Objectives: The purpose of this study was to perform basic study on environmental and respiratory diseases in Ulsan and vicinities. Also, this study evaluated the actual state of environmental disease and health education at middle and high schools in Ulsan and surroundings. Methods: For this study, we conducted a survey on the health of the general public, environmental effects, and investigated the characteristics of environmental disease, health and hygiene education, etc. The populations of this study were middle and high school students in Ulsan, Korea. This study investigated the knowledge of environmental disease and health education at schools in Ulsan and vicinities from November 2009 to December 2009. All statistical calculations were performed with Statistical Package for Social Sciences (SPSS) for Windows, and gained the following results by implementing Frequency Analysis, Cross-tabulation Analysis and ANOVA. Results: As more and more environmental diseases are increased, the interest of the people has been increasing on this. The incidence rates of asthma and atopy were represented the top 25% of the country in Korea. The source of heavy metal, PAHs and VOCs in Ulsan includes the Petrochemical Complex at Nam-gu and Ulju-gun, the Nonferrous Metal Industrial Complex at Onsan-eup, Ulju-gun, and the Heavy Industrial Complex at Dong-gu and Buk-gu. Especially, there are a number of fossil fuel combustion facilities such as waste incineration plants and boilers at Nam-gu and the Onsan Industrial Complex. It may help greatly to investigate the characteristics of environmental pollutants such as environmental air pollutant and indoor contaminant to better manage the local student's health. Conclusions: It has been revealed that the hazardous chemicals and environmental contaminants are main substances of cause for asthma, atopy, dermatitis, and allergy disease. Therefore, through with collecting basic data such as environmental disease of inhabitants, health education, conscious and knowledgeable level in parents of students and students, We have to exert to improve knowledge and prevention with health life in school through development of health education program systematically for preventing of environmental disease.

The purpose of this research is to analyze the relationships between spatial characteristics and social functions of elderly center in apartment complex. The data for the analysis were collected from July 3 to 13, 2012 in Ulsan by interviewing 177 elderly persons from 56 elderly centers in apartment complex, and were analyzed with descriptive statistics, analysis of variance, and multiple regression analysis. The eleven questions for social functions of elderly center were developed by the researchers based on the related literatures and were categorized into four factors including kinship, social interaction, leisure activity, and community belonging. The social functions of elderly center were found to be evaluated moderately appropriate except for the community belonging. The results of the multiple regression analysis of total social functions of elderly center provide strong support for the model. Five variables (one-person household, health condition, location of the center, floor plan of the center, and user organization) are shown to be significantly related to total social functions of the elderly center.

Today, endoscopic procedures are common in diagnostic and other surgical procedures, with endoscopically enhanced and magnified images permitting surgical access through minimal incisions. This has expanded the treatment options for many difficult anatomic sites, and the endoscope facilitated safe anatomic reduction and fixation. The use of the endoscope may reduce the disadvantages of open fracture repair and should be considered for broad application in the treatment of displaced facial bone fractures. Optical endoscopic magnification minimizes the disadvantages associated with open surgical repair, including the risk of facial nerve injury and external facial scarring, and no postoperative complications have been attributable to the endoscopic approach. This technique was used in 14 patients treated at Ulsan University Hospital, Korea, from September 2004 to August 2006, including six mandibular subcondyle fractures, five blowout fractures and three zygomaticomaxillary complex (ZMC) fractures. Careful preoperative evaluation and proper surgical technique were essential to achieve optimal results in the selected patients.

온산공업단지는 인근에 울산석유화학단지가 위치해 있고 동쪽에는 바다가 위치하고 있는 공업지역이다. 이러한 이유로 온산공업단지에서 배출되는 대기오염물질은 특히, 해풍과 같은 기상인자에 영향을 받기 쉽다. 본 연구에서는 기상자료를 분석하여 해풍과 박무발생 빈도를 평가하였으며, 온산공업단지 인근의 기상현상에 의해 영향을 받는 대기오염물질의 농도를 평가하기 위해 상층바람조건과 온위를 분석하였다. 분석결과, 박무와 해풍이 발생될 때, 미세먼지($PM_{10}$)는 각각 57.2%, 71.8%, 이산화황($SO_2$)은 46.6%, 57.7%로 고농도 현상이 나타났다. 이런 결과를 통해 박무와 해풍과 같은 기상현상이 대기오염물질의 고농도에 영향을 주는 것을 확인하였다. 온위와 상층바람조건을 활용한 상층기상을 분석한 결과, 해풍에 의한 울산석유 화학단지에서 배출된 대기오염물질의 이류가 온산공업단지 인근의 고농도 현상에 영향을 주는 것을 확인하였다. 특히, 안정한 대기조건에서 해풍이 발생했을 때, 온산공업단지의 평균농도에 비해 1.5배 이상 고농도 현상이 나타났다.

