  • The main purpose of this study was to clarify the validity with patient's general background of Korean Pain Measurement tool. The subjects of this study were 195 patient from the 8 Med-Surgical wards in H. University Hospital in Seoul. The study was conducted over a 40 day period from Oct. 5, 1985 to Nov. 15, 1985. All patients had pain. Korean Pain Measurement tool and simple discriptive pain scale as Graphic Rating Scale were used to measure the pain, The Pearson Correlation Coefficient test was exercised to measure the correlation between the two kinds of pain tools. To clarify the Sensitivity of Korean Pain tool was used frequency with patient's response. To compare the difference in Pain levels with patient's general background, ANOVA and t-test was employed. To compare the difference in pain levels existed due to pain area of the body used mean numbers. The outcome of the study was as follows : 1. A positive correlation did exist between two pain measurement tools. (r=.2028∼.7768, p <0.002) 2. The sensitive subclass in Korean Pain Measurement tools was 7 subclass. The 7 subclass are inflammatory repeated pain, simple stimulating, traction pressure, dull pain, cavity pain, digestion related pain, suffering. related pain. 3. The existence of levels of pain in accordance with patient's general background, the department of hospital, pain area of the body and school age was supported. Age, sex, religion, marrital status, economic status, acute or chronic status was not supported. 4. The existence of higher pain levels of the body area was anus, chest, and lower pain levels of the body area was eye, ear, nose and throat. Based on the above results, it was found that sensitive subclasses of the Korean Pain Measurement tool was 7 subclass among all of 20 subclass. Thus it can be concluded that Korean Pain Mea-surement tool when partialy used and supplemented, can be an effective tool of pain measurement for the patient in Korea.

  • Objectives For successful adoption of legislation controlling registration and assessment of chemical substances, it is important to obtain sufficient toxicological experimental evidence and other related information. It is also essential to obtain a sufficient number of predicted risk and toxicity results. Particularly, methods used in predicting toxicities of chemical substances during acquisition of required data, ultimately become an economic method for future dealings with new substances. Although the need for such methods is gradually increasing, the-required information about reliability and applicability range has not been systematically provided. Methods There are various representative environmental and human toxicity models based on quantitative structure-activity relationships (QSAR). Here, we secured the 10 representative QSAR-based prediction models and its information that can make predictions about substances that are expected to be regulated. We used models that predict and confirm usability of the information expected to be collected and submitted according to the legislation. After collecting and evaluating each predictive model and relevant data, we prepared methods quantifying the scientific validity and reliability, which are essential conditions for using predictive models. Results We calculated predicted values for the models. Furthermore, we deduced and compared adequacies of the models using the Alternative non-testing method assessed for Registration, Evaluation, Authorization, and Restriction of Chemicals Substances scoring system, and deduced the applicability domains for each model. Additionally, we calculated and compared inclusion rates of substances expected to be regulated, to confirm the applicability. Conclusions We evaluated and compared the data, adequacy, and applicability of our selected QSAR-based toxicity prediction models, and included them in a database. Based on this data, we aimed to construct a system that can be used with predicted toxicity results. Furthermore, by presenting the suitability of individual predicted results, we aimed to provide a foundation that could be used in actual assessments and regulations.

  • The main objective of this study is to develop an discrete optimization algorithm of plane steel frames with rigid using second-order-elastic-plastic hinge analysis which is considering panel zone. Conventional analyses of steel frame are usually tarried out without considering the effect of panel zone deformation on frame behavior The validity of this model is established by comparison without panel zone on joint models is analyzed numerically to demonstrate the importance of using realistic models in steel frame analysis. The objective function is taken as Weight of steel frames and the constraints we formulated based on AISC-LRFD(1994). The validity of the developed algorithm we demonstrate by comparing the result with those of SAP2000. The result of the study indicates that the optimal design algorithm considering of panel zone behavior more economic design than simple steel frame design methods.

  • This study is designed to evaluate the contents of the separation of prescribing and dispensing roles(SPD) policy based on the theoretical backgrounds. The results are as follows; Considering the purpose of SPD policy, 'increasing the efficiency in manpower management by separating the role of medical doctor and pharmacist and improving the quality of SPD service through specialization of function' as a policy objective is valid and very important agenda in health care. But the objectives are not working well by no keeping the detail means to actualize it. Also, some policy objectives are unclear or inappropriate and it makes the focus of that policy obscure or misleads inadequate policy alternatives. In terms of means of policy, it is evaluated to have some limits in effectiveness, efficiency, equity, rationality, technical feasibility, economic feasibility, administrative feasibility, social and time feasibility. In conclusion, it's necessary to investigate the some problem mentioned in this paper with empirical evidence. Also, it should be needed to improve the validity of policy by correcting policy objectives and means in execution of policy.

