Objective: The purpose of this study is to evaluate integral seat desk used in universities through comparison of real dimension values of the desk with KS/ISO standard and questionnaire survey. Background: School furniture that helps students sit comfortably for longer periods of time and allows for better concentration on learning is important. However, seat and desk have been generally designed based on the industry practice rather than user's anthropometry, and seats and desks used in universities of Korea have not been ergonomically evaluated. Method: Real 13 dimensions of the desk used in K University were measured using tape measure and inclinometer, and the dimension values were compared to the KS standard of desk and chair for lecture room (KS G 4210) and ergonomic design principles found in relevant references. Subjective appropriacies and preference for the desk were investigated based on questionnaire survey, in which 121 (male: 91, female: 30) college students participated. Results: Several dimensions for the desk and chair investigated except desk depth and width, leg room width, seat width have not met the KS standard, but all dimensions satisfied ergonomic design principles available in references. The questionnaire survey revealed that appropriacies for desk surface size, seat pan depth, seat pan cushion and backrest curvature were under middle point of 3.0, and that those for the other dimensions showed higher scores exceeding 3.0. Conclusion: The integral seat desk widely used in universities showed some design problems in terms of standards of KS G 2010 and KS G 4210, and ergonomic design principles. Compared to the general desk with separated desk and seat, subjective preference on the integral seat desk was low. Application: This would be used as a valuable guideline when designing or choosing new integral seat desk with high satisfaction of students.

The purpose of this study is to present a simplified model of predicted mean vote (PMV) using multiple regression analysis. We performed the experiments and the numerical calculations in the lecture room during summer and winter to simplify PMV. And the multiple regression analysis on PMV was conducted to estimate the contribution of independent variables toward PMV. From the multiple regression analysis, we found that the effect of independent variables on PMV followed in order, clo value>air temperatur>air velocity>mean radiant temperature>relative humidity. And the simplified PMV was proposed through a few assumptions and then was compared with original PMV. They had a good agreement with each other. Additionally, we compared the simplified PMV with EDT. We expected that the simplified PMV can be more useful than EDT to evaluate the thermal comfort in the place, where radiation is dominant. But the comfort range of the simplified PMV should be adjusted to predict the exact thermal comfort in the future.

Department store has actively expanded cultural center services by providing a series of educational courses in order to increase customer visits, enhance customer satisfaction, and ultimately increase sales. In this study, cultural center members' shopping behaviors and image building of the department store were explored through focus group interviews. Results generated from a total of 7 focus group interviews with female cultural center members in their 30's through 60's are as follows. First, the consumer group who attends courses for their own purpose is 45 to 55 year-old female customers who are actively involved in consumption at the department store for their own clothing, food and restaurant. They are not often engaged in impulsive either group shopping for clothing. They are satisfied with class quality compared to low tuition whereas dissatisfied with busy schedule of a lecture room and lack of special discount benefits for members. Second, the other consumer group who attends courses for their children is consumers in their 30's. They are charged in shopping for clothing for their husbands, children, and themselves. They are suffering time poverty due to nurturing their children, therefore, they want to shop more in the department store on the day of class. However, expensive kids-care facilities are barriers to do it. Convenience, familiarity and center of culture are important images of the department store, developed through frequent visits of these customers. Eight implications for marketing strategies were generated based on study results.

Purpose: This study was done to examine the effect of direct practice of newborn health assessment on nursing student's clinical competence and self-efficacy and to propose effective strategies for clinical education on newborn care. Methods: Design was a nonequivalent control group quasi-experimental study. The direct practice program was composed of a lecture, demonstration, drill and feedback using a manikin, and repeated direct practice regarding newborn health assessment. Participants were 65 student nurses taking the pediatric nursing practicum in the nursery room at M hospital. The experimental group (n=33) participated in the direct practice program for newborn health assessment and the control group (n=32) received the traditional practice method. Nursing clinical competence was assessed by two nurse investigators and structured questionnaires were used to measure self-efficacy. Results: The experimental group's clinical competence was significantly higher than that of the control group (t=-4.82, p=.000). However no significant difference was found between the two groups for self-efficacy (t=1.264, p=.211). Conclusion: These findings indicate that the direct practice program is effective in improving nursing student's clinical competence, but it was not effective in increasing self-efficacy. Direct practice in various clinical education settings is recommended and longitudinal effects be evaluated.

When you present a medical scientific paper or give a lecture in English, It is important to visit your presentation room in advance to gain familiarity with the controls and the computer. You can check how to use the mouse or laser pointer and determine where the microphones are. You should meet the Chairman and introduce yourself. You may ask the Chairman any questions you have. I am confident this strategy will work for beginners because they are usually nervous before their presentations. Most Chairmen prepare one or two questions for the presenters to stimulate discussion. Speaking with the Chairman also allows you to determine the type of English that he or she speaks (i.e., French-English, Spanish-English, and British-English). You need to be comfortable with the Chairman's English before the presentation because the Chairman will repeat the questions for you when you do not understand a question from the audience. Although I have given a number of lectures and moderated many scientific sessions and symposiums in English over the past 20 years, it is still difficult and stressful for me to do these in English because English is not my first language. To overcome the problems, I have written down the questions and useful English expressions that I have received during or after my presentation because I found them helpful for my next presentation. I hope the examples will be of great help to you.

