This study analyzes the changes of Gyeongju local society because of setting up low and intermediate level radioactive waste disposal site by using urban dynamics model. Specifically, after examining 'Gyeongju Long-Term Development Plan' announced in 2007, I establish the number of industries, population, gross local product, residents' income, and the long term employment condition as essential change-causing factors in Gyeongju local society based on the Big3 government project, and forecast it by using 'Gyeongju long-Term Development Plan' and all sorts of statistical data. In this stage, I assume 3 scenarios(basic, optimistic, and pessimistic view) to estimate the changes of local society more exquisitely, and scenarios are composed through mediation about variables of a growth rate and an inflow or outflow rate. The result shows that Gyeonaju local society would have growing changes by 2020. The essential change-causing factors are as follows. The case of population is estimated that it starts going down at the level of approximately 270 thousand by 2009, starts going up continuously after 2009, the year of completion of low and intermediate level radioactive waste disposal site, and increases from the level of about 300 thousand as minimum to 340 thousand as maximum in 2020. The estimates of other cases are made that the number of Industries has about 10 thousand increases, gross local product has almost 6 trillion increases, nominal gross national income doubles, as well as residences have approximately 280 thousand increases, and also made that employment condition also improves continuously, and diffusion ratio of house starts going up but the amount of supplies is a little bit insufficient in the long view.
Preface: Dental implant is important method that may solve the mastication, occlusion, esthetic, temporomandibular joint, and psychologic problem in oral and maxillofacial surgery. It is ideal that all of the implant are well positioned by adequate technique. By the way it‘s not always possible because of some anatomic, physiologic factor. In this case, If the implant can be moved to adequate position, it may be possible more esthetically and implanted patients more satisfied, but the majority of Implantists and orthodontists have thought that it is not possible. However, Implant, in fact, can be moved. and thus we can overcome the limit of implantation more. The aim of the present study was to evaluate the possibility of implant movement after corticotomy. Case report: Patient missed the upper right first molar. and implantation was done after completion of socket healing. We wait six months for osseointegration. Then, corticotomy was done under local anesthesia and close coil was used for orthodontic force. After traction during 3 weeks, we find the change of implant position at horizontal plane. we can not see the degenerative change on adjacent structure and tracted implant. there is a clinical mobility on upper right second premolar that used for anchorage but it subside spontaneously at the timing of prosthetic restoration without additional treatment. Discussion: As we could have some knowledge with this experiment, we report the case of implant movement after corticotomy and suggest a method about more esthetic implant treatment with a review of literature.

Labor work information can be converted into the useful construction information in an effort to analyze project status, measure performance, and design a new similar project plan. The labor work information can also be used to make productivity data, which can be used to analyze the relationship between 'as planned' and 'as built' in scheduling management of a project, and to calculate 'percent completion' as well as analyzing delay cause. It is require to effectively collect the labor work information base on the activities. In general, current project management heavily depends on the experience and judgment of project managers, according to the work progress. However, relying on the oかy experience and judgment of the project managers might deteriorate the transparency or reliability of the collected labor work information. The purpose of this research is thus to develop a computer-based system for monitoring the work information generated by labors input in activities using PDA and Barcode technologies, and to propose a application method of the productivity data for effective project management.
Background and Objectives : Although it is well established that patients with papillary thyroid microcarcinoma (PTMC) have a highly favorable prognosis, the extent of thyroid surgery for PTMC remains unclear. According to the 2011 revised Korean Thyroid Association guideline, the choice of surgical strategy(total thyroidectomy versus lobectomy) for PTMC depends on solely preoperative diagnostic scrutinies-ultrasonography and fine needle aspiration cytology. We want to know how accurately these preoperative diagnostic scrutinies define the choice of surgical strategy for PTMC. Materials and Methods : For 119 patients who underwent total thyroidectomy with central neck dissection for PTMC, retrospectively, we compared the choice of surgery according to preoperative work up and postoperative pathologic findings. Results : Overall accuracy of the choice of surgery by preoperative work up was 61%. Among patients recommended lobectomy on preoperative work up, completion thyroidectomy on postoperative pathology might be necessary for 60% of patients and hidden central node metastasis was revealed in 31% of patients. Conclusions : The results of this study compel us to reinvestigate the current treatment guideline for PTMC. On current guideline according to the sonography and fine needle aspiration cytology, it might be thought to be better to choose more aggressive surgical strategy.
