This study is a single group before-and-after study aimed to evaluate the effectiveness of additional acupuncture therapy for lung cancer patients being treated with chemotherapy. Acupuncture therapy was conducted twice a day at least for a week. The effectiveness outcome measures were the Korean Functional Assessment of Cancer Therapy (FACT-L) and the Korean Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at the baseline, discharge and four weeks after discharge, and visual analogue scale(VAS) checked daily from the baseline to discharge. Ten patients were enrolled, one patient had excluded due to acute exacerbation of lung cancer. The data of nine patients showed some improvement in all of FACT-L, FACIT-F and VAS, however, there were no statistical significance. Additional acupuncture therapy for lung cancer patients treated with chemotherapy might be beneficial to improve the quality of life(QoL) and to improve fatigue. Prospective trials with complex traditional Korean medicine interventions are needed to further investigation.

The effect of the traditional herbal medicine Yukmijihwangtang-Jahage(YJ) on the improvement of insulin resistance and lipid profile was studied using a model for non-insulin dependent diabetes mellitus, lean (Fa/-) and obese (fa/fa) Zucker rats. Yukmijihwangtang-Jahage feeding for 4 weeks resulted in a significant decrease in the concentration of plasma triglyceride in both lean and obese Zucker rats. Furthermore, Yukmijihwangtang-Jahage markedly decreased both plasma cholesterol and fasting plasma insulin, and significantly decreased the postprandial glucose level at 30 min during oral glucose tolerance test in obese Zucker rats. Although there was no statistical significance, the crude glucose transporter 4 protein level of Yukmijihwangtang-Jahage dieted obese rats tended to increase when compared to that of obese control rats. Therefore, the present results suggested that Yukmijihwangtang-Jahage may be useful in prevention and improvement of metabolic disorders characterized by hyperinsulinemia states such as non-insulin dependent diabetes mellitus, syndrome X and coronary artery disease.

Normal range has use mainly in the first phase of the diagnostic process, that is, to screen or to raise ideas about possible pathology. The traditional method of determining it is based on the probability paper or on the mean plus or minus two standard deviations. These methods are often turned out to be vague and impractical. The percentile method is adequate and flexible, though. The appropriate limit of lower and upper points should be chosen by considering medical aspects above all things and also the reliability of the range determined by the standard error. The results of normal range are interesting, strictly speaking, only for the hospital concerned. Differences exist between the normal ranges reported by various sources (Bezemer et al, 1983). It would be best to establish the normal range based on a population comparable to a group of individuals to whom the normal range is to serve as a norm.

This research is aimed at looking into the effect of the leadership of a leader of a guard martial art on majors' exercise results. For this purpose, this research selected the present students of guard science-related department as a population as of the year 2008, and finally used the data from the 259 questionnaires collected mainly from the first-year students to the third-year students among the man & woman majors in Taekwondo at colleges across the country by using convenient sampling. To achieve research results, this research set a statistical significance level at $\alpha$=.05. A guard martial art leader's positive leadership can help Taekwondo majors improve their exercise results, so a leader is encouraged to show a leadership pattern having respect for objective, reasonable majors in tune with the paradigm of swimming with the stream of times rather than a traditional leadership pattern-lopsided communication. In addition, Taekwondo majors' potential for growth could get bigger, and visible results could also increase when a leader makes a positive effort to induce majors into making definite suggestion of their vision and growth at an all-inclusive viewpoint.

Numerical method of nonlinear regression was introduced to characterize grain-size distribution more effectively than using the traditional textural parameters. This technique proved critical particularly to multimodal size distributions, as exemplified by samples from Cheju strait continental shelf. Grain-size analysis of samples collected from the Cheju Strait continental shelf reveals that 86% of the grain-size distributions are multimodal. As multimodal grain-size distribution deviates from the statistical (log) normal distribution, the grain-size parameters traditionally used in sediment studies do not describe the distribution efficiently. Therefore, the use of grain-size curves into elementary normal component curves was used. Means and standard deviations of 387 decomposed normal components were decided by a decomposition method (nonlinear least square regression) from 167 size curves of the Cheju Strait sediments. The mean values of decomposed normal components show peaks at 1-3 phi and 8-9 phi size classes. The plot of mean values of the coarse fraction normal components on the map shows a characteristic and complex areal distribution. On the basis of the areal distribution of the mean values of the components and that of isopach of total Plenipotence sediment, the areal distribution of layers composing a transgressive sand of Late Plenipotence age were revealed.

