Solvent extraction and stripping experiments were conducted to separate iron from a spent FeC13 etching solution containing nickel. In the operation of mixer-settler, 7 extraction stages with 1.0 M Alamine336 in toluene, led to 98% extraction percentage of iron at equal phase ratio, when the flow rate of organic and aqueous were 35 mL/min and 5 mL/min, respectively. At equal phase ratio of aqueous to organic, 10 stripping stages with 0.01 M HC1 solution resulted in 99% stripping percentage of iron when the flow rate of stripping solution and loaded organic were 5 mL/min and 35 mL/min, respectively. The concentration of iron in the stripped solution was 133 g/L and this solution could be reused in the etching of nickel lead frame. (Received June 15, 2004)

The purpose of the study is to clarify orange image in the modern fashion. 30 kinds of costume sample being visual power in orange have been selected from photographs in fashion magazines and divided into the tones : mist(Vp, Lgr, L), bright(P, B), vivid(S, V, Dp). The study was measured by using 27 semantic differential bi-polar scales. The subjects were 50 female students majoring in clothing and textiles, The data was analyzed using the statistical SPSS package. The data were collected using self- administred questionnaires and analyzed by MDS, Cluster Analysis, ANOVA, Sheff test and Regression analysis. The major findings of this research were as follows. 1. Evaluaion dimension of orange was classified as Feminine-Mannish, Lively-Mist. 2. There were significant difference in visual evaluation of tones. 3. The image effect on Preference, Buying needs, Pleasant and Riches was consist of complicated sensibility.

Experiments had been made to evaluate more efficient method in stool examination for various helminth ova. Authors examined 2,016 nationwidely collected stool specimens by the two methods, cellophane thick smear method and brine floatation method. The results were as foliows; 1. Of 2,019 specimens examined by cellophane thick smear method, the positive rates of following helminth ova were; Ascaris lumbricoides (fertilized) 27.3% Ascaris lumbricoides (unfertilized) 13.6%, Trichuris trichiura 39.0%, Hookworm 0.1%, Enterobius vermicularis 0.05% Hymenolepis nana 0.04%, Taenla spp. 1.3% Clonorchis sinensis 1.1% and Metagonimus yokogawai 5.7%. And, A. lumbricoides (fertilized) 27.0%, A. lumbricoides (unfertilized) 3.8%, T. trichiura 38.1%, Hookworm 2.0%, Trichostrongylus orlentalis 0.6%, E. vermicularis 0.2%, H. nana 0.8%, and M. yokogawai 0.05% by brine floatation method. 2. The causes of inferior positive rates in some helminth ova by cellophane thick smear method were shortly discussed and suggest some opinions in improvement of detection ability. 3. The positive rates of following helminth ova were superior in cellophane thick smear method to those of brine floatation method: A. lumbricoides(fertilized), Taenia spp., C. sinensis and M. yokogawai. And, the positive rates of following helminth ova were superior in brine floatation method: Hookworm T. orientalis, H. nana and E. vermicularis. 4. Cellophane thick smear method has been known to be one of the most effective methods in mass stool examination. But, this method is not so effective in detection of certain species of helminth ova. Therefore, employment of brine floatation method added to cellophane thick smear method is desirable for the better result of mass stool examination.

본 논문은 보험사기의 구조를 이론적으로 분석하는 데 초점을 두고 있다. 보험사기에 영향을 미치는 요인들로는, 법적 제재수준, 보험사기 이득의 크기, 보험사기 적발확률 등을 들 수 있다. 본 논문은 이들 요인들이 보험사기와 관련되어 어떤 관련성을 가지고 있는지, 그러고 보험사기 행위 및 선의의 보험계약자에게 어떤 영향을 미치는지 분석하고있다 결론적으로, 보험사기와 관련된 요인들 가운데 현실적으로 보험시장의 건전화를 위해 가장 핵심적인 것은 보험회사의 효과적이고 효율적인 사기적발 조사활동이라고 할 수 있다. This study focuses on the theoretical analysis of the structure of insurance fraud. Among factors affecting insurance fraud are the level of legal punishment, the magnitude of what the insured get through fraudulent behavior, and the probability of their being detected. This study analyzes how those factors are related to insurance fraud and how they affect fraudulent behavior and benevolent insureds. In summary, the most important thing to keep sound the insurance market should be for the insurers to detect fraudulent behavior both effectively and efficiently.

This study focuses on the demand for products liability insurance when the producers are faced with legal uncertainties. Unlike personal liability cases, long-term profit losses that usually are not covered by insurance contracts may be much more important to the producers. Thus, the role of the courts and the efforts to win lawsuits should be taken into consideration when we analyze the demand for products liability insurance. The results are as follows. First, the producers increase their insurance coverage as they become more legally liable for products-related accidents. This is consistent with what we see in existing insurance literature. Second, producers as insureds tend to increase their insurance coverage as much as possible in order to cope with 'a reverse moral hazard'. The insurers, when they are delegated to perform the lawsuits, may have private incentives not to do their best to win the lawsuits, because they want to minimize the sum of insurance payment and the legal costs. This is called 'a reserve moral hazard', and an effective way to control it is to make them more affected by the results through more insurance coverage.

This study analyzes how organizational structures of insurance companies could affect agency coats and, thus, the form of executive compensation. Theory predicts that incentive compensation relies less on performance measures as they are more easily affected by managerial discretion. Using the American life insurance data, this study attempts to test the hypotheses that mutuals allow more discretion to their executives, and that companies with more dfficers on the board of directors have more difficulty in monitoring and controlling company operations. In general, the results from preliminary tests do not support the test hypotheses. It suggests (1) that there may not exist meaningful cross-sectional difference in the degree of managerial discretion between mutuals and stocks, given the validity of the statistical tests, or (2) that the power of the tests may be too weak to find the difference there exists in the real world.
