Soybean is an important plant as it is the source of protein and oil as well as various phytochemicals that are related with biological activity. Over the past decades, scientists have conducted considerable research on the physiological properties of soybeans, especially isoflavones, which are the characteristic components in soybeans. However, there is no research on the properties or the bio-functionality of soybean leaf. Jangachi and kimchi are two of the traditional special dishes of Gyungsang Province in Korea which we made from soybean leaves. Depending on the recipe, green or yellow soybean leaves are used for the preparation of these two side dishes. We compared the antioxidative activity and measured the contents of isoflavones, total phenol, chlorophylls, carotenoids, and vitamin C in the ingredients (green and yellow soybean leaf) and the final side dishes (jangachi and kimchi). We Int report that isoflavones were contained in soybean leaf and that jangachi had the highest isoflavone contents among the samples. Yellow soybean leaf contained higher isoflavones than green soybean lear and kimchi. From the TEAC assay results, the sequence or antioxidative activities was yellow soybean leaf > soybean leaf jangachi > green soybean leaf > soybean leaf kimchi. The sequence was the same with total phenol contents, indicating that antioxidative activity is highly related with total phenol level. Chlorophylls, carotenoids and vitamin C existed abundantly in green soybean leaf. In conclusion, soybean leaf could be a good material for health due to the presence of isoflavones and the other useful antioxidants mentioned above.

This paper is written in order to investigate how Lee Je-Ma changed traditional Zhu Xi's philosophical view on Way(Tao; 道) Virtue(De: 德) Nature(Xing;性) and Imperative(Ming; 命), which was general concepts of his contemporary age, to practical philosophy and created new medical theories of Sasang(4 symbols) science from it. Lee emphasized the true thing which is able to be done in one's living not the concepts of Sasang. So he induced the concepts of Way and Virtue from the easy and simple way(易簡之道) in the Classic of Changes(I'Ching) for the purpose of practice by anyone. Because Nature and Imperative are derived from Way and Virtue in the context logically, human life is virtual in itself, so the substance of Nature and Imperative became equal with Way and Virtue. Herein the names and concepts of original 'Sasang' were substituted to Business(事), Mind(心), Body(身), Thing(物) which is able to be directly related with human being in his daily life. And he explained variously about the responses of Mind and Body of individuals onto Business and Thing. So it could be applied in medical aspects like emotional, symptomatical, characteristic features. Conclusively man is virtual being, so Nature and Imperative in the level of Human being are based on Way and Virtue in the level of Heaven. For that reason the new concepts of Sasang Business. Mind. Body Thing or Heaven. Human. Nature and Imperative were proposed.

This study investigates, through the Ka-rae-ban-cha-do(가예반차도) in the Ka-rae-do-gam­eui-gue (가예도감의궤), how the system of costume used in ceremony exchanged during the middle, late the Yi dynasty and in the period of introducing Wastern civilization. The procedure of the royal marriage is also studied here. The procedures of Ka-rae were divided into the six traditional etiguettes(륙예) : Nap-che (납채) , Nap-gyng(납징), Go-gi(고기), Chaik-bi(책비), Chin-young(친영), and Dong-roe(동뢰). The change of the general structure and characteristic of the costume used in the ceremony in Ka-rae-ban-cha-do are as follows: The costume in Ka-rae-ban-cha-do can be divided into the Guard costume (호위복식) and the Ceremonial arms costume (의장복식). The most formal attire of the Guard costume, Yangkwan-Chobok (양관-조복) and Samo -Danryeong(사모-단령) with Huygpai(흉배) can be seem only in the Ka-rae of late king's. Of the Ceremonial arms costume, the most outstanding was Hongkun- Hongeui (홍건-홍의), which showed up in almost all Ka-rae-ban-cha-do. Heukkun-Changos$\cdot$Deogrei (흑건-창옷$\cdot$더그레) were worn as well. In the style of costume emphasis convenience and practicality rather than on beauty, because they had to carry the arms used in ceremony with them nevertheless by using primary colors it was very colorful. This costume in Ka-rae-ban-cha-do has little difference, but great changes are shown in Sunjongsunjongbi Ka-rae-ban-cha-do (순종순종비가례반차도). Most costume of the past was replaced with western hat and suit, so the duplicate state of our costume and western costume came into existence during the period of introducing western civilization.

