Subjects were 15 teachers and 143 children at 15 child-care centers in Seoul that varied by quality of care. The Child Care Program Observation Scale(Rhee et at., 2003) was employed to observe the quality of the centers. Information on teachers' participation in play was collected by 20 units of observation for each teacher using a rating scale developed by the author. Children's behaviors were observed with time sampling method in 12 categories of play behaviors based on Social and Cognitive Play Scales(Rubin et al., 1978). Children's play behaviors varied by quality of child-care centers and teachers' participation in play. When child-care quality was high, teachers' participated actively in children's play and children showed developmentally appropriate play behaviors.

The exponential proliferation of cutting-edge computing technologies has spurred organizations to outsource their data and computational needs. In the realm of cloud-based computing environments, ensuring robust security, encompassing principles such as confidentiality, availability, and integrity, stands as an overarching imperative. Elevating security measures beyond conventional strategies hinges on a profound comprehension of malware's multifaceted behavioral landscape. This paper presents an innovative paradigm aimed at empowering cloud service providers to adeptly model user behaviors. Our approach harnesses the power of a Particle Swarm Optimization-based Probabilistic Neural Network (PSO-PNN) for detection and recognition processes. Within the initial recognition module, user behaviors are translated into a comprehensible format, and the identification of malicious nano-structures behaviors is orchestrated through a multi-layer neural network. Leveraging the UNSW-NB15 dataset, we meticulously validate our approach, effectively characterizing diverse manifestations of malicious nano-structures behaviors exhibited by users. The experimental results unequivocally underscore the promise of our method in fortifying security monitoring and the discernment of malicious nano-structures behaviors.

Objectives: This study thus set out to examine the health literacy and self-care behaviors of community-dwelling elderly patients with hypertension and investigate their relations and influential factors, thus providing basic data to develop a nursing intervention program to promote self-care behaviors among hypertension patients. Methods: The subjects include 180 hypertension patients using community health centers, public senior centers, and welfare centers in Jeju. Results: The subjects scored a mean of 49.8 (${\pm}12.4$) points on health literacy and 55.8 (${\pm}6.7$) points on self-care behaviors. In the results of hierarchical regression analysis, health literacy independently predicted self-care behaviors (${\beta}=.12$, p=.050) after controlling for general characteristics, hypertension-related knowledge and self-efficacy. Conclusions: These results suggest that interventions for improving health literacy are important to enhance elder's ability of self-care behaviors. It is necessary to understand the health literacy of elderly patients with hypertension before providing them with educational intervention and information and to develop appropriate educational materials and intervention programs.

This study investigated: 1) what weight-related behaviors college students practiced; 2) if the behaviors were performed for weight-related reasons; and 3) whether the behavioral practices differed by gender, race, and body weight status. This cross-sectional study used a questionnaire to collect information from a non-probability sample of undergraduate students (n=379; 48% men) recruited from large introductory psychology classes. Chi-square tests were conducted to examine simple comparisons, and multiple logistic regression analyses assessed differences. Male students reported adopting significantly fewer weight-related behaviors than females. Most frequently males increased exercise (69.2%), increased fruit and vegetable consumption (50%), skipped meals (46%), cut out sweets and junk foods (40%), and cut out between-meal snacks (35%). Female students most frequently increased exercise (67.4%), skipped meals (63%), increased fruit and vegetable consumption (62%), reduced the amount of food eaten (60%), and cut out between-meal snacks (51%). Negative behaviors were engaged in by only a few participants. Weight-related reasons were a significant factor for weight-related behavior adoption. Multiple logistic regression analyses showed that gender was consistently and significantly associated with the adoption of weight-related behaviors, while race and weight status were less consistently associated. Findings of this study will be helpful to dietitians who counsel college students. Results of this study may support effects to bring more comprehensive behaviorally-focused health md nutrition interventions to college campuses.

The purpose of this study was to investigate the clothing and cosmetics purchasing behaviors of middle aged male consumers according to objectified body consciousness. The subjects were 329 male adults aged from 40 to 59, and measuring instruments consisted of objectified body consciousness, clothing and cosmetics purchasing behaviors, and subjects' demographics attributions. The data were analyzed by factor analysis, cluster analysis, multiple response analysis, cross tabs analysis, and $x^2$ test using the SPSS program. The results were as follows. First, three factors (body shame, body surveillance, and control belief) emerged on objectified body consciousness. Second, subjects were divided into 2 groups (objectified group and non-objectified group) by objectified body consciousness. Third, these two consumer groups showed many differences regarding clothing and cosmetics purchasing behaviors. The objectified group showed many more positive clothing and cosmetics purchasing behaviors than the non-objectified group in terms of purchase motives, selection criteria, information source, purchase place, and purchase cost per month. These results show that objectified body consciousness is a useful variable for understanding adult male clothing and cosmetics purchasing behavior and to segment the male consumer market effectively.

Dieting behaviors prevail among most women and are highly increasing among female adolescents who don't have to lose weight. The dieting behaviors of normal or low weight groups are highly related to the negative impact of health risk behaviors. We need a strategy for intervening in the dieting behaviors of relevant groups. With this background, a study was conducted to examine the current situation of dieting behaviors and related factors in middle school girls, and to provide guidelines for the relevant dieting group. This survey was carried out by self-questionnaires passed out to 901 middle school girls from 3 middle schools in Seoul. Data were collected from April 10th, 2000 to April 17th, 2000 and 794 respondents' data were finally selected for analysis. The instruments of this study were Shin's scale for effects of mass-media, Birleson's depression self-rating scale translated by shim, Rosenberg's self-esteem scale, Smilkstein's Family APGAR score translated by Yoon, Kim's school-related adjustment scale. The credibility of instruments was 0.41~0.83 in the pilot study and 0.70~0.86 in the main study. The summary of results was as follows: 1. The general characteristics of respondents were analyzed. In comparison of grade and dieting behaviors, the subjects of the group perceived that their body image was obeser than their real body image and their ideal body image was slenderer than their current body image. A dieter's body image was seriously distorted. 2. The dieting behaviors were analyzed. The Subjects' BMI was within the normal to low range -- they didn't have to lose weight. But actually 47.3% of the respondents were dieters. Their main dieting methods were exercise(71.8%), computer games(64.9%) such as DDR and pump, and intake reduction(64.1%). Most dieters were using desirable methods such as exercise and intake control. But unhealthy methods such as saunax, smoking and harmful drug-use were also used by a few dieters. The main reason for dieting was attractiveness. The chief resources of dieting methods were mass-media(67.8%), friends(64.3%), and parents & relatives(35.1%). Only a few subjects obtained the information from health professionals. While they were trying to lose weight, 42.1% of the subjects experienced side effects such as dizziness(45.0%), apathy(20.5%), appetite loss(18.5%), amenorrhea and the irregularity of the menstrual cycle(16.6%). 3. The relationship between dieting behaviors and factors was analyzed. Dieting behaviors were significantly related to the experience of menarche, the experience of dating with heterosexuals, perceived body image, self-esteem, depression, family's relationship, school instruction-related adjustment, school life-related adjustment, and the effect of mass-media. After that, the multiple logistic regression was used. The analysis revealed that dating, perceived body image, the experience of menarche and the effect of mass media were significant factors. In conclusion, strategies for preventing irrelevant dieting behaviors are urgently required to enhance female adolescents' ability to choose the right information from countless others and to recognize their optimum body image.
