The U.S.-Korea fisheries relationship was concluded on the legal basis of Korea as a distant-water fishing nation and U.S. as a coastal state, and aiming effective conservation, management and rational utilization of the marine living resources. The existing two legal problems on U.S.-Korea fisheries relationship are the pelagic driftnet fishing on the high seas and trawl fishing in the Bering Sea. The results and countermeasure discussed on the positive legal systems of both countries which simultaneously rationalize the conflicting standpoints each other are as follows : 1. For the sake of rational conservation and utilization of the high seas fishery resources, an international organization composing of all the coastal states and fishing nations concerned must be established, and it shall be shall be more desirable to manage the resources by the international joint control system than by the bilateral agreements between the countries concerned. 2. The U.S.-Korea Fisheries Agreement being based on the MFCMA was concluded by mutual understanding between both countries. Accordingly, no protest exists against legal status of the Agreement because it has acted as a customary norm in keeping fisheries relationship between both countries within the U.S. EEZ. 3. The existing fisheries legislative system of Korea is insufficient to support development of the industry satisfactorily. Therefore a special legislation, for example $\ulcorner$Distant-water Fishery Promotion Act$\lrcorner$, is required. And a perfect legal system for effective conservation and management of fishery resources must be established.

Purpose: The purpose of this study was to apply Ajzen's theory of planned behavior to identify factors that affect undergraduate women's decisions to receive human papillomavirus(HPV) vaccination. Method: The research design for this study was a descriptive survey design using convenience sampling. Data collection was done using self-report questionnaires with 254 undergraduate students in G city. Data were analyzed using percentage, mean, standard deviation, t-test, ANOVA, Mann-Whitney U test, Pearson correlation analysis and multiple regression with the SPSS Win 20.0 Program. Results: The mean score of intention to receive HPV vaccine was $3.88{\pm}1.05$ out of a possible 7. Intention to receive HPV vaccine showed a significantly positive correlation with attitudes (r=.26, p<.001), subjective norm (r=.51, p<.001), perceived behavior control (r=.41, p<.001) to receive HPV vaccination. In the multiple regression analysis, subjective norm and perceived behavior control to receive HPV vaccine were significant predictors and explained 33.7% of intention to receive HPV vaccine. Conclusion: Results of this study show that there are significant factors affecting the intention of undergraduate women to receive HPV vaccination. Also, strategies emphasizing subjective norm and perceived behavior control in obtaining HPV vaccination should be taken into account in developing educational programs.

Purpose: This study was conducted using the theory of planned behavior to analyze factors influencing mothers' intention to vaccinate their children against hepatitis A (HA). Methods: This descriptive study used a questionnaire. The participants were 100 mothers with children under 19 years. The collected data were analyzed by the t-test, analysis of variance, and the Mann-Whitney U test. The Pearson's correlation was used to test the correlations among variables. Stepwise multiple regression was used to identify factors related to HA vaccination intention. Results: The attitude of mothers with children under 19 to HA vaccination were quite positive (6.2 of 7), and their perceived behavioral control (5.73 of 7), subjective norm (5.54 of 7), and vaccination intention (5.96 of 7) were relatively high. Attitude toward HA vaccination was the strongest influencing factor, followed by subjective norm. The explanatory power of attitude and subjective norm for HA vaccination was 84%. Conclusion: HA vaccination is very important for preventing HA. Mothers' positive attitudes toward HA vaccination were an important factor influencing their children's HA vaccination. Providing education on the benefits of HA vaccination and the vaccination schedule may foster positive attitude toward vaccination.

Let A be a $JB^*$-triple with Banach dual space $A^*$ and bi-dual the $JBW^*$-triple $A^{**}$. Elements x of $A^*$ of norm one may be regarded as normalised 'Q-measures' defined on the complete ortho-lattice ${\tilde{\mathcal{U}}}(A^{**})$ of tripotents in $A^{**}$. A Q-measure x possesses a support e(x) in ${\tilde{\mathcal{U}}}(A^{**})$ and a compact support $e_c(x)$ in the complete atomic lattice ${\tilde{\mathcal{U}}}_c(A)$ of elements of ${\tilde{\mathcal{U}}}(A^{**})$ compact relative to A. Necessary and sufficient conditions for an element v of ${\tilde{\mathcal{U}}}_c(A)$ to be a compact support tripotent $e_c(x)$ are given, one of which is related to the Q-covering numbers of v by families of elements of ${\tilde{\mathcal{U}}}_c(A)$.

