We have studied on welding dissimilar materials of Carbon steel SCP1-S by using laser beam. In this research we have performed some experiments to know the possibility of welding dissimilar materials using laser beam and magnetic fields by adjusting the power output of 35W laser. Other conditions of the experiments were as follows : the welding speed was varied in the range 10 m/min nitrogen gas was used as shield gas, the flow value of shield gas was ranged 10 L/min. In order to ascertain of the welded surface, we have done the tensile strength testing, the hardness testing and the microscope observation. As a result, we have found that tensile strength was the highest at the condition of the welding speed of 10mm/s, the flow value of 10 L/min, the gap of two materials 0, and the use of nitrogen gas. Above testings have also showed that the tensile strength was generally satisfactory since the penetration of welding was almost complete due to the thinness of the materials. In addition, the formation of the welded area was excellent when it had the highest tensile strength.

There is a need to enlarge the mother glass substrate in OLED to raise its productivity and to realize OLED TV. On the other hand, some difficulties may arise regarding the deflection of a large glass substrate during its handling operation due to its thinness $(0.5\sim0.7t)$, which is not even enough to allow it to stand its own mass. This thesis proposes a conceptual plan for the application of the clamping- and bending-end conditions to the glass substrate handler. To verify proposed plan, the non-contact 3 dimensional measuring instrument is developed. The composition of the 3 dimensional measuring instrument measures shape of the product using X-Y stage robot and laser distance sensor. X-Y stage robot and laser distance sensor are controlled by LabVIEW language. To calibrate measuring instrument, the direction conversion of the Euler angle was used. In order to confirm deflection of the glass substrate, the experiment was carried out at the bending end boundary condition and the proposed effect was verified.

This study was conducted to provide information about weight control behavior in adolescent females. To explain the behavior intention of dieting, conceptual framework based on "Social Support, Control and the Stress Process Model" and "Theory of Reasoned Action" was used. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done using mean, correlation and multiple regression analysis with the SAS computer program. A society preoccupied with thinness gives a burden to women, and this burden may stress dissatisfaction with body image. Social perception of ideal body image except parents' perception, and salient others'perception, and salient others' expectation of subjects' body image except parents' expectation, were much thinner than normal figures in this study. The influencing factors for behavior intention of dieting of the subjects were perceived stress and attitude toward diet behavior, especially beliefs of behavioral outcome. Influencing factors related to perceived stress-that is dissatisfaction of body image-were current figure, social perception of body image, effect of mass communication and others' estimation of subjects' body image with self-comparison with others, in order.th others, in order.

Thinness has become a symbol for beauty acceptance and competence for women in our society especially for young college women. Relatively little is known about characteristics of women who are dissatisfied with their shape or weight and who are interested in performing weight control program. Four hundred college women in Seoul and Kyunggi-Do area were surveyed from November to December 1992 to investigate the relationship between the concern about weight control and various aspects of food related behaviors. The purpose of this research was to investigate the relationship between the weight concerns of college women and their aspects of several eating behaviors. Self-developed questionnaire was used after validity test. The results were as follows: 1) The average height weight and BMI value of subjects were 160$\pm$4.5cm 51.02kg and 19.86$\pm$4.5 respectively. 2) The 49% of subjects were highly concerned about weight control(high interest group) and 39% were moderate concerned(moderate interest group). 3) The average BMI and weight change per year were significantly higher in the high interest group than other groups. 4) The score of nutrition knowledge was also higher in the high interest group, 5) There were no significant differences among groups in the meal frequencies. and amount of nutrients intake. 6) The signs of eating trouble were found in subjects 59.0% of subjects felt feareness about weight gain after consumption of large amount of food. 7) The ratio of CPF was 64:14:22 and nutrient adquacy ratio(NAR) of energy was 0.94 NAR of Fe was 0.84 the other NAR of nutrient over 1.0.

