This study aims to analyze the spatial characteristics of a group of samurai residences among other traditional Japanese villages and to accumulate the village-level sample data of a residential group, which can serve as the foundation for a wide range of discussions. Using data that had been gathered since 1989, this study draw up a prototype floor plans to analyze the indoor spatial features of the residences in the modern period, and sampled 35 samurai houses. The following are the results of this study. The general characteristics of traditional Japanese houses were found among many Izumi Fumoto samurai residences up until the early Meiji period. However, after gradually the floor plan became more and more simplified; connections between rooms were reduced, decreasing their flexibility; and there was a rise in the number of houses with a larger area devoted to the Nando, a room for women and family members. The access of a visitor involved changes in one's eye-level view and established physical and psychological boundaries, which this study conjectures was used as a method to ensure that the visitor recognized the authority of the patriarch and to raise the family's reputation. As their floor plan was simplified, Izumi Fumoto samurai houses established one's eye view, boundaries, and procedures as a way to enhance the authority of the man of the family and the family's reputation. In addition, while there was an increasing number of residences that expanded the area of the Nando, in which family members slept and used the space in a stable way, they maintained the exclusivity of private space and did not clearly show who would use it.

The Lauraceae family has commercial uses, such as in the food, pharmaceutical, and perfume industries. This study was conducted to investigate anti-asthmatic activity of essential oils from the seven species in the Lauraceae family. The essential oils were extracted from the leaves of seven species, and the chemical composition was investigated by gas chromatography-mass spectrometry. The major constituents of essential oils differed depending on the species, even if they belonged to the same family. The main constituents were camphor (89.09%) in Cinnamomum camphora, linalool (26.91%) in Cinnamomum cassia, 1,8-cineole (23.90%) in Cinnamomum japonicum, d-limonene (10.27%) and β-eudesmol (10.03%) in Lindera obtusiloba, δ-cadinene (13.85%) and α-phellandrene (11.57%) in Machilus japonica, cis-,trans-β-ocimene (13.80% and 12.06%) and elemol (11.46%) in Neolitsea aciculata, and cis-β-ocimene (37.94%) and sabinene (24.91%) in Neolitsea sericea. The anti-asthmatic activity of essential oils was investigated using the lipopolysaccharide-induced NCI-H292 cells. The relative expression levels of the pro-inflammatory cytokines [interleukin (IL)-1β and IL-6] and mucus gene (MUC5AC and MUC5B) were significantly reduced by essential oils from seven species in the Lauraceae family. Among the seven essential oils, the essential oil from L. obtusiloba had the most superior anti-asthmatic activity. These results suggest that the essential oil of L. obtusiloba leaves could be used as an agent to suppress mucus hypersecretion.

Dietary proteins influence colorectal cancer (CRC) risk, depending on their quantity and quality. Here, using pyrosequencing, we compared the fecal microbiota composition in Balb/c mice fed either a normal protein/carbohydrate diet (ND, 20% casein and 68% carbohydrate) or a high-protein/low-carbohydrate diet (HPLCD, 30% casein and 57% carbohydrate). The results showed that HPLCD feeding for 2 weeks reduced the diversity and altered the composition of the microbiota compared with the ND mice, which included a decrease in the proportion of the family Lachnospiraceae and Ruminococcaceae and increases in the proportions of the genus Bacteroides and Parabacteroides, especially the species EF09600_s and EF604598_s. Similar changes were reported in patients with inflammatory bowel disease, and in mouse models of CRC and colitis, respectively. This suggests that HPLCD may lead to a deleterious luminal environment and may have adverse effects on the intestinal health of individuals consuming such a diet.

The composition of glasses to be suitable for crystallisation of $BaTiO_3$ by heat-treatment and the dielectric properties of the glass-ceramics were investigated. The composition of the family of glasses was defined by the formula $\chi$ $BaTiO_3 + (100-$\chi$)Al_2O_3$.$2SiO_2$ and excess BaO. Data were presented on dielectric constant and loss tangent at various frequencies. The effects of excess BaO on dielectric properties were investigated. The additions of $Na_2O$ and $Nb_2O_5$ shifted the Curite temperature of these glass-ceramics. The glass composition which was able to be melted at 145$0^{\circ}C$ and moulded as homogeneous glass phase without devitrification should contain $Al_2O_3$.$2SiO_2$ more than 30 mole %. The more the amount of additive BaO increased, the more dielectric constant increased. When the maximum heat-treatment temperature was 105$0^{\circ}C$, we obtained higher dielectric constant than that of 95$0^{\circ}C$. The dielectric constant and the dielectric loss were stable at frequencies between 5$\times$104 and 107 cycle per second. When $Na_2O$ and $Nb_2O_5$ were added, the Curie temperature, presented at 14$0^{\circ}C$ to 15$0^{\circ}C$, shifted to lower temperature. Therefore, the glass-ceramics having high dielectric constant at room temperature were obtained.

We examined the prevalence of sarcopenia and age-related changes in body composition in Korean older persons. Community dwelling 77 men and 65 women($60{\sim}88\;yr$) were recruited for this study. Fat-free mass and the percent body fat were determined using bioelectrical impedance analysis. Isometric grip strength was measurement using grip strength dynamometer. Serum levels of fasting glucose, total cholesterol, HDL-cholesterol, and triglyceride were assayed. The prevalence of sarcopenia was found to increase with aging (men in their sixties 82.6%, seventies 96.6% and eighties 100%, and women in their sixties 47.4%, seventies 63%). In both gender groups, handgrip strength was inversely correlated with age and positively correlated with height, lean mass, and fat free mass. Better handgrip strength was related with higher weight in the men and with lower heart rate in the women. Fat free mass, age, and gender were found to be independent factors significantly associated with handgrip strength in the multivariate analysis. In summary, results of the present study suggest that handgrip strength is well associated with age, gender, and fat free mass and the prevalence of sarcopenia is increased with age and is exceeded by 40% among Korean persons older than 60 years.

