The purpose of this study was to discuss the papers of social welfare field that were published in Korea, from a research methodology aspect in accordance with the meta-analysis reporting standard proposed by the United States Psychological Association. To this end, an analysis was conducted according to 5 types of conformity (title and abstract, introduction, methods, results and discussion) on the target subjects of 26 meta-analysis papers of social welfare field. The analysis results showed, first, the conformity in the title and abstract showed good results except for the suggested topics for meta-analysis methods. Second, in terms of the conformity of the introduction, the descriptions seemed to be good in a number of items. Third, for the conformity in the methods, the overall reporting standard was seen to be lacking and, in particular, the reporting standard for the coding procedure was seen as being very deficient. Fourth, the conformity in the results showed that the assessment of research quality and the magnitude of efficacy for each individual study, sample size, and the contents of the provided tables, summary of tables and graphs, including the study results, were not being properly reported. Fifth, the conformity in discussions was seen to be generally sound. Based on such results, by providing a reporting standard and perspective needed for ensuring feasibility that can be used to assess meta-analysis study materials, this study was aimed at presenting implications for the academic advancement of field of social welfare.

In these days, agricultural products are regarded as a core income source in tourism villages. Nevertheless, poor packaging of agricultural products has threatened the competitiveness and quality of products. For farmers, it is less likely to employ individual designer for developing and improving their packages due to low accessability to rural villages and budgets. Based on this background, this study conducted 'Charrette' in order to improve agricultural product packaging. The target village was 'Goraday' in Gangwon province. This study consisted of different steps for building and implementing proper 'Charrette' programs. Then, it also conducted empirical investigation about the effectiveness and efficiency of 'Charrette'. 'Charrette' has made progress as follows; first step was concerned with advance preparation for constructing program. Second, implementation of 'Charratte' included data collection and analysis, and development of design. Third, evaluation and feedback stage have given presentation and discussion about suggested design with local residents. Empirical investigation about the effectiveness and efficiency of 'Charrette' has been composed with survey and interview targeting participants. In survey and interviews, designers were asked about their attitudinal changes in relation to knowledge, recognition, function, motivation, and satisfaction toward 'Charrette' and 'agricultural product package design' before and after participating the event. The results showed that knowledge and perception of designers toward 'agricultural product package design' have positively increased. In addition, it revealed that designers were satisfied with collaborations with others and their contribution to rural community business. However, the results also suggested that sufficient preparation time/schedules and opportunity to meet other and farmers before events would be required to have better communication and understanding in relation to their tasks and role distribution. Furthermore, it is also required for designers to hold relationship with local community in order to actualize their packaging design.

In the main target area of the block II, Targe-scale faults occur below the unconformity developed around 1 km in depth. The contrast of seismic velocity around the unconformity is generally so large that the strong multiples and the radical velocity variation would deteriorate the quality of migrated section due to serious distortion. More than 15 kinds of data processing techniques have been applied to improve the image resolution for the structures farmed from this active crustal activity. The bad and noisy traces were edited on the common shot gathers in the first step to get rid of acquisition problems which could take place from unfavorable conditions such as climatic change during data acquisition. Correction of amplitude attenuation caused from spherical divergence and inelastic attenuation has been also applied. Mild F/K filter was used to attenuate coherent noise such as guided waves and side scatters. Predictive deconvolution has been applied before stacking to remove peg-leg multiples and water reverberations. The velocity analysis process was conducted at every 2 km interval to analyze migration velocity, and it was iterated to get the high fidelity image. The strum noise caused from streamer was completely removed by applying predictive deconvolution in time space and ${\tau}-P$ domain. Residual multiples caused from thin layer or water bottom were eliminated through parabolic radon transform demultiple process. The migration using curved ray Kirchhoff-style algorithm has been applied to stack data. The velocity obtained after several iteration approach for MVA (migration velocity analysis) was used instead or DMO for the migration velocity. Using various testing methods, optimum seismic processing parameter can be obtained for structural and stratigraphic interpretation in the Block II, Yellow Sea Basin.

InGaN material is being studied increasingly as a prospective material for solar cells. One of the merits for solar cell applications is that the band gap energy can be engineered from 0.7 eV for InN to 3.4 eV for GaN by varying of indium composition, which covers almost of solar spectrum from UV to IR. It is essential for better cell efficiency to improve not only the crystalline quality of the epitaxial layers but also fabrication of the solar cells. Fabrication includes transparent top electrodes and surface texturing which will improve the carrier extraction. Surface texturing is one of the most employed methods to enhance the extraction efficiency in LED fabrication and can be formed on a p-GaN surface, on an N-face of GaN, and even on an indium tin oxide (ITO) layer. Surface texturing method has also been adopted in InGaN-based solar cells and proved to enhance the efficiency. Since the texturing by direct etching of p-GaN, however, was known to induce the damage and result in degraded electrical properties, texturing has been studied widely on ITO layers. However, it is important to optimize the ITO thickness in Solar Cells applications since the reflectance is fluctuated by ITO thickness variation resulting in reduced light extraction at target wavelength. ITO texturing made by wet etching or dry etching was also revealed to increased series resistance in ITO film. In this work, we report a new way of texturing by deposition of thickness-optimized ITO films on ITO nano dots, which can further reduce the reflectance as well as electrical degradation originated from the ITO etching process.

