The objective of this paper is to verify clinical effects of Lyu's Soyosan(柳氏逍遙散) and Lyu's Kwipithang(柳氏歸脾湯). They were prescribed to the enperimental student group suffering from mental stress and annoyed by psychological instability. From the biochemical examination before and after medication, we measure the amount of hormonal variation in thyroid hormone(TSH, $T_4$) and adrenocortical hormone(ACTH, cortisol) The results are as follows. 1. The average of self-rating anxiety scale(SAS) in test group is $41.00\;{\pm}\;7.84$. This value is statistical significant and higher than one of normal person(age 20-39). The average of a global assesment of recent stress(GARS) scale is $28.62\;{\pm}9.00$. There is statistical correlation coefficient between SAS and GARS (p < 0.001). 2. Both Lyu's Soyosan(柳氏逍遙散) and Lyu.s Kwipithang (柳氏歸脾湯) groups show statistically significant reduction of total cholesterol and triglyceride level in serum lipid after ten day medication. 3. It is observed that Lyu's Soyisan(柳氏逍遙散) and Luy's Kwipithang (柳氏歸脾湯) groups have increasing tendency of TSH. The statistically significant reduction of $T_4$ was found in two groups after ten day medicaton. 4. It is observed that Lyu's Soyosan(柳氏逍遙散) and Lyu's kwipithang (柳氏歸脾湯) group have statistically significant reduction of serum cortisol level after ten day medication, Both groups have statistically significant reduction of plasma ACTH level after twenty day medication. From these results, it is verified that both Lyu's Soyosan(柳氏逍遙散) and Lyu's Kwipithang (柳氏歸脾湯) have anti-stress effects against psychological instability and mental stress. The Lyu's Soyosn(柳氏逍遙散) shows special effectiveness in depression of liver-energy(肝氣鬱結) and the Lyu's Kwipitang (柳氏歸脾湯) is also effective in deficiency heart-blood(心血不足).

Our society's modernization created many opportunities for us to need a private investigation service system. Variation of international environment due to joining in the OECD, opportunity of individual legal, collect evidence during judgement, prevention of damage criminal, security of business in company, free trade economy's system etc and don't need to enumerate how important of introduction of private investigation service system. In addition to there are lots of objection opinions, such as possibility of person's private life, invade of lawyer's area, confliction with investigation team, gap of wealth and poverty that make preponderance of information. So this research can be considerate from objective opinion, and can obtain conclusion just like below. First, private detective agencies that encroach on the individual rights will naturally deteriorate after the implementation of private investigation service system. Through this, the probability of civil rights encroachment will be lower, and for this to happen there needs to be a thorough maintenance of the system. Secondly, mutually beneficial solution should be found not by a conflict between two sides. Detective business sector should not cause social confusion from conflicts with other investigation organization such as police, or investigators, rather, it must get on the demand of the diversified citizen and maintain the diverse sector inter-cooperate right, and to do that law and institution must be made for the base. Thirdly, investigation used depending on the gap between wealth and poverty does not mean the actualization of the rights and interests of the citizen. If the duty of investigation sector is to find the evidence and collect or manufacture of the evidence, then the problems which the nation can't handle will be more enlarged and then finally end up with strengthening the capability of national public security demand.

This study was conducted to validate the semi-quantitative food frequency questionnaire that was developed to assess the intakes of fatty acids, as well as energy, carbohydrates, fat, protein, minerals and vitamins in Korean adults. The validity of the semi-quantitative food frequency questionnaire was tested on 78 subjects (31 men,47 women) aged 34 to 66 years. The semi-quantitative food frequency questionnaire included 93 food items and was validated on two 3-day dietary records. The mean intakes and the Spearman Correlation Coefficients between the semi-quantitative food frequency questionnaire and the two 3-day dietary records were analyzed for each nutrient and food group level. The mean nutrient intakes obtained from the semi-quantitative food frequency questionnaire were estimated to be greater than those of the two 3-day dietary records. The Spearman Correlation Coefficients between the energy-adjusted nutrient intakes from the semi-quantitative food frequency questionnaire and the two 3-day dietary records ranged from 0.24 for polyunsaturated fatty acids to 0.55 for fat in men and from 0.29 for polyunsaturated fatty acids to 0.55 for saturated fatty acids in women, respectively. The Spearman Correlation Coefficients for food intake ranged from 0.11 for teas and beverages to 0.58 for grains and their products in men,-0.04 for potatoes and starches to 0.73 for milk and dairy products in women. Foods consumed regularly had lower intra-person variation and tended to have higher observed correlation coefficients. These results indicate that the semi-quantitative food frequency questionnaire is a useful tool for estimating nutrient intakes, particularly of total fat and saturated fatty acid intakes.