Today, the development of innovative technologies is accompanied by changes in the industrial structure and the Big Blur phenomenon, where the boundaries in various fields are blurred. The purpose of this study was to view the Big Blur phenomenon as a big paradigm shift in the 21st century and derive environmental changes and characteristics of the Korean fashion market. The research method included an analysis of the fashion brands after 2015. Through this study, we intended to establish a framework for understanding the changes in the fashion market from the perspective of Big Blur and discuss the direction of brand marketing. The research results showed the hyperlinks, connectivity, openness, homeostasis, synchronicity, mobility, interactivity, and brand experience of online and offline spaces beyond the boundaries of virtual space and offline physical spaces such as online physical and spatial viewpoints. It also showed the characteristics. The characteristics from the socio-cultural point of view were characteristic of diversity, mixture, coexistence, composability, and pluralism beyond the traditional socio-cultural and regulatory scopes. Hip hop fashion, street fashion, unisex, genderless, androgynous fashion, and kid fashion are the backbone of the Big Blur and are becoming important factors in fashion. The characteristics of the market and economic viewpoint are prosumers that play roles both as producers and consumers. It shows the extensibility of consumers as producers, the cohesiveness of producers and consumers, the cooperation, and the interconnectivity.

In this study, Seolgi Tteok was made in order to increase consumption of Geuk, which possesses numerous nutritional advantages, and its optimum content as a new food coloring for rice cake was determined. Quality characteristics and quantitative description analysis (QDA) of Seolgi Tteok, in which Geuk was added at 0, 4, 8, and 12%, was conducted. Consumer acceptability test was also conducted. As the amount of added Geuk increased, moisture content of Seolgi Tteok increased as well. Brightness (L-value) was the highest in the control group, and more Geuk resulted in higher values of red index (a-value) and yellow index (b-value), which corresponded to the results of the sensory evaluation. As result of the mechanical texture measurement, only adhesiveness and resilience show a significant difference. As a result of the QDA, 17 sensory characteristic terms were assessed. Among them, only 13 showed a significant difference. Among the different sensory characteristics, almost all of them except for taste characteristics were significantly influenced by the amount of Geuk. The aroma and taste of Geuk were not largely influenced. It can be suggested that Geuk is not a factor that strongly influences flavor. In conclusion, Geuk does not have a strong influence on the taste or aroma of Seolgi Tteok but does on color characteristics. It can be suggested that Geuk is qualified as a coloring material for food, and the reasonable addition amount is 8%. As a result of this research, Geuk can be considered as a coloring material for other types of rice cake, traditional Korean sweets, and even confectioneries as well as for Seolgi Tteok. This implies that Geuk can be utilized to develop various new products as a coloring material with abundant nutritional content, which will contribute to the promotion of Geuk consumption.

Methamphetamine (MA) is currently the most abused illicit drug in Korea. MA is produced by chemical synthesis, and the final target drug that is produced contains small amounts of the precursor chemicals, intermediates, and by-products. To identify and quantify these trace compounds in MA seizures, a practical and feasible approach for conducting chromatographic fingerprinting with a suite of traditional chemometric methods and recently introduced machine learning approaches was examined. This was achieved using gas chromatography (GC) coupled with a flame ionization detector (FID) and mass spectrometry (MS). Following appropriate examination of all the peaks in 71 samples, 166 impurities were selected as the characteristic components. Unsupervised (principal component analysis (PCA), hierarchical cluster analysis (HCA), and K-means clustering) and supervised (partial least squares-discriminant analysis (PLS-DA), orthogonal partial least squares-discriminant analysis (OPLS-DA), support vector machines (SVM), and deep neural network (DNN) with Keras) chemometric techniques were employed for classifying the 71 MA seizures. The results of the PCA, HCA, K-means clustering, PLS-DA, OPLS-DA, SVM, and DNN methods for quality evaluation were in good agreement. However, the tested MA seizures possessed distinct features, such as chirality, cutting agents, and boiling points. The study indicated that the established qualitative and semi-quantitative methods will be practical and useful analytical tools for characterizing trace compounds in illicit MA seizures. Moreover, they will provide a statistical basis for identifying the synthesis route, sources of supply, trafficking routes, and connections between seizures, which will support drug law enforcement agencies in their effort to eliminate organized MA crime.