This study was performed to investigate the effect of different levels of dietary crude protein (CP) on composition of odorous compounds and bacterial communities in pig manure. A total of 48 male pigs (average initial body weight 45 kg) fed diets containing three levels of dietary CP (20%, 17.5%, and 15%) and their slurry samples were collected from the pits under the floor every week for one month. Changes in composition of odorous compounds and bacterial communities were analyzed by gas chromatography and 454 FLX titanium pyrosequencing systems, respectively. Levels of phenols, indoles, short chain fatty acid and branched chain fatty acid were lowest (p<0.05) in CP 15% group among three CP levels. Relative abundance of Bacteroidetes phylum and bacterial genera including Leuconostoc, Bacillus, Atopostipes, Peptonphilus, Ruminococcaceae_uc, Bacteroides, and Pseudomonas was lower (p<0.05) in CP 15% than in CP 20% group. There was a positive correlation (p<0.05) between odorous compounds and bacterial genera: phenol, indole, iso-butyric acid, and iso-valeric acid with Atopostipes, p-cresol and skatole with Bacteroides, acetic acid and butyric acid with AM982595_g of Porphyromonadaceae family, and propionic acid with Tissierella. Taken together, administration of 15% CP showed less production of odorous compounds than 20% CP group and this result might be associated with the changes in bacterial communities especially whose roles in protein metabolism.

최근 우리나라 1인가구의 비중은 점차 증가하고 있으며 이는 2035년에 들어서는 34.6%로 증가할 것이라 예측되며 이들 중, 우리나라 높은 주택가격으로 인하여 청년층 1인가구는 더 많은 어려움에 직면하고 있다. 정부에서는 청년 주거지원을 확대실시하여, 공공지원 임대주택과 민간 청년임대주택, 청년 기숙사 공급 등 다양한 정부정책을 펼쳐 나가고 있다. 본 연구의 목적은 다른 연령대와 라이프스타일이 다른 청년층 1인가구의 정확한 주거요구를 파악하여 향후 보급될 청년 주택 계획 방향을 위한 기초자료를 제공하는 것을 목적으로 한다. 이를 위한 연구방법은 다음과 같다. 첫째, 문헌고찰을 통해 청년층 1인가구의 현황과 특성을 파악하였다. 둘째, 청년층의 라이프스타일과 주거선호 관련 선행연구 고찰을 통하여 청년층 1인가구의 주거환경 선호 및 요구에 대한 조사도구를 구성하였다. 셋째, 청년층 1인가구의 라이프스타일을 바탕으로 한 공간사용특성과 평면구성 선호 및 요구, 실내디자인 선호에 대한 설문조사를 실시하였다. 조사는 2018년 12월에서 2019년 1월 초까지 학생과 직장인을 포함한 20세에서 39세 사이의 청년층 1인 가구 150명을 대상으로 SNS를 이용한 온라인 설문조사를 실시하였다. 연구결과는 다음과 같다. (1) 공간사용특성을 살펴본 결과, 작은 면적인 청년 1인 주거에서 침실과 거실이 기본적 기능 외 다양한 생활이 이루어지는 장소로 계획시 이에 대한 추가적 고려가 필요함을 파악하였다. (2) 평면구성 선호 및 요구를 살펴본 결과, 별도의 침실과 거실 공간 확보를 요구하며, 다양한 활동이 이루어지는 거실공간에 대한 확장요구와 침실공간의 드레스룸 등의 수납 추가 요구가 있음을 알 수 있었다. (3) 실내디자인 선호를 살펴본 결과, 모던스타일과 대표적 컬러인 무채색계열 색채를 선호함을 알 수 있었다. 그리고 주거공간에 일반적으로 사용되는 마감재료를 선호하며, 조명은 간접조명 및 벽면을 이용한 은은한 조명을 선호함을 알 수 있었다. 또한 청년층 내에서도 라이프스타일 특성에 따른 학생과 직장인의 차별적 실내디자인 선호 특성을 살펴볼 수 있었다. 향후 실제 공공임대주택의 사례분석과 사용자 범위확대를 통하여 실질적인 주거환경니즈와 계획방안 제안을 위한 연구가 필요하다.

The purpose of this study is to analyze characteristics of residential architecture designed by Gwathmey Siegel in terms of their way of composing spaces and forms. Charles Gwathmey, one of the founders of Gwathmey Siegel, is a worldly famous architect who actively developed Neo-Modernistic architecture in his career. For this study, 15 major houses designed by Gwathmey Siegel were selected and analyzed in terms of their approaches on how to compose various spaces and forms, and how these approaches evolved as time passed. The analysis was mainly based on the drawings and photos of the houses published. The main characteristics found in this study can be summarized as follows: elevated LDK level, split-level composition, use of framing structure, layered space, and linear galleries as a spine of circulation with collaged volumes attached. It turned out these characteristics appeared, faded away, or evolved affecting each other. In early days, Gwathmey often elevated LDK level from ground level for providing privacy, views, and also for separating private rooms. Soon they composed spaces by splitting levels. It not only helped provide privacy where needed effectively, but made space composition more interesting. As sizes of the houses they designed grew, Gwathmey came up with the framing idea for expressing his original architectural language in larger scale. With the split-level composition, the framing method represented Gwathmey's in 70's. This framing introduced layers of interior spaces, and the layers started to break down the monumental framing into individual volumes by bringing in linear spine of circulation. These characteristics helped Gwathmey Siegel develop their own architectural language.
