Korean Journal of Environmental Health Sciences, volume 4, issue 1, 1977, Pages 1~9
The survey on the sanitary conditions to the water supply facilities, privy facilities and disposal methods of human excreta in Sindong area of Choonseung-gun, Kangwon Province was carried out during 7 months from May to November, 1976. The results of the survey are as follows. 1) The pump-wells are used in the 1,185 households as 66.7% of 1,775 and are almost private. 2) The materials of drainage floors and drainage are almost cement, and the drainages are good condition. 3) Most parts of dug-wells have been used beyond 9 years after installation, and disinfection of water has not been carried out in the case of 68.1% of total wells. 4) Objectives of water use to the number of households as 60.2% are drinking, kitchen and cleaning. 5) Water consumption per capita day is estimated to be about 22.7% litters. 6) 1,521 households as 85.7% of total 1,775 possess their private privies and the numbers as 80.6% of the private privies are located outside the houses. 7) The privies are needed to be improved much more in the view point of excreting to the ashpile instead of the septic tank in the case of 39.2% of total households. 8) Human excreta as manure are used to the field in the number of households as 82.4 of total 1,316.
A study on the Detection of Artificial Dyes in the Commercial Jellys by Use of Paper Chromatography and Thin-Layer Chromatography.
Korean Journal of Environmental Health Sciences, volume 4, issue 1, 1977, Pages 10~12
A study was carried out to detect of illegal artificial dyes and to confirm the used rate of illegal dyes in the production process of commercial jellys by thindayer chromatography and paper chromatography, from March, 1976 to July, 1976. The following conclusions were obtained 1. Seperated dyes were amaranth, erythrosin, tatrazin, sunset yellow FCF, fight green SF yellowish, fast green FCF and the most frequent use of amaranth. 2. Used rate of legal dyes were 94.12% (96 samples) and illegal dyes were 5.88% (6 samples) with samples 102. 3. The average Rf value of T.L.C. were amaranth (0.92), erythrosin (0.48), tatrazin (0.83), sunset yellow FCF(0.86), fast green FCF (0.63), light green SF yellowish (0.23) and paper chromatography were amaranth (0.76), erythrosin (0.44), tatrazin(0.75), sunset yellow FCF (0.76), fast green FCF (0.86), light green SF yellowish(0.52).
A Study on the Health Status of Some Industrial Workers in Seoul.
Korean Journal of Environmental Health Sciences, volume 4, issue 1, 1977, Pages 13~22
In an attempt to evaluate working conditions and hazardous environmental factors, a survey on health problems was conducted for 721 employees from 18 industrial plants in Young Dung Po and Sung Dong districts of Seoul in the period from May 1975 to Feb, 1976. The questionnaire and survey was inclusive of all illnesses known as most common to industrial workers (according to the report by Korea Industrial Health Association) of this country and envi ronmental factors pointed out by the workers. The results were as following. 1. The over whelming majority of complaints were psychiatric, ear,eye, and digestive disorders. 2. Those whose work time is the longest have a propotionately higer incidence of complaints especially in eye,ear, neuromusculoskeletal, and neurosensory systems. 3. In females whose occupational history is relatively short, a higher incidence of digestive and skin section disorders was noted and this is especially true among those working in night shift. 4. Among machinery industry workers, most complaints were of eye, ear, and neuro musculoskeletal disturbances, and this fact seems to be closely related to physical over works. 5. Dust and noise were pointed out by the largest number of workers as undisirable conditions in work environment. 6. Distribution of complaints are closely related to the type of industry, and in comparison with the result reported by Korea Industrial Health Association in 1972, the prevalence rates of occupational disorder were similar in our study,
The Studies on the Transaminase Activities(1)
Korean Journal of Environmental Health Sciences, volume 4, issue 1, 1977, Pages 23~25
Transaminase has been a popular methods in the clinical laboratory for the diagnosis of particular diseases. The methods we are familiar with should be considered further on the serum states provided on the test to be done. (serum freshness, temperature and duration preserved) I have studied transaminase activities of the serum preserved under frozen (-10$\circ$C), refrigerated (4$\circ$C) and room temperature conditions. At a given interval those activities of serum are measured and then the results are compared with the optical density and calculated for the standard deviation and percent variation (Table 1. & Fig. 1.) G.O.T. activity is maintained decreased at a relatively constant rate from 2nd day to 14th day preservation under frozen and refrigerated but its activity variation at 25$\circ$C are far greater than the above conditions throughout the test periods. Elevated G.P.T. level of serum compared with G.O.T. are remained at any temperature and duration. Unless the determination of amino acid level study can not ruled out clearly.

Korean Journal of Environmental Health Sciences, volume 4, issue 1, 1977, Pages 41~46
Main objectives of this survey were to find out general sanitary status of water source, draining status and toilet in Shindong Myun, Chungseong Gun. Interviewers of fourteen students visited 1,775 households in this Myun, filled the survey form and checked sanitary conditions of the areas from September 1 to November 30, 1974. Results are summarized as follows: 1. Draining state of pumps is better than that of wells and also the the quality of water sources are better in pumps than in wells. Wells and pumps of 54.1% were constructed more than five years ago. 2. About 66.7% use pump water, 10.5% well water and 8.3% simple piped drinking water system and average water consumption is 22.7l per day per capita. Private water system is 66.0% while public system 27.1%. 3. Water is used for drinking, washing body and cleaning at 53.8% while only for drinking at 7.4%. 4. Nearest pollution sources of drinking water are mainly toilets and stables, and average distances between them are less than ten meters. 5. Toilets of 78.3% are used only by one households and those of 12.9% by two. 6. Toilets of 10.9% are inside main building while those of 85.4% outside main building. 7. Toilet tanks are covered only at 6.3% households while not covered at 95.4%. The contents of tanks are removed about twice a month (40.2%), and 84.1% use them as fertilizer on their own farm and contents of 10.1% are removed by other people. 8.

The Study on the Enzyme Activities in Korean Bee Honey
Korean Journal of Environmental Health Sciences, volume 4, issue 1, 1977, Pages 47~50
This report is intended to describe as brief as possible the result of study on purity of the Korean Bee Honey. Purity of bee honey was measured by scaling the enzyme activities of two different honey groups: such as, the standard group and control group each including the samples of honey originated from the resource of acarcia, chestnut or miscellaneous origin. The samples of honey were collected from different sources: to wit, honey belonging to the standard group were collected from the township of Seoboo, Yangju county, Kyunggido province, Korea, while honey belonging to the control group were collected from the street side shops, market or the companies producing the secondary food from honey. The results of this study were summarized as follow: 1. It was found that honey belonging to the standard group contained less moisture than those belonging to the control group. Republic of Korea Ministry of Health and Social Affairs Food Control Regulation stipulates that honey must contain moisture less than 20%. The samples of' both groups contained moisture more than 20%, although honey belonging to the control group were relatively more so than honey belonging to the standard group. 2. Honey belonging to the standard group were found stronger in sugar reduction activities than those belonging to the control group. It was also noted that honey of acracia origin was strongest in reduction activities of the three different origin in the same group. 3. $\alpha$-Amylase and $\beta$-amylase were discovered to have activated more strongly in honey belonging to the standard group than those belonging to the control group. The enzyme activitie, varied depending on the origin of plant where honey comes from. For instance, honey of miscellaneous origin indicated the strongest activities in $\alpha$-amylase while honey of chestnut origirt indicated strongest in $\beta$-amylase.
