A study has been performed on perception of citizens about the medical insects (house flies, mosquitoes, cockroaches) in Chang Won city. A total of 375 subjects (male: 180, female: 195) was surveyed in October 1997. Cockroaches were the most dislike of medical insects to the dwellers. At a residence, cockroaches were the most troubled insects although mosquitoes were the most frequently appeared insects. Also, the most troubled insects were the cockroaches at hospitals, departments, coffee shops, and bars; the mosquitoes at theaters and parks; and the house flies at restaurants in the city. The cockroaches had the highest negative opinion score as a 4.4 point of a 5.0 point. About half of the subjects had extremely suffered from the mosquitoes (52.8%) and cockroaches (51.8%). House residents controlled house flies using fly swatters (50.0%) and insecticide sprayers (38.9%), but apartment residents controlled them using the sprayers (50.8%) and fly swatters (36.5%). The mosquitoes were controlled by using the sprayers (51.6%) and mosquito coils (36.4%). The cockroaches were controlled by using toxic baits (32.9%) and the sprayers (31.5%). Only 10% of the subjects were satisfied control management against the medical insects. The subjects wanted to more effectively control against cockroaches (39.9%) and mosquitoes (37.9%).

The purpose of this study was to review the current studies on community attachment and its related variables to suggest directions for community attachment studies in Korea. Specific objectives of the study were to search the current studies on community attachment, to search for the significant variables related to community attachment, and to draw implications for community development in Korea. The major findings of the study were as follows; 1) Current studies on community attachment used individual characteristic variables such as length of residence in the community, age, size of population and density as major independent variables. 2) Studies on community attachment used community participation, social and cultural environment as major dependent variables, however, both independent variables and dependent variables were used interchangeably in many cases. 3) Recent studied on community attachment employed community economic and cultural variables, however, studies on community attachment in Korea was relatively limited in terms of quantity as well as quality. 4) Further research on community attachment should be conducted by utilizing various independent and dependent variables in various communities to increase the community attachment in rural and urban communities to further strengthen community development in Korea.

This survey was carried out using a self-administered questionnaire in order to investigate the flavor enhancer products questionnaires were used out of 505 collected (collection rate : 84.2%). Most housewives used flavor enhancer products. Housewives with higher educations and employed housewives used significantly less flavor enhancer. The main reason for nonuse of flavor enhancer products was their perceived negative health effects. Housewives mainly used flavor enhancer products in stews and whole dishes. Most housewives used flavor enhancer products 1-2 times per day and housewives with higher educations and employed housewives used flavor enhancer products less frequently. As for the quantity of flavor enhancer products used, most housewives reported small to moderate amounts. Housewives with higher educations used significantly smaller amounts of flavor enhancer products. There was a significant difference in the kinds of flavor enhancer products used by housewives, depending on education level, household income, food expenditures and residence type. Most housewives purchased flavor enhancer products at wholesale marts. There was a significant difference in the places where flavor enhancer products were purchased among those of different education and household income levels. Therefore, these results may be useful in the development of safer and more variously flavored flavor enhancer products.

Mucoadhesive microspheres were prepared by interpolymer complexation of chitosan with poly(acrylic acid) (PAA) and solvent evaporation method to increase gastric residence time. The chitosan-PAA complex formation was confirmed by differential scanning calorimetry and swelling study. The DSC thermogram of chitosan-PAA microspheres showed two exothermic peaks for the decomposition of chitosan and PAA. The swelling ratio of the chitosan-PAA microspheres was dependent on the pH of the medium. The swelling ratio was higher at pH 2.0 than at neutral pH. The results indicated that the microspheres were formed by electrostatic interaction between the carboxyl groups of PAA and the amine groups of chitosan. The effect of various process parameters on the formation and morphology of microspheres was investigated. The best microspheres were obtained when 1.5% of the high molecular weight chitosan and 0.3% of PAA were used as an internal phase. The optimum internal phase volume was 7%. The com oil was used as the external phase of emulsion, and span 80 was used as the surfactant. The prepared microspheres had spherical shape.

The influence of emulsion type of tegafur, an oral anticancer agent, on lymphatic transport was studied in rats. The water-in-oil-type of emulsion and the oil-in-water-type emulsion of tegafur each in 50 mg, calculated in terms of tegafur, were prepared by adding tegafur aqueous solution to sesame oil containing hydrogenated castor oil following ultrasonic treatment, and then the prepared emulsions and aqueous solution as a comparative formulation were administered orally to rats (50 mg/5 ml/kg). The concentration levels of tegafur in plasma of femoral artery and lymph from thoracic duct cannula were measured simultaneously along a time course after administration and the pharmacokinetic parameters were investigated. At the same time, we examined the above described factors of 5-FU which is known as an active metabolite of tegafur. In comparison with tegafur solution, AUC and mean residence time of plasma tegafur were significantly increased in w/o-emulsion but significantly decreased in o/w-emulsion. Lymph flow rates were similar in both solution and w/o-emulsion but half in o/w-emulsion. Ratios between area under the lymph and plasma concentration time curves were always less than 1 reflecting the passive lymphatic delivery after oral administration of the prepared tegafur emulsions, but those to the 5-FU in the case of w/o-emulsion were more than 1. These results suggested that lymphatic delivery of tegafur by w/o-emulsion was more effective than that by o/w-emulsion due to its differences of formation ability of chylomicrons.

Purpose: The aim of this study was to compare the factors of health-related quality of life in older adults according to the type of residency. Methods: A cross-sectional comparative study was conducted. The subjects were 114 institutionalized older adults and 99 community dwelling older adults. Data were collected through face-to-face interviews by nurses using structured questionnaires composed of SF-36 (ver.2) and CGA-SF. Results: The institutionalized older adults had more health problems and experienced lower quality of life compared to community dwelling older adults. Factors influencing health-related quality of life for institutionalized older adults were social support, educational level, and ADL, which explained about 25.7% of the total variance, while thoseof community dwelling older adults were IADL, experiencing fall, and weight loss, which had explanatory power of 31.8%. Conclusion: These results indicate that differentiated nursing strategies according to the type of residency are required to promote health-related quality of life for older adults.

In this study, we collected 200,578,703 geo-tweets and removed the twitter bots. Using the concept of activity radius, Twitter users are classified. Users are also divided first into domestic and overseas, and again domestic ones are divided into locals and non-locals. Statistical characteristics of activity strength and active area of Twitter users are described according to activity radius and home region, and the geographical distribution is presented visually. Through a case study of Las Vegas, we have identified the difference in activity strength and active area by the user's home residence. We expect to derive theories about human mobility by analyzing various cities with the method proposed in this study.

Purpose: The purpose of this study was to examine the levels of self-esteem and resilience and to investigate factors affecting on the resilience among nursing students. Methods: The subjects for this study were 175 nursing students and the data were collected from November 15 to December 20, 2016. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficients and multiple regression. Results: Subjects' mean scores of self-esteem and resilience were 3.60 and 3.78, respectively, on a 5-point scale. There were significant differences in the level of resilience among grade (F=3.30, p<.001). The post-hoc test showed that the resilience level of the fourth-grade subjects was significantly higher than that of the third-grade. There were no significant differences in the level of resilience according to gender, religion, residence type, and economic level. Self-esteem was positively correlated with resilience (r=.80, p<.001) and economic level (r=.20, p=.007). The results of the multiple regression analysis showed that self-esteem was a significant predictor for resilience (β=.81, p<.001) which explained 64.7% of the total variance. Conclusion: Self-esteem was an significant factor for nursing students' resilience. Therefore, intervention strategies should be developed for nursing students to improve their self-esteem.
