This study is intended to present the development methods to diversity the development strategies of the real estate appraisal business as part of the real estate business management strategies coping with a changing environment of the real estate market. The development of a new market for the property appraisal business as well as the extension of the existing business scope will be a constructive way to set the property appraisal business firmly established in its sphere of influence and to secure a competitive edge under the present circumstances where the market for its contemporary business has been saturated. And such strategy can be carried out as a diversification plan for the property appraisal business, effectively coping with a paradigm shift in business activities in real estate. For this reason this study centers on the understanding of the problem situation as to the contemporary findings of the study and institutionalized policies. However, such diversified strategies of the property appraisal business development plan included many of normative and disjunctive suggestions, and simply listed them, as it dealt with too varied topics. It is therefore suggested that more positive and an in-depth study on the various topics be conducted in the future.

Court auction of real estate stuff have many rights and the right realationship is complicate twisted so if rights analysis got wrong, no matter how cheap stuff it is you could loss ownership or property rights may be restricted so more professional knowledge about auction rights based on a thorough analysis before the auction bidding is required.

The compressor has one of important roles in refrigeration cycle and it determines refrigeration efficiency and quality. This paper aims to monitor rotary compressors for room air conditioners by using Acoustic Emission(AE) technique. The reliability of rotary compressors has been evaluated through visual inspection on them after long term test. This paper describes methods for acquisition and processing AE raw signal to monitor the state of rotary compressor. A detecting method of abnormal compressor in real time is suggested and special-purpose monitoring system which can be applied to automatic manufacturing line is developed using one-chip microprocessor at low cost.

Defocused CO_2 laser beam irradiation strengthening of 60kgf/㎟ grade steel sheet was investigated to obtain the tensile strength similar to that of fully penetrated one by the focused beam. The melted line width by the defocused beam was 3∼4 times larger compared to that of the focused beam. However, the increase of tensile strength with 1 line irradiation by the defocused beam was similar to that of 2∼3 lines by the focused beam. The increase(37.6%) of bending strength with 1 line by the defocused beam was higher than the increase(12.9%) of tensile strength. Also, the effect of cooling gas to strengthening was observed.

This paper develops an inventory model with partial backorders considering both inflation rate and discount rate under the situation of deterministic demand and lead time and then make an economic analysis. Especially, the inventory model with partial backorders provided here is the inventory model minimizing annual total cash outflows, which is extended by the addition of inflation rate and discount rate into "Inventory Model with Partial Backorders" of Park[6]. An iterative solution procedure is developed to find an optimal inventory policy. To provide guidelines for economic analysis of inventory model with partial backorders, sensitivity analysis for selected values of parameters is performed.

Now a day, the more Proportion of concrete used in practice is exposed to serious chemical attack Chemical reactions that involve formation of expansive products in hardened concrete can lead to certain harmful effects. In this study, it is to compare and investigate the chemical resistance of natural and recycled aggregate concrete by attacked Na₂SO₄according to W/C ratio. The result of this study is that the chemical resistance of recycled aggregate concrete is lower than natural aggregate concrete. But it is developed the chemical resistance by decreasing the W/C ratio.

This paper empirically investigates the announcement effect of overseas equity related securities issuance by the 336 Korean firms between 1992 and 2001. After we reviewed the performance of overseas securities issuance firms from the existing literature, we collected data from the Korea Stock Exchange. The research was conducted by an event study. Specifically, abnormal returns are calculated by market model with parameters estimated over the 190 trading days before the event period. For each case, average abnormal returns and cumulative average abnormal returns are calculated by using daily stock returns obtained from the KSRI-Stock database. We also analyse the relation between cumulative average abnormal returns and the change of overseas securities issuance restricts, issuing size, growth opportunity by cross sectional regression. The results of this study can be summarized as follows. First, the announcement effect of overseas securities issuance is indistinct. Second, there are no particular differences of the announcement effect among overseas securities issuance firms. Third, issuing size is confirmed as a significant variable explaining cumulative average abnormal returns.

プレビッシュ命題と国際価格決定に関する再考

Prebisch에 의해 신고전파무역론에 대한 의문이 제시된 이래, 에마뉴엘, 아민, 에반스 등에 의해 「不等價交煥論」으로서 신고전파무역론에 대한 비판이 이루워져 왔다. 또한 Steedman, Metcalfe, Mainwaring, 高增明씨들에 의해 상품의 생산 기간이 다를 때, 혹은 자본을 생산수단으로 생각할 때는, 리카도의 비교생산비설이나 H-O-S정리는 성립하지 않는다는 것이 밝혀졌다. 그러나, 이러한 분석들은 모두 정태적인 분석으로 경제성장, 기술진보 등의 동태적인 요인은 배제되어 있다. 따라서 현실 경제에 보다 접근하기 위해서는 이러한 동태적인 요인의 도입이 필요하다. 이 점에 대해서는 향후의 연구과제로서 분석을 해나가고 싶다. 또한 국제가격의 결정에 관한 대표적인 이론을 고찰했지만, 신고전파에 있어서는 교역국의 생산함수와는 관계없이 상대가격이 결정되고, 그에 따라서 특화한 각국의 생산함수에 의해 이윤율이 정해지기 때문에 이윤율은 교역국간에 서로 영향을 주지 않는다. 따라서 상대가격의 유리화는 무역하의 이윤율이 자급자족 경제하의 이윤율보다 상승하게 한다. 또 상대가격이 유리하게 되지 않으면 무역은 개시되지 않으며 불리화하면 무역은 정지된다. 이에 대해서 네오·리카도파의 이론에 근거하여 상대가격 및 교역조건에 대해 분석한 결과, 교역국의 생산함수에 의해 상대가격과 이윤율이 동시 결정되기 때문에 무역은, 이 상대가격의 크기 여하에 의해서 무역이 개시되거나 안되는 것이 아니라, 상대 가격과는 관계없이 무역이 전제된다. 또한 교역국의 생산함수가 상호 규정적이기 때문에 이윤율은 국제적 이윤율이 성립하고, 기술계수가 같고, 임금율이 외생적인 한, 상대가격은 생산함수가 시프트 하지 않는 한, 저임금 국가에 있어서 반드시 불리화 하고, 양국의 이윤율은 상호 규정적으로 되어 저임금 국가의 이윤율은 불리화한다.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.
