The sustainable development of local communities is faced with limitation due to poor infrastructure and lack of cooperation among stake-holders. To overcome such circumstances and thus to ensure balanced development of the local communities, the central government is driving construction of innovative cities mainly through transfer of public institutions to local cities. In this study, to contribute to the development of plans for the future agropolis' associated with the transfer of public institutions, efficient organization mechanisms of the agropolis such as basic structure and spatial allocation was examined through analyses of advanced cases(Sophia Antipolis, St. Hyacinthe Science Part Food Valley, Stoneleigh Park) of foreign countries. The analyses showed that the organization of agropolis were consisted of three main components; 1) agricultural and food industry complex conducting R&D, 2) service facilities(information, trade, consulting and advertisement) supporting agricultural and food industries and rural enterprise center in charge of a variety of events including exhibition, rural experience, education, and contest, 3) silver facilities such as hospital and town providing medical service and residence. Based on the results, inventories of facilities which are necessary in 'the future agropolis' and their spatial allocation were suggested.

In order to understand the variation of air quality and the concentration of atmospheric particulates in Chengdu Second Ring Road renovation project, this paper starts to investigate the surrounding residents' opinions on the influenced environment and their daily lives via questionnaires. Then the study numerically simulates the change rule of atmospheric particulates in terms of time and space by using the Gaussian dispersion-deposition model and the compartment model. The optimized scientific scheme is selected by the improved fuzzy analytical hierarchy process(FAHP) to help decision making for the future urban reconstructions. Finally, the reduced emissions of atmospheric particulates are measured when the improvement scheme is provided. According to the study, it can be concluded that the concentration of atmospheric particulates increases rapidly in central Chengdu city during the renovation project, which results in worsening air quality in Chengdu during March 2012 to March 2013. Taking related measures on energy saving and emission reduction can effectively reduce the concentration of atmospheric particulates and promote economic, environmental and social coordination.

The wireless sensor network (WSN) based ECG and body temperature measuring system for ubiquitous health-care were designed and developed. The system was composed of a wireless sensor network node, base station and server computer for the continuous monitoring of ECG signals and body temperatures of patients at home or hospital. ECG signal and body temperature data, important vital signals which are commonly used in clinical and trauma care, were displayed on a graphical user interface (GUI). The data transfer from sensor nodes on patients' body to server computer was accomplished through a base-station connected to a server computer using Zigbee compatible IEEE802.15.4 standard wireless communication. Real-time as well as historical, ECG data of elderly persons or patients, can also be retrieved and played back to assist the diagnosis. The ubiquitous health care system presented in this study can effectively reduce social medical expenses, which will be increased greatly in the coming aging society.

This study aims to examine curvilinearly moderating effects of task interdependence on the relationship between demographic faultlines and group performance. It posits that the degree of task interdependence has an impact on the effects of demographic faultlines. It was conducted in six organizations in Korea, their industries including heavy industries, hospital, construction, petrochemical, fine chemicals, and system integration. The survey was distributed to 1330 individuals in 162 teams and 1082 individuals in 137 teams responded to the questionnaire. To test the hypotheses including nonlinear interactions, we conducted a hierarchical regression analysis to the survey data from 82 groups within six firms in Korea. The results show that for groups that experience a high level of task interdependence, the slope for the regression of demographic faultlines on group performance is comparatively low and, at the low level of task interdependence, insignificant. However, at intermediate levels of task interdependence, the association was strongly negative and significant. This study finds that the negative relationship between demographic faultlines and group performance is stronger when task interdependence is moderate than when task interdependence is high or low. Therefore, managers should pay attention to optimal group design by carefully assigning tasks in diverse and divided groups.

The purpose of this study is to examin wearing satisfaction and needs of the caregivers' uniforms. The questionnaire survey was conducted on 303 who are serving in the geriatric hospital and general hospitals in Seoul and Gyeonggi, Chungcheong region. It was coherently found on the whole that the irrelevance to the fitness of size system influenced the discomfort, and the relation between discomfort and satisfaction revealed negative-correlation, and the higher the discomfort is and the lower satisfaction is, the higher their improvement needs are. Particularly, the higher the discomfort on the fitness of size system is and the lower its satisfaction is, the higher the improvement needs on the size system and activities are. As a result, the clothing construction and the selection of materials for the complement of the fitness and discomfort's incongruity is required. Namely, the yoke of the back area and the various detail for the activity, the materials satisfying stretch, good-touch, antibiotic functionality, and the expansion of the size system are needed.

