If the concentration of surfactant reached to any constant point in water, the physical property of the solution is changed rapidly. This is becouse of formation of micelles in water as cohesion. In this study, Dodecylsulfate was used as a raw matrial and the structure of micelles and the process of micellization were explained in term of thermodynamics. The ideal solution theory was also applied to this explanation in the range of dilute concentration. Adsorptivity surface tension and viscosity of surfactant solution contain micelles were also considered in this study.

The purpose of the study was to develop the curriculum of medical welfare based on the perspectives from the disciplines of medicine, nursing and social welfare. The final goal of the study is to enhance the clinical competency of the graduates to effectively deal with the situations required for skills and approaches from both disciplines. The study has been designed to conduct in 3 phases; the first phase to explore the potential employment for the graduates of medical welfare by describing the specific areas which their clinical competency would fit in, the second phase to identify the level of recognition made by students regarding the medical welfare program, the third phase to develop the curriculum of medical welfare according to the student classification. In the first phase of the study, total of 115 questionnaires were sent to the institutions and hospitals specifically selected for their relevancy to the medical welfare program and 53 responses (reply rate 46.1%) were included in the analysis. Most respondents (87%) were familiar to the definition of medical welfare and 77.4% reported that they believe this program would be helpful to do their job. More than 90% of respondents assessed the future of the medical welfare program is rather good. In the second phase of the study, 301 students from the first and second year of Soonchunhyang University received a questionnaire regarding the medical welfare program that has been recently listed in their option for secondary major. Thirty percent of the respondents were aware of the program, and 65% expressed their interests in this program. Majority of the students (86%) considered this program would be helpful to find a job after their graduation, assessing the future of the program as promising. Most respondents (83%) were willing to refer this program to their family and friends. In the third phase, the specific curriculums of medical welfare program were developed according to the background of the potential participants. The first module is for those from social welfare discipline (14 subjects, 35 credits), the second is for those in medicine and nursing disciplines (14 subjects, 40 credits), and the third module is for those with other major (15 subjects, 41 credits). At the completion of each module, the students are allowed to take the exam for Advanced certificate of care worker. The study findings confirmed the need to develop the new approach combined in medicine and social welfare to accomplish the required role of social welfare related to the medical situation. Further studies would be required to evaluate the pilot application of each curriculum module of the medical welfare program as an evidence of practice-oriented education in university setting.

신혜종 순천향대학교 사회과학연구소 2005 순천향 사회과학연구 Vol.10 No.3

There has been increasing number of agencies that provide domestic violence related services since the enactment of the laws on family violence. However, Studies on inter-agency coordination of these agencies repeatedly found that service referrals and information sharing among these agencies are very informal and ineffective. The purpose of this study is to examine problems of inter-agency likage system of domestic violence related services and to find answers to those Problems. The on-lline service networking system that can enhance service referral and information sharing toward a comprehensive domestic violence service delivery system is suggested as one of the answers. The major findings of the study are: 1) survey respondents asserted that difficulties in linking to other agencies occur because they neither have formal agreement on linkage nor understand functions of other agencies; 2) effectiveness of inter-agency coordination is proved by the people who have referred and shared service and information for the victims; 3) most respondents reported the necessity of the on-line service network for the comprehensive service delivery what will be beneficial to the victims of domestic violence; 4) information that they want to share through the on-line network is functions of different agencies, detained information on victims and perpetrators, programs and interventions for them, follow-up results, court order for the perpetrator.