Cold-formed steel structures are increasingly attractive due to their benefits of good mechanical performance and constructional advantages. However, this type of construction is still not fully exploited as a result of the acknowledged difficulties involved in forming construction-efficient and cost-effective connections. Furthermore, there is a lack of information on the structural behavior of the cold-formed steel connections. In this study, the research on various cold-formed steel connections was comprehensively reviewed from both fundamental and structural points of view, based on the available experimental and analytical data. It reveals that the current design codes and guidelines for cold-formed steel connections tend to focus more on the individual bearing capacity of the fasteners rather than the overall structural behavior of the connections. Significant future work remains to be conducted on the structural performance of cold-formed steel connection. In addition, extensive previous research has been carried out to propose and evaluate an economical and efficient connection system that is obtained from the conventional connecting techniques used in the hot-rolled industry. These connecting techniques may not be suitable, however, as they have been adopted from hot-rolled steel portal frames due to the thinness of the sheet in cold-formed steels. The review demonstrates that with the increasing demand for cold-formed steel constructions throughout the world, it is crucial to develop an efficient connection system that can be prefabricated and easily assembled on site.

Purpose: The purpose of this study was to develop the day hospital program for Korean eating disorders patients and to examine the effect of the day hospital program on improving frequency of binging and purging, eating disorders symptoms, self-esteem, and depression. Method: The subjects were 24 binge eaters visited at eating disorders clinic 'M'. They participated in a modified day hospital program based on the Toronto Day Hospital Program. All subjects completed the Eating Disorders Inventory(EDI)-2, Rosenberg Self-Eesteem Scale, Beck Depression Inventory(BDI) at pre and post intervention, and recorded daily food records. Results: In paired t-test analysis, frequency of binging and purging, self-esteem, depression, and 11 sub-scales of EDI-2(drive for thinness, bulimia, body dissatisfaction, ineffectiveness, interoceptive awareness, perfectionism, interpersonal distrust, maturity fear, asceticism, impulse regulation, social insecurity) were significantly improved after treatment. Conclusion: The results of this study suggest that the day hospital program for Korean eating disorders patients may be an effective initial approach to overcoming various eating disorders symptoms. Further studies should investigate longer term outcome data using a larger sample.

Objectives: Despite the importance of Non-pharmacological interventions for Eating Disorders, no meta-analysis providing definite conclusions in this field has been reported. The purpose of the this study was to conduct meta-analysis of Non-pharmacological interventions for the improvement of eating disorders. Methods: We searched the Koreamed, KISTI, KMBASE, RISS and KISS and so on up to October 2017 using search terms such as ((Eating disorders OR anorexia OR binge) AND (Mediation OR program OR treatment OR therapy OR technique)) in Korean. Results: Initial searches yielded 602 citations. Of these results, seven met selection criteria. Interventions reduced the risk of binge eating disorder (standardised mean difference [SMD] -2.133, 95% CI -3.107~-1.159). Interventions reduced drive for leanness (-1.857, -3.143~-0.571), body dissatisfaction (-1.357, -2.238~-0.477), depression (-0.745, -1.298~-0.192), but not physical function (0.191, -0.089~0.471). Conclusions: The results from this study indicate that Non-pharmacological Interventions may help Eating disorders' binge eating, drive for thinness, body dissatisfaction, depression. However, larger-scale studies are needed to confirm this conclusion.

Skin-compatible electronics have evolved to achieve both conformality and stretchability for stable contact with deformable biological skin. While existing research has largely concentrated on alternative materials, the potential of Parylene-based thin-film electrodes for stretchable on-skin applications remains relatively untapped. This study proposes an engineering strategy to achieve stretchability using the Parylene thin-film electrode. Unlike the conventional Parylene thin-film electrode, we introduce morphological adaptability via controlled microscale slits in the Parylene electrode structure. The slits-containing device enables unprecedented stretchability while maintaining critical electrical insulation properties during mechanical deformation. Finally, the demonstration on human skin shows the mechanical adaptability of these Parylene-based bioelectrodes while their electrical characteristics remain stable during various stretching conditions. Owing to the ultra-thinness of the Parylene coating, the wearable bioelectrode not only achieves stretchability but also conforms to the skin. Our findings broaden the practical use of Parylene thin-film bioelectrodes.