Purpose: This study was conducted to develop Web-based multimedia contents for supporting student nurses' clinical practice on critical care, and to evaluate learners' responses. Methods: Based on the steps of Assessment, Design, Development, Implementation, & Evaluation(ADDIE) model, a total of 13 self-directed learning modules including live lectures and real video clips were developed through faculty collaboration of nine nursing colleges in Gwangju and Chonnam province. The finally developed multimedia contents were published on the Web of the learning management system at a local e-learning center. Results: The Web contents were evaluated after self-learning by 81 junior college nursing students who were encouraged to study it at their own pace during their two-week clinical practice at a medical or surgical intensive care unit of a university hospital and two hospitals. The knowledge (t = -27.66, p < .001) and self-evaluated clinical performance level(t = 7.54, p < .001) were significantly increased after learning of the Web contents and clinical practice, and satisfaction level that measured post-test only was 4.0 out of 5 point. Conclusion: The use of Web contents for critical care need to be extended as a complimentary material in a class room lecture or clinical practice of students to increase their self-learning ability and understandings of clinical knowledge and situation.

A set of candela distribution curves(CDCs) were generated for a fiber optic dish daylighting system by Photopia under clear sky conditions at different solar altitudes. The candela distribution curves were then exported to Radiance for photometric analysis of a windowless lecture room. Observations were made on the Radiance rendered illuminance images, which provided photo realistic scenes varying with solar altitudes. If no tracking error were assumed, the daylight collection efficiency of the system remained at a constant value of 68.4% during its operation. Higher the solar altitude angle, greater in photometric quantities were observed, which are represented by candela(cd) and total lumens(lm). In all cases considered, however, the angle of light distribution remained fixed reflecting the solar tracking feature of the system. The illuminance uniformity on the workplane lingered around 0.12, which is quite low. This is quite a contrast to its average value of 0.68 of the $2.7m^2$ area directly below the terminal device (diffuser) of the system. The maximum illuminance of 1,340lux was obtained at a solar altitude of 80 degrees.

The Villa Mairea (1937-39) designed by Alvar Aalto (1898-1976) has been studied by many researchers from various viewpoints. However, few studies have devoted their attention to the major issue raised by Aalto at the Yale University lecture and "Mairea" article in arkitekten in 1939. The issue is to fuse art with life in the living room with mobile partition walls that can function both as art exhibition walls and as art storage cabinets at the same time. Through this device, he maintained, the client can change displayed pictures easily according to the situation and so "painting and everyday life can evolve in a more direct manner." This paper argues that Aalto's concept originated from Japanese 'tokonoma' in Tetsuro Yoshida's Das japanische Wohnhaus (1935), which he referred to during the project. Differently from other Japanese features in the house, this tokonoma idea is more than formal, but more decisive than passing in driving the plan. And, whether coincidently or not, his idea exactly corresponds to Japanese aesthetes' and critics' own interpretation of the tononoma as the symbolic centre of Japanese people's everyday life. More importantly, however, this art display concept discloses secret strata of modern architecture during the time when the petrified rationalism was still at its power Even through the tokonoma motif alone, we see diverse trails in modern architecture: fusion of the East and the West, fusion of the traditional and the modern, to say nothing of fusion of art with life.

Objectives: This study was performed to examined the effectiveness evaluation of peer education program on smoking prevention and cessation for elementary school students. Methods: Data were collected from 60 students in a rural area through self-administrated questionnaires. Child-leaders participated the peer education program to assist their friend, parent, and adult in community to quit the smoking for 4 weeks. Results and Conclusions: Major conclusions were as follows : 1. The peer education program on smoking prevention and cessation for elementary school students was reinforce to increasing the tobacco knowledge and the cessation skill, learning the communication skill, and improving the empowerment. 2. Image of tobacco, intention of smoking in future, recommendation for smoking cessation, pro of smoking. con of smoking, and level of assert in post-test were higher than those in pre-test. 3. There were significant differences in image of tobacco, con of smoking, and level of assert by grade between the pre-test and the post-test of peer education program. But intention of smoking in future, recommendation for smoking cessation, and pro of smoking were not related to effectiveness of peer education program. 4. Child-leaders for smoking prevention and cessation performed the their task to 1.4 persons per student. 5. Participating students were satisfied with the contents of program, the usefulness of educational materials, and preference of parents, but they were not satisfied with the usefulness of task note, learning time, and lecture room.