The purpose of this study was to establish a foundation for an effective career planning counseling for students majoring in social welfare. Social welfare is a unique discipline which has many subdivisions and field. Students who are majoring in social welfare needs more delicate career planning counseling where each person can explore and find a career that is suitable and enjoyable for him/her. In this study, the authors conducted an exploratory study of college students on their attitudes on the major and career planning after graduation in Chungnam province. Total of 237 students from three universities which have social welfare major have participated in this study. Since all three universities let students decide their major in the beginning of the second year, freshmen were excluded from this study. The study was done with survey method in which questionnaires were delivered to social welfare departments of participating universities and asked to send the completed ones back to the authors. The students were asked to complete the questionnaire during the class period, The questionnaire was consisted of three major part: demographic information, questions on social welfare major, questions on career planning. After data were collected, 14 cases which didn't answer the third part were omitted from the career planning analysis. Those 14 cases, however, were included in the analysis of sample characteristics. The result of the study was as follows: 1. Students' motivation to choose social welfare as their major was that it seemed to fit with their aptitude and/or interest. When students choose their major, three most influential persons were students themselves, parents, and their senior-year teacher. 2. The general satisfaction regarding their major was fairly high. The reported reason for that was the same as their motivation for choosing social welfare as their major. 3. More than half of the sample has reported that they are interested in direct social work practice. In addition to that welfare for children/adolescents, welfare for infants and toddlers were the most interested social welfare practice fields. 4. Most students wanted careers that are related to their major. The percentage of students who want major-related careers increase as they advance in the academic year. However, career planning of male students was different from that of female students. Male students have tendency to look for careers that are not related to their major Those include entering careers in different fields and starting own businesses. 5. In career planning maturity index, 'Planning' and 'Independence' didn't show statistically significant difference among subgroups. In 'Decisiveness', however, male and seniors reported higher scores than female and sophomore/junior students. This study was concluded with underlying assumption that college career guidance should be done within particular major, so that students can find their career interest and prepare for the future as soon as they learn their aptitude and interest. When they learn about themselves regarding their interest, they can plan their coursework, field instructions, volunteer works according to that. The authors wish that this kind of study would be done with bigger sample size including universities in other areas, so that career planning counselors of major professors could have extensive data to effectively guide the students when they need them.

전이금속 착물의 전자 구조 및 화학적 반응성 (제30보) : trans-[Cr(cyctn)X₂]+(X=F, Cl)의 전자분광학과 리간드장 해석

The electronic d-d spectra of trans-[Cr(cyctn)X₂]^(+) (cyctn=l,5,9,13-tetraazacyclohexadecane; X=F, Cl) complexes have been interpreted in terms of the ligand field theory. The band maxima are fitted with secular determinant for quartet state energy of d^(3) configuration in tetragonal field including configurational but neglecting spin-orbit coupling. A spectral fitting computer program is used to minimize the differences between the calculated and the observed positions for the spin-allowed transition bands. The crystal field parameters are directly related to the normalized spherical harmonic hamiltonians, angular overlap and semiempirical parameters. Values of the various ligand field parameters have been obtained and discussed from the point of view their chemical significances. The results derived from the analysis of the electronic spectra allow us to determine the energy levels of d-orbital and quartet state of trans-[Cr(cyctn)X₂]+ complexes. According to the results of ligand field analysis, it is confirmed that the fluoride ligand is a very strong σ- and π-donor while the chloride has weak σ- and π-donor properties toward chromium(III) ion

This research was undertaken in order to provide a crisis intervention program for the unemployed and their families. A crisis intervention method is necessary in order for the recently unemployed and the family to restore and enhance social functioning that may be impaired by the crisis. Goals for intervention in crisis situation are to alleviate the immediate impact of disruptive stressful events and to help mobilize the psychological capabilities and social resources for coping with the effects of stress adaptively. With those goals in mind, the crisis intervention program for the unemployed and their families was developed through a research conducted on the target population. The program consists of four distinct steps: ① Understanding of current situation; ② Confirmation of the family's love; ③Planning for the problem solving; and ④ Establishing of a support system. In each step, tasks are layed out for the family to accomplish. Even though this program offers 4steps and various tasks to accomplish, it is flexible to apply according to the family's characteristics and the nature of their problems. This program has not been tested for its effectiveness, thus, replications with larger and broader sample of unemployed and their families are required.
