Objective: An outbreak of skin rash illness was reported from people who had been to a water park located in Yeongcheon-si. Epidemiologic investigation was performed to elucidate the cause of this outbreak and to prevent a recurrence. Methods: Medical records of clinics and hospitals in Yeongcheon-si were reviewed to find cases of skin rash illness. The manager of the water park was interviewed, and the collected water samples were analyzed and tested for bacterial culture. Results: Seventy-one cases, consisted of 42 men (59.2%) and 29 women (40.8%), were experienced skin rash illness. Most of the cases (98.6%) were children under 20 years and all cases went to the water park. A swimming pool for adults used underground and lake water, and residual chlorine was not detected. The water samples were positive for various bacteria, including Aeromonas sobria and Pseudomonas putida. Conclusion: This outbreak was linked to the contaminated water of swimming pools. The water park was reopened after appropriate chlorine disinfection, and another outbreak was not reported until late 2014. Chlorine disinfection of water in swimming pools should be conducted, and enhanced chlorine monitoring is needed.

목적 : 농산물 소독과정에서 브롬화메틸에 노출된 근로자에게 발생한 신경병 2례 보고. 방법 : 피로감, 전신무력감, 어지럼증, 보행장애 등의 증상을 주소로 내원한 브롬화메틸을 사용하여 방역작업에 종사하는 건강한 20세와 18세의 근로자를 대상으로 혈액검사, 신경정도 및 근전도검사, 뇌자기공명영상 등의 임상검사와 작업력조사를 시행하였다. 결과 : 1례에서 뇌자기공명영상에서 연수와 소뇌의 양측 측충부의 고신호강도가 관찰되었고 11일 후의 추적조사에서 동일 부위의 고신호강토가 감소된 소견이 관찰되었으며 뇌병증으로 최종 진단되었다. 다른 1례는 신경전도검사에서 다발성 신경병 소견과 뇌유발전위검사에서 우측 하부 뇌간부위 병소가 관찰되었고 뇌병증 및 말초신경 병으로 최종 진단되었다. 결론 : 근로자들의 증상은 소독과정에서 브롬화메틸 노출로 인한 신경 병으로 판단되며 훈증소독과방역작업에 종사하는 근로자들의 실태조사와 안전에 대한 대책이 시급하다고 하겠다. Objectives : To report two cases of neuropathy due to methyl bromide intoxication. Methods : Workers, engaged in the fumigating process, complained fatigue, general weakness, ataxia, and hypersomnia. We evaluated them with blood tests, neurophysiologic studies and MRI and investigated their occupational history. Results : Increased signal intensities were found in the medulla oblongata and paraver mian of cerebellum in MRI and after 11 days, high signal intensities were reduced in the following MRI. In the other case, polyneuropathy and rlght lower brainstem lesion were observed In the NCV and BAEP studies. Conclusions : We confirmed that worker's symptoms were related to methyl bromide exposure in the fumigation. It is necessary that we should evaluate present condition of fumigating process and prepare appropriate methods to protect workers engaged in the fumigation.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

Generally, the analysis of a sodium-water reaction (SWR) is classified by two major events. One is the very initial stage of peak pressure and shock wave propagation caused by the reaction itself, and the other is the bulk motion including the mass transfer phase in the quasi-steady state of the reaction period during several second or minute orders after leak initiation. The system dynamic response during a sodium-water reaction event shows very different characteristics between the initial stage and the long-term period. In order to investigate the later phase of a SWR event. the code SELPSTA (Sodium-water reaction Event Later Phase System Transient Analyzer) has been developed and the desing and construction of the test facility has been made.

Hydrogenated amorphous carbon(a-C:H) films were prepared by PECVD(Plasma enhanced-chemical vapor deposition) method. The films were characterized using various spectroscopic measurements such as Raman scattering, FTIR(Fourier transform infrared) absorption spectroscopy. FRIR absorption reflects only the optically active hydrogen in the a-C:H and, using it together with Raman spectroscopy. The spectral analysis indicated that changes in Raman spectroscopy intensity occurring with increasing substrate temperature 50℃~300℃ were determined to be caused by changes in optically resonant components in the films. Furthermore, a significant correlation was the two crystalline forms of carbon-graphite and -diamond consist of sp² and sp³ bonds, respectively. Significant changes in chemical bonding(sp²/sp³) and micro-structure of hydrogenated amorphous carbon thin films occur as the substrate temperature varies from 50 to 300℃ during.

In order to investigate the later phase of a sodium-water reaction (SWR) event in KALIMER (Korea Advanced Liquid MEtal Reactor), the code SELPSTA (Sodium-water reaction Event Later Phase System Transient Analyzer) has been developed and an experimeantal study has been carried out for verification of the simple analysis model applied to the code. The 24 data set obtained in the experiment have been pre-analyzed. Comparison of SELPSTA results with experimental data shows fairly good agreement in the transient.

본 연구의 목적은 유치열기 부정교합의 진단자료로 사용할 수 있는 정상 계측치를 알아보는 것이다. 4세에서 6세 사이 유치열기 정상교합아동 32명의 측모두부방사선 계측사진 및 안모사진을 이용하여 악골 및 연조직의 전후방적, 수직적 관계를 분석하였다. 수평적인 골격성 계측항목 중 SNA는 83°,SNB는 78.72°,ANB는 5.28°를 나타내어 하악골이 상악골에 비해 후방에 위치하고 있었으며 수직적인 골격성 계측항목 중 Gonial angle은 127°를 나타내어 성인에 비하여 High angle pattern을 보였다. 연조직 분석에서는 성인에 비해 convex한 soft tissue profile이 관찰되었다. 치성 계측항목 중 U1 to SN은 91.04°, IMPA는 86.57°를 나타내어 성인에 비해 reteroclination된 상하악 유중절치가 관찰되었다. 정상교합아동의 골격성분석에서 여자가 남자에 비하여 평균 나이가 많음에도 불구하고 linear measurement는 전제적으로 남자가 여자보다 큰 수치를 보였다. The present study was designed to formulate cephalometric norms of normal occlusion for usage in orthodontic diagnosis of malocclusion in Korean children. Thirty two children, aged 4 to 6. with normal occlusion were chosen for this study. Sagittal and vertical relations were analyzed using lateral cephapogram and clinical photos and the measurements were compared with those of adults. On skeletal sagittal analysis, the mean values of the SNA and SNB angles were 83°and 78.72°. It showed that the mandible was retrognathic and retropositioned in comparison to those angle pattern in children and reduction of gonial angle due to counterclockwise rotation of the mandible. On dental analysis. the mean values of the U1 to SN and IMPA were 91.04° and 86.57°, This showed retroclined upper and lower deciduous teeth in comparison to adults. For values. the linear values were generally greater in males than females.

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.
