Narrow-band imaging (NBI) is the most widely used image-enhanced endoscopic technique. The superficial microanatomy of gastric mucosa can be visualized when used with a magnifying endoscopy with narrow-band imaging (ME-NBI). The diagnostic criteria for early gastric cancer (EGC), using the classification system for microvascular and microsurface pattern of ME-NBI, have been developed, and their usefulness has been proven in the differential diagnosis of small depressed cancer from focal gastritis and in lateral extent delineation of EGC. Some studies reported on the prediction of histologic differentiation and invasion depth of gastric cancer using ME-NBI; however, its application is limited in clinical practice, and further well-designed studies are necessary. Clinicians should understand the ME-NBI classification system and acquire appropriate diagnostic skills through various experiences and training to improve the quality of endoscopy for EGC diagnosis.

The incidence of gastric neuroendocrine tumors (NET) has been increased with the improvement of endoscopy accessibility. The World Health Organization classified NET of low (G1), intermediate (G2), high (G3) grade and neuroendocrine carcinoma with poor differentiation by mitotic count and Ki-67 labeling index. Gastric NET are divided into three subtypes based on the pathophysiology, and treatment is determined according to the subtype and prognostic factors of tumor. For diagnosis, endoscopy with biopsy, endoscopic ultrasonography, abdominal pelvis computed tomography, and serum gastrin level measure are required. In general, type 3, size > 2 cm, deep submucosal infiltration, high histological grade, lymphovascular invasion and metastasis are poor prognostic factors. Type 1 or 2 without these factors are treated by endoscopic resection, and other tumors needs surgery. Endoscopic resection of early type 3 or type 1 and 2 tumors with poor prognostic factors still remains a challenge.

The Chicago Classification is being revised continuously for the accurate diagnosis of esophageal peristaltic disorders in which the etiology is unclear, and the disease behavior is heterogeneous. The ver. 4.0 was recently updated. A representative change in the diagnosis of esophageal peristaltic disorders of the ver. 4.0 showed that the distinction between major and minor disorders was eliminated and was divided into the following four diagnoses: absent contractility, distal esophageal spasm (DES), hypercontractile esophagus (HE), and ineffective esophageal motility. Compared to the ver. 3.0, it recommended a more detailed protocol of high-resolution esophageal manometry and methods of interpreting manometric. In addition, it emphasized the clinically relevant symptoms in diagnosing DES and HE, and presented provocative tests (e.g., multiple rapid swallow and rapid drinking challenge), as well as additional testing, including impedance, timed barium esophagogram and functional lumen imaging probe, which may provide more standardized and rigorous criteria for peristaltic patterns and to minimize the ambiguity in diagnosis. Although it will take time and effort to apply this revised Chicago Classification in clinical practice, it may help diagnose and manage patients with esophageal peristalsis disorder in the future.

Background: While the incidence of skin diseases in our university hospital may not indicate their true incidence in the population, it nonetheless represents the only available source of information. Recently, the composition of the Wonju population has changed rapidly in that the population of old people is increasing and urbanization is accelerating. Thus, statistical study of the latest data is necessary. Objective: To study the prevalence of common dermatoses and compare this with previous reports. Methods: We reviewed 27,718 new outpatients who visited the department of dermatology at Wonju Christian Hospital from 2005 to 2009, and statistically analyzed the findings. Results: The study results are summarized as follows: Of the 27,718 outpatients, the total number of male patients was 14,190 (51.2%), and the numbers of female patients was 13,528 (48.8%). The most frequent age groups were the fifth decade (15.9%), sixth decade (13.9%), seventh decade (13.2%), and fourth decade (12.5). The 20 most common dermatoses were dermatophytosis, urticaria, atopic dermatitis, allergic contact dermatitis, other eczema, verruca, alopecia, herpes zoster, pruritus, psoriasis, drug eruption, vitiligo, acne, seborrheic dermatitis, folliculitis, benign epidermal tumors, nevocellular nevus, irritant contact dermatitis, bacterial diseases, and rosacea. The dermatoses which revealed a decreasing tendency to be treated by medicine included dermatophytosis, atopic dermatitis, other eczema, pruritus, psoriasis, drug eruption, vitiligo, acne, and irritant contact dermatitis. An increasing tendency was noted in urticaria, allergic contact dermatitis, verruca, alopecia, herpes zoster, seborrheic dermatitis, folliculitis, benign epidermal tumor and nevocellular nevus. Diseases with high seasonal distribution in summer were dermatophytosis, herpes zoster, vitiligo, folliculitis, irritant contact dermatitis and bacterial infections. However, atopic dermatitis, pruritus, and psoriasis showed high incidence in the winter period. Verruca, acne and nevocellular nevus had a peak incidence in both summer and winter. Conclusion: The distinct characteristic of skin diseases of the Gangwon province was a high incidence of pruritus and seborrheic dermatitis which represent the senile diseases.

