chinese cabbage showed favorable growth only when the mixture rate of cultivated media waste was 10% and under; lettuce showed lower growth characteristics regardless of mixture rate when compared to the control plots. Cultivated media waste may be significantly useful for cucumber and oriental melon, but not for Chinese cabbage and lettuce.

DOI : 10.5322/JESI.2014.23.2.313
To investigate the effects of octylphenol and nonylphenol on the reproduction of the striped field mouse, the mice were subcutaneousely injected with 4-t-octylphenol 800 mg/kg (OP800), nonylphenol 900 mg/kg (NP900) or OP800 + NP900 (OPNP), respectively, in two times a week for 2 months. As the results, there were no differences between the control and the compound-treated groups in the body weight in both sexes, and the GSI (gonadosomatic index) and SVI (seminal vesicles index) in the adult males. But histological abnormalities of the reproductive organs in the mice seems to be related to the compound. This suggestion is supported by the facts that most mice treated with the compounds had only a small number of spermatozoa in the shrunken epididymal tubules. In addition, the shrunken reproductive organ in one mouse treated with the NP, suggests that the abnormalities in the wild striped field mice might be induced by the compound. Furthermore, it is indicated that the compounds must be toxicants to inhibit pregnancy, judging from the fact that all the mice treated with the compounds had failed to deliver.

Journal of Environmental Science International, volume 23, issue 2, 2014, Pages 331~333
DOI : 10.5322/JESI.2014.23.2.331
We investigated the effects of sea urchin shell powder on 2 volatile fatty acids, acetic and butyric acid, in poultry litter. A total of 60 1-d-old male broiler chicks (Arbor Acres) were allocated to 2 treatments (basal diet and 1% sea urchin shell powder) with 3 replicates of 10 birds each. During the 4-week experimental period, significant differences in acetic acid and butyric acid concentrations were observed between treatments (P < 0.05), except for acetic acid at 1 week. Additions of 1% sea urchin shell powder resulted in lower acetic and butyric acid concentrations compared to the litter of control birds. We conclude that the sea urchin shell powder used in this study might prove beneficial in reducing environmental pollution caused by poultry litter.
