Foa (1968) has proposed that inter-relationships among a set of dependent variables before and after experimental manipulation provides significant information, which must be lost when each variable is considered separately. It was assumed in this study that the inter-relationships among the responses to the objectives or the items from several related domains could be the basis of construct validity of a criterion-referenced test(CRT). The purpose of this paper is to show how the construct validity of a CRT could be examined in terms of the inter-relationships among of a set of dependent variables before and after instruction. Applying the facet theory, for analyzing and comparing structures, Foa has suggested that three kinds of behavioral changes can be defined, and all of them seem to occur empirically. The first kind of behavioral change the change of central tendency, is concerned with the spread of effect. When the effect of the experimental treatment is observed on a set of ordered variables, it may be predicted that the change will be maximal for a given variable, less strong for the variables in proximity to the first one, and still less so for variables further remote from it. While the first kind of change refers to the central tendency of the variables, the second kind is concerned with changes in the size of their relationship. Following the experimental manipulations, some of the variables may become more or less interdependent than before the experimental event. The third kind of change is a modification in order of the variables. This change may occur when certain relationships among variables increase while certain other ones decrease, so that the order of proximity of the variables is altered. If every facet and element of the CRT is properly defined, some interesting construct validity hypotheses could be derived in accordance with the Foa's approach. Hypotheses 1 : Change will be maximal for a given objective, less strong for the objective in proximity to the first one, and still less so for objectives further remote from it. Hypotheses 2 : Some or all the objectives may become more or less interdependent than before the instruction. Hypotheses 3 : The order of proximity of the objectives will be altered. In order to test hypothesis 1, suppose individuals were assigned to one of two groups ; one group receives instruction on content defined by a domain specification and the other does not. If the instruction is effective, change of the test scores in the experimental group, maximal for a given objective and less strong for the objective in proximity to the first one, would support the construct validity hypothesis. However, we should give much attention to the fact that hypothesis 1 is concerned with a "change score". Cronbach and Furby(1972) have simply suggested that the experimental problems concerning change scores could be solved in safer ways than that using the estimated change itself. The suggestion may hold true also in this case. Hypothesis 2 seems not to be sufficient by iteself. It should be specified according to domains of interest. The generalization or differentiation among objectives might be hypothesized on the basis of prior knowledge : generalization may be taken to indicate an increased relationship, and differentiation a decreased relationship. With psychomotor abilities, Fleishman(1972) has observed a phenomena similar to hypothesis 3. He found that as practice continues, the ralative importance of factors contributing to the designated objective changed significantly. If it can be predicted on the basis of prior knowledge that the order of one or more variables changes after instruction as in the hypothesis 3, which seems to be possible through domain specification, a criterion-referenced test might be developed in order that a facet design could be formulated. As described above, this study identified three kinds of behavioral changes defined logically on the basis of a designated facet and formulated construct validity hypotheses for criterion-referenced tests. Methods of testing the hypotheses and interpreting the results were also discussed. However these hypotheses are applied only to the estimated domain scores. There should be construct validation studies on allocation of examinees to mastery states, which is supposed to be one of the two main functions of the criterion-referenced test.

Bloom's taxonomy of educational objectives has been broadly applied to a variety of educational settings. including individual teacher's instructional designs. achievement tests, and nation-wide entrance examinations. However, the taxonomy has a serious flaw which has been scarcely noticed by most of educators and even educational theorists. This paper critisized the taxonomy in its logical and psychological validity. Then, this paper proposed a new approach to the taxonomy of edcational objectives, which adopted 4 classifying dimensions such as the types of knowledge, instructional environments, subjects, and learning styles.