In order to see the variation of human nature, M.M.P.I. was carried on 2, April 1992 (the last day of the second lunar month) and 15, June 1992 (the fifteenth day of the fifth lunar month). These experiments took male and female students who were in Won kwang University as subjects (108 students on 2, April, 105 students on 15, June). The results of it suggested the followings. 1) Every students' average of T-grades on each measure were in a normal scope. 2) There were no significant differences in comparison between the fifteenth day and the last day of the month. 3) On every measure except L, Mf, Si, the female students showed higher grade in the fifteenth day than the last day of the month. But there was no significant difference in male students. Both male and female students didn't show the significant one. 4) On the fifteenth day of the month, the female students showed higher T-grade then male did on every measure except Mf, Ma, Si. There was a significant difference on D, Pd, Mf(P<0.05) measure. 5) On the last day of the month, male students showed higher T-grade then female did on every measure except L, K, Hy, Pt. There was a significant difference on L(P<0.001), K(P<0.01). 6) On experiments about female students, there was no symptom of neurosis and psychosis on the last day of the month. But three of sixteen students(18.7%) showed symptom of neurosis, one of thirteen(6%) showed symptom of psychosis on the fifteenth day of the month. On experiments about male students, eleven of ninety-two(11.9%), four of ninety-two(4.3%) showed symptom of neurosis and psychosis respectively on the fifteenth day of the month. Ten of ninety-two(10.8%), six of ninety-two(6.5%) showed symptom of neurosis and psychosis respectively on the last day of the month. As the results of the above, human nature changes to some extend according to lunar cycle. And there are many changes in female than male. But it is difficult to generalize this fact by limited subject and only one experiments. So the controlled studies are needed on the basis of this result and have to take many person as a subject.

Objectives: Based on the results from the Korean Total Diet Study (KTDS), the sodium (Na) and potassium (K) intake of Koreans were estimated and compared with intake estimates from the Food & Nutrient Database (FNDB), as in the Korea National Health and Nutrition Examination Survey (KNHANES) to verify the validity of these estimates. Methods: One hundred and thirty-four representative foods (RFs) covering 92.5% of the total food intake of Koreans were selected, and 228 pairs of corresponding 'RF x representative cooking method' were derived by reflecting the methods used mainly in terms of frequency and quantity in their cooking. RF samples were collected from three cities with a larger population size in three regions (nine cities) nationwide, and six composite samples were made for each RF, considering its regional and/or seasonal characteristics. One thousand three hundred and sixty-eight 'RF x representative cooking method' pair samples were prepared, and the Na and K contents were assessed using inductively coupled plasma atomic emission spectrometry (ICP-MS). The Na and K intake of the Korean population was estimated by linking the content with the food intake data from the 7th KNHANES. Results: The mean Na and K intake of Koreans were 2,807.4 mg and 2,335.0 mg per person per day, respectively. A comparison with the Na and K intake from KNHANES, including only RFs of KTDS, showed comparable results with less than 5% variation. While the contribution and ranking of food items to Na intake were similar between KNHANES and KTDS, there were differences in K intake. This was attributed to the large discrepancies in the K content of rice and coffee between KTDS results and the values in the 9th Revision of the National Food Composition Table used in KNHANES. Conclusions: The Na and K intake of Koreans estimated based on the KTDS, which performed nutrient analysis on samples prepared to a 'table-ready' state using foods of the representative collection, was similar and comparable with that of KNHANES. This supports the validity and usefulness of FNDB-based nutrient intake estimation at the population level. The list of nutrients studied in KTDS is expected to be expanded, allowing for intake estimation of nutrients with currently insufficient or absent information in the FNDBs in use.

The purposes of this study were to assess variation of body sway prior to and after submaximal treadmill exercise; to determine the time course of the effects of a fatiguing performed on a treadmill on body sway; and to compare position sense prior to and after exercise in order to assess any variance in proprioception caused by submaximal treadmill exercise. The subjects were twenty-four healthy men in their twenties. They stood barefoot on the Kinesthetic Ability Training Balance Platform to measure body sway. Control trials were performed with eyes alternately open and closed. In the eyes open condition, they were asked to look at a target placed at eye level 1 m in front them. A total of 10 trials, each lasting 20 seconds, were performed. After this series of trials, position sense was measured. Subjects then exercised on the treadmill until 85% of each person's maximal heart rate was reached. The first series of postural sway measurements began immediately after this exercise. The second identical series of postural sway trials was performed at approximately 10 minutes after exercise. The third series was performed approximately 20 minutes after exercise. This allowed approximately 5 minutes of rest between each experimental series. Position sense was measured at approximately 15 and 25 minutes after exercise. The results were as follows: 1) There was a significant increase in body sway after submaximal treadmill exercise compared to pre-exercise values under both visual conditions (p<.05). 2) After submaximal treadmill exercise, under the eyes open condition, the mean value of body sway was significantly increased after both the first and second series (p<.05). Under the eyes closed condition, the mean value of body sway increased significantly after the first series but decreased significantly after the third series (p<.05). 3) Position sense, measured repeatedly after submaximal treadmill exercise, did not change significantly with respect to pre-exercise values (p>.05). These results suggest that fatigue induced by submaximal treadmill exercise produced an increase in body sway in young healthy subjects with or without visual input, but the increase appeared to be lasting less than 15 minutes. No significant change in position sense suggested that proprioception was unaffected by submaximal treadmill exercise-induced fatigue.

