  • To assess short-term variation of summer phytoplankton community structure in different water masses, phytoplankton and environmental factors were monitored from 31 stations on and off the southern coasts of Korea, from June 18 to June 20 2009. According to multidimensional scaling (MDS) and cluster analysis based on phytoplankton community data from each station, the southern sea was divided into two groups. The first group included stations in the south-eastern region of Jeju Island, which is strongly influenced by the Kuroshio warm current. The second group located along the coastal region of the southern sea, which was mainly comprised of Bacillariophyceae and Crytophyceae. Of these stations, St. 13 and 28 formed a temperature front caused by different hydrological conditions. In particular, nutrients and Chl.a concentrations in these two stations were significantly higher compared to those in the other stations. This indicates that phytoplankton population and subsequent microalgal growth under high nutrient concentrations vary in different water masses. Our results support the theory that phytoplankton community structure in the southern sea of Korea can be influenced on a short-term scale by different water masses and currents.

  • This study aims 1) To explicate the multidimensional structure of a widely used measure of subjective well-being, the Philadelphia Geriatric Center(PGC) Morale Scale is used to measure health in elderly populations and 2) To examine the relationship between the socioeconomic status and related variables, health and physical disability and subjective well-being in elderly populations. The selection of subjects was determined through a survey of 672 rural dwelling elderly persons(269 males and 403 females) aged 60 years and over. The respondents were interviewed by 18 trained health workers using the questionnaire from July 4 to July 9 in 1994. The subjects were surveyed again during the period from August 1 to August 6 in 1994 to conform the questionnaire's reliability. Subjective well-being was evaluated using the Revised Questionnaire of the Philadelphia Geriatric Center(PGC) Moral Scale(17 items, Lawton, 1975). The results are as follows : 1) The item scores were intercorrelated and subjected to a principal component analysis. A rotated three-factor solution was done, accounting for 40.9% of the total variance. Thus, the PGC morale Scale can be derived from three stable factors : Factor 1 was explained "Lonely Dissatisfaction(7 items)", Factor 2 was explained "Agitation (5 items)", Factor 3 was explained "Attitude Towards Own Aging (5 items)". Further, these factors have a high degree of internal consistency, as determined by Cronbach's alpha : 0.7852. 2) The total mean score of PGC Morale Scale was 8.73. Sex, Age, Education, Current disease, Family type, Economic status, ADL, IADL were significantly difference in mean scores of PGC morale scale. 3) In the results of stepwise multiple regression analysis of subjective well-being. the most contributing factors were economic status, IADL, current disease, family type, sex and the R square was 0.23.

  • The purpose of this study was to investigate the moderating effect of parent's neglectful behavior on children's irrational beliefs and their style of expressing anger. The subjects consisted of 354 5th and 6th grade elementary school children. The instruments used were the Multidimensional Neglectful Behavior Scale (Straus et al., 1995), the Irrational Belief Scales (Lee, 2004), and the Anger Expression Scale (Spielberger, Krasner, & Solomon, 1988). Data were analyzed by means of both descriptive statistics and hierarchical regression analysis using the SPSS 18.0. The result of this study indicated that there were significant correlations between parent's neglectful behavior and the irrational beliefs and style of anger expression exhibited by the children concerned. Hierarchical regression analysis indicated that, the effects of children's irrational beliefs on their anger was moderated by parent's neglectful behavior. The effects of children's irrational beliefs on their anger control was also moderated by parent's neglectful behavior. In conclusion, parent's neglectful behavior has a moderating effect upon a child's irrational beliefs as it relates to the style of anger expression as exhibited by their children.

  • Library anxiety has been recognized as one of the representative fields that concerns user's affectivity in library and information study. Considerable library users have been discovered to experience library anxiety according to researches. Although digital libraries are becoming more popular changing drastically from traditional libraries, few studies have addressed the measurement of digital library anxiety(DLA). The purpose of this study is to develop and validate a multidimensional digital library anxiety scale(DLAS) based on previous research in library anxiety and digital libraries. It will become possible to define the construct of DLAS, provide its underlying dimensionalities, and find out how much they explain the construct. Through the exploratory factor analysis, DLAS has been developed with 39 items representing seven distinct factors which were interpreted as affect, resources, know-how, security, language, technology, and task explaining 51.165% of DLA. Also, DLAS' characteristics about demographic variables and use pattern were found through the T-test and ANOVA analysis for each factor.

  • Purpose: The purpose of this present study was to develop and evaluate the psychometric properties of a needs scale for patients with cancer undergoing follow-up care (NS-C). Methods: A preliminary NS-C of 48 was derived from literature reviews and in-depth interviews with patients with cancer. Content validation of the items was established by oncology physicians and nurses. Each item was scored on a five-point Likert scale. The preliminary NS-C and Eastern Cooperative Oncology Group (ECOG) performance status questionnaires were administered to 873 patients with cancer recruited from three university hospitals. The data were analyzed using factor analysis, multidimensional scaling analysis, ANOVA, Pearson correlation coefficients, and Cronbach's alpha. Results: From the factor analysis, 25 significant items in six subscales were derived. The subscales were named physical symptoms, diet and exercise, support, relationship with health professionals, treatment/prognosis, and keeping mind under control. The NS-C also established item convergent and discriminant validity, and known-groups validity. Cronbach's alpha of the subscales ranged from .90 to .92. Conclusion: This study suggests that the NS-C is an easy, reliable and valid instrument to measure the needs of patients with cancer. Health professionals may use the NS-C for patients with cancer both in practice and research.

  • Objective : The purpose of this study is to investigate the relationship among the degree of symptoms of posttraumatic stress disorder (PTSD) and social support, stress coping strategies, and self-esteem in patients with PTSD. Methods : A total of 48 patients meeting DSM-5 criteria for PTSD and 48 normal controls were recruited for participation in this study. We evaluated subjects using the Clinician-Administered PTSD Scale (CAPS), Hamilton Anxiety Scale (HAM-A), Hamilton Depression Scale (HAM-D), Rosenberg Self-Esteem Scale (RSES), Multidimensional Scale of Perceived Social Support (MSPSS) and The Ways of Stress Coping Questionnaire (SCQ). We analyzed data using an independent t-test and Pearson's correlation analysis. Results : In PTSD patients, total CAPS scores showed a significant positive correlation with HAM-A and HAM-D scores and a significant negative correlation with MSPSS scores. RSES scores showed a significant positive correlation with MSPSS and SCQ scores. MSPSS scores showed a significant negative correlation with PTSD avoidance and numbing and HAM-D scores. SCQ scores showed a significant negative correlation with PTSD avoidance and numbing. Conclusion : These results revealed that the better the stress coping strategies and social support, the lower the degree of symptoms in patients with PTSD. In addition, it was found that the higher the social support and self-esteem, the lower the degree of depression and anxiety. Therefore, in the treatment process, it seems important to identify and correct the self-esteem, social support system, and stress coping strategies of patients with PTSD.