Sparganum of Spirometra plerocercoid were obtained from naturally infected snakes(Natrix trigria lateralia) collected in Korea. The superoxide dismutase(SOD) of spargana was purified 131.2 fold using CM, DEAE-Trisacryl M ion-exchange chromatography and Sepharcryl S-200HR molecular sieve chromatography. The enzyme activity was measured(538 unit/mg of specific activity) by method of Noritaka et al.(1982). Molecular weight of the enzyme was estimated to be 33 kDa by molecular sieve chromatography and 16 kDa on reducing SDS -PAGE which indicated a climer protein. The enzyme exhibited the enhanced 6.2 times more than control(pH 7.5) activity at pH 10.0 The enzyme totally disappeared 100% at 3.0 mM cyanide while it remained 78.5% even in 20 mM azide. These finding indicated that the purified enzyme was copper and zinc containg Cu, Zn-superoxide dismutase(Cu, Zn SOD) type.

As the national income improves and thereby people's concern about health increases. it becomes essential to operate a general health examination center in the hospital. On the other hand. medical consumers patterns change much, requiring diverse health check services. In order to meet such diversifying demands. it may be necessary to investigate the current condition of health examination centers. To this end, each two of general hospitals and clinics which operated a general health examination center were sampled to be surveyed. As a method of study, the researcher visited the sample hospitals to interview with the personnels concerned and at the same time poll their opinions via a questionnaire. The results of this study can be summarized as follows; 1. As a result of comparing the scales of the health examination centers in terms of facilities, it was found that the general hospitals operate some 1.000 square-meter or wider health examination centers, while special hospitals and clinics 100 square-meter or less ones. 2. At the general hospitals, patients should wait for 6-12 months to be checked for their health conditions. But at the special hospitals or clinics, patients may only wait for 1-5 days for their health checking. At a clinic. patients can be registered and checked for their health conditions in a day. Such a difference of waiting period for health check may be attributable to patients preferences of the general hospital services. 3. More than 95% of the patients who were checked for their health at general hospitals were advised to undergo subsequent treatment, while 26-30% of the patients who were checked at special hospitals or clinics underwent subsequent treatment. These special hospitals or clinics recommend their customers to consult other eligible hospitals in case they were not capable to treat their customeres. However, they complained about the poor transfer system for patients. 4. the general hospital operate diverse special or precision health checking programs, and one of general hospital even opens a sport medical clinic where patients are checked for their health conditions periodically 3 or 4 times a year. 5. Female patients outnumbered male ones at the six sample hospital. and those in their forties numbered most. Most of the patients used a basic comprehensive health check program, and 25-30% of the patients were checked by a special and precision health check program. 6. The general hospital charge some 400 thousand Wons for their 63 kinds of basic comprehensive health check service and 300 thousand Wons for their 60 kinds of service, while the special hospital charge 220 thousand Wons for their 64 kinds of health checking services. In contrast. the clinic charge 280 thousand Wons for 63 kinds of basic health checking services and 100 thousand Wons for 50 kinds of the services. 7. All the six sample hospital own such basic comprehensive health checking equipments as blood examination and image scanning ones. However. those special and precision checking equipments are operated only by general and special hospital. and the sports medical examination equipments are only owned by the general hospital operating the medical sports clinic. To sum up, the small-scale hospital provide for poorer basic health checking system than general hospital in every terms, although the basic health checkpoints are similar. Thus, it deems necessary for those small hospital to introduce various health improvement facilities in addition to health checking ones. Lastly, it is conceived that more money should be invested to expand the health-checking and -improving facilities, while normal people as well as patients should continue to checked for their health conditions by efficient programs.

A heightened awareness of both physicians and patients as to the risk of disease transmission by blood transfusion has led to a significant increase in requests for autologous blood donation. The benefits of autologous transfusion have been well documented, but overuse of these programs could lead to inappropriate autologous donation before low-risk elective surgery. Since over collection can be costly and time-consuming and can involve some small health risk to the patient during the donation procedure, this practice needs to be avoided. On the other hand, inflexible guidelines restricting autologous blood donation could lead to undercollection, which could undo the great benefit of autologous transfusion by creating unwarranted risk through excessive exceive of the patient to allogeneic blood. It is necessary therefore to develop recommendations for the desirable quantity of autologous donation for specific surgical procedures. We have suggested the creation of a schedule of optimal preoperative collection of autologous blood at the local hospital level in an effort to maximize safety while minimizing cost. Such a schedule could also be used by third-party health care insurers in arriving at poxlicies for reimbursement of the costs associated with the collection and storage of autologous blood. In Korea, autologous blood practice is at the beginning and very primitive but the participation in autologous blood donation programs will be increased. The results of our retrospective analysis suggest that preoperative autologous blood-donation in patients planning open heart surgery are safe and effective.

