Hospitals contribute to energy consumption and have a negative environmental impact. This study aims to find how meaningful energy performance, reflecting good energy management and design, can be planned for hospital buildings, a category encompassing complex buildings with different setups and large differences between them. Energy-consumption characteristics were surveyed throughout Korea to establish statistical energy models. Findings confirm that different hospital departments have hugely different energy-demand profiles. Energy efficiency and energy-saving potentials on HVAC systems are presented. The energy performance analysis can be applied to a wide range of problems in energy-system design and planning, including simulations and optimizations of community energy systems.

Many companies and departments are increasingly concerned of searching their business information in correct and faster way as they share the information through the internet. LDAP has been proposed for directory server standards which supports storing, searching and managing the business information, and it has become a global standard. Current LDAP, however, cannot solve problem; such as server overloads and data synchronization. This paper describes the history and characteristics of LDAP, and proposes an architecture for solving those problem;. Since the proposed architecture is designed based on the existing LDAP architecture, it guarantees extensibility and portability of server configuration.

The Competitive power of the country in knowledge information can be determined that how efficiently useful knowledge and information can be circulated. Korean government established the second National GIS Master Plan, and constructed National Geographic Information Clearinghouse to the goal 'whole nation's internet circulation of the geographic information and practical use'. But every departments of government are trying to circulate their geographic information individually, And this case, consumer group should approach to several dissemination network in various routing line to get the geographic information. In fact, it is difficult to present the solution for uilified single dissemination network. It is difficult to present suitable linkage plan coinciding in special environment and characteristics of all systems. Consequently, in this study, we suggested linkage element that should consider far link with National Geographic Information Clearinghouse, and presented linkage plan by linkage target type.

Objectives: Bisphosphonates (BP) are widely used in medicine for inhibiting bone resorption; however bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a major side effect of BP. To date, there have been no specific reports on the incidence of BRONJ among Koreans. This study investigated the preliminary results from a nationwide survey of BRONJ in the Departments of Oral and Maxillofacial Surgery (OMFS) at individual training hospitals. Materials and Methods: A total of 15 OMFS departments (10 from dental schools, 4 from medical schools, and 1 from a dental hospital) participated in a multi-centric survey. This study assessed every BRONJ case diagnosed between January 2010 and December 2010. The patient age and BP type were evaluated. Results: A total of 254 BRONJ cases were collected. The majority of BRONJ cases were associated with oral BP therapy, while 21.8% of the cases were associated with intravenous administration. Alendronate was the drug most frequently related to BRONJ (59.2% of cases), followed by risedronate (14.3%) and zolendronate (17.0%). The average age of BRONJ patients was $70.0{\pm}10.1$ years, with a range of 38-88 years of age. With the number of BP patients in Korea reported to be around 600,000 in 2008, the estimated incidence of BRONJ is at least 0.04% or 1 per 2,300 BP patients. Conclusion: The results suggest that the estimated incidence of BRONJ in Korea is higher than the incidence of other countries. Future prospective studies should be carried out to investigate the exact epidemiological characteristics of BRONJ in Korea.

This study was conducted to investigate the present situation and problems related to the use of nursing diagnosis in practice. The data were obtained from 332 subjects (27 director of nursing service, 302 staff nurses) who worked in university hospitals in Korea from July through August 1988 using a mailed questionnaire. Data were analyzed by frequency, X$^2$ test and t-test. The findings were as follows ; 1, Clinical use of nursing diagnosis by directors of nursing service and staff nurses. 1) The majority of the nursing departments (88.9%) conducted group education on nursing diagnosis during the last 5 years and 81.5% of them kept a record format for nursing diagnosis : 88.9% of them had had prior experience with the nursing diagnosis. 2) Most of nurses (97.0%) had received education on nursing diagnosis. 2. Factors related to the clinical use of nursing diagnosis in nursing service departments and by staff nurses. 1) The one factor related to the use of nursing diagnosis in the nursing service department was the existence of a record. 2) Factors related to the use of nursing diagnosis by the staff nurses were the organization style of the nursing service department, group education during the last 5 years, existence of a record, the attitude of the director of nursing service, and prior experience of the use of the nursing diagnosis as characteristics of nursing service department and educational experience of nursing diagnosis as a character of nurse. 3. Problems with the use of nursing diagnosis. 1) The primary problem was the lack of time and personnel (mean : 3.757) ; the second problem was the lack of knowledge and will to use nursing diagnosis in practice by the staff nurses(mean : 3.546). 2) There was no significant difference in problems expressed by the director of nursing services and the nurses. The majority of nurses who worked in the university hospitals expressed interest in and concern about the use of nursing diagnosis. Most of the nurses had had education about on nursing diagnosis but use in practice was limited. The primary problem was lack of time and manpower. Strategies for improving use of the nursing diagnosis in practice : 1) Strengthening the education about nursing diagnosis and a holistic approach to understanding human beings. 2) Develop protocols for the use of nursing diagnosis. 3) Eliminate the language barrier regarding nursing diagnosis by translation into in Korean. 4) Decentralization of the nursing service to promote accountability by individual nurses for use of nursing diagnosis.

