The research aims at providing data needed for planning the lighting of a study room by comparing the lighting environments of study rooms for urban and rural juveniles. The subject of the research was 300 students in middle schools in Daegu and Checngdo-gun, Gyeongsangbuk-do (Daegu 150 houses and Cheongdo 150 houses), and their study rooms were examined. The following is the result of the research. First, rural students stayed more time in their study room than urban students. The task that rural students (studying) and urban students (studying and using computer) all did in their study room was mainly visual work Second, although the sizes of rural study rooms were bigger than those of urban study rooms, urban study rooms had more light sources than rural study rooms. In the rate that of having a task lighting, the city(87.1[%]) was higher than the country (45.7[%]). However, the rate of using a task lighting was lot high in both the city and the country. Third, the result that compared the average values of illuminations on desk planes was that the average value of the city was 3.4 times higher than that of the country. Also, the average value of the country did not meet the standard illumination of Korean industrial standards (KS). In particular, it did not reach the lowest standard. The result is related with that only 52[%] of students who had a task lighting used it. Finally, the satisfaction of lighting environment in the city was generally higher than the country. Especially, although the country had a low illumination, the user showed a high satisfaction. It indicates that people living in the country need to understand about the needs of illumination.

Objectives : This study was conducted to examine the clinical effects of thread embedding acupuncture on lumbar herniated intervertebral disc patients. Methods : This is a retrospective study based on clinical charts. Despite the treatments of acupuncture, pharmacopuncture, herbal medicine, and physical therapy during admission period, 10 lumbar herniated intervertebral disc patients who had shown few improvements in their symptoms were selected as subjects. Thread embedding acupuncture was conducted to reduce patient pain. Patient progress was categorized into three periods based on when the embedding procedure performed. Verbal numeric rating scale (VNRS), Oswestry disability index (ODI), and a 5 step evaluation scale for satisfaction were used to analyze the outcome. Results : Regarding comparison of VNRS improvement rate, both 3 and 6 days after embedding progress showed significant difference compared to before embedding progress. ODI improvement rate showed significant difference only 6 days after embedding progress. Patients' satisfaction with treatment had increased by several degrees. Conclusion : Thread embedding acupuncture for lumbar herniated intervertebral disc patients may be effective in reducing pain and improving their quality of life.

Purpose: Breast cancer is second most common cancer in women. Almost of patients with breast cancer treated with mastectomy undergoes breast reconstruction. Nipple reconstruction is an important step in breast reconstruction. Many surgeons have investigated of nipple reconstruction using the flap technique after breast reconstruction with the autologous tissue. The objective of this study is to evaluate the results of nipple reconstruction using the C - V flap technique after breast reconstruction with the only breast expander. Methods: From April 2006 to May 2008, the authors treated 17 patients of nipple reconstruction using C - V flap technique, who were received breast reconstruction with the only breast expander. We have predicted decrease of the size of reconstructed nipple and designed flap a little larger than wanted nipple size. Nipple splint was applied for 4 - 6 months for minimizing decrease of the size of reconstructed nipple. The diameter and height of the reconstructed nipple were measured and patient's satisfaction score was assessed. Results: Mean follow-up duration was 12.5 months. Among the 17 patients, the average absorption rate by height of nipple was 47.0%. Partial necrosis was noted in 1 case, and treated well with conservative management. There was no other significant complications noted. Patient's satisfactory score was assessed by the height, design and location of the nipple. The average of satisfaction score was 85%, 68%, 62% and total average was 83%. Conclusion: The authors experienced 17 patients of nipple reconstruction using the C - V flap technique after breast reconstruction with the only breast expander. The absorption rate of the size of the nipple, complications and patient's satisfactory score of this study were similar to those of nipple reconstruction after breast reconstruction with the autologous tissue. It is expected that nipple reconstruction after breast reconstruction with the only breast expander is safe and reliable. It is considered that a long - term study is necessary.

The central government in Korea has pursued a policy to privatize municipal solid waste treatment facilities in order to enhance the effectiveness of public financial management in recent years. To understand the intentions of local governments on this policy, the survey with questionnaires on 37 out of 256 local governments was made in October, 2007. The results were analyzed and compared in 6 classified policy areas. The results showed that local government had enough financial status to operate the facilities with proper services and had the opinion with positive management in finance with increasing rate of prospective views. Among the facilities operated by local governments, the satisfaction levels for landfill(46.2%) and incineration(40.0%) were relatively higher. However those for recycling and food waste resource facilities were not satisfied with showing lower rate of satisfaction. The priority of privatization in consideration among them were following in order of food waste resource plants(76.2%), incinerators(63.6%), and recycling facilities(53.9%) and the most considerable reason to privatize them was due to resolve financial problems(59.7%). They thought and expected that the privatization would provide cost reduction effects in local governments and also be easier to achieve the environmental goals. To enhance such privatization, expanding more incentives by central government would be essential as shown in the investigation of this survey.

