Objectives : In studying East Asia's medical classics, what must first be done before evaluating the validities of clinical grounds is the discernment of the techniques that are based on universal principles from the statements that arise from individual experience. The purpose of this paper is to discover a method of discerning the statements of individual experiences and the descriptions of universal principles. Ingredients and Methods : The paper investigates how each individual clinical experience was introduced in ancient medical classics such as Huangdineijing, Nanjing, Shanghanlun, Jinkuiyaolue, and Maijing, in the books that belong to Yian such as Canggongliechuan, Linzhengzhinanyian, Gujinyianan, and Xumingyileian, and in Korean ancient medical texts such as Eonhae-gugeubbang and Gugeubganibang-eonhae. Results : Books of precriptions and scriptures of medicine were found to include individual experiences. Furthermore, this paper's effort has revealed that the evaluation of the quality of a testimony in an ancient book must be preceded by discerning whether the said testimony is a mere personal testimony or a testimony based on the universal law of causality. Conclusions : Before conducting a clinical research of a precription contained in an East Asian medical classic, the text should first be evaluated to determine whether the prescription in question derives from clinical tests or not.

In order to conduct research on oil originated in Mongolia for further application of petroleum not only as fuel but also as raw material for organic synthesis, we need to study the physical, chemical characteristics and individual, group hydrocarbon's compositions of main petroleum fractions. A number of studies and surveys on the physical and chemical characteristics, group hydrocarbon's composition of petroleum deposits in Zuun-Bayan, Sukhaibulag, Tsagaan Elst, Tamsagbulag have been carried out earlier through n-g-M, aniline point and dispersimetric methods successfully. Yet a detailed chromatographical and NMR spectroscopic study for the individual hydrocarbon's composition of Tamsagbulag oil main fractions has not been conducted. In the present study the results of GC analyses of gasoline fractions of wells 19-3, 19-13 and 19-10, Tamsagbulag (Eastern Mongolia) were presence. The gasoline fractions of given wells were characterized by the high concentration of paraffins and presence of trace amount of olefins. There were identified 69 paraffins, 45 naphthenes, 41 aromatics and 3 olefins in total 158 individual hydrocarbons from each samples of gasoline fraction. The first attempts to classify Tamsagbulag oil under the individual hydrocarbon's composition data were successfully conducted and the supposition of a genetic classification of given oil as "sapropelic" type was made.

This study examined within-and between-individual variation in nutrient intakes in order to estimate the degrees of precison in dietary assessment among 59 female volunteers aged 21-23 years. Self-recorded 7-day dietary recalls and records were collected by during a 3 month period. Between the recall and record methods, there were little difference of within-and between-individual variations. Within-to-between individual variation ratios were > 2.0 for most of the nutrients examined, and were higher for niacin, vitamin A and C (>2.5) in the recals and for calcium, iron, vitamin A and C(>3.0) in the records. With 7-day dietary data, observed nutrient intakes were estimated to within 26-107% of the subjects' true(usual) intakes, among those vitamin C and energy showed the highest and lowest values, respectively. Correlation coefficients between observed and true nutrient intakes were 0.73-0.81 for the recalls and 0.68-0.77 for the records. In order to estimate with 20% precision, 12-13 days of dietary study were required for energy, 46 for calcium, 71-72 for vitamin A, and 199-200 for vitamin C. Attenuation factor ranged 0.73-0.81 for the recalls and 0.68-0.77 for the records. This study implies that commonly used 1 or 3 day dietary studies may not be appropriate for assessing individuals' nutrient intakes. Further research focusing on the methodological issues in the assessment of Korean diet are needed for between understanding of the relationship between diet and health in Koreans.

Purpose This study provided empirical support for the model that explain the formation of privacy concerns in the perspective of Information Boundary Theory. This study investigated an integrated model suggesting that privacy concerns are formed by the individual's disposition to value privacy, privacy awareness, awareness of privacy policy, and government legislation. The Information Boundary Theory suggests that the boundaries of information space dependends on the individual's personal characteristics and environmental factors of e-commerce. When receiving a request for personal information from e-commerce websites, an individual assesses the risk depending on the risk-control assessment, the perception of intrusion give rise to privacy concerns. Design/methodology/approach This study empirically tested the hypotheses with the data collected in a survey that included the items measuring the constructs in the model. The survey was aimed at university students. and a causal modeling statistical technique(PLS) is used for data analysis in this research. Findings The results of the survey indicated significant relationships among environmental factors of e-commerce websites, individual's personal privacy characteristics and privacy concerns. Both individual's awareness of institutional privacy assurance on e-commerce and the privacy characteristics affect the risk-control assessment towards information disclosure, which becomes an essential components of privacy concerns.

