Purpose. This study of purpose was to to compare of Aerobic and Anaerobic Capacity between Sasang Constitutions and ACE Gene Polymorphism. Methods. 24 healthy males were participated in this experiment who were in their twenties and had no disease, then they were divided by ACE type and by Sasang constitutions with QSCC II. According to these group, the body compositon, Aerobic capacity including VO2max, Anaerobic Capacity were measured. Results. In this study, According to ACE type, ID type were 8, II were 8 and DD type were 8 persons. According to ACE type, there were significant difference among type, especially, II, ID type more than DD. II type is more higher than any type and DD type is lower in the ratio of Blood Lactic recovery. DD type was more excellent than other type in Anaerobic power. According to Sasang Constitutions, there were 8 SoYang, 5 Taeum, 11 Soeum and then no TaeYang constitution. In Aerobic capacity, Taeum constitution had significantly high means and Anaerobic threshold. In the ratio of Blood lactic recovery, Taeum constitution was excellent and SoYang had poor recovery capacity. SoYang had more excellent than other constitution significantly in Anaerobic capacity. Comparing ACE type with Sasang constitution, Soyang constitution included 4 ID types, Taeum inclued 2 II types and 2 ID types then Soeum included 6 DD types. Compared of Aerobic and Anaerobic capacity between Sasang constitutions and ACE type, Soyang constitutions were similar to ID type, Taeum similar to II type and ID type and then Soeum were DD type. Conclusions. This study had made it clear that there were similar feature between ACE type and Sasang constitutions. Also it's possible to predict the Aerobic capacity that may be foreseen by ACE type with Sasang questionnaire method but not Anaerobic capacity.

Knowing the mean free paths (MFPs) of thermal phonons is an essential step in performing heat transfer analysis for nanomaterials, and in determining the optimum design for tailoring the heat transfer characteristics of nanomaterials. In this study, we present a method that can be used to calculate accurately the phonon MFP spectra of nanostructures based on simple phonon kinetic theory. Here, the kinetic theory may be employed by extracting only the diffusive-transport part of the phonon spectrum (i.e., the MFPs are less than a thermal length). By considering phonon dispersion and polarization effects, the phonon MFP distributions of silicon at room temperature are calculated from phonon transport properties and the spectral MFP. Our results are validated by comparison with those of the first principle and MFP spectroscopy data.

In general, zona pellucida (ZP) of the blastocyst has to be removed first, then either isolated the inner cell mass (ICM) or ZP-removed whole blastocyst, which is then cultured on the feeder layer to induce ICM outgrowth for the generation of embryonic stem cells (ESC). However, it is unclear whether ICM isolation before seeding on feeder layer is beneficial or not because the interaction between ICM and trophoblasts may affect cellular growth and/or pluripotency during the culture on the feeder. In the present study, two ZP removal methods (mechanically by splitting with a 28-gauge needle versus chemically by the treatment of acid-Tyrode's solution) and two ICM isolation methods (ZP-free whole blastocyst seeding versus mechanical isolation of ICM) were evaluated for the efficient isolation and culture of putative parthenogenetic bovine ESC. The number of maintained outgrown colonies was counted in each experimental group. As the result, mechanical removal of ZP with a needle and followed by whole ZP-free blastocyst seeding on feeder cells tended to attach more on the feeder layer and resulted in more outgrown colonies with its simple and less time-costing benefits. Currently we are generating ESC lines in HanWoo cattle by using this method for initial outgrowth of the parthenogenetic bovine blastocysts.

According to Ayurveda, an individual can be classified into any one of the seven constitutional types (Prakriti) depending on the dominance of one, two, or three Doshas. A 'Dosha' is representative of fundamental mechanisms that are responsible for homeostasis, and thus, to health. In the recent years, there have been several efforts to see whether certain physiological, haematological or biochemical parameters have any relationship with the constitutional types or not. The objective of the present study was to see if the results of autonomic function tests vary according to Prakriti of an individual. We conducted this study in clinically healthy volunteers of both the gender belonging to the age group of 17 to 35 years after obtaining their written consent. The Prakriti of these volunteers was assessed on the basis of a validated questionnaire and also by traditional method of interviewing. After confirming that the primary Dosha ascertained by both these methods matched, 106 volunteers were grouped into three on the basis of primary Dosha and were subjected to various autonomic function tests such as cold pressor test, standing-to-lying ratio, Valsalva ratio and pupillary responses such as pupil cycle time and pupil size measurement in light and dark. The results suggest that, the autonomic function tests in the healthy individuals may correlate linearly with the primary Dosha expressed in an individual. In particular, people with Kapha as the most dominant Dosha showed a tendency to have either a higher parasympathetic activity or a lower sympathetic activity with respect to their cardiovascular reactivity in comparison to the individuals with Pitta or Vata as the most dominant Dosha.

Reactive sprays of two propellant combinations(GOx/kerosene and $GN_2O$/ethanol) were observed and compared with each other as a basic research of visualizing supercritical combustion. A shadowgraph imaging method was used to visualize the reactive sprays, and shadowgraph images were converted to density gradient magnitude images to analyse the structure of reactive sprays. The gas-liquid interface of GOx/kerosene spray showed rougher boundary and steeper density gradient near the injector face than the $N_2O$/ethanol at similar combustion chamber pressure. Spray core length was calculated from averaged density gradient magnitude images and it was revealed that spray core length of GOx/kerosene was shorter than that of $GN_2O$/ethanol, although momentum flux ratio of GOx/kerosene propellant combination was lower.

