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.

The purposes of this study were (1) to analyze students' reasons, for applying to the Teachers College, department and major; (2) to assess the degree of satisfaction on being assigned to their particular department; (3) to investigate their attitudes toward the new way of assigning students in terms of two broadly classified majors i.e., studies of humanistic and social sciences and studies of natural sciences; (4) to estimate the degree of fulfillment of student desire and degree of utility of physical facilities; and (5) to identify reasons of success or failure of the students in the respective departments they were assigned to. The subjects were 2 groups of Teachers College students, one group which entered the university in 1976 and the other in 1977. In order to collect data pertaining to students' opinions or attitudes, questioniares were used; the score on college entrance exam and grade point average were obtained from individual student reports. The data were statistically analyzed by means of either Z or chi-test. The major findings were as follows: 1. Approximately 41 percent of the freshmen of the Teachers College reported that they decided to enter the Teachers College in order to be teachers. 2. Approximately 70 percent of the Teachers College students decided their particular major by themselves rather than by suggestions or advices. 3. The degree of satisfaction on having entered the Teachers College was relatively high, since the average scale point was .472. 4. The fresh students showed a significant decrease in their positive attitude toward the new way of assigning the students to the department or majors. The average scale point of the students in 1975 was .276; that of in 1976 was .489; that of the students in 1977 was .077. When the changes in attitude toward the new way of assigning students to departments or majors were estimated, it was observed that the degree of those in favor was .489 at the beginning of the first semester, and-.677 at the end of the second semester. However, the degree of satisfaction reported by students after they were assigned to a specific department or major was .732. Therefore, the negative attitude toward the new way of assigning could be interpreted as a reflection of students' anxiety status of rather than an attitude against the new way of assigning the students.

Japan), and leg strength(180/sec, 30/sec.), power, isometric maximal strength, and endurance were measured through Cybex-Ⅱ system. After pre-test, exprimental group was begin to intake Gin-Seng for eight weeks, and control was start to reduce their body weight. As the results of the study, conclusion to be drawn as follows; 1. There were no significant difference between before weight reduction and after weight

物價變動會計 導入方案에 관한 硏究

The objective of financial reporting is assumed to provide informations regarding a firm's transactions and resources, which should be relevent to the making of economic decisiona by many persons or organizations inside and outside of the enterprise. The information of accounting should be useful in decision making but conventional historical cost acounting couldn't be relevant to this objective in current inflation period. The conventional historical cost accounting would be agreed on the assumption of a stable monetary value. There are some of problems in regarding the conventional accounting. First, historical cost accounting couldn't measure and communicate current values of corporate's assets and income. Second, the measurement of income is not relevant to information's users and rational in theoretical structure. Price-level changing has modified the meaning of income measured in terms of historical amounts. The income measured in terms of historical cost is consist of current operating income and earning by price level changing but it can't measure and communicate them separately. It is very difficult to maintain physical capital because the period income determined by matching historical cost and current revenue causes unadequate income tax and dividend. Now we are in the environment of changing prices. The conventional accounting couldn't provide the relevant information to the persons and organization inside and outside of the business no more than. In December 1974, the Financial Accounting Standards Board released on Exposure Draft which would have required supplementary financial statements prepared by a comprehensive restatement in terms of general purchasing power. In 1976. the Securities and Exchange Commission issued Accounting Series Release No. 190 requiring supplemental disclosure of the replacement cost of fixed assets and inventories for large corporations. In the United kingdom a government-sponsored committee (Sandilands Committee) on inflation accounting proposed that the historical cost accountng system should be scrapped and that current value accounting (primarily current replacement cost in practice) should be substituted. In 1980, FASB proposed supplementary statement that contains restating financial statement based on historical cost by general price-level and disclosing information of current replacement cost about the inventories and fixed assets. As you know, there are two kinds of inflation acounting models; general price-level accounting and replacement cost accounting. The latter is more relevant and reasonable than the former in accounting theory and the usefulness of informations. Replacement cost accounting has two major advantages in the presentation of significant financial information. First, the statement of financial position, under historical cost accounting, loses its economic significance when large price movements have rendered historical valuations virtually meaningless. But replacement cost valuation, however, does reflect the effect of changing price. Thus, replacement cost accounting generates a meaningful position statement. Second, because operating incomes are clearly separated from holding gains in replacement cost accounting system, it discloses more relevant information than the convention historical cost income statemennt. The efficiency of operations can be evaluated through referring to current operation income, and the effects of price changes are clearly identified as realizable cost savings which were either realized during the year or remain unrealized at the end of year. The flow of revenues, costs and cost savings in replacement cost accountings are as following: ?? I suggest that replacement cost accounting should be adopted urgently in Korea that has suffered serious inflation. In order to adopt inflation accounting in Korea, the followings should be set forth beforehead. First, Korean Acounting Association, the organization of accounting professors, or Korean Institute of Certified Public Accountant should suggest a public opinion about inflaion accounting. Second, accountants of firms should be reeducated of inflation accounting by accounting professors. Third, computers must come into wide use in almost of corporations to resolve the enormous operations of accounting. Forth, the policies of income tax and dividend must be changed. The base of income tax or dividend must not be corporation income (realized income) but current operating income.

The purpose of this article is to research kick patterns in taekwondo game. The research is based on the international taekwondo game held by KBS broadcast in 1994 where 12 countries attended. In the games the frequency of kick showed high in frequency and score rate. Back kick, front beat kick, back beat kick, and chop kick was not so high as front turning kick in frequency and score. But there was no statistical significant in these kick patterns. Attack in advance and counterattack also showed different scores and score rate. The frequency of counterattack showed statistical significant in kick patterns. So we need to develop kick techniques and scientific programs for a high score and for an effective game.