The traditional intelligent teachable system has mainly focused on knowledge and cognition. It has overlooked motivational aspects of learners. Motivation is an important factor in learning making learners to have interests in a given task and persist it. Although the systems include cognitive as well as motivational factors, the effects of ITS on interest are not equivalent depending on individual characteristics. This study is to investigate how influence learners' response patterns to their interests and also examined effects of individual characteristics on interest in teachable agent (TA). In this experiment, we used KORI which is a new type of ITS that learner teach computer agent based on the instructional method of learning by teaching'. In the beginning of experiments, metacognition, achievement goal orientation and self-efficacy were measured as individual characteristics. Then, participants were asked to use KORI at home during 10 days. After using KORI the level of interest were measured. The result showed that metacognition was positively related with interest, whereas performance goal orientation and mastery goal orientation were negatively related to interest. It suggests t hat different individual characteristics should be considered to promote learners' intrinsic motivation in TA.

For better understanding of population dynamics of Symplocarpus renifolius, some aspects of seed production were studied in natural populations for 3 years. The rate of reproducing plants (RP) was 8.06% among the whole studied. The RPs were 0.0% in leaf size class under 500cm2 per individual, and 3.6% in 500~1,000cm2, and 44.3% in over 3,000cm2. The resource allocated to sexual organ was 11.6% of total biomass at the end of growing season, and that to belowground was about 80% regradless of presence or absence of sexual organ. In the previous and the next years of seed production, the energy allocated to sexual organ didn't affect the changes of leaf size, year by year. After flowing season. Especially, a large number of sex organ were degraded in April, a period of pollination and fertilization. The number of seeds per individual was degraded in April, a period of pollination and fertilization. The number of seeds per individual was 13~22 and didn't relate to leaf size. But the weight per seed increased along leaf size per individual. Therefore, in S.renifolius population, large individual produced large seeds rather than many seeds.

This study was conducted to establish an individual identification system comprising of 19 microsatellite markers located on different bovine autosomes. The markers were typed on 257 animals from five cattle breeds. In total, 112 alleles were detected from the genotyping of 19 microsatellite markers. The average heterozygosities ranged from 0.292 to 0.824 and the polymorphic information content (PIC) ranged from 0.274 to 0.817 in Hanwoo. We found that there were differences in allele frequencies in Hanwoo when compared with other cattle breeds. The calculated cumulative power of discrimination (CPD) was 99.999% when nine microsatellite loci were used for analysis in the individual identification system. Also the matching probability, the probability that two unrelated animals would show the same genotypes, was estimated to be $0.44{\times}10^{-9}$. Therefore, the nine markers used in this study will be used for individual identification in two million Hanwoo individuals.

Individual differences in head-related transfer functions(HRTFs) were calculated using boundary element(BE) models for three Korean adults. The BE models for the individuals were developed from the computerized tomography(CT) images of the individuals. The BE models were composed of the head, pinna, and ear canal. The frequency-dependent impedance boundary conditions were imposed on the skin, hair, and tympanic membrane. The HRTFs calculated from the individual BE models showed large difference above 2 kHz in magnitude and in the locations of peaks and valleys of the frequency spectrums, which should be considered in virtual auditory sound field. The identified individual differences in the HRTFs demonstrate that the developed BE models can be utilized successfully in order to obtain the HRTFs information of individuals.

Purpose: The purpose of the study is to examine the factors that influence Korean adolescents' depression and suicidal ideation from individual, social and environmental perspectives by gender. The study used the date of the 2015 Korea Youth Risk Behavior Web-based Survey and the subjects were 68,043 middle and high school students. The levels of depression and suicidal ideation were the dependent variables and the factors influencing the dependent variables included 11 individual factors, 3 social factors and 7 environmental factors. The data were analyzed using odds ratios (OR) from multi-variable logistic regression analysis. As a result, the most significant individual factors that influenced both depression and suicidal ideation were stress and subjective happiness both in boy and girls, the most significant social factor was participation in violence treatment programs, and the most significant environmental factors were economic status, father's educational level, and whether or not they lived with their family. Therefore, programs and policies to improve adolescents' mental health should be developed considering individual, social, and environmental factors.

We examined how public social expenditure and individual socio-demographic factors affect individual voluntary activities(volunteering, giving). Hierarchical linear model(HLM) was employed to a nested data set with 37,648 individual subjects and 16 local governments in Korea. HLM analyses yield an insignificant direct effect of public expenditure to volunteering and giving, while individual factors all have significant effects on them. Finally, this study discussed why public social expenditure factor does not have significant influence in this data, and suggested policy implications for promoting volunteering and giving.