Nutrient intakes estimated using a 24-hr recall, a dirt record and a food frequency questionnaire(FFQ) were compared in a group of ninety-four elderly people(21 males, 73 females) in Cheongju, a city in Chung-Buk province. Mean intakes for energy, protein, Ca, p, Na, K thiamin and niacin obtained from the diet record were higher than those from the 24-hr recall. Mean intakes for energy, protein, Ca, P, Na, K thiamin, niacin and vitamin C from the FFQ were higher than those obtained from the 24-hr recall or the diet record. Correlation coefficients between the nutrient intake values from the 24-hr recall and those from the diet record ranged from 0.84 to 0.95 and were significantly correlated(p < 0.001). About 80% of the subjects in the lowest quintile by the 24-hr recall were also in the lowest two quintiles by the diet record. While the percentage fallen into the opposite category ranged from 0% to 15%. For most nutrients, at least 65% of the subjects when classified by the 24-hr recall fell into the same quintile when classified by the diet record, and the mean kappa value was 0.7. About 52% of the subjects in the lowest category by the 24-hr recall fell into the lowest two categories by FFQ. The mean percentage of the subjects in the lowest quintile by the diet record or in the lowest two quintiles by the FFQ was 51%. For most nutrients, at least 24% of each of the subjects when classified by both the 24-hr recall and the diet record fell into the same category when classified by the FFQ. The kappa values between the 24-hr recall or the diet recall and the FFQ were 0.17. These data indicate that in elderly subjects the 24-hr recall can provide very similar information to that obtained from the diet record but the FFQ can not provide good information if the right FFQ method is not used for only elderly subjects.

The objectives of this study is to analyze the curriculum based on the hypothesis of bodyguarding related department and to research the differences of the amongthree groups of public bodyguarding, private bodyguarding and bodyguarding professors with its significance in order to establish the development of direction in education curriculum for bodyguarding related departments at university level,For this purpose, this study categorized the sample group into three kind and surveyed them, Those are public bodyguarding members, private bodyguarding member, and the professors and 121 samples were selected in those three with the help of self-admistrated method, which is one of the sampling methods, First, among the current bodyguarding related theoretical disciplines significant differences among groups was presented by the evaluations on bodyguarding science, traffic safety management, fire extinguishing, secretary science, administration, psychology, sports education, sport physiology, jurisprudence and philosophy, which showed differences among groups through the multiple comparison, But there was no significant difference among the means of the groups concerned with the other curriculum, We could know that more curriculum is needed to facilitate the private bodyguarding in disciplines and system of the current theory in this study. For it is predicted the demand for the private bodyguarding will increase continuously in the future. for which we should prepare. Thus it is required to increase the theoretical curriculum of the private bodyguarding. That is. the models of curriculum like introduction to machinary guarding. introduction to communication. computer theory and so on are required to be established. In addition to that. it must be noticed that the current private bodyguarding is not guaranteed by the legitimate institution. But the private bodyguarding is related to the police service. thus the curriculum of jurisprudence and police science should be studied together.

The main purpose of this study was to develop, implement, and evaluate a weight control program for overweight elementary school children The results of our previous study in 1996 Identified overweight as one of several health problems among elementary school children in urban areas The research method utilized was a quasi experimental design using one group in a pre and post test comparison The sample consisted of 198 children from 3 elementary schools in Kyung-gi Province who were 20% over the ideal weight for their height Height and weight were measured and a BMI score was calculated at the beginning of the program and monthly thereafter. The program had three components: physical exercise, counseling of children, and health education of children, parents, and teachers. The program lasted from March, 1997 to November, 1997. The data were analyzed using an SAS PC statistical package. The results indicate that the overweight children in two elementary schools had statistically Significant changes in their BMI score after the program while those in one school id not. When the process notes were reviewed it was Identified that the school which showed little change averaged less physical exercise, and less parent and teacher participation in the program In conclusion, a school based weight control program is an effective way to manage and prevent obesity for overweight elementary school children It is suggested that a school wide exercise program may be better accepted by overweight children than a program specifically designed for overweight children only. One of the most important factors which determine the successful outcome of any health promotion project in school is the enthusiasm and cooperation of the principal and school health nurse.

In the environment where various and complicated threat signals exist, RWR (Radar Warning Receiver), which can warn pilot of the existence of threats, has long been a necessary electronic warfare (EW) system to improve survivability of aircraft. The angle of arrival (AOA) information, the most reliable sorting parameter in the RWR, is measured by means of four-quadrant amplitude comparison direction finding (DF) technique. Each of four antennas (usually spiral antenna) of DF unit covers one of four quadrant zones, with 90 degrees apart with nearby antenna. According to the location of antenna installed in helicopter, RWR is subject to signal loss and interference by helicopter body and structures including tail bumper, rotor blade, and so on, causing a difficulty of detecting hostile emitters. In this paper, the performance degradation caused by signal interference by tail rotor blades has been estimated by measuring amplitude video signals into which RWR converts RF signals in case a part of antenna is screened by real tail rotor blade in anechoic chamber. The results show that corruption of pulse amplitude (PA) is main cause of DF error. We have proposed two algorithms for resolving the interference by tail rotor blades as below: First, expand the AOA group range for pulse grouping at the first signal analysis phase. Second, merge each of pulse trains with the other, that signal parameter except PRI and AOA is similar, after the first signal analysis phase. The presented method makes it possible to use RWR by reducing interference caused by blade screening in case antenna is screened by tail rotor blades.
