Although heat treatment is a process of great technological importance in order to obtain desired mechanical properties such as hardness, the process was required a tedious and expensive experimentation to specify the process parameters. Consequently, the availability of reliable and efficient numerical simulation program would enable easy specification of process parameters to achieve desired microstructure and mechanical properties without defects like crack and distortion. In present work, the developed numerical simulation program could predict distributions of microstructure and thermal stress in steels under different cooling conditions. The computer program is based on the finite difference method for temperature analysis and microstructural changes and the finite element method for thermal stress analysis. Multi-phase decomposition model was used for description of diffusional austenite decompositions in low alloy steels during cooling after austenitization. The model predicts the progress of ferrite, pearlite, and bainite transformations simultaneously during quenching and estimates the amount of martensite also by using Koistinen and Marburger equation. To verify the developed program, the calculated results are compared with experimental ones of casting product. Based on these results, newly designed heat treatment process is proposed and it was proved to be effective for industry.

This study evaluated the effectiveness of affected-based program in changing the nutrition attitudes and behavior of a group of low-income housewives in a urban area near industrial complex. using pre- post- and one month retention test measures of nutrition attitudes knowledge and nutrition behavior. The sample consisted of treatment group(n=58) and control group(n=68, 66 or 61) The treatment group participated in a four-week nutrition course of eight hours offered by faculty members of department of Food and Nutition in Han Nam University. At the conclusion of the program the respondents had improved nutrition attitudes increa-sed nutrition knowledge and improved dietary diversity and dietary quality scores. Nutrition attitude scores rose significnatly from the pretest to post-test for the treatment group only However this improvement was not maintained one month after education. Nutrition know-ledge score of the treatment group increased significnatly from the pretest to posttest and pretest to retention test. Nutrition behavior was measured by food practice dietary diversity and dietary quality scores, The mean food practice score dietary diversity and dietary quality scores were signifi-cantly increased from pretest to posttest for the treatment group. Only dietary diversity scores was maintained from posttest for the retention test for the treatment group. There was a good correlation between nutrition knowlege and attitude scores at the pretest. However no significant corrlation was found between nutrition knowledge and attitude scores at the posttest. At the pretest nutrition knowledge or attitude and behavior were not correlated bu there were significant correations between nutrition knowledge or attitude and behavior at the posttest. It was concluded that a four-week nutrition education program of eight hours duration for the target people can lead to ac hange in dietary behaviors as well as nutrition knowledge and attitude.

This study explored the effectiveness of a hierarchical treatment of aphasic perseveration (TAP) program in a Korean client with transcortical sensory aphasia. The subject with 52% perserveration score (Korean version of Boston Naming Test : K-BNT) was 44 year-old female with MCA (Middle cerebral artery) infarction. The experimental design used was an alternating treatment design with the hierarchical TAP and conventional audio-visual stimulation. The frequency of occurrence of perseverative behaviors and correct response in naming performance were analyzed and compared. It was claimed that the hierarchical TAP was more effective in naming performance than conventional audio-visual stimulation in terms of correct naming response. The frequency of occurrence of perseverative behaviors was lower in hierarchical TAP but the difference was relatively small. Unlike in English, sentence completion task was no longer stimulable while unison speech was very stimulable among the specific strategies of TAP program in Korean. Therefore, it could be said that TAP is language-dependent.

The outbreak of foot and mouth disease in November 2010 raised many social, economic and environmental issues and water contaminations by leachate from carcass disposal sites particularly emerged as a serious concern. In oder to efficiently handle these problems, a critical method is required to transport leachate to livestock manure and sewage treatment plants and purify it. This study aims to present the best applicable method to transport leachate from carcass disposal sites into livestock manure and sewage treatment facilities. We investigated the biological and chemical characteristics such as BOD, COD, SS, TN, TP and Total coliforms. Current conjugated treatments in livestock manure and sewage treatment plants was studied by surveying the operations of those facilities. The NIER-MASS(National Institute of Environmental Research - Mass Balance Evaluation System of Sewage Treatment Facilities) program was applied to present the best conjugated treatment method through estimating the maximum daily load to meet the water quality standards in effluent.

This study examined the effects of gender, parental support and treatment type on the treatment outcome of adolescent substance abusers. Outcome variable was the successful graduation (or drop) from an Intensive Adolescent Outpatient Program. Adolescents with their parents' support were treated in one of three treatment models (2-weeks Inpatient plus 6 week Intensive Croup-Oriented Outpatient, 8-weeks Intensive Croup-Oriented Outpatient, and 8-weeks Individual-Family Therapy) within a private hospital-affiliated treatment center by managed care practice allowing their own choice (non-random natural assignments). Several hypotheses were tested for main effects by the Log-Linear Analyses for a multi-dimensional contingency table with 440 adolescents (284 boys and 156 girls treated during 1992-l997) from middle-class families with private health insurances. The following results were found. Odds of graduating versus dropping out of the treatment program among : (1) girls were 1.7 times higher than those among boys; (2) adolescents with two-parent were 2.2 times higher than those among adolescents with one-parent ; (3) adolescents with Inpatient plus Outpatient was 1.7 times higher than that of those with Outpatient; (4) adolescents with Individual-Family Therapy was 2.3 times higher than that of those with Outpatient Model. There was no statistically significant outcome difference between the Individual-Family Therapy and the Inpatient plus Outpatient. Implications from the results were discussed. Suggestions were made to improve the treatment components in the areas of gender sensitivity, securing more parental support, alternatives for separation from peer group and integrating new peer groups, and flexibility for the unique needs of individual family. Also, some research questions for future studies were suggested.

A 10-year-old spayed female Yorkshire terrier dog with a history of pleural effusion and dyspnea for a week was referred to the Veterinary Teaching Hospital. Radiography revealed pulmonary edema and pleural effusion. A mass infiltrating the right atrial lumen and especially the supra-tricuspid valve was identified with echocardiography. The mass was diagnosed as intracardiac neoplasia. Symptomatic treatment was prescribed to alleviate the symptoms of heart failure. Despite symptomatic treatment, the patient died a few days later. After obtaining consent from the owner, necropsy and histopathological evaluation were performed. The result was consistent with cardiac leiomyoma, and the diagnosis was confirmed by immunohistochemical staining. To the authors' knowledge, this case is the first report of intracardiac leiomyoma in a dog in Korea.
