To compare the water vapor transmission rate (WVTR) of PVA/Dextran blended hydrogel obtained by European Pharmacopiea (EP) and Japanese Industrial Standards 1099 (JIS) method, the hydrogels with various PVA/Dextran rates were prepared and their WVTR values were then checked. As dextran in the hydrogel was increased, the WVTR of hydrogel was increased. The WVTR of hydrogels were 660-1500 and $730-1900\;g/m^2$-day in EP and JIS method, respectively. There were no significant differences between the WVTRs of the hydrogels obtained by EP and those obtained by JIS method. Thus, JIS method was recommended as a WVTR method of hydrogel due to relatively simpler and shorter time.

In this study, the effects of chitosan pre-treatment on the mordanting effect and dyeability were investigated in the dyeing using Japanese pagoda tree. The chitosan treatment effects were evaluated mainly focused on the colors after dyeing of cotton and nylon fabrics which were treated with acidic aqueous solution of chitosan. In the case of chitosan untreated fabrics, the mordanting effects on the cotton and nylon were insignificant and the dyeability was very low. Regardless of the mordant types(Al, Sn, and Fe), the dyed fabrics exhibited almost identical yellowish colors. In the case of chitosan treated fabrics, dark colors were obtained compared to the case of chitosan untreated and ${\Delta}E$ values were increased significantly. In cotton fabrics, the most excellent result was obtained under the condition of unmordanted and chitosan treated fabrics. This verifies the fact that routin coloring matters establish direct linkages with the chitosan components, which exhibit cationic nature, easily. In nylon fabrics, the effects of mordanting treatment and chitosan treatment are so insignificant that the routin coloring matters are presumed to establish direct dyeing with the nylon molecular chains.

In this study, an externally reinforced structural system for SMC(Sheet Molding Compound) panel water tank, designed according to the Japanese design code, is experimented to evaluate its seismic performance. The test tank is 3m long, 2m wide and 3m high, considering the capacity and size of the shaking table. The measured hydrodynamic pressures are found to be approximately 70% of the Japanese design code values. It may be partially due to the convex shape effect of the unit panels. The analytical results of externally reinforced system based on the measured dynamic water pressures are found in good agreement with the test results. If the design hydrodynamic pressures are estimated properly, the proposed analytical model for the externally reinforced water tank becomes a useful design tool and the Japanese design code is found to provide a safe design for the external frames of SMC panel water tank.

Rice farming is not only the most important income resources of Korean farmers but also the roots of Korean traditional culture. Paddy fields have acted as an food supply base but also have contributed to the public multi-functions such as flood control, water conservation, controlling soil erosion, providing recreational and resting spaces, water purification, air cleaning, oxygen supply and air cooling and so on. The public multi-functions of paddy except rice production have not been evaluated before UR negotiation and starting WTO system. Under the drastic changes of rice economic settings as price decrease of rice and downward decrease of farm income, Korean and Japanese farmers might have lost their intention to grow rice in paddy fields without the direct payment system to compensate rice income decrease. To adapt the direct payment system, the total public value of multi-function of paddy should be identified in terms of money. According to the research results, the total value of multi-functional value of paddy in Korea were estimated 21,596thousand won which is higher than rice production value by 2.1 times. On the other hand the total value of Japanese paddy were amounted to 21,390 Yen which is more than that of Korea by 10times outstandingly. Likewise Japanese have evaluated the paddy field very important enterprise from the view point of food security and multi -functions of paddy to their socio-economic life and environmental sustainability in Japan.

The early studies on the cultural industries had mainly emphasized the viewpoint of "efficiency" based on the "flexible specialization" theory, but they have gradually shed light on the viewpoint of "creativity": creative human resources and various networks generating creative energies. Despite the importance of these studies, it is impossible to explain every cultural industrial agglomeration phenomena from specific and few viewpoints due to the diversity of each cultural industry. This study describes the dissimilarity of agglomeration factors between the Japanese animation and home video game industries which form salient agglomeration in the same region. Both industries share similar characteristics with industrial agglomeration of SMEs in Tokyo and close inter-firm relationships. However, they differ in their historical development paths and each firm's behavior and strategy because of their own distribution systems and production processes. In particular, the difference in distribution systems clearly affects whether a company values "efficiency" factors of agglomeration advantage or "creativity" factors of that in case of locational choice. The distribution sector of the cultural industry, compared with the production sector, has a tendency to value profitability rather than creation itself. Therefore, a cultural industry with the strong distribution sector tends to form the industrial system emphasizing profitability. The Japanese animation firm is apt to choose its location from the perspective of efficiency, which easily contributes to profitability, because television broadcasting stations are strong distribution sector. Conversely, the Japanese game firm chooses its location from the perspective of creativity due to the absence of strong distribution sector.

In the Japanese garden, a unique planting design has been used to improve visual harmony with the surrounding landscape by planting plants around the objects that are not harmonious with surrounding landscape. In this study, physiopsychological effects of plants caused by a traditional planting skill used in Japanese garden was verified in terms of visual relaxation using eye movement recording and semantic differential method. A total of fourteen Japanese volunteers(seven male and seven female) who have normal vision(aged $21{\sim}28$) participated as subjects. Experiment was carried out in the sealed room of Chiba University in Japan. Four different types of scenery models were presented which were created by combination of the three landscape factors of the surrounding background, the object that disturbs visual harmony, and the trees planted for improving visual harmony with the surrounding landscape. In the results, significantly more gaze fixations were measured on the trees than on the object and higher values in positive feelings were recorded for the stimuli with proper planting combination. Our results indicated that proper tree planting can cause physiopsychological relaxation by improving visual harmony with the surrounding landscape and provided new evidence for supporting scientific validity of the traditional planting skills.

