This study has been done in order to help the people understand the cancer patients and provide the basic materials for the care of cancer patients by deeply understanding the living experience of the practice of alternative therapy for cancer patients. Data were collected with several in depth interviews and observations. Collected datas were analyzed by using phenomenological method of study by Giorgi (1970). The trial experience of alternative therapy for cancer patients has been classified into the one of having concerns, following, being infatuated, and coming out by pushing, and the experience of having concerns appeared as the meaning of the limit of modern medicine, despair, loneliness. hope, emotional support. dissolution of the feeling of uneasiness. the feeling of burden of the medical expense, self-treating, the subject of treatment. and indifference while the experience of following appeared as the meaning of blind following, temptation, going outside to look for something, wandering. following unconditionally, advise of the professionals, mistaken belief. self-abandonment, powerlessness. disconnection of dialogue with the medical staff. elevation of immunity, strengthening the physical power, absence of the source of examined information, clinging, self-responsibility. the experience of being infatuated appeared as the meaning of thorough trial. affirmative experience. devotion. diverse efforts, faithful trial. affirmative self-suggestion. change of the style of life. the feeling of burden of expense, being envious, bitter feeling toward the family, considering family, family discords, and difficulty of enforcement. The experience of coming out by pushing appeared as the meaning of waiting. self-reflection. maintaining the distance. cutting attachment, throwing the greed away, coming out by pushing. being thoughtful. accepting disease. individual difference of physical quality, and ambivalence. But they return to the experience of being concerned all over again in case of recurrence or metastasis of the disease even though they come out of such stage, and they always have ambivalence even in the condition with no recurrence and metastasis. In conclusion, the trial of alternative therapy for cancer patients could be explained as the adaptive behavior to the disease which is difficult to be cured. the cancer. The cancer patients are exposed to the side effects and harm without the examined information resources. Therefore the nurse should well aware of the alternative therapy and be able to do the appropriative management through the open communication with the patients who are under the trial of alternative therapy.

Purpose: Heat transfer analysis of recently developed 'slim type double-skin system window' were presented. This window system is designed for curtain wall type façade that main energy loss factor of recent elegant buildings. And the double skin system is the dual window system integrated with inner shading component, enclosed gap space made by two windows when both windows were closed and shading component effectively reflect and terminate solar radiation from outdoor. Usually double-skin system requires much more space than normal window systems but this development has limited by 270mm, facilitated for curtain wall façade buildings. In this study, we estimated thermophysical phenomena of our double-skin curtain wall system window with solar load conditions at the summer season. Method: A fully 3-Dimentional analysis adopted for flow and convective and radiative heat transfer. The commercial CFD package were used to model the surface to surface radiation for opaque solid region of windows' frame, transparent glass, fluid region at inside of double-skin and indoor/outdoor environments. Result: Steep angle of solar incident occur at solar summer conditions. And this steep solar ray cause direct heat absorption from outside of frame surface rather than transmitted through the glass. Moreover, reflection effect of shading unit inside at the double-skin window system was nearly disappeared because of solar incident angle. With this circumstances, double-skin window system effectively cuts the heat transfer from outdoor to indoor due to separation of air space between outdoor and indoor with inner space of double-skin window system.

A catadioptric optical system produces images by refraction and reflection. To improve the image quality, the shape of the secondary mirror supporters should be determined to ensure that the centering error and tilt of secondary mirror are very small, and the main mirror receives the maximum amount of light. Furthermore, random acceleration vibration has a severe effect on the optical system for observation reconnaissance. In order to obtain the best design under these circumstances, the volume of the secondary mirror supporter must be minimized while satisfying the constraints expressed in standard deviations of the centering error and tilt. It is difficult to analytically calculate the design sensitivities of the standard deviations, because they are statistically defined. Hence, after their second-order regression equations were determined using a response surface methodology, an optimal geometric design was obtained. As a result, it was found that the method proposed in this paper, which included a random vibration analysis, was effective in obtaining the optimal design for a secondary mirror supporter with robustness.

Currently, the method of user-follwoing in intelligent cooperative robots usually based in vision system and using Lidar is common and have excellent performance. But in the closed space of Corona 19, which spread worldwide in 2020, robots for cooperation with medical staff were insignificant. This is because Medical staff are all wearing protective clothing to prevent virus infection, which is not easy to apply with existing research techniques. Therefore, in order to solve these problems in this paper, the ultrasonic sensor is separated from the transmitting and receiving parts, and based on this, this paper propose that estimating the user's position and can actively follow and cooperate with people. However, the ultrasonic sensors were partially applied by improving the Median filter in order to reduce the error caused by the short circuit in communication between hard reflection and the number of light reflections, and the operation technology was improved by applying the curvature trajectory for smooth operation in a small area. Median filter reduced the error of degree and distance by 70%, vehicle running stability was verified through the training course such as 'S' and '8' in the result.

1. Based upon an fertilizer experiment done in a farmer's field, with a medium maturity variety, Jinheung, (in 1969) a method of determination of nitrogen to be additionally given, at tillering and reproductive stages was studied. In this experiment, four kilograms of nitrogen per 0.1 ha was applied as basal dressing to all experimental treatments at transplanting time. 2. The application of nitrogen at the reproductive stage of paddy increased the yield remarkably and cut down the amount of nitrogen to be given at the tillering stage. The yield of paddy, 670kg/0.1 ha obtained by the application of 6.82kg N/0.1 ha at the reproductive stage far exceeded the yield, 644kg/0.1ha obtained when over 8kg N/0.1ha of N is applied at tillering stage alone. This emphasizes the importance of nitrogen top dressing at the reproductive stage. 3. As the amount of nitrogen to be given at both stages, reproductive and tillering, would be the reflection of soil fertility of the field, a correlative study between the amount of nitrogen to be given at both stages and soil analysis is suggested to be undertaken. 4. A study on the relationship between the amount of fertilizer to be given at stages different growth and yield components is suggested to be undertaken for the purpose of establishing a better fertilizer use technique.