Purpose: This investigation aimed to determine the effects of treadmill training (TT) and high frequency chest wall oscillation (HFCWO) on pulmonary function and walking ability in stroke patients as well as propose an exercise program to improve cardiovascular function. Methods: Twenty hemiplegic stroke patients were randomized to either the control group (CG) (n=10) or the experimental group (EG), which received TT and HFCWO (n=10). Pulmonary function was quantitated using patient forced vital capacity (FVC) and forced expiratory volume at one second (FEV1) while walking speed was assessed by the 10m walking test (10MWT). Further, walking endurance was determined utilizing the 6-minute walk test (6MWT). Subjects of the EG performed the study protocol for 60 minutes, five times a week for six weeks; CG patients did not participate in regular exercise. To determine significance for the differences observed before and after exercise, within-group and between-group comparisons were conducted utilizing paired and independent t-tests, respectively, with the level of significance set at ${\alpha}=0.05$. Results: Within-groups, significant differences were observed in both FVC and FEV1 (p<0.01) following completion of the study protocol. Further, between-group comparisons demonstrated significant differences in both FVC (p<0.05) and FEV1 (p<0.01). Post-exercise, significant changes in the 10MWT and 6MWT score were observed between the EG and CG (p<0.01). Further, statistically significant differences were observed in 6MWT scores between-groups (p<0.05). Conclusion: The TT and HFCWO effectively improved pulmonary function and walking ability in subjects with stroke. The proposed program can be applied to stroke patients as a useful therapy.

BangPungTongSung-San is usually perscribed in Hyungsang medicine for those of Yangmyung type, Pung type, those who have inner fever as well as redness of the tip of the nose, and for those with the external shape who tend to have dandruff. Following conclusions were obtained from the treatment of 8 patients suffering from inflammatory dermatitis. The causes of inflammatory dermatitis are mainly wind-fever, poisonous fever of the Samcho, dry-fever, and congenital conditions. The inflammatory dermatitis usually occurre to people who belong to Yangmyung types having vigorous Yangmyung meridian and body heat. Some patients who did not belong to the Yangmyung type were either those with much body heat or having congenital conditions inherited from their parents. There was no difference in the frequency of disease between men and women. The disease occurred at the times bodily conditions were weak or significant physiological changes took place. The term for the treatment required at least 3 months. Three more months are considered to be needed in treatment even after the completion of the remedy observing the return of the disease. The inflammatory dermatitis is easily occurred and recurred to those who belong to Yangmyung type and therefore the best prevention would be appropriate diet and bodily manner in daily life.

The fetal central nervous system (CNS) is sensitive to diverse environmental factors, such as alcohol, heavy metals, irradiation, mycotoxins, neurotransmitters, and DNA damage, because a large number of processes occur during an extended period of development. Fetal neural damage is an important issue affecting the completion of normal CNS development. As many concepts about the brain development have been recently revealed, it is necessary to compare the mechanism of developmental abnormalities induced by extrinsic factors with the normal brain development. To clarify the mechanism of fetal CNS damage, we used one experimental model in which 5-azacytidine (5AZC), a DNA damaging and demethylating agent, was injected to the dams of rodents to damage the fetal brain. 5AzC induced cell death (apoptosis)and cell cycle arrest in the fetal brain, and it lead to microencephaly in the neonatal brain. We investigated the mechanism of apoptosis and cell cycle arrest in the neural progenitor cells in detail, and demonstrated that various cell cycle regulators were changed in response to DNA damage. p53, the guardian of genome, played a main role in these processes. Further, using DNA microarray analysis, tile signal cascades of cell cycle regulation were clearly shown. Our results indicate that neural progenitor cells have the potential to repair the DNA damages via cell cyclearrest and to exclude highly affected cells through the apoptotic process. If the stimulus and subsequent DNA damage are high, brain development proceeds abnormally and results in malformation in the neonatal brain. Although the mechanisms of fetal brain injury and features of brain malformation afterbirth have been well studied, the process between those stages is largely unknown. We hypothesized that the fetal CNS has the ability to repair itself post-injuring, and investigated the repair process after 5AZC-induced damage. Wefound that the damages were repaired by 60 h after the treatment and developmental processes continued. During the repair process, amoeboid microglial cells infiltrated in the brain tissue, some of which ingested apoptotic cells. The expressions of genes categorized to glial cells, inflammation, extracellular matrix, glycolysis, and neurogenesis were upregulated in the DNA microarray analysis. We show here that the developing brain has a capacity to repair the damage induced by the extrinsic stresses, including changing the expression of numerous genes and the induction of microglia to aid the repair process.
