  • The types of test items which were recorded in this test report of quality control domestic $^{18}F$-FDG radiopharmaceutical which consisted of 13 different types: appearance, half-life, radioactive heterokaryosis, radiochemical Confirmation (measure of Rf value), radiochemical Purity, Ethanol, Acetonitrile, Kryptofix, Aluminium, pH, Endotoxin, aseptic test, and radioactivity${\cdot}$ml-1. The record was fully recorded in 'appearance', 'radioactive heterokaryosis', 'pH', 'Endotoxin', and 'aseptic test'. In 'half-life', 'radiochemical Confirmation (measure of Rf value), 'radiochemical Purity', 'Ethanol', 'Acetonitrile', 'Kryptofix', 'Aluminium', 'radioactivity${\cdot}$ml-1', there were differences in records of each manufacturing business on radioactive medicine and medical supplies. The result of the test showed all 13 items of quality control test were 100% suitable on the basis of recorded data. There were more radiopharmaceutical made in the laboratory than in hospitals and businesses and in for result of suitability test, the laboratory showed higher suitability than did the hospitals or businesses. Domestically, there are differences of the test report items in the safety of radiopharmaceutical of each facility, and since it is not standardized, supplements are needed. To submit standardized test reports of quality guarantee in radiopharmaceutical, GMP of U.S. and CE Mark of Europe should be referred as well as receiving advice from professionals to standardize as suitable domestic standard.

  • The scores of TOEFL, TOEIC and TEPS have been increasingly used for many purposes in Korea In particular, these test scores are being used as a measure of the test-takers' overall communicative competence. Nonetheless, few studies have been conducted that investigate the validity of the test scores used for this purpose. As a preliminary step to explore the validity of the test scores, we conducted a small scale study by comparing 30 university students' scores in TOEFL, TOElC and TEPS with their class performances in English conversation and composition courses. The correlations between the test scores and the grade point averages of the courses show that the test scores are much harder to use as a valid measure of test-takers' overall communicative competence than usually thought to be and that the score in TOEFL is, nonetheless, a more reliable measure than the ones in the other tests. Although tins study has a few limitations such as the small number of participants, the homogeneity of the sample as a group, etc, it provides some insight into the use of the three tests for measurement of overall communicative proficiency and suggests need for conducting further validation studies in these areas.

  • The use of non-bearing light weight wall has increased recently due to the increase of high-rise buildings and supply of long-life housing. Light weight wall has advantages such as reducing the self-weight of the building, convenience in installation, and shortening construction period, however, must have a sufficient strength to external force. This study standardized the impact resistance test method for light weight walls by using the actual impact load obtained through load analysis test in previous studies. The impact resistance test method was divided into the test method that uses soft body and the one that uses hard body. The size of specimen was set up as height 2.4m and width 3.0m. The size and shape of the body followed those used in BS 5234-2 and so on for the compatibility with the test method used overseas. The judgment criteria for impact resistance based on test results were not defined uniformly as the assessment of functional damage can vary depending on the type of material, structural method, purpose of wall, and so on even when the same impact load was applied.

  • This study was developing group counseling program for sexual education for Christian young adults. and its effects were proven. For this purpose, this study of unmarried Christian young adults ranging 30 from the age 20~35 years old who are attending church C and S located in city of C at Kyungnam province. The subject and control group each had 15 people who separately participated in this program once a week for 120 minutes, 12 times in total. The control group did not receive any feedback after the sessions. group counseling program for sexual education was based on Crabb's biblical counseling model and McMinn's cognitive therapy. Using 12 kinds of cognitive therapy techniques. for its effects were verified. used The sexual knowledge scale standardized model of a college student set by Jeon Gyungsook, Lee Hyoyoung, Lee Seonja, The sexual attitude scale standardized model for a college student set by Ho Seonmin, The sexual decision making scale developed by Sun Mikyung. The data analysis consisted of Cronbach's α test, χ2-test, Mann-Whitney U test, Friedman test, a χ nd Wilcoxon signed-rank test. The result of this study is improve the sexual knowledge, show the conservative tendency of sexual attitudes, and prove the increase in the ability to make responsible sexual decisions of Christian young adults. Following up, this study spreads awareness of the true meaning of sexual being as illustrated from the bible and implies a beneficial program within the church that promotes a healthy life and reconciliation between self, neighbors, and God in a life according to the purpose of creation and order.

  • Wetlands are generally thought to be among the most fertile and productive ecosystems of the world. They provide a variety of ecological functions to the landscape. In recent years there has been considerable research activity to generate more scientific documentation on the ecological functions of wetlands. Many pollutants released to the environment settle and accumulate in the silt and mud called sediment on the bottoms of wetlands. Contaminated sediment can cause adverse effects to aquatic organism and eventually to ecological system. Sediment toxicity test with water fleas has been done by standardized preparation method of pore and elutriate water methods described in the literature for the need to protect Woopo wetlands. The results of Daphnia magna, Ceridaphnia dubla and Simocephalus sp. toxicity test were compared and discussed in terms of the relative sensitivity and discrimination abilities with both pore and elutriate water obtained from the sediments of Woopo wetlands.

  • Since HLA (High Level Architecture) was selected as a standardized distributed simulation architecture by US DoD in order to guarantee interoperability among all types of simulations, weapons system and C4I systems, to improve reusability of developed models in mid 1990s, a large number of federates have been developed and certified in accordance with HLA specifications. This paper illustrates case studies on HLA compliance test which are helpful for developers and managers. Based on experiences obtained from international HLA compliance test of CJ21_NG being developed for ground warfare simulation during ROKA's BCTP and UFL exercises, compliance procedures of US Defense and Modelling Simulation Office (DMSO) are introduced, and detail information at each phase of compliance test is provided.

  • The three-axis road simulator is the test equipment which can simulate the standardized road conditions for the durability evaluation of automotive components such as suspensions. The road load data are collected and acquired from a vehicle test, and then these data are used to simulate road load conditions by the road simulator which consists of hydraulic actuators, link mechanism and servo controller. The link mechanism must be designed in consideration of the dynamic effect and interference during three axes motions in order to generate accurate motions. In this paper, the structural and kinematic analysis of the link mechanism is performed, and these results can be used for developing the three-axis road simulator. The three-axis road simulator provides considerable savings in cost, development time, and testing risk during developing automotive components.

  • Utilizing of the geotextile container shows several advantages such as standardized construction, factory manufactured products, the control of quality, workability, and economical point of view. Recently this technique can be applied to rehabilitate the loss of rail roadbed due to the heavy rainfall. In this study, a large-scale laboratory test were conducted with simulation of static performance on the geotextile container reinforced rail roadbed. Based on the laboratory test results, the vertical pressure distribution with respect to the depth, and settlement of rail roadbed were measured and compared test results between geotextile container reinforced case and unreinforced case. Thus, the effectiveness of reinforcement was evaluated in terms of its performance and stability.