The purpose of this study is to find out the successful way of the hospital management focusing on the OCS. More than 40 educational hospitals have OCS. However, only five of them were chosen for the research. Questionnaires are collected from more than 750 persons working in five educational hospitals and some of them were interviewed. The major conclusions of the study can be summarized as follows: o The OCS has simplified the treatment procedure for outpatients, and the outpatients' waiting time has been shortened. o Higher rate of satisfaction was found among the personnel in general. o The number of patients who visited outpatients clinics has increased, so as the hospital profits: the personnel are rescheduled or sent to other departments the number of employees in hospitals have decreased. o The system has the positive effect on large hospitals with over 1000 beds, highly invested hospitals, well computerized hospitals and where the personnel are much interested in the system. o The managers' and the doctors' intention to utilize the OCS is the most important factor influencing the patients' convenience, the simplification of the work and the rate of the employees' satisfaction about their duties. The suggestions for more efficient hospital management through the OCS are as follows ; o The managers and the doctors are need to decide to make active use of the OCS. o The hospital can be run more effective under the clear management purpose. o The work in the hospital must be standardized based on patients' needs. o The OCS must be built and developed mainly for the users' utility. o The education of the personnel and the inspection of the program are necessary before the OCS is introduced. o The hardware should be thoroughly benchmarked before the purchase.

In this paper, we provide opportunistic scheduling schemes for elastic services in OFDMA systems with fairness constraints for each user. We adopt the network utility maximization framework in which a utility function is defined for each user to represent its level of satisfaction to the service. Since we consider elastic services whose degree of satisfaction depends on its average data rate, we define the utility function of each user as a function of its average data rate. In addition, for fair resource allocation among users, we define fairness requirements of each user by using utility functions. We first formulate an optimization problem for each fairness requirement that aim at maximizing network utility, which is defined as the sum of utilities of users. We then develop an opportunistic scheduling scheme for each fairness requirement by solving the problem using a dual approach and a stochastic sub-gradient algorithm.

Objective : We evaluated the therapeutic effect of Banwhasasimtang dry extract powder on gastrointestinal symptoms and its side effects in patients with functional dyspepsia. Methods : Patients with functional dyspepsia, defined as discomfort in the epigastrium. A total 45 patients participated in this study. Dyspeptic symptoms ratio was obtained by patients, total point of symptom score/total 21 points x 100(%). On each of symptom after 4 weeks administration of Banwhasashim-tang was made by variation of symptom score: If symptoms score of posttreatment is lower than that of pretreatment, it is improved ; Otherwise aggravated, and if there is no change between them, unchangeable. When a full health condition of normal control is assumed 100%, relative health condition of dyspeptic patient could be calculated from 'full health condition-dyspeptic symptoms ratio'. Therefore a whole satisfaction rate on symptom improvement was presented with variation of a relative health condition to dyspepsia between pretreatment and post. Results : Banwhasashimtang significantly improved symptoms in patients. The significance was shown in both all seven items(p<0.01, respectively) and 19.2% (p<0.01) of increase of a whole satisfaction rate on symptom improvement. There is no remarkable side-effect in all laboratory test, excepting 1 case of abdominal pain and another one case of recurred pain of chronic prostatitis. Conclusion : Banwhasashimtang extract provides symptomatic relief in functional dyspepsia and is no remarkable side-effect drug.

The purpose of this study is to investigate the participation of vocational training program of construction engineers and the impact of workplace learning (formal learning and informal learning) on human resource performances of construction engineers. The data of 306 construction engineers were extracted from 10,069 workers in various industries those were collected by 6th human resource company panel survey done by Korea Research Institute of Vocational Education & Training. This study found that, compared with workers in other industries, participation rate of construction engineers in workplace learning (formal learning, informal learning) was relatively low, and especially the participation rate of informal learning was significantly low. Regression analysis showed that participation in formal learning did not affect positive job performance and job satisfaction. On the other hand, informal learning has a positive effect on job capability, job satisfaction, and organizational commitment.

The elderly population is rapidly increasing worldwide, but many face challenges in using digital tools like the Internet due to health and incapacity issues. Existing online search user interfaces (UIs) often overlook the specific usability needs of the elderly. This study proposes an adaptable web search UI model for the elderly, based on their perspectives, to enhance search performance and usability. The proposed UI model is evaluated through comparative usability testing with 20 participants, comparing it to the Google search UI. Effectiveness, efficiency, and satisfaction are measured using task completion time, error rate, and subjective preferences. The results show significant differences (p > 0.05) between the proposed web search UI model and the Google search UI. The proposed UI model achieves higher subjective satisfaction levels, indicating better alignment with the needs and preferences of elderly users. It also reduces task completion time, indicating improved efficiency, and decreases the error rate, suggesting enhanced effectiveness. These findings emphasize the importance of considering the unique usability needs of the elderly when designing search UIs. The proposed adaptable web search UI model offers a promising approach to enhance the digital experiences of elderly users. This study lays the groundwork for further development and refinement of adaptable web search UI models that cater to the specific needs of elderly users, enabling designers to create more inclusive and user-friendly search interfaces for the growing elderly population.