The objective of the present studies was to develop and validate a system for isolation, purification and extended culture of pigment-producing cells in alpaca skin (melanocytes) responsible for coat color and to determine the effect of alpha melanocyte stimulating hormone treatment on mRNA expression for the melanocortin 1 receptor, a key gene involved in coat color regulation in other species. Skin punch biopsies were harvested from the dorsal region of 1-3 yr old alpacas and three different enzyme digestion methods were evaluated for effects on yield of viable cells and attachment in vitro. Greatest cell yields and attachment were obtained following dispersion with dispase II relative to trypsin and trypsin-EDTA treatment. Culture of cells in medium supplemented with basic fibroblast growth factor, bovine pituitary extract, hydrocortisone, insulin, 12-O-tetradecanolphorbol-13-acetate and cholera toxin yielded highly pure populations of melanocytes by passage 3 as confirmed by detection of tyrosinase activity and immunocytochemical localization of melanocyte markers including tyrosinase, S-100 and micropthalmia-associated transcription factor. Abundance of mRNA for tyrosinase, a key enzyme in melanocyte pigment production, was maintained through 10 passages showing preservation of melanocyte phenotypic characteristics with extended culture. To determine hormonal responsiveness of cultured melanocytes and investigate regulation of melanocortin 1 receptor expression, cultured melanocytes were treated with increasing concentrations of ${\alpha}$-melanocyte stimulating hormone. Treatment with ${\alpha}$-melanocyte stimulating hormone increased melanocortin receptor 1 mRNA in a dose dependent fashion. The results demonstrated culture of pure populations of alpaca melanocytes to 10 passages and illustrate the potential utility of such cells for studies of intrinsic and extrinsic regulation of genes controlling pigmentation and coat color in fiber-producing species.

Purpose: Ongoing treatment and care, as well as initial stabilization, are required for trauma patients. With increasing number of sickest trauma patients and shortage of surgeons, the need for advanced practice nurse to provide and coordinate trauma care has been greater. The purpose of this study is to analyze the effect of hiring a trauma clinical nurse specialist and its influence on the treatment of trauma patients. Methods: Based on the employment of the clinical nurse specialist in December 2010, the patients were divided into two groups: patients admitted from January 1, 2010 to November 30, 2010 and patients admitted from December 1, 2010 to December 31, 2011. Retrospectively, data were collected using electronic medical records. The general characteristics, clinical courses, and ICU re-admission rates, collaboration (transfers to other departments and collaborative surgery) were compared. Results: To have a clinical nurse specialist on the trauma team resulted in a statistically significant reductions in the length of general ward hospital stay (p<0.05), the ICU re-admission rate, (p<0.03), the lead-time before transfer to other departments (p<0.05). Conclusion: The clinical nurse specialist, as a professional practitioner, improved the quality of treatment through early detection and management of problems. In addition, as a coordinator, the clinical nurse specialist maintained a cooperative relationship with multi-disciplinary medical personnel. The trauma clinical nurse specialist contributed to the treatment of trauma patients positively through a decrease in ICU re-admission rate and length of hospital stay.

