  • The purpose of this study was to investigate the effects of the low level irradiation on the mitotic index of the basal cells in the buccal pouch of hamsters{golden hamster: APG strain). After colchicine was administrated to the hamsters through the intraperitoneal, the low level radiation{5460mR) was exposed on the buccal pouch of hamsters. The mitotic index of the basal cells was estimated 2 hours after irradiation. The results were as follows: 1. The mean mitotic index of the control group was 4.32. 2. The mean mitotic index of the irradiated group was 2.46. 3. T-test of data in the irradiated group showed significant difference from the mitotic index in the control group. These results suggested the lowered mitotic index of the irradiated group resulted from the low level irradiation.

  • In order to ensure building energy management at an appropriate level continuously, it is necessary to define clearly service work of energy management and to suggest evaluation index whether energy management in buildings is fit and improvement is needed or not. But, evaluation index of energy management level in buildings is not suggested yet in Korea. So, the purpose of this paper is to suggest evaluation index of energy management level in buildings, investigate the present state of Korean buildings and evaluate energy management levels. As a result of surveys of evaluation index of energy management, it is found that portion of level 1, which is the best level, is higher than any other level, level 2, level 3. And, throughout analysis, it is found that as total floor area is larger, evaluation index of energy management level is better, and, in order to increase energy management level, first of all, there is necessary for building's users to change understanding about energy saving and make a reform of national policy of energy management in buildings. Because there is rich relationship between items among evaluation index of this stuff and result value of evaluation index, evaluation index of energy management suggested in this study is available to evaluate energy management level in buildings.

  • The purpose of this study was to assess healthy city level of the selected cities of Korea, Japan, and England using healthy city index. Based on WHO health city profile, this study proposed 5 index domains comprised with human biology, life style, shelthe & socioeconomic data, environmental & infrastructural data, and public health policy and services. We identified 6 cities (Changwon, Wonju, Seoul, Ichikawa, Fukuroi and Brighton). The human biology level of Korean cities was better than that of Ichikawa, Fukuroi, and Brighton city except Wonju. But the shelter & socioeconomic index level of the foreign cities was better than that of Korean cities. In the environmental & infrastructural idex, even though Changwon city showed the highest level among healthy cities in this study, other Korean cities had lower level compared to the foreign cities. In the public health policy and services index level, except Wonju, Korean cities had lower level than that of all foreign cities. In comparing a summative evaluation index of all proposed index, Ichikawa and Fukuroi had the highest level of city health but Seoul city had the lowest healthy level. Changwon and Wonju had higher level of city health compare to that of Brighton and Seoul. To promote the level of city health, those findings could contribute to healthy city planning process in terms of identifying any weakness and strength of the cities selected in this study.

  • In this study, we individualize the clauses to sort out the troubled ones, draw up a interrelation model in order to visually organize the relations, and finally, suggest the desirable application idea. The interrelation model suggested in this study has been made based on the matrix method. On this matrix, we arranged the environmental factors on horizontal and vertical axis, and when we describe the relation of each factors, we set the horizontal axis as the base and divided the content into three grades : Fine, Medium, and Poor. In addition to that, we expressed those three grades into numerical value like 3 points for Level Fine, 2 points for Level Medium, and 1 point for Level Poor and then, we converted this numerical values into index numbers. We could classify the index numbers such as AS, PS, Q-index, P-index. AS is an index numerically shows the degree of giving environmental effect, PS is an index numerically shows the degree of receiving environmental effect, Q-index is an index shows the aggravate degree, and P-index shows the relation degree. The Q/P-index with large numbers has considerable effect on the environmental system, while the small numbered Q/P-index barely effect on the environmental system. Moreover, we classified the environmental factors into 5 levels(I~V) according to the relations between the Q-index and P-index. Level I is less affected by the environment and has more giving effect, while Level V is more sensitively affected by the environment and has more receiving effect, which we considered important. Therefore, we could come up with the result that if we consider the each level of factors when we evaluate the EIA, the result would be far more accurate and reliable since it contains mutual relation aspect of EIA. The suggested interrelation model in this thesis is presentable as one of those scoping system. We highly believe the need of scoping system in EIA and suggest the interrelation model as the alternative idea for scoping system.

  • Due to the dramatic increase in consumers' price sensitivity and growing importance for global retailers to create relevant price strategies, this study investigates the global pricing strategy of the main SPA brands such as ZARA, H&M and UNIQLO. Based on price information shown on official website, the study developed SPA brand index by using exchange rates in terms of US dollars and ratio of differences between the local price and the US price. These figures were compared with GDP per person data in order to analyze each brand's price level against the income level. The study also compared SPA brand index with Big Mac index to identify the difference in price levels between the fast fashion market and the fast food market. ZARA and H&M were mostly targeting Middle East and Asia as a high-price market when considering index only. After taking the income level into account, however, Asia came out be the highest price market and Middle East was similar to the US market. On the other hand, UNIQLO targeted Asia as the lowest price market and the US and EU as the highest in terms of index only. But, Asia came out to be the highest price zone after considering the income level while the price of the US and EU was reasonable. Comparison with Big Mac Index indicated that most of Asia had a higher price level of the fashion market than the food market, whereas most European countries had a similar or high-price level of food market.

  • The genus-level biotic index of benthic macroinvertebrates (Benthic Macroinvertebrates Genus Index, BMGI) was developed and applicated based on the data collected from 13,347 sampling units of 814 sites from 2010 to 2021 in Korea. Tolerant values of 274 indicator taxa were established by analyzing the relationship between the relative frequency and abundance of indicator taxa and the water quality index considering biochemical oxygen demand (BOD5), total suspended solids (TSS), and total phosphorus (T-P). BMGI showed a slightly higher correlation with water quality than the species-level biotic index (Benthic Macroinvertebrates Index, BMI) that was developed and applied in Korea. Although the BMGI does not contain species-level information, the reason why BMGI shows higher applicability than BMI seems to be due to the increase in the number of indicator taxa and the decrease in the misidentification of immature aquatic insects. The coefficient of determination in multiple regression with BOD5, TSS, and TP for BMGI was 0.62 in the long-term averaged data of 814 sites, and the standardized coefficient of BOD5 was -0.46, TSS was -0.17 and T-P was -0.21, respectively. As a result of the evaluation by BMGI, of the 814 sites, 38% were in good, 25% in fair, and 37% in poor condition.