The study confirmed the "house search report(家宅搜索調書)" containing criminal records during the Japanese colonial period, as well as the production process and the way of expressing the illustrations contained in them. It also explored architectural values through analysis of the location and use of the building. This records the discovery of evidence by searching the residences of those involved in the crime from 1919 to 1922. The illustrations contained in this record were not standardized, so the contents of the article differed depending on the author's background and cultural experience. Nevertheless, this painting reflects the regional characteristics of traditional houses located throughout the Korean Peninsula. It is also evidence that the house was used for cultural, commercial, and industrial purposes, beyond the general assumption that it was used only for residential purposes. The "House Search Report(家宅搜索調書)" provides information on ordinary buildings that existed as the background of everyday life, rather than buildings with a specific purpose or exceptional design. It is evaluated as an important resource for understanding the diverse life and spatial structures of buildings during that time.

The objectives of this study were to estimate genetic parameters and sire breeding values for average daily gain (ADG) and carcass traits using sire-maternal grandsire model with REML approach, sire model with REML approach, sire model without relationships among sires and with REML and ANOVA approach, and to investigate advantages and disadvantages of these methods. Data were collected from 42,325 Japanese Black steers and heifers finished and slaughtered from 1991 to 2004. Traits analyzed in this study were average daily gain (ADG) during the fattening period, live weight at slaughter (LW), cold carcass weight (CW), estimated lean yield percentage (LYE), longissimus muscle area (LMA), subcutaneous fat thickness (SFT), rib thickness (RT), and marbling score (BMS). Bivariate analyses were also performed to obtain genetic and phenotypic correlation coefficients among traits. Estimated breeding values were obtained from each model, and simple and rank correlations among breeding values from each model were calculated. Estimates of heritability using the four models ranged from 0.25 to 0.31 in ADG, from 0.21 to 0.24 in LW, from 0.23 to 0.27 in CW, from 0.10 to 0.17 in DP, from 0.40 to 0.42 in LYE, from 0.19 to 0.31 in LMA, from 0.31 to 0.34 in SFT, from 0.26 to 0.33 in RT, and from 0.18 to 0.44 in BMS. The differences in heritability estimates using the four models seemed to be feasible in ADG, CW, DP, LMA, RT, and BMS. Genetic correlation coefficients of ADG with CW, SFT, RT and BMS were moderate to high and positive while the genetic correlation coefficients between ADG and LYE was low and negative. Correlation coefficients of BMS with SFT were negligible for both genetic and phenotypic correlations. The correlations of estimates evaluated from sire models with those from sire-maternal grandsire model were not large enough to convincing that breeding values using a sire model were corresponding to those using a sire-maternal grand sire model. If information of maternal grand sires are not available, the sire model with incomplete pedigree information included only sire of sire (Model 2) is optimal among the sire models evaluated in this study.

Huam-dong is a representative area from the Japanese colonial period and is the space where most Japanese-style buildings remain in Seoul. Interest in modern cultural heritage continues to increase, including the registration of cultural properties in 2001, building assets in 2015, and the registration of cultural property units in 2018. As the debate continues over the necessity of preserving cultural heritage that reminds us of the Japanese colonial, there is a need for research to grasp the perceptions of stakeholders along with the perceived value of such spaces. This study identified the subjective perception types of the stakeholders concerned with the Japanese-style building group in Huam-dong, analyzed characteristics by types, and debated the issues. For this purpose, Q methodology, which is a statistical technique for measuring human self-subjectivity and extracting common human perspectives, was used. A literature study on the values of Huam-dong and modern cultural heritage was conducted, and a Q questionnaire based on five aspects of modern cultural heritage values (historical, architectural, sociocultural, landscape, and economic) was applied. The results of the study depicted three types of cognition and showed different attitudes toward the Japanese building group. This study found a conflict comparing the perceptional differences between the types of cognition. This study is meaningful in that it provides an in-depth approach to the perspectives of the stakeholders concerned with the Japanese-style buildings clustered in central Seoul. It is also meant to present a theoretical framework that can be applied to the use area as sustainable cultural heritage through the establishment of preservation and utilization of Japanese-style areas and conflict resolution.

The quality of brown rice vinegar that was produced via static culture (A) was compared with the quality of three types of domestic commercial brown rice vinegar (B, C, and D) and of three types of Japanese brown rice vinegar (E, F, and G). The results showed titratable acidity levels of 6.39%, 4.52-6.32%, and 4.51-4.89% in the static-cultured brown rice vinegar, the domestic commercial brown rice vinegars, and the Japanese brown rice vinegars, respectively. The pH levels were 3.28, 2.58-2.97, and 3.03-3.27 in the static-culture brown rice vinegar, the domestic commercial brown rice vinegars, and the Japanese brown rice vinegars, respectively, which show similar values of the static-culture brown rice vinegar and the Japanese brown rice vinegars. The total nitrogen (TN) values of the static-culture brown rice vinegar, the domestic commercial brown rice vinegars, and the Japanese brown rice vinegars were 0.24, 0.03-0.16, and 0.12-0.17, respectively, with the highest value for the static-culture brown rice vinegar, substantial differences among the domestic commercial brown rice vinegars, and similar contents among the Japanese brown rice vinegars. For free sugar, glucose was either detected only in a small quantity or not detected at all in the static-culture brown rice vinegar and the Japanese brown rice vinegars, which showed perfect fermentation. The glucose and maltose contents were higher in the domestic commercial brown rice vinegars. The organic acid content of the static-culture brown rice vinegar was similar to that of the Japanese brown rice vinegars. Therefore, the total acidity content, TN value, sensory property, and quality of the static-culture brown rice vinegar (A) were superior to those of the domestic and Japanese brown rice vinegars.