Purpose: The purpose of this study was to develop and evaluate a coping scale for families of patients with schizophrenia (CSFPS). Methods: Item construction was derived from literature reviews and interviews with family members and psychiatric nurses. Content validity was tested by experts. Each item was scored on a four-point Likert scale. The preliminary questionnaire was administered to 188 family members of patients with schizophrenia. The data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: From the factor analysis, 32 items in five factors were derived. The factors were named active coping strategies, avoidance coping strategies, hospital treatment-oriented coping strategies, emotional coping strategies, and suppressive coping strategies for problematic behaviors. The five factors explained 49.7% of the total variance, Cronbach's alpha of the total items was .83 and the factors ranged from .66 to .86. Conclusion: The results of this study suggest that CSFPS is a reliable and valid instrument to measure coping in families of patients with schizophrenia.

In the current field of Medical Informatics, the information increases, and changes fast, so we can access the various data types which are ranged from text to image type. A small number of technician digitizes these data to establish database, but it is needed a lot of money and time. Therefore digitization by many end-users confronting data and establishment of searching database is needed to manage increasing information effectively. New data and information are taken fast to provide the quality of care, diagnosis which is the basic work in the medicine. And also It is needed the medical database for purpose of private study and novice education, which is tool to make various data become knowledge. However, current medical database is used and developed only for the purpose of hospital work management. In this study, using text input, file import and object images are digitized to establish database by people who are worked at the medicine field but can not expertise to program. Data are hierarchically constructed and then knowledge is established using a tree type database establishment method. Consequently, we can get data fast and exactly through search, apply it to study as subject-oriented classification, apply it to diagnosis as time-depended reflection of data, and apply it to education and precaution through function of publishing questions and reusability of data.

A cDNA, encoding the human growth hormone (hGH), was synthesized based on the known 191 amino acid sequence. Its codon usage was optimized for a high level expression in Escherichia coli. Unique restriction sites were incorporated throughout the gene to facilitate mutagenesis in further studies. To minimize an initiation translation problem, a 624-bp cassette that contained a ribosome binding site and a start codon were fused to the hGH-coding sequence that was flanked between the EcoRI and HindIII sites. The whole fragment was synthesized by an overlapped extension of eight long synthetic oligonucleotides. The four-short duplexes of DNA, which were first formed by annealing and filling-in with a Klenow fragment, were assembled to form a complete hGH gene. The hGH was cloned and expressed successfully using a pET17b plasmid that contained the T7 promoter. Recombinant hGH yielded as much as 20% of the total cellular proteins. However, the majority of the protein was in the form of insoluble inclusion bodies. N-terminal amino acid sequencing also showed that the hGH produced in E. coli contained formyl-methionine. This study provides a useful model for synthesis of the gene of interest and production of recombinant proteins in E. coli.

Interventricular Septal Defect is probably the most common congenital cardiac lesion. Despite rapid technical advances and increasing surgical experience the risk of surgical intervention for correction of Ventricular Septal Defect in infants with pulmonary hypertension remains formidable. Since Sirak et al [1959] reported a succesful case of two stage approach to their surgical correction, it has led to a policy of primary palliation,followed by complete correction as a secondary procedure, after age 3 to 4 years. Most surgeon prefer to perform complete correction of Ventricular Septal Defect when body weight exceeds 30 Lbs. and before development of so-called Eisenmengers complex, for the good postoperative results. Authors report 2 cases of Ventricular Septal Defect with pulmonary hupertenslon, who was underwent pulmonary artery banding as a palliative procedure in the Department of Surgery,Severance Hospital Yonsei University. Case 1:4 year old male, initially a complete correction of Ventricular Septal Defect was attempted by the help of mild hypothermia and extracorporeal circulation. During the procedure of a construction of an extracorporeal by- pass, a sudden cardiac arrest developed. After resuscitation of the heart,pulmonary artery banding was performed as a palliation. On the first postoperative day the patient developed generalized tonic convulsion, cyanosis, vomiting and eventually shock. Patient discharged home after a full recovery. Case 2.: 9 month old female, the pulmonary artery constricted with Teflon patch successfully. After the patients first postoperative day several cyanotic spells developed followed by 3 cardiac arrests. This repeated until when she expired with respiratory failure.