Purpose: This study was to investigate oral hygiene knowledge and the actual condition of oral care for the students in the public health and non-public health Departments. Methods: The survey sample consisted of 262 randomly selected students. 197 of them are public health-related students and 65 are non-public health-related students. The questionnaires used in this study consisted of 4 items for general information, oral health status of 2 items, 5 items for Oral hygiene knowledge and actual condition of oral care of 5 items. Collected data were analyzed by Frequency Analysis t-test and Crosstabs using SPSS(Statistical Package for Social Sciences) Win 19.0 statistics program. Results: Regarding general characteristics of the subjects, there were 53.8% of first-year student, 26.0% of second-year student and 20.2% of third-year student among 52.3% of males and 47.7% of females. The subjects received less than "100,000" won(13.0%), "100,000-190,000" won (5.0%), "200,000-290,000" won(30.9%), "300,000-390,000" won (33.2%) and more than "400,000" won(17.9%) a month for an allowance. The subjects had 'none' (44.3%), '1'(6.5%), '2'(12.6%), '3'(5.0%), '4'(5.3%), 'more than' 5(0.8%) of dental caries and 'do not know' were 25.6%. The numbers of dental prosthetics were 'no' (35.5%), '1'(13.7%), '2'(17.2%), '3'(10.3%), '4'(11.5%), and 'more than 5'(11.8%). The public health students(84.8%) had a higher positive response rate than the non-public health students(66.2%). The public health students(80.2%) had a higher negative response rate than the non-public health students(78.5%) in the result of onset of gum disease pain awareness. The non-public health students(65.5%) had a higher negative response rate than the public health students(68.3%)) in the result of heredity of gum disease. The t-test showed that public health-related department students(M=8.264, SD=0.821) had more knowledge about oral hygiene than non-public health-related department students(M=8.015, SD=1.082). 'do not use' in the oral care products except toothpaste and toothbrush showed that public health-related department students(60.4%) use the products more than non-public health-related department students(66.2%). Conclusion: In this study, public health-related department students had higher oral hygiene knowledge and actual condition of oral care compared to non-public health-related students, but low in practical action. Due to the lower level of dental care products use in non-public health-related department, a continuous oral care education program is required.

We reviewed retrospectively the medical records of 600 elderly patients, over 65 years old who visited oral medicine. The ratio of the age group was composed of 65${\sim}$74 years old group was 63.7%, 75${\sim}$84 years old group was 32.2%, over 85years old group was 4.2%, and the patients were mostly females. The main chief complaint was composed of oral soft tissue problem(44.1%) and oromaxillofacial pain(39.0%). The majority of systemic diseases was composed of diseases of the circulatory system(30.1%), diseases of the musculoskeletal system and connective tissue(16.8%), endocrine, nutritional and metabolic diseases, and diseases of the digestive system(10.1%). The numerous pateints were diagnosed as soft tissue disease(32.0%), arthrogenous disease(24.1%), and myogenous disease(18.1%) of temporomandibular disease.Principally medication(43.9%), physical therapy(24.2%) were performed. 14.2% of all patients visited oral medicine with a letter of request written by other medical departments or local dental clinics, or referred from other departments in Chosun university dental hospital. These findings indicate epidemiologic characteristics on the elderly patients visited oral medicine. We hope that this study will play a basis in the future research about the elderly patients.

The Ministry of Education of Korea announced the university structural reform plans which reduces 160,000 of the university entrance quota during 10 years from January 2014. Because the reduction plans of entrance quota influence regional economy as well as students and universities, naive evidence of the Ministry of Education of Korea is disappointed. In this research, we forecast the total number of the university entrance exam candidate by 2032 including not only third grade high school students but also repeaters according to the 16 metropolises and provinces in Korea. We also forecast the regional university recruiting rate using the forecasts of the total number of the university entrance exam candidates. However, we can not make more realistic results because we can not apply the inter-regional movement of students to the forecast. In order to handle this limitation, we first estimated the rank of the whole 7,277 departments of all universities in Korea and assigned the quotas according to the estimated rank for each departments and then we calculated the local university recruiting rate. The estimated the university recruiting rates of 16 metropolises and provinces can provide more noticeable results of characteristics and problems than that of nationwide.
