  • The seaweed processing industry in Korea has developed since the late of 1970s, motivated by exports of salted seaweed to the Japan market. However, due to the keen competition of Korean salted and dried seaweed with chinese products in the japan market, exports of Korean seaweed have been in the decreasing. It also has promoted the restructuring of the seaweed processing industry itself as follows: first, the processing type has been changed from the slated seaweed processing to the dried seaweed processing. Second, domestic markets for seaweed have been significantly expanded. This study is aimed to investigate some problems that the seaweed processing industry currently faces and to provide responding strategies for its development by analyzing a background, characteristics, and business types in the Wando region of Jeollanamdo that is a primary region of the seaweed processing industry in Korea. The background that the seaweed processing industry in Wando region could be started and developed is that first, small and mid-size salted seaweed processing companies have grown fast due to the exports to the japan market. Second, various business conditions, including seaweed materials, labors that are very important factors for the seaweed processing were more suitable compared to other regions. As characteristics of the seaweed processing industry, it shows that small-scale companies have a larger decreasing rate in sales and over 85% companies process seaweed together with other materials such as kelp, etc. The biggest problem that the seaweed processing industry has is that it has not timely responded to changes in domestic and international markets. Therefore, it is very important to cope with market changes by both introducing an aquaculture outlook service for seaweed and promoting higher value-added products and demands through publicities.

  • Purpose : The purpose of this study was to investigate the differences in social quotient and sensory processing function between completed-toileting and incomplete-toileting children with autism spectrum disorder (ASD). We aims to provide a basis for the training of children with autism spectrum disorders. Methods : The subjects of this research were children with ASD, aged from 4 to 7, receiving sensory integration therapy at the H-Child Development Research Center in Busan, South Korea. After recruiting 30 parents who had children with ASD, we interviewed them and we divided their children into completed-toileting group and incomplete-toileting group based on the past researches. We assessed them using the Social Maturity Scale and Sensory Profile. Spearman correlation was used to analyze between the sensory processing score and social quotient. Mann-Whitney U test was used to compare the Sensory Profile scores of the two groups. Results : The social quotient was correlated with the sensory processing score in the most of component as for auditory processing, vestibular processing, touch processing, multisensory processing, orosensory processing, except for visual processing. The groups of completed-toileting and incomplete-toileting group showed statistically significant intergroup difference in sensory seeking, emotional reactive, oral-sensory sensitivity, and inattention/distractibility in the sensory factor region. No statistically significant difference from intergroup was observed in any modulation areas, nor in behavioral & emotional response domains. Conclusion : A significant intergroup difference was observed in the most of sensory processing areas, except for modulation areas and behavioral & emotional response domains. The result revealed that toileting is significantly correlated with sensory processing. Therefore, this study suggests that the sensory processing function should be considered in the toilet training of children with ASD.

  • A single machine scheduling problem for jobs with stochastic processing time is considered in this study. Shortest processing time (SPT) sequencing according to the expected processing times of jobs is optimal for schedules with minimal expected mean flow time when all the jobs arrive to be scheduled and their expected processing times are known. However, SPT sequencing according to the expected processing time may not be optimal for the minimization of the mean flow time when the actual processing times of jobs are known. This study evaluates the complexity of SPT sequencing through a comparison of the mean flow times of schedules based on the expected processing times and actual processing times of randomly generated jobs. Evaluation results show that SPT sequencing according to the expected flow time exhibits chaotic variation to the optimal mean flow time. The relative deviation from the optimal mean flow time increases as the number of jobs, processing time, or coefficient of variation increases.

  • The objective of this study was to evaluate the characteristics of melanoidins formed from black garlic (BG) after different thermal processing steps. The melanoidins formed from BG during thermal processing were produced in large amounts, and the initial (280 nm), intermediate (360 nm), and final stage product (420 nm) had similar tendencies. Compounds like degraded proteins, peptides, and phenolic acids were present in the melanoidins during thermal processing. All the melanoidin samples showed different absorptions in the UV-visible spectra, although these had similar shapes. Moreover, the carbon, hydrogen, and oxygen content of melanoidins formed from BG during thermal processing decreased initially, and then increased. However, the nitrogen content increased during thermal processing. As thermal processing progressed, the molecular weight of all the melanoidin samples showed increasing intensities, whereas the major peaks of each melanoidin sample had different retention times. Furthermore, the melanoidins formed from BG after different thermal processing steps contained -OH, -CH, amide I, and III groups. The crystallinity of the melanoidins was majorly formed at $31.58^{\circ}$ and $43.62^{\circ}$ ($2{\theta}$).

  • Due to the rapid growth of the amount of data, research on bigdata processing has been highlighted. For bigdata processing, CUBRID Shard is able to support query processing in parallel way by dividing the database into a number of CUBRID servers. However, CUBRID Shard can answer a user's query only when the query is required to gain accesses to a single CUBRID server, instead of multiple ones. To solve the problem, in this paper we propose a CUBRID based distributed parallel query processing system that can answer a user's query in parallel and distributed manner. Finally, through the performance evaluation, we show that our proposed system provides 2-3 times better performance on query processing time than the existing CUBRID Shard.

  • On mobile devices, image sequences are widely used for multimedia applications such as computer vision, video enhancement, and augmented reality. However, the real-time processing of mobile devices is still a challenge because of constraints and demands for higher resolution images. Recently, heterogeneous computing methods that utilize both a central processing unit (CPU) and a graphics processing unit (GPU) have been researched to accelerate the image sequence processing. This paper deals with various optimizing techniques such as parallel processing by the CPU and GPU, distributed processing on the CPU, frame buffer object, and double buffering for parallel and/or distributed tasks. Using the optimizing techniques both individually and combined, several heterogeneous computing structures were implemented and their effectiveness were analyzed. The experimental results show that the heterogeneous computing facilitates executions up to 3.5 times faster than CPU-only processing.

  • Objective: The objective of this research was to study the electrical properties and quality of frozen-thawed chicken breast meat and to investigate the relationship between these parameters at different times of frozen storage. Methods: Thawed samples of chicken breast muscles were evaluated after being kept in frozen storage at $-18^{\circ}C$ for different periods of time (1, 2, 3, 4, 5, 6, 7, and 8 months). Results: The results showed that water-holding capacity (WHC) and protein solubility decreased while thiobarbituric acid-reactive substances content increased with increasing storage time. The impedance module of samples decreased during 8-month frozen storage. Pearson correlation coefficients showed that the impedance change ratio (Q value) was significantly (p<0.05) related to pH, color, WHC, lipid oxidation and protein solubility, indicating a good relationship between the electrical properties and qualities of frozen-thawed chicken breast meat. Conclusion: Impedance measurement has a potential to assess the quality of frozen chicken meat combining with quality indices.

  • Recently, researches for military purposes such as precision tracking and mission completion using UAVs have been actively conducted. In particular, if the posture information of the leading UAV is estimated and the mission UAV uses this information to follow in stealth and complete its mission, the speed of the posture information estimation of the guide UAV must be processed in real time. Until recently, research has been conducted to accurately estimate the posture information of the leading UAV using image processing and Kalman filters, but there has been a problem in processing speed due to the sequential processing of the processing process. Therefore, in this study we propose a way to improve processing speed by applying methods that the image processing area is limited to the ROI area including the object, not the entire area, and the continuous processing is distributed to OpenMP-based multi-threads and processed in parallel with thread synchronization to estimate attitude information. Based on the experimental results, it was confirmed that real-time processing is possible by improving the processing speed by more than 45% compared to the basic processing, and thus the possibility of completing the mission can be increased by improving the tracking and estimating speed of the mission UAV.