Top soil samples across the state of Kuwait numering ninety were collected and analysed using gamma-ray spectrometry, to evaluate the elemental concentration of $^{238}U$, $^{232}Th$ and $^{40}K$ and their depletion/enrichment. Results of elemental concentration ranges from 0.48 to 2.61 mg/kg, 0.87-5.23 mg/kg, and 0.24-2.23%, with a mean values of 1.39 mg/kg, 3.47 mg/kg, and 1.18%, for the $^{238}U$, $^{232}Th$ and $^{40}K$, respectively. Further analysis was conducted amongst the five identified soil types, i.e. Aquisalids (S1), Calcigypsids (S2), Petrocalcids (S3), Petrogypsids (S4), and torripsamment (S5). The highest radioactivity concentrations from both uranium and thorium were recorded in the S2 (Calcigypsids) soil, with a value of 1.71 (mg/kg) and 4.45 (mg/kg), respectively. Minimum and maximum values of $^{40}K$ are 1.1(%) and 1.27(%) and is prevalent in Aquisalids (S1) and Petrocalcids (S3) soil types, respectively. Ratios of elemental concentration for $^{232}Th/^{238}U$, $^{40}K/^{238}U$, $^{40}K/^{232}Th$ across the soil types are 2.53, 0.09 and 0.03, with a correlation coefficient of 0.92, 0.34, and 0.38, respectively. A progressively higher $^{232}Th/^{238}U$ ratio is observed moving south-wards, indicating lower $^{238}U$ content in soils from the south relative to the northern part. Overall results indicate Kuwait to be relatively an area with low level of natural radioactivity.

We consider a linear differential game described by the delay-differential equation in a Hilbert space H; (※Equations, See Full-text) U and V are Hilbert spaces, and B(t) and C(t) are families of bounded operators on U and V to H, respectively. A(sub)0 generates an analytic semigroup T(t) = e(sup)tA(sub)0 in H. The control variables g, and u and v are supposed to be restricted in the norm bounded sets (※Equations, See Full-text). For given x(sup)0 ∈ H and a given time t > 0, we study $\xi$-approximate controllability to determine x($.$) for a given g and v($.$) such that the corresponding solution x(t) satisfies ∥x(t) - x(sup)0∥ $\leq$ $\xi$($\xi$ > 0 : a given error).

In the present paper, we utilize the notion of converse commuting mappings due to L$\ddot{u}$ [On common fixed points for converse commuting self-maps on a metric spaces, Acta. Anal. Funct. Appl. 4(3) (2002), 226-228] and prove a common fixed point theorem in Menger space using an implicit relation. We also give an illustrative example to support our main result.

A greater number of persons with disabilities including an increasing number of aging population has brought concerns on diversity and equality in use of products and environments. Universal design concepts have been introduced rapidly and widely in the built environments in Korea. The purpose of this study was to analyze a model house built in 2006, in the U.S. as a universal design home, systematically examine the universal design model house features, and explore possibility of application of the universal design features in the U.S. into a Korean setting. For this study, site analysis and contents analysis methods were used. Although housing norm, behavioral patterns and environmental contexts would be different, majority of universal design features appeared in the model house were expected to apply. Overall universal design features in the model house sought for attractive, comfort, convenient and safe environment with a little cost. Universal design features in the model house appeared in unobtrusive ways. Universal design considerations on floor materials in living room and bath and furniture arrangement need to modify or replace according to Korean lifestyle.

Some industrial minerals used in domestic industries such as monazite, apatite, bauxite, and ilmenite belong to NORM (Naturally Occurring Radioactive Materials) because they show a high radioactivity. Products, semi-products, wastes, and by-products which show higher radioactivity than NORM belong to TENORM (Technologically Enhanced Naturally Occurring Radioactive Materials). Apatite used for manufacturing phosphate fertilizer in Namhae Chemical company belongs to NORM, and its by-product, phospo-gypsum, belongs to TENORM. A geological investigation is needed for the future environmental impact assessment of the Namhae Chemical company's site. According to survey results of the Namhae Chemical company's site, soil mineral composition indicated the mixture of minerals derived from the country rock (quartz, feldspar, mica, $l4{\AA}$ mineral, kaolin and amphibole) and minerals from the gypsum open-air storage yard (gypsum and apatite). Soil samples showed average content of U 4.6 ppm and Th 10 ppm, which are similar to average crustal abundances. They also show average contents of $^{40}K$ 191-1,166 Bq/kg, $^{226}Ra$ 15.6-710 Bq/kg, and $^{232}Th$ 17.4-72.7 Bq/kg, which indicate moderate levels of radio nuclide. But $^{226}Ra$ anomaly in the gypsum open storage yard is clearly confirmed and $^{232}Th$ anomaly is also confirmed in the east road side of the factory and nearby mountain areas. Soil external hazard indices ranged 0.24-2.01 with the average 0.54. Although most external hazard indices were lower than 1, which means radiation hazard index to be negligible, 5 samples out of total 40 samples showed higher values than 1, and further detailed investigation is needed.
