The humans has tried to investigate the fundamental relationship of all phenomena through the eyes. In oriental medicine, inspection is a one way of diagnosing by observing outer shape of patients. Physiognomy is the study which infers characteristics, constitutions, predestinations of one man from his appearance. In other words, the study is about how inner spirit is expressed in the appearance and how we could understand the inner side from appearance. According to it, shapes, proportions and balances of human appearance also reflect the unrecognized characteristics of human. Esthetical beauty is product of seeing, it is considered with judgment of human just like beauty or ugliness, right or wrong, good and bad. In the east, they consider that the beauty is balance of nature, and that balance and harmony is important at human's face. For such a reason, the highest beauty has ideal as agreement ethical and aesthetic level through the harmony of ethical and physical beauty. And Physiognomy and inspection are the same as it.

When users use medical volume rendering applications, selecting specific region of volume data and observing the region by magnification is a common process.As the wood-grain artifact is arise from the magnified image, the jittered sampling technique has been used to remove the problem. However, the jittered sampling leads to some noise along the volume edge. In this research, we reveal the reason of the noise, and present a solution. To remove the wood-grain artifact without the noise, we propose the empty space jittering and the sampling alignment method. Using these methods, we can produce high quality volume rendering images without noticeable time consuming.

Tilt rotor aircraft was developed for satisfying VSTOL (vertical short take off and landing) capability and cruise performance. However the noise generated by tilt rotor system causes one of the most serious problems. In this paper, noise characteristics of tilt rotor system in hovering flight are predicted by using free wake method and Lowson's formula. The flow field of the tilt rotor is simulated by using time marching free wake method, and the free field acoustic pressure is calculated through Lowson's formula. The predicted results are compared with experimental data at various observing positions. In the near field, they show good agreement with experimental data regardless of rotating speed and collective pitch angles of 6, 8 and 10 degree, although there are some discrepancies between prediction and experiment in the far field and at the rotating axis in the near field. It seems that the reason of these discrepancies is difference of unsteady force fluctuation between experiment and calculation.

Nowadays, many countries have strived to promote prospective industries and occupations at the national level under the global circumstances such as green growth, job creation and so on. For this reason, the decision making method for qualifications foresight which will be available for the mentioned category-prospective industry and occupation- is required for it's feasibility. Pilot surveys on future workforce demand and promotion policies on service industries which are selected as a prospective industry or occupation by government parties were conducted through this research. Based on them, available qualifications-including not only national(skill) qualification but also private qualification- which can be created for prospective industries and occupations related to green growth and job creation were predicted. On the other hand, observing the change of service industry, occupation and qualification abroad, this research attempts to present the decision making method for verifying the decision' validity on qualification in Korean service industry and related occupation. Applying multicriteria decision making, a preference was examined for checking the validity of the created qualifications by prospective service industries and occupations in both sides-experts and laypeople. Based on it's result, the research was conducted regarding a validity of new qualifications in prospective industries and occupations.

This study has developed the sex education contents including new natural family plan, concept and principle by receiving the opinions and advices from professionals and professors on sex education, by amending and supplementing existing teaching materials on sex, and examining the books related with sex education contents that reflect the request of teachers and students, and the lack of sex education teaching materials which have been the reason that needs of school sex education has been highly recognized but not vitalized. The developed sex education contents are 8 areas such as knowing my body right, caring my body, observing the ability of being pregnant, marriage, sexual intercourse, process of pregnancy, miscarriage, and sexual violence, 30 lower areas, and 105 detailed contents in their composition, and here are the results of analyses of the degree of request of nurse teachers and the students on them. The teachers showed highest request in the area of sexual violence(M =4.67), the next was my body care(M=4.44), knowing my body right(M =4.38), process of pregnancy(M=4.13), marriage(M=4.11) and sexual intercoursen (M=3.98), ways of judging the ability of being pregnant(M=3.88), and miscarriage(M=3.72) showed comparative higher request than normal. Not like the teachers, the students showed that they requested Marriage area as the highest need(M=3.04) and next was sexual violence(M=3.02), caring my body(M=3.00) to have been higher than normal. Process of pregnancy(M=2.99), Sexual intercourse(M=2.81), miscarriage(M = 2.77), observation of the ability of being pregnant(M=2.74), and knowing my body right(M=2.70) have been the requests lower than normal. This study showed that sexual violence, marriage, caring my body, were the items most requested by both the leacgers and students and in elementary school the development of sex education teaching materials on natural family plan suitable to the level of development of the children has been requested as it has had no inclusion of the concept of natural family plan, and the students in elementary school are concerned on indirect sexual contents related with physical health like regular exercise rather than direct sexual education contents including sexual intercourse. All these show that they are still so naive on sex. The sense of the teachers on sex has been connected with the level of achievement of sex education of the children as it has been the important cause of deciding the contents of sex education. Therefore the materials developed onesidedly by leaders without reflecting the needs or the preference of the students might be worries of bringing shameful. low quality and negative opinions on sex, and on the other hand the children might lose the concerns and interest on sex education, So the materials should be developed to have the contents of sex education coinciding with the request of the children.

