A review on the papers published in the Korean Journal of Air-Conditioning and Refrigerating Engineering in 2000 and 2001 has been done. Focus has been put on current status of research in the aspect of heating, cooling, ventilation, sanitation and building environment. The conclusions are as follows. (1) Most of fundamental studies on fluid flow were related with heat transportation of facilities. Drop formation and rivulet flow on solid surfaces were interesting topics related with condensation augmentation. Research on micro environment considering flow, heat, humidity was also interesting for comfortable living environment. It can be extended considering biological aspects. Development of fans and blowers of high performance and low noise were continuing topics. Well developed CFD technologies were widely applied for developing facilities and their systems. (2) Most of papers related with heat transfer analysis and heat exchanger shows dealt with convection, evaporation, and channel flow for the design application of heat exchanger. The numerical heat transfer simulation studies have been peformed and reported to show heat transfer characteristics. Experimental as well as numerical studies on heat exchanger were reported, while not many papers are available for the system analysis including heat exchanger. (3) A review of the recent studies on heat pump system shows that performance analysis and control of heat pump have been peformed by various simulations and experiments. The research papers on multi-type heat pump system increased significantly. The studies on heat pipe have been examined experimently for change of working characteristics and strut lure. Research on the phase change has been carried out steadily and operation strategies of encapsulated ice storage tank are reported experimentally in several papers. (4) A review of recent studies on refrigeration/air conditioning system have focused on the system performance and efficiency for new alternative refrigerants. Evaporation and condensation heat transfer characteristics are investigated for tube shapes and new alternative refrigerants. Studies on components of refrigeration/air conditioning system are carried to examine efficiency for various compressors and performance of new expansion devices. In addition to thermophysical properties of refrigerant mixtures, studies on new refrigerants are also carried out, however research works on two-phase flow seemed to be insufficient. (5) A review of the recent studies on absorption cooling system indicates that heat and mass transfer phenomena have been investigated to improve absorber performance. Various experimental data have been presented and several simulation models have been proposed. A review of the recent studies on duct and ventilation shows that ventilation indices have been proposed to quantify the ventilation performance in buildings and tunnels. Main efforts have been focused on the applications of ventilation effectiveness in practice, either numerically using computational fluid dynamics or experimentally using tracer gas techniques. (6) Based on a review of recent studies on indoor thermal environment and building service systems, research issues have mainly focused on many innovative ideas such as underfloor air-conditioning system, personal environmental modules, radiant floor cooling and etc. Also, the new approaches for minimizing energy consumption as well as improving indoor environmental conditions through predictive control of HVAC systems, various activities of building energy management and cost-benefit analysis for economic evaluation were highlighted.

This study aimed to investigate primary students' science-related attitudes through the literature review. Ninety-four papers published in domestic science education journals, since 1990, were collected and were followed by content analysis. In this study, science-related attitude was conceptualized as attitude toward science, scientist, science-related occupations, and school science, which is composed of cognitive, affective and behavioral domains. Based on the conceptualization, the instruments used for measuring students' attitudes were analyzed. The analysis of definition of science-related attitude in the articles showed different foci on cognitive, affective and behavioral domains. To suggest the effective instruction for enhancing students' science-related attitudes, this study identified students' attitude with gender, grade, residence and achievement level. The result showed that male, urban, higher-grade and better performed students had more positive attitude than female, rural, lower-grade and less performed students. As for the factors in science-related attitude, I categorized the factors into personal, environmental and pedagogical aspects, and found that psychological elements in all domains were most influential to students' change of science-related attitudes. It is interesting to note that students showed dichotomous views about experiment and that task-oriented instruction failed to enhance students' attitude. Based on the research findings, this study suggests effective instruction for improving students' attitudes and future research for science education.

The purposes of this study were to describe 12 years of patient-related oncology nursing research in Korea, identifying various nursing interventions, and assesing the effectiveness of the interventions, through analysis and synthesis of the accumulated research papers. One hundred and seventy-nine studies were selected for this study and these were mostly descriptive in design (69.2%). Of the 179 studies, 25 met the criteria for meta-analytic treatment. Twenty-five experimental studies were found in theses and dissertations (68%), 92% used convenience sample, and the median sample size was 40. Subjects were predominantly in treatment and rehabilitation (76%). Most studies(68%) were not derived from a theory base, with only 8% reporting use of a nursing theory. Results of the meta-analysis are as follows. The effect size of the nursing intervention type was found to be significantly effective. The standardized mean difference ranged from a high positive of 2.55 to a low negative of -0.22. Direct personal nursing intervention method was more effective than indirect group method. Two nursing intervention methods were more effective than one. The greatest effect size was thyxical intervention. The greatest mean effect size was scalp hypothermia technique. Teaching was a frequent intervention after 1990, although a wide range of treatments were studied. Effect size of intervention for symptom management was largest in relieving pain. Effective intervention method for relieving anxiety was exercise.

To invigorate and develop marketing strategies in public performance, this thesis reviewed the literatures such as papers, academic materials and internet information on marketing in public performance. We performed surveys for specialists and non-specialists of public performance from on-line or off-line for questionnaire which is classified as demographic characteristics, tendency for seeing public performance and for knowledge of NFC and LBS, and analyzed the questionnaires for knowing the effects of NFC and LBS marketing in public performance. This thesis revealed generally a higher level of satisfaction with NFC than LBS, especially for specialists as compared with non-specilists. The reason of a lower level of satisfaction with LBS than NFC is that LBS technique has privacy problem about personal information by exposing the user location information. The reason of a lower level of satisfaction with NFC to non-specialists is that there are insufficiency of promotion for NFC technique and contents utilizing NFC. A total average score for a level of satisfaction of NFC and LBS service was revealed high as more than 3.50 out of 5.00. Through this thesis we suggest the public performance marketing strategies.

This study aims to investigate the concepts and characteristics of Metrosexual and Ubersexual image which are the recent fashion phenomena representing the lifestyles of comtemporary men, and to analyze the design of contemporary men's fashion based on the represented characteristics of these sexual images. To accomplish these ends, various related publications, articles and papers, divers serial publications, and numerous internet articles are collectively reviewed for theoretical studies, and design analysis are conducted for content analysis(style, color, material, detail, etc) using photo data taken from the collections from 2001 through 2006. The results of this study shows that recent appearance of Metrosexual and Ubersexual fashion image represents the change of aesthetic standards in the contemporary society. With the influence of sociocultural phenomena which allow the pursuit of individual personality, the contemporary men, instead of expressing the socialized sexual identity, came to acquire the freedom of sexual identity which represents their personal desires. As an expression of hmnan will to pursue unrestricted sensibility and aesthetic sense, these sexual phenomena of Metrosexual and Ubersexual will be reinterpreted and reappear in various forms as the social atmosphere and aesthetic standards changes.

The purpose of this study is to contribute to evidence-based nursing care for patients with chronic conditions by understanding the attributes of the health motivation concept for their health-related behaviors. Fourteen academic journals and research papers on the health-related motivation of chronically ill patients were selected according to the conceptual analysis stages of Walker and Avant, and the concept was analyzed through additional literature review. The following three factors were extracted as the attributes of health motivation of chronically ill patients: first, psychological needs for healthy behavior; second, the multidimensional state considering personal characteristics; and third, emotional strengths that can change and induce behavioral changes. Given the antecedents, attributes, and outcomes analyzed in this study, it is anticipated that the evidence-based systematic management of chronically ill patients will be possible through the application of a nursing intervention program that increases health motivation
