  • Purpose: This study was conducted to find out the relationship among resilience, coping mechanism, social support and family strengths and to explore the predictors for school adolescents' resilience. Method: The subjects of this study were 296 high school adolescents residing in two urban area in Korea. The subjects completed self-report questionnaires measuring Resilience(Jew, et al., 1997), Coping Mechanism(Carver, et al., 1989), Social Support(Lee, 1997) and Family Strengths(Olson 1982). Results: Socio-demographic characteristics of school adolescents influencing resilience, coping mechanism, social support and family strengths were revealed. The results showed that resilience, problem-focused coping, social support and family strengths were correlated positively and self-esteem support, problem-focused coping, sibling's and mother's help, and instrumental support were the predictors of resilience of school adolescents. Conclusion: We found out the specific attributes of individual, social and family factors which predict resilience for school adolescents. These results may suggest further studies to investigate the relationship between stress and resilience, find out other predictors of resilience for Korean school adolescents, examine whether protective factors for adolescents' problem behaviors influence similarly on resilience.

  • The purpose of this study was to employ the Latent Growth Curve Model(LGM) to investigate the developmental trajectories of children's internalizing and externalizing problem behaviors and to identify predictors that might have an effect on change and the level of developmental trajectories. Furthermore, we classified the developmental trajectories of children's internalizing and externalizing problem behaviors, and also analyzed factors which caused differences in developmental trajectories by Semi-Parametric Group-based Modeling. This study used data from wave 1-4(2004~2008) of elementary school fourth grade panel of the Korea Youth Panel Survey(KYPS). The results showed that children's internalizing and externalizing problem behaviors changed significantly from the fourth grade of elementary school to the first grade of middle school. The predictors for developmental trajectories of children's internalizing problem behaviors were gender, self-control, parental conflict, deviant peers, and attachment to teachers. The predictors for the developmental trajectories of children's externalizing problem behaviors were gender, self-esteem, self-control, and deviant peers. The developmental trajectories of children's internalizing problem behaviors was classified into three groups. The developmental trajectories of children's externalizing problem behaviors was classified into four groups.

  • Statistical forecast models for the prediction of the summertime Changma precipitation have been developed in this study. As effective predictors for the Changma precipitation, the springtime sea surface temperature (SST) anomalies over the North Atlantic (NA1), the North Pacific (NPC) and the tropical Pacific Ocean (CNINO) has been suggested in Lee and Seo (2013). To further improve the performance of the statistical prediction scheme, we select other potential predictors and construct 2 additional statistical models. The selected predictors are the Northern Indian Ocean (NIO) and the Bering Sea (BS) SST anomalies, and the spring Eurasian snow cover anomaly (EUSC). Then, using the total three statistical prediction models, a simple ensemble-mean prediction is performed. The resulting correlation skill score reaches as high as ~0.90 for the last 21 years, which is ~16% increase in the skill compared to the prediction model by Lee and Seo (2013). The EUSC and BS predictors are related to a strengthening of the Okhotsk high, leading to an enhancement of the Changma front. The NIO predictor induces the cyclonic anomalies to the southwest of the Korean peninsula and southeasterly flows toward the peninsula, giving rise to an increase in the Changma precipitation.

  • One hundred two high-risk women(HRW) and 115 low-risk women(LRW) were studied at post-partal hospitalization and at 1, 4, and 8 months after giving birth to determine whether they would differ in the achievement of perceived maternal acquisition and whether predictors of maternal acquisition would differ for the two groups over time. The subjects were 102 HRW and 115 LRW, all in the above 27 weeks, admitted to two hospitals and to two clinic in the Kyoungnam area between July 1, 1998 and May 4, 1999. The data were analyzed by a SPSS program and the results are as follows ; 1) Predictors of Maternal role acquisition in the HRW were fetal attachment, maternal attachment, state anxiety, relationships of partner, social support in the early postpartum, maternal attachment, relationships of partner, depression, infant's health status in the postpartal 1 month, relationships of partner, self-esteem, educational degree in the postpartal 4 month, and maternal attachment, social supports in the postpartal 8 month. 2) Predictors of Maternal role acquisition in the LRW were fetal attachment, social supports, perceived experience about labor and delivery in the early postpartum, maternal attachment, sense of mastery in the postpartal 1 month, sense of mastery, experience with infants, relationships of partner in the postpartal 4 month and maternal attachment, experience with infants, social supports in the postpartal 8 month. 3) The hypothesis that HRW would score significantly lower on maternal competency than LRW was rejected. 4) The hypothesis that maternal acquisition would be significantly related to maternal attachment was accepted.

