To determine the salinity of packaged Kimchi, bulk Kimchi and other common foods, we collected samples of foods from the Gyeonggi province area in October 2006 and determined the salinity levels in one serving portion. The average salinity of all foods was 0.226${\pm}$0.212%. The average salinity of all Kimchi samples was 0.401${\pm}$0.260. The average salinities of soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.153${\pm}$0.085%, 0.691${\pm}$0.213%, 0.151${\pm}$0.102%, 0.209${\pm}$0.121% and 0.080${\pm}$0.016%, respectively. The average salt intake of one serving of Kimchi was 0.125${\pm}$0.041 g, while the average salt intakes of one serving of the soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.306${\pm}$0.170 g, 1.382${\pm}$0.426 g, 0.094${\pm}$0.061 g, 0.146${\pm}$0.089 g, and 0.159${\pm}$0.152 g, respectively. The salinity of packaged Kimchi was significantly higher than the salinity of the bulk Kimchi (p < 0.01). In addition, the salinity of the liquid and solid stem portions of the packaged Kimchi was significantly higher than the salinity of the same sized portions of the bulk Kimehi (p<0.01). Furthermore, the salinity in the liquid and solid stern portions of the packaged mustard leaf Kimchi were significantly higher than the salinities of other types of Kimchi (p < 0.0001). The salinity of all Kimchi is higher than that of soup, protein containing side dishes, vegetable side dishes or drinks, but the salt content of one serving of Kimchi is lower than those of the soups or stews or vegetable side dishes or drinks (because one serving size of Kimchi is usually smaller than that of the other foods).

This study was carried out to estimate the relationship among dietary intakes, blood levels, and urinary excretions of Ca, P, Mg and serum lipid levels in 30 healthy adults living area of Korea(12males and 18 females). Analyses for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hours urine collection, and venous blood sampling before anthropometry. The mean daily intakes of Ca, P and Mg estimated for 3 days were 452.5$\pm$159.5mg, 725.6$\pm$ 567.8mg and 240.4$\pm$78.5mg and the serum concentrations of Ca, P and Mg were 8.9$\pm$ 0.5mg / dl, 3.3$\pm$0.6mg / dl, and 2.1$\pm$0.8mg /dl, respectively. The 24-hour urinary excretions of Ca, P and Mg were 80.4$\pm$24.0mg, 399.0$\pm$161.1mg and 64.8$\pm$35.3mg, respectively. The serum concentrations of total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol were 158.8$\pm$32.9mg/dl, 95.6$\pm$43.9mg/dl, 45.7$\pm$9.9mg/dl and 92.2$\pm$ 28.5mg/dl, respectively. In the relation between Ca, P, Mg and serum lipids it showed positive correlation with serum Ca and HDL-cholesterol at the level of significance of 5%. It can be concluded that the high level of Ca in serum may be useful in the prevention of cardiovascular disease, but the study verifies the need for more systematic studies.

Hepatotoxicity of caffeine and acetaminophen was investigated in this study. Special attention was paid to the effect of vitamins on the reduction of hepatotoxicity caused by the chemicals. Rat hepaocytes isolated by two-step perfusion method were cultured in two differents methods-suspension, monolayer cultures-, and exposed to caffeine and/or acetaminophen for 24hrs. Caffeine or acetaminophen exhibited no significant hepatotoxicity in terms of intracellular glutathione(GSH) level and lipid peroxidation(MDA), but GSH level was significantly decreased after administrated acetaminophen, and the toxicity caused by the chemicals showed a dose-dependent manner. The synergistic effect of caffeine and acetaminophen was observed when both caffeine and acetaminophen were supplemented to culture medium. At the concentration 1mM, caffeine enhanced the intracellular GSH depletion and MDA formation by 63% and 64%, respectively, compared to single supplementation of 10mM acetaminophen in culture medium. This hepatotoxicity induced membrane integrity loss was observed by lightmicroscope on the simultaneous administration of caffeine and acetaminophen in monolayer cultured hepatocytes. Co-supplementation of vitamins with caffeine/acetaminophen to culture medium results in the protection of hepatocytes from hepatotoxic attach by caffeine/acetaminophen. Especially, vitamin E was superior to vitamin C and $\beta$-carotene from the standpoints of GSH depletion and MDA formation. From this results, it has been speculated that vitamin E may play a role of antioxidant scavenging radicals produced from acetaminophen. Taken all together, in vitro culture system like monolayer culture of hepatocytes may be a useful tool for the evaluation of hepatotoxicity or protection ability of food ingredients.

