  • This study was carried out to scrutinize possibility of manufacturing pitch pine (Pinus rigida) glued laminated timber in order to add values of pitch pine trees. Also, it was investigated to improve bending performance of pitch pine glulam. Pitch pine was imported as one of major plantation species in Korean peninsula. Machine stress rated grades of pitch pine lumber mostly ranged between E7 and E9. which grades were more or less inferior to producing high quality glulam. However, the adhesive properties between pitch pine and pitch pine, and between pitch pine and Japanese larch (Larix kaempferi Carr.), such as shear bond strength, wood failure rate and de-lamination rate of bonded layer submerged in cold and boiling water, were higher than Korean Standard criteria. These properties are essential for manufacturing glulam with single species or multiple species. The modulus of rupture (MOR) of pitch pine glulam exceeded the criterion of Korean Standard for glulam strength grade but modulus of elasticity (MOE) was lower than the criterion. On the other hand, the bending performances (MOR and MOE) were improved 20 percent by mixing with Japanese larch laminar. It is effective to arrange higher quality Japanese larch laminar at the outer layer of glulam for improving bending performances. In conclusion, it is possible to use low quality pitch pine as laminar of structural glulam for adding values of pitch pine.

  • Fruit leathers were manufactured from flesh and pomace of Japanese apricots and evaluated for their physical, chemical, microbiological and sensory properties. The contents of total dietary fiber(TDF) in Japanese apricot leathers(JAL) and Japanese apricot pomace leathers(JAPL) were 4.06% and 7.82%, respectively. One hundred grams of leather contained 368kcal in JAL and 352kcal in JAPL. Water activities of fruit leathers were 0.36 in JAL and 0.48 in JAPL. None of the factors had an effect on the microbiological counts of any of the organisms. The L, a and b values of the fruit leathers were higher in those made of JAF than those made of JAP. The fruit leathers made of JAF were harder than those made of JAP. Sensory panelists preferred fruit leathers made of JAP to those made of JAF in all attributes, except for their color.

  • Objectives: This study analyzed Japanese consumers on their sauce consumption, and assessed the relationship between consumer innovativeness and consumption behavior for new sauce products. Methods: The survey was completed by local consumers visiting Korean restaurants in Osaka, Japan, in September 2018. The demographic characteristics, consumption of sauce, consumer innovativeness, and factors of theory of planned behavior were evaluated. Totally, 150 collected data were analyzed using the IBM SPSS Statistics 25.0 Program (IBM SPSS INC, Armonk, NY, USA). Results: Results of the survey indicate that Japanese consumers purchase a sauce by considering the taste and food utilization. Sauce purchases were maximum at mega markets and supermarkets. The consumer innovativeness for Japanese consumers was based on 3 factors: 'Purchasing adventurous products (3.51 ± 0.96)', 'Active information seeking (4.36 ± 1.11)', and 'Interactive information seeking (4.33 ± 1.02)', where the tendency of 'Active information seeking' was the highest innovativeness factor. Furthermore, higher values of perceived behavior control (4.68 ± 1.21), attitude (4.66 ± 1.41) and subjective norm (4.39 ± 1.28) were revealed, when assessing for theory of planned behavior factors. Correlating the variables of consumer innovation and factors of planning behavior theory, 'Active information seeking' is a positive attribute for attitude (p<0.016), subjective norm (p<0.001), and perceived behavior control (p<0.002). These 3 factors also had significantly positive effects on purchase intention for new sauce product (p<0.000, p<0.000, and p<0.002, respectively). Attitude was determined to be another very influential variable for purchase intention of a new sauce product (B=0.484, t=6.881). Conclusions: The results of this study determine the consumption patterns of sauce for the Japanese consumer, and the relationship between consumer innovativeness and consumption behavior for Korean traditional sauces. We believe the data generated from this study will help determine a marketing strategy to enter the Japanese market.

  • In geodesy, a calculation of the meridian length is a basic thing. Its principle is very simple, but no exact closed formula exists and its expression has rather long terms. In Korea, the formula has been seemingly adapted from those of Japan which also use the Bessel ellipsoid as a reference. However, a formula from a noticeable reference of Japan is found to have wrong coefficient values. In this study, a formula for the meridian length with correct coefficient values is suggested and the results on different computing bases are also shown. This formula has terms simpler than the one in the Korean Surveying Act (Law) which has the same coefficients in that Japanese reference.

  • This study is to analyze the affecting factors to the peak factor in the drinking water supply Facilities. The peak factor is a very important element to determine the capacity of the water supply facllities. Several factors such as Population served, average day water demand, ratio of domestic water use, ratio of affairs & business water use and water use per capital per day were selected as the affecting factors in this study. In this study, peak factor characteristics for Korean facilities were compared with those for Japanese ones. As a result, non-exceedance probability was suggested as the designing method for the peak factor. Also, the 50% non-exceedance probability values and the 90% values based on the 1998-1999 data were suggested in this study.