Cooked spaghetti soaked in 10%, 20%, and 40% aqueous glycerine solutions for ten minutes absorbed sufficient glycerine to plasticize that spaghetti during and after subsequent drying. The plasticizing action of the glycerine prevented fissuring(checking) and surface corrugation of the spaghetti at elevated drying temperature and large wet-bulb dry-bulb temperature difference. The drying temperature and the wet-bulb dry-bulb differences up to which such protection was provided as the glycerine soak concentration increased. Despite the reduction in drying rate, the drying time required to produce spaghetti with a water activity of 0.65 (the level normally required for stability) decreased as glycerine content increased. At high frying temperatures glycerine addition increased the extent of browning and shortened the period required to induce detectale browning, but in all instances browning started well after the product $a_w$ reached the 0.65 value required for the completion of drying. Because glycerine addition reduced drying times at any given set of drying conditions and permitted the use of higher drying temperatures, relatively low levels of glycerine addition (e.g. 0.15 kg glycerine/kg dry spagetti) can shorten spagnetti drying times by roughly 80% and perhaps by as much as 93%.
The purpose of this study is to present the basic material for the competitive, high-quality products by analyzing employees' attitude toward their job and some factors which influence the enhancement of productivity, education of workers, and facilities. This project was mainly conducted the conditions of women's wear manufacturing industries in Taegu by interviewing 143 employees in the sewing department. The result of this dissertation can be summarized as follows; 1. When it comes to the division of task in the sewing department, one team is composed of chairpersons (33.5%), assistant members (27.4%) and sub-assistant members (26.6%). The inspection of commodities as well as the enhancement of work on ironing for elaboration was divided as completion (12.6%) and finally the forms of task were made up of design sampling team (49%) and contracting team (51%). 2. Among the needle workers, as many as 60% employees had received technical education, which was by means of being passed down from the predecessors (81.6%). In terms of the period of education, from 2 to 5 years topped the list. The contents of education comprise patterning, sewing (65.2%) and ironing (20.3%). 3. The department of design takes charge of the report on working directions up to 88.2% and the working directions were used by 69.9 % of technicians. The directors of working conditions and methods were chiefs of designing department (37.7%) and those of sewing department (30.8%). The factors of defective goods were low-quality materials (50.0%), the deficiency in skills of workers. In terms of methods for preventing defects, technical education of workers, standardization of task and investment for factory automation were suggested. 4. As for their perception of present work, most of employees (80%) look upon it as a way of earning a living and 11% of them wanted to derive many things from their work. 59.2% of workers were satisfied with the product. When it comes to the incentive system provided by company, 67.0% responsed that it was not bad, and 23.9% evaluated it as 'satisfactory'.

Purpose: This aim of the present study was to assess a newly developed education program for HIV/AIDS counseling nurses. Methods: An education program was developed based on literature reviews, previous project analysis, focus group interview and expert meetings. The program comprised of 3 levels: basic, advanced, and intensive, which included 80, 70, and 60 hours of education, respectively. From May to December in 2012, 17 counseling nurses completed the program and we evaluated their learning achievements, attitudes towards AIDS, confidence in consultation, empathic ability, and training sessions. We also measured the nurses' satisfaction with the program before and after completion. Results: After completing a monthly education program lasting 12-15 hours, the nurses' mean learning achievement was 88.5%, 88.3% and 91.4% out of the basic, advanced, and intensive levels, respectively. Although the nurses' attitudes towards AIDS did not change, their confidence and empathic abilities increased following the basic and intensive components of the programs. Satisfaction with the educational sessions and program operation was 4.23 out of 5.0. Conclusion: This newly developed education program for HIV/AIDS counseling nurses promoted learning achievements as well as, confidence and empathic ability in consultation. HIV/AIDS counseling nurses should receive continuous education opportunities to enhance their potential.