The purpose of this study is to examine the experience of case management practice for residents of low - income housing. The importance of the house for the vulnerable residents with homelessness is absolute, and case management that supports them to live as residents in the community is also very important. Nevertheless, the research so far has focused on the supply of affordable housing, the residential environment, the quality of life of the tenants, and the health, but there was a lack of interest in case management practices. In this study, we investigated the experience of case management practice by listening 10 case managers's experiences through FGI interview. As a result of the study, the case manager's experience is divided into four themes: 'Dilemma of support for the independent housing life after the facilities', 'Role competition between rent management and case management', 'Lonely practice for linkage and cooperation with the mainstream community support system', 'Double employment relationship and poor working environment' respectively. Based on their experiences, this study suggests practical and practical suggestions for case management of rental housing.

The primary concerns of this thesis simply stems from the curiosity of how the playwright Kim Jihoon lookouts a peculiar change of our spiritual, physical world. His lately work, , deals with a tribe of mixed blood who are either not shared by, or excluded from a national system, putting the writer's emphasis on some hints that informs us his outlook on the world. And these hints summon the following doubts. What is the significance of constituting a national community in this age, particularly in the time when the end of national people is frequently being referred? In strengthening national compositions, can the national identity be a pivotal element and central mechanism? Can the identity be able to exercise the hegemonic functions containing the political rights of decisions? Does the identity still dominate the various collective bodies such as genders, races, regions, professions, generations and classes etc? Finally, as the manifests, can the national identity be a desirable alternative that may cease both confusions and disorders evoked by the collision of heterogeneity? To find the answer, the study starts from a search for the origin of the complexities immanent in the mixed blood. The terror syndrome and the ambiguous identity, both residing outside the border of normality, will characterise the origin. Then I will focus both on the tribe's desperation itself and their present hope, in order. A myth of creating a country, making history and nationalism, all these are converged in their resistant ideology. This thesis ends with no clear conclusion, and yet suggesting the three presumptions the text insinuates: nomadism, a new barbarism, and the heterogeneity that awaits for our re-reading, and hoping that the three will lead the 'being-to-come' of the tribe, as an alternative of their future.

Purpose: The purpose of this study is to identify the effects of organizational commitment (OC) and perceived patient safety culture (PPSC) on patient safety nursing activities (PSNA) among nurses in comprehensive nursing care units. Methods: Participants were 173 nurses working at five general hospitals in Chungcheong area. Data were analyzed using descriptive statistics, 𝑥² test, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with SPSS/WIN 23.0 programs. Results: The mean scores of the OC and PPSC were 3.28±0.50 and 3.85±0.35, respectively. The mean score of PSNA was 4.55±0.41, and PSNA was significantly different by the experience of participating in hospital's safety culture campaigns (t=2.70, p=.008). The results of the multiple regression analysis showed that 'patient safety knowledge and attitudes' (β=.27, p=.006) and 'unpunished environment to error' (β=.22, p=.004) as the sub-categories of PPSC were affecting factors on PSNA with an explanatory power of 26.0% (F=6.40, p<.001). Conclusion: The results of this study suggest that in order to promote PSNA among nurses in comprehensive nursing care units, it is necessary to develop a program to enhance patient safety-related knowledge and attitudes. In addition, the hospital's organizational efforts such as operating safety campaigns and creating an unpunished environment to error should be needed.