  • An Asian Ethnic Look is based on its own values of traditional costumes and the fashion accessories that are influenced by its own genre within their own culture. In this thesis, it contemplates the study of visual values and the traditional influences of the Modern Western Designers and Asian Designers' definitions and the considerations of an Ethnic look in the countries like Middle East, India, Korea, China and Japan. The standard procedure to understand their Visual and Aesthetic values is acknowledgement of body. From that foundation, an Asian Ethnic Look and its Visual and Aesthetic Values were researched through out the Middle East Asian Look, Indian Look, Korean Look, Chinese Look and Japanese Look which effective after 1990's. The studies are further researched to the comparisons and interpretations of the Western Designers and the Asian Designers, and the definitions of an Asian Ethnic Look and its Visual and Aesthetic Values in between those. According to each country's religious attitudes, a beauty of concealment and a beauty of negative space appeal which emphasize an ethics on humanity and non-materialistic attitudes. It takes meanings of a phenomenon of nature's worship, Yin-Yang five elements of principles, oneness of body-mind and oneness of universe-mankind. Following the studies of Visual and Aesthetic Values of an Asian Ethnic Look, in 1990's Western Designers' interpretations were prominent use of the Asian Traditional Motif3. However, the interpretations of the Asian Designers were based on their own traditional ethics and they minimized decorative elements but enhanced naturalism, feminism, calm and sober designs compare to the past. The Asian Designers' interpretations of their visual values were based on their Asian mentality, beauty and its straightforward genuine perspective and respects of their own culture.

  • This study was conducted to examine the relationships between the methods used to determine the number of transferable embryos collected per flush and the estimated cumulative genetic improvements in the Japanese Holstein MOET breeding population. Cumulative genetic improvements were predicted by Monte Carlo simulation using three different determination methods (MODEL 1, MODEL 2, and MODEL 3), for calculating the number of embryos collected per flush. Moreover EBVs were estimated including or ignoring coefficients of inbreeding in MME. Inbreeding coefficients were also predicted. The number of transferable embryos was determined using normal, gamma, and Poisson distributions in MODEL 1, gamma and Poisson distributions in MODEL 2, and only the Poisson distribution in MODEL 3. The fitness of MODEL 2 in relation to field data from Hokkaido Japan was the best, and the results for MODEL3 indicated that this model is unsuitable for determining the number of transferable embryos. The largest cumulative genetic improvement (3.11) in the 10th generation was predicted by MODEL 3 and the smallest (2.83) by MODEL 2. Mean coefficients of correlation between the true and estimated breeding values were 0.738, 0.729, and 0.773 in MODELS 1, 2, and 3, respectively. It is suggested that the smallest genetic improvement in MODEL 2 resulted from the smallest correlation coefficient between the true and estimated breeding values. The differences in milk, fat, and protein yields between MODELS 2 and 3 were 182.0, 7.0, and 5.6 kg, respectively, in real units when each trait was independently selected. The inbreeding coefficient was the highest (0.374) in MODEL 2 and the lowest (0.357) in MODEL 3. The effects of different methods for determining the number of transferable embryos per flush on genetic improvements and inbreeding coefficients of the simulated populations were remarkable. The effects of including coefficients of inbreeding in MME, however, were unclear.

  • The probable rainfall depth is an important hydrologic design data in establishing the hydraulic engineering project at urban watershed. This study is to unificate the probable rainfall intensity formula at Seoul. The probable rainfall intensity formula at Seoul is basically formed by the types of Talbot, Sherman and Japanese. But these formulae may be unified to uniform type. The unified probable rainfall intensity formula is more applicable than that of the existing types at Seoul. Especially on the probable rainfall depth of total duration the application of unified formula general type is better than existing types. In this formula, values of n are decreasing with return period and increasing with rainfall duration, and values of coefficient, b, are decreasing with the increase of return period. The range of n varies from 0.55 to 0.60 for short duration, from 0.60 to 0.82 for long duration, and from 0.60 to 0.66 for total duration of probable rainfall depth.

  • Background: International organizations such as the World Health Organization (WHO) and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) reported public exposure doses due to radionuclides released in the Fukushima nuclear accident a few years after the event. However, the reported doses were generally overestimated due to conservative assumptions such as a longer stay in deliberate areas designated for evacuation than the actual stay. After these reports had been published, more realistic dose values were reported by Japanese scientists. Materials and Methods: The present paper reviews those reports, including the most recently published articles; and summarizes estimated effective doses (external and internal) and issues related to their estimation. Results and Discussion: External dose estimation can be categorized as taking two approaches-estimation from ambient dose rate and peoples' behavior patterns-and measurements using personal dosimeters. The former approach was useful for estimating external doses in an early stage after the accident. The first 4-month doses were less than 2 mSv for most (94%) study subjects. Later on, individual doses came to be monitored by personal dosimeter measurements. On the basis of these measurements, the estimated median annual external dose was reported to be < 1 mSv in 2011 for 22 municipalities of Fukushima Prefecture. Internal dose estimation also can be categorized as taking two approaches: estimation from whole-body counting and estimation from monitoring of environmental samples such as radioactivity concentrations in food and drinking water. According to results by the former approach, committed effective dose due to 134Cs and 137Cs could be less than 0.1 mSv for most residents including those from evacuated areas. Conclusion: Realistic doses estimated by Japanese scientists indicated that the doses reported by WHO and UNSCEAR were generally overestimated. Average values for the first-year effective doses for residents in two affected areas (Namie Town and Iitate Village) were not likely to reach 10 mSv, the lower end of the doses estimated by WHO.
