Background/Aims: Capsule endoscopy is a diagnostic method for evaluating the small bowel lumen and can detect undiagnosed lesions. The aim of this study was to evaluate the diagnostic yield and clinical impact of capsule endoscopy in patients with refractory diarrhea-predominant irritable bowel syndrome and functional abdominal pain. Methods: This study involved a retrospective analysis of prospectively collected data, maintained in a database. Patients with refractory diarrhea-predominant irritable bowel syndrome and functional abdominal pain within the period of March 2012 to March 2014 were included. Capsule endoscopy was used to detect small bowel pathologies in both groups. Results: Sixty-five patients (53.8% female) fulfilled the inclusion criteria and had a mean (${\pm}$standard deviation) age of $50.9{\pm}15.9$ years. Clinically significant lesions were detected via capsule endoscopy in 32.5% of the patients in the abdominal pain group and 54.5% of the patients in the diarrhea group. Overall, 48% of patients had small bowel pathologies detected during the capsule endoscopy study. Inflammatory lesions and villous atrophy were the most frequent lesions identified in 16.9% and 15.3% of patients in the abdominal pain and the diarrhea groups, respectively. Conclusions: Routine use of capsule endoscopy in patients with irritable bowel syndrome should not be recommended. However, in patients with refractory conditions, capsule endoscopy may identify abnormalities.

In the event of an earthquake, non-structural components require seismic performance to ensure evacuation routes and to protect lives from falling non-structural components. Accordingly, the seismic design code proposes horizontal force for the design and evaluation of non-structural components. Ground motion observed on each floor is affected by a building's eigen vibration mode. Therefore, the earthquake damage of non-structural components is determined by the characteristics of the non-structural component system and the vibration characteristics of the building. Floor response spectra in the seismic design code are estimated through time history analysis using seismic waves. However, it is difficult to use floor response spectra as a design criterion because of user-specific uncertainties of time history analysis. In addition, considering the response characteristics of high-rise buildings to long-period ground motions, the safety factor of the proposed horizontal force may be low. Therefore, this study carried out the horizontal force review proposed in the seismic design code through dynamic analysis and evaluated the floor response of seismic waves considering buildings and predominant periods of seismic waves.

CHO 세포를 재료로 ENU와 MNU를 여러농도로 처리한후 시간 경과에 따른 염색체 이상율을 조사하여 다음과 같은 결과를 얻었다. (1) ENU와 MNU에 의한 염색체 이상 빈도는 처리 후 시간의 경과와 농도에 따라 상이한 현상을 나타냈다. (2) ENU 처리군에서는 염색체 이상형은 염색분체 절단이 대부분이었으나 고농도군 ($10^-3 M$)에서는 처리 후 24시간에 염색분체 교환이 염색분체 절단을 능가하였다. (3) MNU 처리군에서는 염색체 이상형은 염색분체 절단이 대부분이었으나 $10^-4$ M 이상에서는 처리후 12시간부터 염색분체 교환이 염색분체 절단을 능가하였다.

To study the nutritional value of warty sea squirt, Styela clava, which is one kind of urochoda and it has been used as special seafood stuffs by Korean, the seasonal variations of nutrient was investigated. The moisture content was ranged from 83.6% to 86.8% in experimental period. Maximun glycogen content showed up in June (3.7g/100g sample). The protein(N$\times$6.25) and lipid content varied with glycogen whereas ash content was not changed remarkably, showing 2.8$\pm$0.3%. Predominant minerals in edible portion and integuments were sodium, potassium, calcium and magnesium in order. Predominant constitutiional amino acids were asparagine, glutamic acid, taurine, aspartic acid, lysine and glycine and amino acids occupied 50% of the total amino acid. Porportion of nonpolar lipid to total lipid increased from April to early June while polar lipid level decreased. The neutral lipid was composed of triglyceride(59.32%) and free sterol(23.52%), and followed by diglycerides, monoglycerides, esterified sterols and hydrocarbon, free fatty acid. The phospholipid was mainly composed with phosphatidyl choline(49.7%), and phosphatidyl ethanolamine(33.0%). The major fatty acids of the total lipid in warty sea squirt were C20 : 5(17%), C22 : 6(13.76%), C16 : o(13.91%) and C16 : 1(12.52%).

Background: Carcinoma of the esophagus is associated with significant morbidity and mortality. The most common subtype is squamous cell carcinoma (SCC). In the past three decades, the incidence of SCC has been reported to be decreasing whereas esophageal adenocarcinoma (AC) is increasing. This study assessed the trend of esophageal cancer in Brunei Darussalam over a three decades period. Materials and Methods: The National Cancer registry was searched for esophageal cancers from 1986 to 2012. Data on age, gender, racial groups (Malays, Chinese, Indigenous and foreign nationals) and histology type were collected. The rate (ASR) and Age Specific Incidence rate (ASIR) were calculated. Results: The predominant tumor type was SCC which accounted for 89% of all esophageal cancer. The gender ratio was 2.25: 1 (male: female) and the mean age at diagnosis was $66.9{\pm}12.9$ years, significantly younger for esophageal AC ($57.2{\pm}16.0$) compared to SCC ($68.1{\pm}12.0$, p<0.05), and among the foreign nationals (p<0.05 for trend). The proportions of SCC among all esophageal cancers in the various racial groups were: Malays (87.8%), Chinese (100%), Indigenous (100%) and foreign nationals (20%). None of the Chinese and Indigenous groups were diagnosed with esophageal AC. The overall ASR for esophageal cancer was 2.1/100,000; 2.0/100,000 for SCC with a declining trend and 0.17/100,000 for esophageal AC, without any trend observed. Among the two major racial groups; the Chinese has higher ASR (3.42/100,000) compared to the Malays (ASR 0.95/100,000). Conclusions: SCC is the predominant tumor type of esophageal cancer in Brunei Darussalam and more common among the Chinese. There was a declining trend in the incidence of SCC but not for esophageal AC.

This is a retrospective study on 452 patients with maxillofacial bone fracture. The patients were treated at the Dept. of Oral and Maxillofacial Surgery, WON KWANG UNIV. HOSPITAL from Aug. 1, 1984 to Sept. 30, 1988. The results were as follows. 1. The facial bone fractures occured most frequently in the twenties (35.3%)and male were predominant(75%) than female. 2. The most frequent etiologic factor was traffic accident. 3. The most common location of facial bone fracture was mandible(57%). Zygomatic bone & arch(39.9%) were most common on middle 1/3 of the face and symphysis(37.1%) were most common on the mandible. 4. The time from injury to treatment was variable from under the 1 week (65%) to over the 1 week(35%). In most case of the patients were treated beyond the 3 days(51.5%). 5. The relationship of intermaxillary fixation period and treatment method was an intimate relationship. The IMF period was reduced by the use of plate and screw osteosynthesis. 6. The weight loss was proportioned to intermaxillary fixation period.
