Objectives: This study investigated the psychological characteristics of patients with functional dyspepsia. Methods: The subjects included ninety patients with functional dyspepsia and sixty four psychiatric out-patients. We administered Minnesota Multiphasic Personality Inventory(MMPI) and Illness Behavior Questionnaire(IBQ). Results: There were no significant differences between the patients with functional dyspepsia and the psychiatric out-patients by MMPI. Two groups both showed a higher distribution in hypochondriasis, depression, hysteria subscales than in any other subscales. The patients with functional dyspepsia showed lower scores in disease conviction and affective disturbance subscales in IBQ than the psychiatric out-patients. The distribution of scores of the other IBQ subscales were similar between the patients with functional dyspepsia and the psychiatric out-patients. The patients with functional dyspepsia were divided into three groups for the Multivariate cluster analysis: normal, similar to psychiatric out-patient, and severe neurotic. The severe neurotic group showed higher scores in hypochondriasis, depression, hysteria, psychathenia, and schizophrenia subscales in MMPI and showed significant different scores in affective disturbance, disease conviction, psychological and somatic concerns, affective disturbance, denial, and irritability subscales in IBQ. Conclusion: If patients with functional dyspepsia show severe neurotic behavior, such as those in, they would need appropriate psychiatric intervention.

This study investigates the distribution characteristics of medical services in Korea. For the purpose this paper examines the spatial discordance between the provisions of the medical services and the need for them, and analyzes the spatial distribution patterns of medical service in both inter- and intra-regional levels. Disclosed is a severe regional disparity problem in the provision of medical facilities at both inter-regional and intra-regional levels. In recent years people's interest gets increased more in the social well-being of the community, and the resulting strong request makes it desirable to restructure the healthcare service system. This study has thus attempted to draw out the distribution function of the medical facilities, based on the examination of the real data. A particular attention has been paid to whether there exists any hierarchical structure in their size distribution. Quite remarkably, no appreciable hierarchical structure has been observed in the scale of the medical facilities in Korea, in sharp contrast to of the three-level hierarchical structure assumed in the three-level referral system adopted widely. Remarkably, it is revealed that medical facilities in Korea are described by scale-invariant distribution functions. Instead, scale-invariant power-law behavior has been found in the size distribution, which is expected to be rather generic and applicable to other countries as well.

The development of an industry including distribution sector is influenced by not only government policy but the related firms' behaviors. Recently the large-scale retailers have had more enormous channel power than any other distributors including monopolistic makers. Now is the time for government to prepare some policies against the unfair transaction behaviors by large-scale retailers. In this paper I tried to inquire into the distribution competition policy from a political correspondent point of view related with the transition of distribution system. For the purpose of this article I compared the case of Korea with Japan. According to the results so far inquired, there are some commons and differences in the cases of the two. Some suggestions are as follows. Considering the predominant position the concept of large-scale retailers is to be extended from a single store to numerous chain stores in the political level. Government needs to examine the standard propriety for large-scale retailer; the size of selling area and amount of sales a year. When a large-scale retailer store is to be established, it need to be taken a permit or a pre-inspection. The Fair Trade Commission have to secure the neutrality from Government's strategies. And government should find out the examples of unfair transaction behavior types and prepare some proper guidelines continually. For the last time statistical data by distributors are to be fitted out and the actual investigations for estimating the effects of government policies need to be enforced.

The organ distribution study and the whole body scan were done in the albino rats at intervals of 5, 30, 60, 90 and 120 minutes after the intravenous injection of $^{99m}TC$-pertechnetate absorbed in Sephadex beads of $20{\sim}80$ micra in diameter. Effect of additional injection of physiological saline and saline absorbed in Sephadex beads of $20{\sim}80$ micra in diameter on the scan and organ distribution were also studied. The results were as follows. 1. Five minutes after the injection of $^{99m}TC$-pertechnetate absorbed in Sephadex beads of $20{\sim}80$ micra in diameter, Sephadex was well trapped in the lungs, with which the excellent lung scan was obtained. Two hours after the injection, kidneys were well visualized instead of lungs, which suggested that kidney acts as the excretory organ. Five minutes prior to scan, additional injection of physiological saline absorbed in Sephadex above mentioned was done. The bladder was also well visualized together with the kidneys. 2. In the distribution studies, most of radioactivity was detected in the lungs at 5 minutes and was gradually transferred chiefly to the kidneys and bladder and partly to the liver. 3. Additional injection of physiological saline resulted in a rapid transfer of $^{99m}TC$ trapped in the lung to both the kidneys and liver. 4. Additional injection of physiological saline absorbed in Sephadex beads of $20{\sim}80$ micra in diameter resulted in a rapid transfer of $^{99m}TC$ trapped in the lung to only the urinary system. 5. Results of these studies suggested that; a) Other nutrients and therapeutic compounds may be carried into the lungs along with Sephadex beads and then released in high concentration, which would exert greater therapeutic effect locally than that of the usual administration. b) Some radionuclides absorbed in Sephadex could be used as the lung scan agents, the flushing out of which by Sephadex-saline also give satisfactory renal and bladder scans. c) Other potent therapeutic radionuclides could be retained for some time by this method, which can be in the lungs easily flushed out within 2 hours.