  • Residential segregation is often considered to be one of the social problems that intensify urban inequality This study reviews three different frameworks about the causes of residential segregation and tests their validity in the real world. The review focuses on racial/ethnic residential segregation in U.S. cities since it has been blamed for persistent socio-economic gap among racial/ethnic groups. The three different segregation frameworks include 'spatial assimilation' that attributes segregation to low degree of assimilation and acculturation, 'place stratification' to discriminatory practices in the housing and mortgage markets such as steering, blockbusting, and redlining, and 'resurgent ethnicity' to racial/ethnic preference in residential choice, particularly in-group attraction. As an effort to test their validity, the paper examined residential pattern changes of the four major Asian nationality groups through 1990s and found that their residences got decentralized but re-cluster in some selected suburbs. This supports 'resurgent ethnicity' largely and 'spatial assimilation' only partly.

  • Purpose: A new scale was developed to measure personal power and ability for health care and promotion including health determinants. Method: Research phases designed for this study were a literature review, scale development, discussion with experts, pre-test for content validity, and survey for construct validity and reliability. The scale was composed of 20 items on 4 point Likert scale and was tested on middle aged Korean-Americans (110) and Koreans (105) living in a community. Result: As the result of factor analysis, 7 dimensions were identified that were similar yet different from the original dimensions. They included health literacy, socialbelonging and gender role, self-perception, health policy participation, socio-cultural interpersonal relationships, spiritual comfort, and socioeconomic involvement. The total variances explained 59.73%. The reliability was .736 of Cronbach's alpha. The mean PPHC was not different in age, gender, economic status and disease presence, but significantly different in country where living, religion, education level, job presence, and emigration period. The increased power group perceived more wellbeing and less depression, high internal locus of control and increased power with others. In addition, they had a greater health promotion lifestyle profile. Conclusion: This scale was statistically reliable and valid to measure personal power of health care.

  • Self-sufficiency of the female victims of prostitution has been understood as a 'result' at a particular moment focusing on an economic self-sufficiency. Overcoming such limitation, this study originates from a problem posing that evaluating self-sufficiency of the female victims of prostitution should be approached as a series of 'processes' in which experiences of the victims are integrated. The methodology of the study included a questionnaire survey with questions designed based on the self-sufficiency experiences which were analyzed through an in-depth interview with 34 female victims of prostitution. The questionnaire survey was conducted with 243 female victims of prostitution, and construct validity and reliability were verified. As a result of an exploratory factor analysis, a validity of scale in four factors and 24 questions was verified. A reliability of each factor was high ranging from .823 to .871. It could be achieved to make a relatively invisible process of self-sufficiency visible by developing the scale. Subsequently it complements the existing concept of self-sufficiency and overcomes limitations of measuring its results, hence reflecting the reality of the self-sufficiency practices.

  • In this paper, a temperature and humidity algorithm was proposed to enhance the economic efficiency and productivity of smart farm. The basic conditions of smart farms were analyzed, and the information exchange system between sensors and control objects in smart farms based on wireless communication was designed. Based on this, a temperature and humidity control algorithm was developed so that temperature, humidity and soil humidity within smart farm can be followed in predefined values for plant growth. To verify the validity of the proposed design methodology and control algorithm, a prototype of small scale smart farm based on 2.4GHz wireless communication were built and their validity was confirmed through repeated temperature and humidity test.

  • The aim of this study was to develop a scale of the Korea citizen's intentionality out of their inborn ability and mission. To set up the concept of the above intentionality, there have been many academic and religious studies for reference in addition to the existing productivity, Korea elderly successful aging scale, and the scale of life qualities for review. The first 57 items for questionnaires were created thereafter. The final 27 items were confirmed, which were constantly modified by a professor of statistics and corresponding author in effective response and in removing the redundant items after the first items had been reduced to 44 preliminary items through the many an item-by-item discussions with pastors, theologians and social workers. A survey was conducted around the metropolitan area and 380 records were collected. Factor analysis to verify the validity of the measurement tool was completed, and showed that there were 6 sub-factors; "recognition of being", "autonomous life", "self-completion", "initiative", "acceptance", and "economic feasibility". In addition, reliability analysis was implemented and found to be reliable because the Cronbach's ${\alpha}$ value was 0.6 or more.