This study was designed to investigate the nature of thinking styles on the self-government theory by Sternberg as an achievement variable for solving the individual difference of academic achievements in the various educational environment. To achieve this purpose, the followings were examined. First. the concepts of cognitive styles, learning styles and thinking styles should be clarified out by comparing of the definitions. characters and developing process. Second. the nature of the thinking styles should be investigated by inquiring of the relation between thinking styles and other variables including the personality types. academic achievements. self-esteem. socio-economics status and extra curriculum activities. Third. the method of instruction and assessment which was suitable to the student's thinking Styles should be given to the students for increasing the academic achievements at the classroom. Based on the major findings, the conclusions were drawn as follows: First. cognitive style and learning style were overlapped and used similarly until recently in the field of the education and training. But it would be said that cognitive styles were the subordinate concept of the learning styles and thinking styles are the unification of these styles. second, thinking styles must be one of the most influential achievement variables for predicting the academic achievements. So the accurate measure of the student's thinking styles and the method of instruction and assessment which was suitable to the individual thinking Styles should be given to the students. Third, the programs for the extension of thinking styles should be developed. Especially creative thinking styles should be improved because creative thinking styles affect the most for the academic achievements. However, it should be noted that the present study was the first of its kind, and thus it served only as an exploratory study. Not only the nature of thinking styles to academic achievements required further investigation. but also the practical study for solving the individual difference of academic achievements should be carried out in the various educational environment.

Backgrounds ; Study as to blood preservative solution is continuousely performed to prolong period of donor blood preservation which will cope with demand increase and autologous transfusion. In Korea, CPDA-1 solution, preserved 35days, substituded ACD-B(21days), is currently used for anticoaglant preservative solution of blood. But SAG-M solution (42days) were widely used in other countries for longer preservation as RBCs additive solution. Authors compared the survival of RBCs preserved with ACD-B, CPDA-1 anticoagulant preservative solution, SAG, SAGM, SAGPM and ADSOL RBCs additive solution to study changes of hematological and biochemical. Manterials and Methods ; Blood were collected from 30 healthy male donors aged 22 to 23years, for three sorts of preservative solution bag made in home (Company Green Cross. Korea) at the sametime, 5 of them were drawn into the blood bags containing ACD-B and another 5 into the CPDA-1 bags, the other 20donors were collected into the blood bags with CPDA-l, plasma was removed by centrifugation separation at 4,OOOrpm in 5minutes and replaced by 90mf of SAG, SAGM, SAGPM and ADSOL additive solution. All of blood bags were stored in blood bank refrigerator at 1 to 6℃. Samples were drawn at 1, 5, 10, 15, 20, 25, 30, 35 and 42 days in each through blood bags tubing under sterile condition used SCD(Sterile Connection Device) so as to measure changes of hematological and biochemical. Conclusion ; With the hematological and biochemical studies of red cell suspensions in six additive solution, best A TP level was seen in SAGPM and second best was ADSOL and SAGM, as seen in table 7, and lowest plasma hemoglobin was also seen in SAGPM and second best was ADSOL as seen in thble 5. For the preservation of red cells in vitro, laboratory data support SAGPM is best but SAGPM has a critical disadvantage cannot be sterilized under steam pressure. In 42 days, ADSOL and SAGM RBCs additive solution is more excellent than other solution and has merit to separate plasma from the unit blood. Therefore we concluded that ADSOL and SAGM RBCs additive solution should be used to overcome the state of imported plasma in our country.
