Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

The further building industries are required to include the economic aspects and the environmental aspects simultaneously, where the assessment of these two areas make it possible to select the proper alternative at planning stage. In various assessment ideas in planning process, the estimation of the energy consumption, CO₂ emission and SO_x emission could be effectively utilized to compare and analyze the environmental influence within various alternatives. In this paper, it aimed at providing the unit of energy consumption, CO₂ emission and SO_x emission as an assessment item in according to the structural type of the residential complex building and comparing the environmental impacts at the Steel Reinforced Concrete and Reinforced Concrete. This study found that Steel Reinforced Concrete is better than the RC type building in energy consumption. But SRC is a little unfavorable than the RC type building in CO₂ emission and SO_x emission.

New gold colloidal film sensor chips were employed to enhance the sensitivity of the Surface Plasmon Resonce (SPR). Au collodal solutions were synthesized, and Au colloidal films were fabricated by immobilization of colloid on vacuum deposited Au film through the coupling agent of 1,8-diaminooctane. Specific interaction of human IgG antibody to human antigen was monitored by in situ SPR measurement from both a smooth and a Au colloidal films. Au colloidal film sensor chips resulted in 27 % enhancements effect for the same reaction on SPR angle shifts compared to a smooth Au film.

The research on surface modification technology has been advanced to improve the properties of engineering materials. Ion implantation is a novel surface modification technology to enhance the mechanical, chemical and electrical properties of substrate’s surface using accelerated ions. In this research, nitrogen ions were implanted into aluminum substrates which would be used for mold of rubber materials. The composition of nitrogen ion implanted aluminum alloy and nitrogen ion distribution profile were analyzed by Auger Electron Spectroscopy (AES). To analyze the modified surface, properties such as hardness, friction coefficient, wear resistance, contact angle, and surface roughness were measured. Hardness of ion implanted specimens was higher than that of untreated specimens. Friction coefficient was reduced, and wear resistance was improved. From the experimental results, it can be expected that ion implantation of nitrogen enhances the surface properties of aluminum mold.

Objectives : To investigate the nature of emotional responsiveness in norma) adults, we exam the emotional responses to emotional pictures in an evaluative space defined by arousal and valence. Methods : Subjects were instructed to rate the arousal and valence that they experienced from the presentation of one of two sets of 60 emotional pictures. These two picture sets were comprised of 107 pictures : 101 selected from Intetnational Affective Pictures System and six pictures from our own collection. According to "evaluative space model", the authors set an evaluative space defined by the arousal scores as independent variable and the valence scores as dependent variable. In this evaluative space, one-hundred-and-seven pairs of coordinates representing respective emotional pictures were plotted. With regression analyses, the steepness of the regression lines on the plots with positive emotional responsiveness (n=51) and those with negative emotional responsiveness (n=56) were compared. Results : In the evaluative space, the regression line of negative emotional responsiveness was significantly different from that of positive responsiveness. The slope of negative responsiviveness was significantly steeper than that of positive responsiveness. At a low arousal level, the absolute valence of a positive stimuli was larger than that of a negative picture. Conclusion : This finding indicates that the function of the negative affective responsiveness might be different from that of the positive responsitiveness. IAPS also seems applicable to Korean subjects.

404 nurses and nurse-aids rated their experiences of 45 symptoms(Moos' Menstrual Distress Questionnaire) of the menstrual, premenstrual and intermenstrual phase on a 4 point scale separately. The 45 symptoms were inter-related and factor analyzed separately for each phase. six common clusters of symptoms emerged from 3 phases, which were labeled concentration, motor tension, pain, pleasurable affect, autonomic reactions and water retention. Four clusters of symptoms emerged from premenstrual phase. These clusters were labeled instabillity, withdrwal reactions, depression and headache. The factor named unpleasurable affect emerged from intermenstrual and menstrual phase. Above findings were differed from the results of Moos' study in which eight basically replicated clusters of symptoms emerged from three phases. Through discussion of validity of this scale, and differences between results of Moos' and this study, we came to the conclusion that sampling of subjects, prospective longitudinal symptoms reporting, amount of variance in a symptom over the course of menstrual cycle and proper choice of factor analysis method would be salient variables to construct valid scale for measuring menstrual cycle symptoms.