N/A Background: Medications for asthma can be administered either by inhaled or systemic routes. The major advantages of delivering drugs directly into the lungs via inhalation are that higher concentrations can be delivered more effectively to the airways and that systemic side effects are avoided or minimized. Inhaled medications, or aerosols, are available in a variety of devices that differ in required technique and quantity of drugs delivered to the lung. Objective : The purpose of this study was to determine the effects of patient education on correct use of metered dose inhaler in patients with asthma. Methods : Twenty patients with asthma were instructed three times on proper inhaler usage by a physician at two-week intervals. Practical performance and theoretical knowledge were assessed (ten-item assessment). Scoring was done by one physician using a score of 1-3 for each item. Results : The practical performance and theoretical knowledge scores were higher in patients after being instructed three times compared with those who were instructed once (26.2±2.2 vs 18.1±3.6, p< O.01). The scores were higher in patients with higher education level compared with those with lower education level after three lessons (27.3±1.94 vs 24.3±1.80, p< 0.05). The most common errors included inadequate actuation time and breath holding, and insufficient activations. Conclusion : These findings suggest that patients with asthma be instructed in inhaler use and that their technique be checked regularly and repeatedly depending on education level.

사회에 만연한 정신과 진찰에 대한 편견과 거부감으로 적절한 시기에 정신건강 상담과 치료를 받지 못하는 정신질환 환자가 지속적으로 증가하고 있다. 정신과 치료를 대체하기 위해 최근 청각, 시각적 자극을 통한 자율안정쾌락반응(autonomous sensory meridian response: ASMR)이 주목받고 있으며 많은 사용자가 심리적 안정 효과를 보고하고 있다. 그러나 현재까지 ASMR의 심리적 안정 효과를 정량적으로 확인한 연구가 미비하며, 심리적 거부감과 부담이 적은 정신건강 증진 보조 시스템으로 활용을 위해 ASMR의 객관적 안정 효과의 검증이 선행되어야 한다. 따라서 본 연구에서는 임상에서 정신 건강 진단에 사용되는 심전도를 이용하여 ASMR 자극 종류와 청취 방법별 심리적 안정 효과를 객관적으로 검증하였다. 그 결과, ASMR 자극 중 속삭임 자극이 심박수 저하 효과가 있었으며, 영상을 통한 자극 청취방법을 사용할 경우 저/고주파수 파워 비율이 감소됨을 통해 심리적 안정 효과의 가능성을 확인하였다. The number of mentally ill patients who refuse psychiatric treatment at an appropriate time is constantly increasing due to the prejudice and rejection of psychiatric assessment. Recently, the autonomous sensory meridian response (ASMR) with auditory and visual stimuli attracts attention as an alternative to psychiatric treatment, and its effect on psychological stability has been reported by users. However, most of previous studies have not quantified the positive effect of ASMR, thereby there is little objective evidence that ASMR can be used as a mental health care system with less psychological burden. Therefore, the objective psychological stability effect of ASMR should be first confirmed. In this study, the psychological stability effect on ASMR with different type and stimuli method was objectively confirmed using the electrocardiogram (ECG) used for diagnosis in clinical psychology. As a result, whispering stimuli of ASMR has effect of heart rate reduction. Moreover, the possibility of psychological stability was confirmed by decreasing the low/high frequency power ratio when stimuli presented as an video.

Using several complexing agents, plating rate and plating condition of electroless Co- Cu-P plating bath have been studied. The result obtained from this experiment summarized as follow ; It was found that the optimum bath composition consisted of 0.1M cobalt chloride. 0.03M copper chloride, 0.2M sodium hypophosphite as reducing agent and 0.3M sodium citrate as complexing agent, whereas the bath of pH 10 adjusted by sodium hydroxide and 80℃ of bath temperature gave good result. The activation energy between 40℃ and 80℃ were calculated to be 48.3 KJ/mole for deposition weight. Plating reaction had been ceased by increase of pH above 11, temperature higher than 90℃ and under 40℃. Deposited surface became worse in case of the increase of bath temperature above 80℃.