Numerical prediction capability has been improved over the decades, but progress of prediction for high-impact weather (HIW) was unsatisfactory. One reason of low predictability for HIW is lack of observation data. The National Institute of Meteorological Research (NIMR) has been performed observation program for improvement of predictability, and reduction in social and economical cost for HIW. As part of this observation program, summer intensive observation program (ProbeX-2009) was performed at the observation-gap areas from 25 August to 6 September 2009. Sounding observations using radiosonde were conducted in the Gisang2000 research vessel (R/V) from the Korea Meteorological Administration (KMA) over the West Sea and the Eardo R/V from the Korea Ocean Research and Development Institute (KORDI) over the South Sea. Observation System Experiment (OSE) is carried out to examine the effect of ProbeX-2009 data. OSEs using Korea Local Analysis and Prediction System (KLAPS) and Weather Research and Forecasting (WRF) Model are conducted to investigate the predictability for a short time forecast. And, OSEs using WRF/3DVAR system and WRF forecast model are conducted to study the predictability for an extended time. Control experiment (K_CTL and CNTL) used only GTS observation and experiment (K_EXP and SWEXP) used ProbeX-2009 data from two system are performed. ETS for 3hr accumulated rainfall simulated by KLAPS-WRF shows that K_EXP is higher than K_CTL. Also, ETS for 12hr accumulated rainfall of SWEXP from 3DVAR-WRF is higher than CNTL. The results indicate that observation over the ocean has positive impact on HIW prediction.

Temperal and spacial analysis for catches have been drawing up a catch distribution chart and analysing catches and CPUE(Catch Per Unit Effort) using catch data with purpose of obtaining basic data to establish a selective method of effective fishing the tuna purse seine fishing ground.The temperature profile section and catch was surveyed to analyse the effect of catch in relation to the fishing ground environment.The results are as follows ;1. As for the catch variation between 1983 and 1984, the catch mainly took place on150^{\circ}E$, and after that it moved eastward enlarging the range of catch. In the monthly catch variation between January and February, the catches mainly happened on 135$^{\circ}$~ 150$^{\circ}$E, and then moved to the gradually westward. However, from July it moved to the South and from October Southeast.2. As to the eatch ratio for the school associated with the drifted object, the pelagic migrating school and the school associated with the biological objects, the catch ratio for the school associated with the drift objects was the highest. The catch ratio for the school associated with the drifted object was high in June, July and November whiles between January and March for the pelagic migrating school.3. SST(Sea Surface Temperature) was around 28~29^C$ on the observing line of 137^{\circ}E$ and the catches took place in the north equatorial counter-current situated on around $5^{\circ}~6^{\circ}N$. SST in the northern summer was 1^C$higher than winter and it was about 29~30^C$. The catch happened with the center of north equatorial counter-current. The reason why the catch mainly took place on the north equatorial counter-current is that main catch of tuna purse seine was the school associated with drift objects. It is thought that the fishing grounds are made in waters that have many drift objects like drift logs from the coast.