Objectives : The purpose of this study was to examine psychological characteristics of patients who visited psychiatric clinic for medical certificate for military service using MMPI-2-RF. We compared target group with general psychiatric patients with same age range. Methods : A total of 165 male patients for medical certificate and 154 general psychiatric patients were collected from the Department of Psychiatry of three university hospitals. There were significant differences of age and educational level between two groups. We used independent t-test, ANCOVA, ${\chi}^2$ test to examine differences between two groups. Results : Medical certificate group scored higher on the validity scales, the Higher-Order(H-O) scales, the Restructured Clinical(RC) Scales, the Specific Problems(SP) Scales, and the Personality Psychopathology Five (PSY-5) Scales. Especially, EID, RC7, HLP, SFD, SAV, SHY, DSF, and INTR-r showed significant differences between two groups on all three statistical tests. Conclusions : The present study showed that psychiatric patients who received psychological evaluation for military service have significantly higher emotional distress, helplessness, lower self-confidence, and lower quality of interpersonal relationships. And the difference of validity scales between two groups could be related with psychological burden of compulsory military service in the study sample which causes elevation on scales of infrequent responses. MMPI-2-RF would be helpful instrument to assess these emotional and psychological characteristics.

This study was undertaken to address the difficulties and inconveniences of an electric wheelchair. We focused on improving usability of initially completed products by augmenting the prototypes designed in the previous study. For evaluation of usability, 10 elderly women aged over 65 years, capable of movements and physical activities in daily life, were enrolled as subjects. The experimental method included a subjective satisfaction questionnaire evaluation of the elderly women using the target product, and the observation evaluation was achieved using video recording data, etc. Usability evaluation revealed that the elevating sector requires improvement of intuition through separation of the elevating control panel and the driving control panel. Improvements in the driving sector include corrections of the front wheel mechanism or driving control algorithm, UI, and sudden stop system. Transferring section assessment revealed a necessity to secure structures and add structures that support power. We believe that based on the inconveniences and improvements presented in the usability evaluation, appending the existing prototype with complementary products will improve the quality of life of elderly women with limited mobility.

Sexuality education in the period of adolescents need much care and attention. The programs of sexual education through the Internet are excellent resources for adolescents to gain the information related to their sexual health. And systematic program which is necessary for adolescents to manage their sexual health has been rarely found in Korea. The purpose of this study was to offer valuable database for program design and evaluation on sexual education of middle school students through the Internet. Needs assessment for the information of sexual education on the internet among middle school students were carried out. A questionnaire survey was conducted with respondents of 602 middle school students from January to March in 2002. In the sexual counseling center for middle school students, counseling cases through internet were analyzed and evaluated from October, 2001 to September, 2002, We have selected 16 Sexual educational websites in Seoul confirmed Korean Educational Human Resource. Contents which was illustrated in 16 sexual educational websites were analyzed and evaluated by 12 sexual counselors. Design and evaluation of the program on the internet for sexuality education of adolescences was conducted on the basis of this study results by middle school expert teachers, sexual counselors, sexuality education professionals. Data was statistically analyzed using dBSTAT 4.0 for Windows. The extent and phase of the teaching-learning program of the sexuality education on the internet was seen as follows : 1. We evaluated to need for sexuality education on the internet by middle school student. 2. We assessed the properness of sexuality education curriculum on the internet frequently used by middle school students. 3. We designed teaching strategy and learning program for sexuality education of the middle school students. 4. We developed the assessment method for the teaching-learning program of the sexuality education in adolescences on the internet. Middle school students responded that sexual education through Internet is needed in the order of programs related to acquaintances with opposite sex, Sexual culture and ethics, Sexual health, Reproductive health structure and development, Marriage and family, Psychology of Sexuality, Pregnancy and birth. In the internet counseling, cases on the 'reproductive health structure and development' was ranked as the top. In short we have found the most needs as follows; Meaning of the marriage life and having family, Sexes and Love, Human relation, Sexual Culture.We recommend as follows on the basis of this study results: 1. It is necessary for sexuality education program on the internet to specify according to age and target the specific individual needs. 2. Sexual educators have to employ various educational materials such as flash, cartoon, multimedia in order to provide effective sexuality education. 3. Internet based sex education need to be evaluated regularly through reassessment of the effectiveness of sexuality education for content quality and richness.

One of the words that describe unique features of human beings is "Homo Ludens (Playing Man)". As humans enjoy abundant and prosperous lives and the quality of life is further improved, play is increasingly becoming a central value of human life. As part of play, ocean leisure is getting popular these days, and in turn demands for ocean leisure-related products in Korea, most of which are dependent on foreign markets, are growing. Therefore, it is required that local companies are quick to turn their eyes on the fast developing market. This research aims to help develop a design concept for bodyboard, more suitable for the domestic market, by analyzing products and reflecting customers' needs. The findings of this study are as follows: first, it is desirable that the target of bodyboard in domestic market is young people aged between 14 and 29 and its price ranges from 40,000 to 100,000 won; second, a tube-type bodyboard is appropriate for beaches in Korea mostly with small and gentle waves, as also shown in a survey that over 65% of those surveyed prefer a tube-type bodyboard, and lastly, the CMFF (Color, Material, Form, and Function) strategy was newly developed in this study in order to create new concept bodyboards.