In our country, cardiovascular disease (CVD) and Coronary heart diseases (CHD) are the leading causes of death. It is well known that CHD is multifactorial, involving environmental factors such as diet, level of exercise and cigarette smoking, and inherited factors. According to the statistical data in 2003, the cause of death with the highest mortality was including hypertension, ischemic heart disease and atherosclerosis, which accounted for $24.7\%$ of total mortality. In spite of, there have been few study reports on the change of biochemical markers and mechanisms concerned. The development of biochemical markers is required for an early diagnosis and treatment of cardiovascular diseases that are related with dietary habits of Korean people enjoying mixtures of traditional dietary style and westernized food-styles. Therefore, the most efficient cost-saving biochemical marker was established in this study, through analysis of biochemical markers related with dietary habits which are susceptibly being changed in association to cardiovascular diseases from the pre-disease phase, and through reanalysis and assessment of early diagnosis of and preventive effects of diagnosis of cardiovascular diseases by demographical character including sex, age, and socioeconomic level with use of biochemical markers that are identified and selected among the parameters in consideration of the effectiveness and appropriateness of early diagnosis of diseases. The appropriateness of biochemical markers was reviewed by professionals (medical, pharmaceutical area and food/ nutrition area) and CRP(C-Reactive Protein) and was identified to be possible in Korea. It is thought that these biochemical markers may be used as the basic data for early diagnosis and prevention of cardiovascular diseases (CVD) which may be used for Korean people.

The purpose of this study is (1) to develop native foods in the future continuosly, and (2) to provide basic information allowing college student's to correctly understand traditional culture, by investigating those college students' preference and understanding of the native foods in Cheju-do. To accomplish these purposes, the survey was carried out by use of questionaires for 344 residing in Cheju-do from 20th to 29th May, 1989. The statistical analysis including frequency, percentage, mean and standard deviation was performed by use of SAS program, while the significant difference between groups was examined by $x^2-test$. The results of this study are summarized as follows : 1. It was showed that college man had higher understanding and preference of those native foods than college women. 2. The result relating to age indicated that the more the age, higher understanding and preference. 3. The result by residing areas showed that the college students in the rural area showed higher understanding and preference than students in the urban area. 4. Based on the educational background of those subjects' mothers, it was shown that those college students of mothers having lower educational background had higher understanding and preference of native foods. 5. Those college students having good understanding of native foods accounted for 63.4 percent, while students requiring the continued development of those native foods for 91.0 percent. As a consequence, it is apparent that most subjects tended to show the positive responses to those native foods.

Methamphetamine (MA) is currently the most abused illicit drug in Korea. MA is produced by chemical synthesis, and the final target drug that is produced contains small amounts of the precursor chemicals, intermediates, and by-products. To identify and quantify these trace compounds in MA seizures, a practical and feasible approach for conducting chromatographic fingerprinting with a suite of traditional chemometric methods and recently introduced machine learning approaches was examined. This was achieved using gas chromatography (GC) coupled with a flame ionization detector (FID) and mass spectrometry (MS). Following appropriate examination of all the peaks in 71 samples, 166 impurities were selected as the characteristic components. Unsupervised (principal component analysis (PCA), hierarchical cluster analysis (HCA), and K-means clustering) and supervised (partial least squares-discriminant analysis (PLS-DA), orthogonal partial least squares-discriminant analysis (OPLS-DA), support vector machines (SVM), and deep neural network (DNN) with Keras) chemometric techniques were employed for classifying the 71 MA seizures. The results of the PCA, HCA, K-means clustering, PLS-DA, OPLS-DA, SVM, and DNN methods for quality evaluation were in good agreement. However, the tested MA seizures possessed distinct features, such as chirality, cutting agents, and boiling points. The study indicated that the established qualitative and semi-quantitative methods will be practical and useful analytical tools for characterizing trace compounds in illicit MA seizures. Moreover, they will provide a statistical basis for identifying the synthesis route, sources of supply, trafficking routes, and connections between seizures, which will support drug law enforcement agencies in their effort to eliminate organized MA crime.

The purpose of this study is to verify the hypothesis that the contents and range of library services are changed as the use of videotex systems increases. 1000 members of Chollian II were chosen as subjects for this study and the questionnaire was posted to them. The returned responses to questionnaire were analyzed with the statistical software packages 'SAS PC' and 'STATGRAPHICS'. The findings and conclusions of this study are summarised as follows: 1. Users of Chollian II make more use of videotex systems in seeking daily information than in seeking scholarly and professional information. It seems desirable to co-ordinate the services of videotex systems and libraries by redefining the traditional boundary of the two systems. Users will then conveniently get daily information through videotex servics, scholarly and professional information through the reference service of libraries. 2. Sex does not make any significant difference in the use of videotex systems. Most frequent use of videotex systems is made by those at the age of thirties. Businessmen and enterprisers make the most frequent use of videotex systems. Those of higher education are the best users. 3. As the use of videotex systems increases, use of newspapers and periodicals decreases while its increase rarely has influence on the use of library materials. 4. There is limited correlation between the use of videotex systems and that of library services. The increase of the use of videotex systems does not significantly increase or decrease the use of libraries. It changes, however, the pattern and methods of information services provided by libraries. 5. Users of special libraries make the most frequent use of videotex systems and there is not much difference in the use by users of other kinds of libraries.