"Hon-Chon-Jeon-Do" is a woodcut star map with the size of $79.4cm{\times}127.5cm$, and was widely disseminated as it was made into a set with Kim, Jung Ho's "Yeoji-Jeon-Do". This study confirmed that Yixiang kaocheng xubian ("의상고성속편") star catalogue was used as a source to produce the star map, and the stereographic projection was applied with the projection center being the mid-point (Q) between the celestial and ecliptic north poles. The 'mid-circle' around the Q is arisen between the equator and the ecliptic, and on this circle, the hour angle and the ecliptic longitude of a star can be marked using the same scale. This means that the hour of the day and the season of the year can be read on the same dial of the mid-circle, and the application of this character in the practical use was the key point of the star map production. By observing either transits or positions of the 28 xiu (宿), it is easy to find the corresponding season and time by simply reading the dial on the mid-circle. This is just the function of a portable almanac and thus by disseminating it widely, the convenience of the people would have been promoted. For this reason, it can be stated that "Hon-Chon-Jeon-Do" was a practical astronomical tool which was produced by the western astronomical projection method and was used to find time and season. Choi, Han Ki and Kim, Jung Ho are strong candidates for the makers of this star map. The time of production is estimated to be 1848 ~ 1857, and "Hon-Chon-Jeon-Do" could be regarded as a good contributor to popularization of astronomy in the late Joseon Dynasty.

The intelligence is the capacity to recognize the things and implies the meaning of abstract thought, learning and adaptability to the circumstance. Recently, as the promotion of learning ablility and memory attracts many people's attention, many studies of this have been accomplished but the pharmacological methods could not promote the intelligence and memory. In oriental medical theory, the human body is composed of four elements - essence, energy, sprit, blood and among these elements, sprit is considered as the concept of vital energy and mind. Especially, from the Jang-Fu physiological point of view, the memory is closly related with the heart and kidney In oriental medicine, some experiments on animal and literature studies on the subject of memory promotion have done. But because of difference in memory mechanism between man and animal, it is not in reason to apply the result of experiment on animal to human. Therefore I have methodological study of memory promotion to set up the concept of oriental medicine and experimental theory about this and can obtain such conclusion. 1. The oriental medical therapy for memory promotion is following. nourishing the heart and blood, regulating the function of spleen, relieving the mental stress, reinforcing the heart and kidney, invigorating and enriching the blood. 2. The insufficient intelligence in a child is considered to not be full and in an old man, it is considered to decline by degrees. 3. It is needed to molecular biological study of neurotransmitter after the using of oriental medical therapy. 4. It is possible to study using the genetic mutation or observing the collateral of brain nerve cell.

Health effects associated with metal working fluid (MWF) exposures include dermatitis, respiratory disease, hypersensitive pneumonitis, and asthma. Frequently, occupational exposures to MWFs are controlled by ventilating an enclosure with an air cleaning unit that includes a fan preceded by various kinds of filtration. There are several kinds of air cleaning units used in machining centers. But the associated troubles have hindered from efficiently using these devices. The main problem is the relatively short period of filter replacement. The reason is that the air cleaning units usually do not have the de-oiling systems, thus leading the earlier clogging of filters and reducing the flow rate of hood. Thus, the first stage of study was conducted to overcome this problem by developing the new oil mist collector equipped with the easy de-oiling system. The principle of de-oiling is that the centrifugal force generated by spinning the drum covered by filter fabric separates oils from the filter fabric. It would be very similar to the spin-dry laundry. By adopting this de-oiling technique, the problems associated with the conventional oil mist collectors could be solved. Several tests/analyses were performed to make the lab-scale oil mist collector. The collection efficiencies and the de-oiling efficiencies of commercially available filter fabrics were tested. Subsequently, the endurance test were conducted by observing SEM photos of filter fabrics and measuring tensile strength/expansion coefficient after spinning the filter drum for 20 minutes at the different rotation speeds. By doing these experiments, the most appropriate filter fabric and rotation speed/duration were selected. Finally, the new oil mist collector was designed. In the near future, this device must be tested in the real machining center.