Hypoplastic left heart complex (HLHC) consists of less severe underdevelopment of the left ventricle without intrinsic left valvular stenosis, i.e., a subset of hypoplastic left heart syndrome (HLHS). HLHC patients may be able to undergo biventricular repair, while HLHS requires single ventricle palliation (or transplant). However, there is no consensus regarding the likelihood of favorable outcomes in neonates with HLHC selected to undergo this surgical approach. This case report describes a neonate with HLHC, co-arctation of the aorta (CoA), and patent ductus arteriosus (PDA) who was initially palliated using bilateral pulmonary artery banding due to unstable ductus-dependent circulation. A postoperative echocardiogram showed newly appearing CoA and progressively narrowing PDA, which resulted in the need for biventricular repair 21 days following the palliation surgery. The patient was discharged on postoperative day 13 without complications and is doing clinically well seven months after surgery.

Objective : Little consensus exists concerning which temporal lobe structures need to be resected or how much resection should be done during hippocampal resection. The purpose of this study is to identify whether the extent of hippocampal resection influences seizure after anterior temporal lobectomy. Materials and Methods : The extent of hippocampal resection was assessed in 96 patients who underwent temporal lobectomy for medically intractable complex partial seizures originating from a unilateral seizure focus in the anteromesial temporal lobe. Patients who had structural lesion were excluded from the study. Postoperative magnetic resonance imaging in the coronal and saggital planes were used to quantify the extent of the hippocampal and lateral cortical resection. The patients were divided into two groups. Patients who underwent hippocampal resection to the level of the cerebral peduncle were included in the partial resection group, and those who had resection to the level of the colliculus were assigned to total resection group. Seizure outcomes were defined according to the Engel classification and compared between the two groups. Neuropsychologic outcomes in the selected cases were reviewed. Results : The over-all seizure-free outcome(Engel classification 1) was accomplished in 75%(72/96) of the patients (mean duration of follow-up, 36.8 months). The total hippocampectomy group had a statistically superior seizure outcome than the partial hippocampectomy group(87.3% versus 58.5% seizure-free, p-value=0.001). Also, younger patients had a more favorable outcome. Other variables such as laterality, the extent of lateral cortical resection, age at onset and gender were not significant. The pre- and postoperative memory functions were evaluated in 24 patients. A worse postoperative memory outcome was associated with partial hippocampectomy. However this was not acceptable due to a former bias. Conclusion : The result of this study conforms that aggressive hippocampectomy resulted in a better seizure outcome.

Osteoporotic fracture (OF), along with bone mineral density (BMD), is an important diagnostic parameter and a clinical predictive risk factor in the assessment of osteoporosis in the elderly population. However, a genome-wide association study (GWAS) on OF has not yet been clarified sufficiently. To identify OF-associated genetic variants and candidate genes, we conducted a GWAS in a population-based cohort (Korean Association Resource [KARE], n=1,427 [case: 288 and control: 1139]) and performed a de novo replication study in hospital-based individuals (Asan and Catholic Medical Center [ACMC], n=1,082 [case: 272 and control: 810]). In a combined meta-analysis, a newly identified genetic locus in an intergenic region at 10p11.2 (near genes FZD8 and ANKRD30A ) showed the most significant association (odd ratio [OR] = 2.00, 95% confidence interval [CI] = 1.47~2.74, p=$1.27{\times}10^{-6}$) in the same direction. We provide the first evidence for a common genetic variant influencing OF and genetic information for further investigation in bone metabolism.