SCRIPT (Symbol/Character Recognition In Pen-based Technology) is an algorithm for on-line recognition of handwriting Hangeul. English upperacase letters, decimal digits, and some keyboard symbols. The shape of handwriting symbols has a large variation even when written by the same person. Though the feature analysis approach using a conventional decision tree is efficient, it is not robust under shape variations and prone to misclassification. Thus, a new method to overcome this shortcoming is necessary. In this paper, a feature analysis algorithm using two fuzzy decision trees which utilize the hierarchical property of the pattern is proposed. The first tree is used to represent the stroke shape, and the other tree is used to represent the relation between the strokes. since this method stores various possibilities. it is robust to shape variations and can readily modify false selections. In addition, there is a large increase in the recognition rate of high-level patterns due to low-level candidated. Experimental results show 91% recognition rate for Hangeul at the recognition speed of 0.33 second per character, and the recognition rate of alphanumerics and some keyboard symbols is 95% at 0.08 second per symbol. This is 8~18% increase in the recognition rate over th method not applying fuzzy decision trees.

A manifold is used to represent a relationship between high-dimensional data samples in low-dimensional space. In human pose estimation, it is created in low-dimensional space for processing image and 3D body configuration data. Manifold learning is to build a manifold. But it is vulnerable to silhouette variations. Such silhouette variations are occurred due to view-change, person-change, distance-change, and noises. Representing silhouette variations in a single manifold is impossible. In this paper, we focus a silhouette variation problem occurred by view-change. In previous view invariant pose estimation methods based on manifold learning, there were two ways. One is modeling manifolds for all view points. The other is to extract view factors from mapping functions. But these methods do not support one by one mapping for silhouettes and corresponding body configurations because of unsupervised learning. Modeling manifold and extracting view factors are very complex. So we propose a method based on triple manifolds. These are view manifold, pose manifold, and body configuration manifold. In order to build manifolds, we employ biased manifold learning. After building manifolds, we learn mapping functions among spaces (2D image space, pose manifold space, view manifold space, body configuration manifold space, 3D body configuration space). In our experiments, we could estimate various body poses from 24 view points.

The optimum conditions for measuring cadmium content of less than 0.2ppm by flame atomic absorption spectrophotometry were investigated. The cadmium in urine was extracted by APDC-MIBK for the analysis by atomic absorption spectrophotometry after ashing them by a wet method. 1. Optimum conditions by APDC-MIBK and DDTC-MIBK extractions. The acidic aqueous solution was prepared with appropriate amount of 0.IN nitric acid, 5ml of 25% (W/V) sodium potasstum tartarate, 10ml of saturated ammonium sulfate, and 2ml of 2% APDC(or 1 ml of 5% DDTC) chelating agent. The total volume of solution was adjusted to 55 ml and pH to $2{\sim}10$ (or$7{\sim}10$). The aqueous solution was extracted with 10ml MIBK. Concentration of Triton X-100 did not effect the absorbance for APDC-MIBK extraction of cadmium, but absorbance decreased as the concentration increased for DDTC-MIBK extraction. The sensitivity and detection limits for the cadmium determination from APDC-MIBK extraction were 0.0038ppm and 0.0102, 0.0022ppm and 0.0116 for DDTC-MIBK, and 0.0132ppm and 0.0034 for 0.1N nitric acid. APDC-MIBK and DDTC-MIBK extractions were 3 times higher than 0.1N nitric acid for the sensitivity. 2. Excretion of cadmium in 24-hour urine by APDC-MIBK extraction. Determination of cadmium in urine by atomic absorption spectrophotometry of A.A. (Cd=2 mA) mode and B.C. (Cd=4 mA) mode and B.C. (Cd=4mA, $D_2=20mA$) mode showed some difference (p<0.05). The difference of cadmium determination and recovery according to method of standard additions and standard calibration curve method in urine was not significant (p>0.05, $93.48{\pm}11.78%,\;94.83{\pm}22.00%$). Excretion of cadmium in 24-hour urine collection from normal person and variance analysis within measurement variation was not significant (p>0.05), but between interindividual was significant (0.05). Determination of cadmium content by two different methods of flame atomic absorption spectrophotometry and dithizone colorimetry showed that the results from the two methods can be described by a regression line with a good correlation (y=1.0153x-0.2927, x=Cd by D.C., y=Cd by A.A.S., $r=0.8651^*$, p<0.01).