Agamermis unka, a mermithid parasite of brown planthopper (BPH), Nilaparvata lugens, is the most important natural enemy of BPH and white-backed planthopper (WBPH), Sogatella furcifera in Korea. Distribution of A. unka was investigated in Korean rice fields from 1992 to 1998 and in 2001. Overwintering population of A. unka in Gosung, Namhae, and Tongyoung from 1992 to 1998 was different depending on locality and year. In the survey of A. tanka distribution in the spring of 2001, A. unka was found only at Jangheung and Haenam in Jeonnam province and Namhae, Jinju, Sancheong, Sacheon, Gosung, Tongyoung, Uiryeong, Changwon, Gimhae, and the experimental field of Gyeongsangnamdo Agricultural Research and Extension Services at Jinju in Gyeongnam province out of 30 observed regions in 5 provinces. The number of A. unka was 1,045/㎥ at Namhae, 947/㎥ at the experimental field of Gyeongsangnamdo Agricultural Research and Extension Services, and 395/㎥ at Gosung. Density of A. unka at the rice paddies of Gyeongnam province after harvest in 2001 was higher at the rice fields of Namhae, Gosung, and the experimental field of Gyeongsangnamdo Agricultural Research and Extension Services. Although density of A. unka was higher in the pesticide-untreated plots than fungicide-treated or insecticide-treated plots of forecasting paddies, there were no significant differences. After rice harvest A. unka was found from the forecasting paddies of Gosung, Jinju, Namhae and Sacheon out of 19 observed localities in Gyeongnam province.

This study was carried out targeting the intertidal zone and estuary area of Anseo port in Saemangeum reclamation zone from 2003 to 2004, to analyze how reclamation affects the distribution of vegetation and soil properties. The plant growing in these survey areas was all halophytes: the vegetation on the intertidal zone consisted of simply 3 species of halophyte, and vegetation on the high tide zone and estuary area consisted of 9 and 8 species respectively, showing a more varied aspect than the intertidal zone. As for the plant species distribution, the predominant species for the intertidal zone were Suaeda maritima, Limonium tetragonum and Suaeda japonica; the predominant species for the slope zone of estuary were Suaeda maritima, Limonium tetragonum and Aster tripolium, and the predominant species for the inundation zone of estuary were Kochia scoparia var. littorea. At the analysis result of soil chemical properties, it was discovered that the appearance of the plant species was made at some spots on the intertidal zone whose electrical conductivity(EC), $Na^+,\;and\;Cl^-$ were relatively lower. EC of between the plant species was similar in the same zone, however EC was distinctively different between the same species in the different zone. Our study found out that whether the occurrence of the plant species is possible or not was decided by the difference in soil properties. This study results suggest that the distribution of vegetation is influenced by soil environment in that the appearance of the plant species on the intertidal zone and estuary area is differentiated by soil texture and soil chemical properties.

Amp-FLP is a one of the most frequently used human genetic analysis methods which adopts STR and VNTR typings. In this study, 100 genomic DNA samples of Taeum, Soyang and Soum constitution group were analysed by Amp-FLP method. The allele distribution of three STR loci(TH01, vWA and CSF1PO) and one VNTR locus(MCT118) of each different constitution group were investigated and the allele distribution was statistically evaluated. It was found out that the allele distribution of MCT118 and THO1 loci was not significantly different among different constitutions. However, the allele distribution of vWA showed p-value of 0.02056(Soyang group) and $2.41{\times}10^{-10}$(Soum group) which is much lower than significant level of p-value 0.05. Also, p-value of CSF1PO in Soum group was found out to be $4.65{\times}10^{-17}$. Therefore, it is expected that vWA and CSF1PO loci can be used as an indicator for gnenetic difference of different constiturion if the same result is obtained with sufficient number of samples.

In this study, magnetic properties of anodized Al film deposited with ferro-magnetic metals in the capacity of perpendicular magnetic recording media were measured and evaluated to find out the role of structure and morphology of the oxide films on magnetic characteristics. The object of this work was to present the conditions of magnetic thin film formation with more superior magnetic property. Anodizing was carried out under various conditions, and then the anodized film were electro-deposited with Co, Ni, Fe and their alloys. Coercive force and residual magnetization in perpendicular direction increased as the pore length of anodized film increased. It was attributed to the increase of the amount of depoisted metals and the ratio of length/diameter of pores. Morphology of anodized films in phosperic acid was not similar to that of sulfuric acid, and thin films in the former solution had perpendcular magnetic anisostropy because of large diameter, irregular length and distribution of the pores. It was found that magnetic properties of the thin films, which had doubled layer of two metals, were dominated by the metal electrodeposited on the surface of the anodized oxide films.

This paper describes, firstly, on analytical method of computing the eigenvalues of vertical vibration of ships, taking into account for the distribution of hull weight including added mass and the effect of shear deflection and rotary inertia. The frequency equation is solved by Galerkins method into form of numerical integration. Applying the above described equation, model experiment of vertical vibration was carried out in order to varify the validity of the analytical method of vertical vibration. The model, which was made of acrylite plate, was ship-shaped wall-sided vessel with bulkheads, deck openings, and fore and after peak tank at both ends. The results of experiments carried out both in air and on water showed that the observed natural frequencies and the observed patterns of natural modes of vibration were in good agreement with analytically calculated values for 2,3, and 4-node vibration.