Background: It is known to reduce the mortality when glutamine is supplied to patients during the surgery or in intensive care unit through intravenous nutrition supply. The purpose of this study is to establish the appropriate basis for use of glutamine and guidelines of nutrition supply for critically ill patients in the hospital by examining the clinical effects of administration of glutamine with subjects of elderly critically ill patients receiving intravenous nutrition in one hospital in Korea. Method: Among elderly patients with age of 60 or more hospitalized in Yeuido St. Mary's Hospital from August 2012 to July 2013, those who stayed in the intensive care unit for more than a week and received TPN (Total Parenteral Nutrition) for more than 3 days during staying in the intensive care unit were classified to a test group using glutamine and a control group without glutamine. Duration of use of mechanical ventilator, duration of hospitalization, occurrence of infectious disease and death were compared between two groups. We would like to identify the clinical test figures affected by the use of glutamine by examining changes in SCr, Total Protein, Albumin, AST, ALT, TB, DB and GFR at the time of admission and discharge. Results: At the time of admission to intensive care unit, gender, physical measurement information and clinical test figures did not show any significant difference between 72 subjects in a test group and 24 subjects in a control group. Thus, two groups began in the same condition. There were no significant difference in duration of hospitalization, duration of intensive care unit, use of mechanical ventilator, occurrence of infectious disease and death. As the results of statistical analysis of the average changes of clinical test figures at the time of admission and discharge of intensive care unit, SCr and GFR were significantly changed in the test group. GFR was significantly changed in a control group. As the result of analysis of the clinical test figures at the time of discharge with reflection of average changes after clinical test figures were corrected at the time of admission of intensive care unit, TB and GFR were significantly increased in a test group compared with those in a control group. Other clinical test figures were not significantly changed. Conclusion: If glutamine is administered to critically ill patients over age 60 receiving TPN and careful monitoring for total bilirubin is made in the future, it is expected to give the positive effect on renal function andminimize the side effect of arise in total bilirubin.

This study was conducted to investigate the perception of teaching consulting and dietary education of Home Economics teachers. The subjects consisted of 139 Home Economics teachers in Korea. The perceptions of Home Economics teachers on their teaching class were as follows: the teachers who had a lot of psychological burden on their open classes, 62.6%; who were satisfied with their teaching, 29.5%; who had been teaching consulting, 40.3%; consulting is needed in order to improve the quality of instruction, 46.8%; who wanted to receive teaching consulting, 46.1%. who wanted to receive teaching consulting excellent colleagues, 76.3%. The most of the Home Economics teachers had a positive attitude on the teaching consulting. The perceptions of teaching strategies of dietary teaching classes were as follows: using audio-visual materials for students concentrate, 47.5%; observing the students reactions and feedback for individual variation, 73.4%; descriptive class for main teaching method, 58.3%. The difficulties of teaching dietary class were as follows: total mean, 2.60/5.00; considering individual differences, 3.26; involving students in activities, 3.11; selection of teaching media, 2.88; production of media, 2.88; planning teacher and student activities, 2.85. Home Economics teachers have to lead dietary education in society and schools but they feel a lot of psychological burden on opening teaching class. Therefore Home Economics teachers are recommended to devote consistent efforts to strengthen teaching ability through the analysis of teaching ability, teaching reflection, consulting and actual performance of self-supervision.

The National Museum of Korea conducted conservation treatmenton the armor in its collection for the purposes of public display and appropriate preservation. This was preceded by a literature study on the types and features of the armor in order to collect basic data for secure and accurate conservation treatment. The literature study found that during the Joseon dynasty, armor was named in reflection of precise details including the color, material, status of the wearer, and even the certain parts of a suit of armor. In general, the name of armor includes the details in the order of color, underlying textile, and scale material (e.g., iron, leather). The former part of the name presents the features of the garment and the latter part refers to the material of the scales or the status of the wearer. The study also found that main materials used in armor include textiles, leather, and metal, and armor can be classified by the materials of the scales-e.g., metal armor (鐵甲), leather armor (皮甲), paper armor (紙甲), paper-and-fabric armor (淹心甲), silk armor (緞甲). Joseon-period armor can also be classified into four types according to its structure and the method of wearing, and overcoat(袍)-style armor was the most widely used in the period following the Japanese Invasion of Joseon (1592-1598) through the late nineteenth~early twentieth century. Overcoat-style armor was commonly worn by infantry, and the four examples of armor with leather scales at the National Museum of Korea belong to this category.

The purpose of this study was to analyze various factors that influence the academic life of students through a theoretical review. As a result of the analysis, sub-factors were derived to diagnose the factors. From the study's findings, principles and models for developing learning status diagnosis tools were designed. The study first, based upon the competencies of university students, university life, students' low academic achievement, and academic probation studies, confirmed what factors affect student learning and from them derived a set of sub-factors. The setting dimension was divided into psychology, learning, and career factors, while also including a factor of faith for Christian university students. Next, in the draft model, sub-factors were constructed for each factor: faith maturity and faith training in the faith factor, positive thinking, emotion regulation, and self-esteem in the psychology factor, self-directed learning ability, learning motivation, and learning strategies in the learning factor, and career reflection, career exploration, career management, and career barriers in the career factor. By using the Delphi method, the final model of learning status diagnosis was confirmed. As a result, we completed the model comprised of nine sub-factors in four parts. A follow-up study should be conducted that examines learning status diagnosis tools development research.