Life table analysis and temperature-dependent development experiments were conducted to understand the biological characteristics of the cabbage aphid, Brevicoryne brassicae (Linnaeus) on detached Tah Tsai Chinese cabbage (Brassica campestris var. narinosa) leaves at seven constant temperatures (15, 18, 21, 24, 27, 30 and $33{\pm}1^{\circ}C$; $65{\pm}5%$ RH; 16L:8D). Mortality was lowest at $24^{\circ}C$ with 18% and 0% at $1^{st}{\sim}2^{nd}$ and $3^{rd}{\sim}4^{th}$ nymphal stages, respectively. The developmental period of $1^{st}{\sim}2^{nd}$ nymphal stage was 8.4 days at $18^{\circ}C$, and it decreased with increasing temperature. The developmental period of the $3^{rd}{\sim}4^{th}$ nymphal stage was 6.7 days at $18^{\circ}C$. The lower threshold temperature calculated using a linear model was $7.8^{\circ}C$, and the effective accumulative temperature was 120.1DD. Adult longevity was 14.9 days at $21^{\circ}C$, and total fecundity was observed 58.5 at $24^{\circ}C$. According to the life table, the net reproduction rate was 47.5 at $24^{\circ}C$, and the intrinsic rate of increase and the finite rate of increase were 0.36 and 1.43, respectively, at $27^{\circ}C$. The doubling time was 1.95d at $27^{\circ}C$, and mean generation time was 7.43d at $30^{\circ}C$.

Fruit drop due to Eurytoma maslovskii infestations of Japanese apricot (Prunus mume) is a serious economic issue in most parts of Jeonnam Province, with the exception of the coastal areas such as Wando, Shinan, Yeosu, and Muan. The average incidence of fruit drop was 67% in 2013 and 33.3% in 2014. E. maslovskii larvae overwinter inside the pits of Japanese apricots. Larval survival rates decrease to less than 30% after a rainy summer season. The eggs are long oval of 0.68 mm, 0.29 mm and ivory white. Mature larva is of 6.56 mm, 3.18 mm. Free pupa are black, adult females and males of 6.97 mm, 4.90 mm lengths, respectively, while the ovipositor is 0.64 mm in length. Adult emergence occurs from early April to early May, when Japanese apricot fruits are from 4 mm to 17 mm in diameter. Adults persist for 13.5 d after emergence, and the sex ratio of females to males was found th be 45.9:54.1. Although up to four eggs may be oviposited per fruit, only one larva will ultimately survive, ans the larvae are cannibalistic. The period during which E. maslovskii is able to oviposit on Japanese apricots only lasts from mid- to late April (fruit diameter: 12~16 mm). When the diameter of the fruit is >16 mm, the pit of the Japanese apricot hardens and larvae have difficultly penetrating the stone. Therefore, the most effective method of controlling this pest is to spray orchards with a control agent 2~3 times, at 5 d intervals, beginning in mid- April.

Cotesia plutellae bracovirus (CpBV) is a polydnavirus symbiotic to C. plutellae parasitizing young larvae of the diamondback moth, Plutella xylostella. Several CpBV genes play important roles in suppressing immune responses of the parasitized larvae. This study tested a hypothesis that the CpBV genes inducing host immunosuppression could be applied to develop a potent recombinant baculovirus. Based on a previous study, a recombinant baculovirus expressing CpBV-ELP1 (AcMNPV-ELP1) was selected and multiplied using larvae of the beet armyworm, Spodoptera exigua. The recombinant viruses were produced in a yield of $5{\times}10^{10}$ polyhedral inclusion body (PIB)/larva. The cultured AcMNPV-ELP1 exhibited a much higher pathogenicity against S. exigua larvae. However, its insecticidal activity was varied among larval instars of S. exigua, in which first and late instars were high susceptible. Spray of the recombinant baculovirus ($5{\times}10^6PIB/mL$) exhibited higher control efficacy (${\approx}$ 88%) against S. exigua larvae infesting cabbage than a chemical insecticide, tebufenozide, at 7 days after treatment. These results indicate that AcMNPV-ELP1 mass-cultured using host insect system is highly pathogenic and can be applied to develop a novel microbial control agent.