The objective of this study was to standardized the cooking method of Imjasootang, a traditional health food in summer. By mixing chicken soup with 20 g (I$_1$), 30 g (I$_2$), 40 g (I$_3$), 50 g (I$_4$) of seasam seeds, the distinctive characteristic and level of preference of Imjasootang were examined through the analyses of the proximate composition, fatty acid contents, color index, turbidity, brix$^{\circ}$, and sensory evaluation. 1. The proximate composition of Imjasootang was 90.2∼95.1% of total moisture, 0.985∼1.271% of crude protein, 0.90∼0.98% of crude fat, 1.592∼2.456% of nonfiber, 0.003∼0.004% of fiber, and 0.77∼0.97% of crude ash. Fatty acid were composed of 15.15∼17.36% of saturated fatty acid and 79.73∼82.54% of unsaturated fatty acid. Imjasootang contains high level of oleic acid and linoleic acid which were dependant on the content of seasame seeds. 2. For color index of samples, the lightness ranged 47.2∼56.9, “a”values 1.82∼2.15%, and “b”values 15.5∼16.5%. The turbidity of samples ranged 39∼61%, in which I$_4$ (chicken stock 100 g+sesame seed 50 g+water 25 g) was the most turbid. Solid content was also the highest in I$_4$, ranging 1.4∼5.1%. 3. In sensory evaluation, all sesame seed Imjasootangs had no significance differences in appearance. The higher the level of sesame seed in Imjasootangs, the more Imjasootang was preferred in terms of nutty aroma, color nutty taste. and viscosity. I$_4$ had the strongest nutty aroma. I$_2$ (chicken stock 100 g+sesame seed 30 g+water 15 g) and I$_3$ (chicken stock 100 g+sesame seed 40 g+water 20 g) were the best in the overall preference.

대용량 볼륨 데이타를 가시화하는 효과적인 방법인 후-정열 병렬 렌더링은 부하균형에 의해 성능이 결정된다. 기존의 정적 데이타 분할 방법은 태스크 병렬성만의 관점에서는 자기균형을 쉽게 얻을 수 있었지만, 데이타 내부의 빈 공간을 고려하지 않았기 때문에 데이타 병렬성의 관점에서는 심각한 불균형을 초래할 수 있었다. 본 논문은 태스크 병렬성과 데이타 병렬성이 함께 고려된, 적응적이며 확장적인 부하 균형 기법을 제안한다. 우리는 계층적 자료 구조인 옥트리와 BSP-트리를 효과적으로 결합하여 볼륨 데이타의 실제 영역만을 추출하여 렌더링 노드들로 균등하게 분산시켰으며, 각 렌더링 노드들에서는 3차원 클러스터링 알고리즘을 적용하여 렌더링 순서를 효과적으로 결정하였다. 제안하는 방법은 기존의 정적 데이타 분산 기법에 비해 최대 22배의 병렬성을 높였고 동기화 비용을 낮추어 렌더링 성능을 크게 향상시켰음을 실험을 통해 알 수 있었다.

본 글은 한 사회에서 가족책임주의가 발현되는 양태로서 돌봄 제공방식의 유형화에 대한 이론적 검토를 했다. 먼저 국내외에서 혼란스럽게 사용되고 있는 가족주의와 가족책임주의를 구분했다. 이러한 구분을 통해 본 연구는 가족책임주의가 부분적으로 복지국가의 미발달로 인해 나타나는 현상이지만(과도기적 가족책임주의), 한 사회의 돌봄 제공방식을 규정하는 준거(준거적 가족책임주의)로 영향을 미치고 있다고 주장했다. 특히 가족책임주의가 돌봄 제공방식을 통해 발현되는 양태를 탈가족화와 가족화, 공적책임과 사적책임이라는 두 축을 통해 6가지의 전형적 유형화가 가능하다는 것을 논거 했다. 이러한 논의에 근거하면 한국에서 가족책임주의가 발현되는 양상은 단순히 복지국가의 미발달로 인한 결과가 아니라 한국사회의 습속으로 자리 잡고 있는 가족책임주의가 한국 사회의 돌봄 제공방식에 중요한 영향을 미친다는 추정이 가능하다. 이는 한국사회가 아무리 돌봄과 관련해 탈가족화의 제도적 인프라를 확충한다고 해도 한국사회가 북유럽 복지국가들의 돌봄 제공방식과 유사해 질 수 없다는 것을 의미한다.