  • The purpose of this study was to identify the predictable variables of criteria on clothing selection. Relationships among criteria on clothing selection, psychological variable, lifestyle variable, and demographic variable were tested by Pearsons' correlation coefficients and One-way ANOVA. The predictors of criteria on clothing selection were identified by Regression. The consumers were classified into several benefit-segments by criteria on clothing selection, and then, the character of each segment were identified by Multiple Discriminant Analysis. Data was obtained from 593 women living in Pusan by self-administered questionnaires. The results of the study were as follows; 1. Relationship between criteria on clothing selection and relative variables. 1) The important variables to criteria on clothing selection were "down-to-earth-sophisticated", "traditional-morden", "conventional-different", "conscientious-expendient", need for exhibitionism, need for sex, fashion / appearance. 2) The important factor of clothing selection criteria was comfort and it has significant difference among ages. 3) The higher of social-economic status have the more appearance-oriented selection. 2. Predictors of criteria on clothing selection. There were several important predictors of criteria on clothing selection like lifestyle, need, and self-image. Especially, fashion / appearance in lifestyle variable was very important. 3. Segmentation by the criteria on clothing selection. There are four groups Classified by the criteria on clothing selection, that is practical-oriented group, appearance-oriented group, practical and appearance-oriented group, and indifference group. The significant discriminative variables were Fashion / appearance factor, need for exhibitionism, and need for sex. The result of this study can be used for a enterprise to analysis the consumer and to build the strategy of advertisement clothing.

  • Purpose: To promote condom use for young men, there is necessary to meet their varying needs for condom. The purpose of this study was to examine what predicts condom use intention according to experience of sexual intercourse among Korean male college students. The conceptual framework for the study was the theory of planned behavior and the health belief model. Methods: A cross-sectional descriptive design was used with self-report questionnaires, which were completed by 399 subjects. Logistic regression analysis was done to examine predictors of condom use intentions according to experience of sexual intercourse. Results: The susceptibility to sexual transmitted diseases/ Acquired Immune Deficiency Syndrome (STDs/AIDS) and pregnancy and benefits from condom use were significant predictors of condom use intentions in the non-experienced group. The significant predictors of condom use intention for the experienced group were barriers to condom use and condom use self-efficacy. Conclusion: These findings suggest that sex education program should be developed to overcome barriers to condom use, enhance condom use self-efficacy, and maximize the benefits from condom use as well as increase the perceived susceptibility to STDs/AIDS and pregnancy. To enhance condom use self- efficacy, practicing and increasing ability in interactive negotiation to use condom should be included.

  • In general, lecture evaluation has been used in most universities as an important criterion to evaluate quality of education. This study is exploratory research on the predictors that determine lecture evaluation in college of engineering to give practical implications for improvement of engineering education. For the exploration of predictors of lecture evaluation, the data of lecture evaluation in A College of Engineering located in the metropolitan area was used, and Decision Tree Analysis was utilized as an analysis method. As a result, the characteristics of students turned out to be the most distinct predictor comparing with those of course and instructor at lecture evaluation in college of engineering. That is, as various elements other than teaching competency influence lecture evaluation in college of engineering, it is necessary to be more careful in evaluating quality of lecture or teaching competence. Thus, a follow-up study should be conducted to adjust the influence by the predictors that instructors can hardly control.

  • Purpose: Post Stroke Depression (PSD) is one of the most common complications for stroke survivors and is associated with negative health outcomes such as disability, death. The purpose of this study was to investigate the prevalence and predictors of PSD among older Korean adults living in the community. Methods: Data collection was done using the 2014 Survey of Living Conditions and Welfare Needs of Korean Older Adults. Participants were 706 older adults who had a stroke. Logistic regression analysis was used to determine the predictors of PSD. Results: The prevalence of PSD which was assessed by the short form of the geriatric depression scale was 49.4%. In a logistic regression model, the predictors of PSD were self-rated health (OR=5.90, CI=3.70~9.40), economic state (OR=2.97, CI=2.07~4.24), independent activities of daily living (IADL) (OR=2.17, CI=1.30~3.63), Activities of Daily Living (ADL) (OR=2.02, CI=1.07~3.80), and education (OR=1.53, CI=1.05~2.24). Conclusion: PSD was common among older Korean adults living in the community. Poor self-rated health status, lower economic state, lower levels of Instrumental Activities of Daily Living (IADL) and ADL, lower levels of education should be considered when conducting activities related to prevention and management of PSD in older adults.

  • 랜덤포레스트는 여러 의사결정나무 모형들을 융합하여 안정성과 예측력을 높여주기 때문에 종종 사용되는 방법이다. 예측력을 증가시키는 반면 해석의 용이성을 희생하기 때문에 이를 보상하기 위해 변수의 중요도를 제공한다. 변수의 중요도는 랜덤포레스트를 구축할 때 변수가 얼마나 중요한 역할을 하는지를 알려 준다. 그러나 어떤 예측변수가 다른 예측변수들과 상관되어 있을 때 기존 알고리즘의 변수중요도는 왜곡될 수 있다. 상관된 예측변수들의 하향 편향은 예측변수의 중요도를 실제 중요도보다 낮게 측정하게 한다. 우리는 기존 알고리즘을 수정하여 상관 예측변수의 하향 편향을 회복하는 새로운 알고리즘을 제안한다. 제안된 알고리즘의 성능은 모의 자료에 의해 증명되고 실제 자료에 의해 설명된다.
