An earthworm survey of Busan metropolitan area unearthed a dozen taxa in four families (including Enchytraeidae). Members of mostly common, cosmopolitan earthworm species-complexes were: Drawida cf. koreana Kobayashi, 1938, Amynthas cf. corticis (Kinberg, 1867), Aporrectodea trapezoides (Dug$\grave{e}$s, 1828) and Eisenia fetida (Savigny, 1826). Also found were Amynthas hupeiensis (Michaelsen, 1895), A. masatakae (Beddard, 1892) and Metaphire ryunome Blakemore, 2012 - the latter a new Korean record. New taxa are: moniligastrid Drawida songae yeongdo subsp. n.; megascolecid Amynthas carnosus roki subsp. n. which is compared to nominal taxon A. carnosus (Goto and Hatai, 1899) from Japan, to A. carnosus monstriferus (Kobayashi, 1936) stat. n. from Korea and to A. lichuanensis Wang and Qiu, 2005 stat. n. from China; plus lumbricid Eisenia japonica vaga subsp. n. deemed an objectively-based molecular taxon on its unique DNA COI gene barcode. Restoration of Eisenia xanthurus (Templeton, 1836) for E. andrei is mooted (in Appendix).

This study is to test some expected performances coming from the introduction child care electronic voucher system, and suggest some policy implications. At first, this study established causal model on the expected performances of child care electronic voucher system, and then tested it through structural equation model on the base of survey. Survey was made through sampling employees of child care facilities in Gwangju Metropolitan City. This study showed that the expected effects of child care electronic voucher system are significant. This study suggested some implications basing on this analytical results.

This survey examined sex role identities (androgyny, masculinity, femininity, and undifferentiated), gender, and academic achievement scores from an international sampling of college students. For a comparison, American students and Korean students responded to survey questions on the Bem Sex Role Inventory and the Korean Sex Role Inventory respectively, reported family socio-economic status and achievement scores on the American College Testing (ACT) or Korean Scholastic Ability Test (KSAT). Results in this study indicate that a higher percentage of American students report an androgynous or undifferentiated gender role identity than do Koreans, while Korean students are more likely to show a feminine gender role identity than Americans. Although American students reported higher levels of androgyny in their gender role identity, those who fit the feminine gender role identity group showed higher ACT scores than other gender role identity types. However, in the Korean sample, the masculine gender role identity produced a higher academic achievement for both males and females.

This study explored the effects of expectatioin, performance, and disconfirmatoni on satisfaction of theme park users. Everland was chosen as the study area, and 260 users were selected by the nonprobability sampling. In expectation disconfirmation paradigm, expectation should be measured before purchase, and performance, disconfirmation and satisfaction should be measured after purchase. An entrance survey was done to measure expectation, and an exit survey to measure performance, disconfirmation, and satisfaction. Maximum likelihood method was used to estimate structural equation model by the LISREL 7.2. Performance had the most significant effect on satisfaction among three variables. The satisfaction of theme park users depends largely on it, therefore, the consideration of visitors' performance should e essential for managers.

Balanced Repeated Replication(BRR) is widely used to estimate the variance of linear or nonlinear estimators from complex sampling surveys. Most of survey data sets include imputed missing values and treat the imputed values as observed data. But applying the standard BRR variance estimation formula for imputed data does not produce valid variance estimators. Shao, Chen and Chen(1998) proposed an adjusted BRR method by adjusting the imputed data to produce more accurate variance estimators. In this paper, another adjusted BRR method is proposed with examples of real data.

A Health Interview Survey at Chuncheon city was conducted to assess level of illness by stratified random sampling method. Sample size was 6,007 and the prevalence of illness in period of 15 days was studied. 1) Prevalence rate of illness among Chuncheon citizen was 20.8 percent, and that of acute condition was 10.8 percent and chronic condition, 10.0 percent. 2) There was significant difference in prevalence rate by sex, especially the prevalence rate of chronic illness. 3) High positive correlation was noted between aging and prevalence rate of chronic illness. But negative correlation was noted in case of acute illness. 4) Multiple regression analysis on morbid state by socioeconomic variables was not seen to be appropriate for this survey, especially the analysis of acute illness. 5) Estimation of anual prevalence rate could not be possible because of seasonal variation of disease prevalence.

Objectives: This study is aimed to analyze service user's benefit and perceived-outcomes of visiting healthcare. Methods: Using a questionnaire survey we analyzed the subjective service quality and satisfaction of survey respondents. The sampling was designed with socioeconomic characteristics(age, sex, user group et al.), and each respondent (N=1,000) was presented with double-bounded dichotomous choice questions. To measure the value of visiting healthcare, we employed a contingent valuation method. Results: The respondents were satisfied with service and quality on visiting healthcare. And the acceptance-to-pay of respondent's benefit was 50,458 won for each visit and in totality, service user's benefit was 185.9 billion won. Conclusions: It is necessary to invest in visiting healthcare in public health centers.
