We designed high dose rate Ir-192 source which was prepared for substitute the Co-60 source in Ralstron unit (Simatsu, Japan) which is supplied for cervical cancer treatment. The source dimension is 1.5 mm in a diameter and 1.5mm thickness of cylinder and encapsulated with 3 mm diameter of stainless steel(SUS316L) to substituted for the Co-60 source size. The Ir-192 source was prepared the dose model for tissue dose computation through the experimental determination of apparent activity and applied the empirical tissue correction factors extended to 20cm distance. The tissue dose model was applied the 4.69 R/cm-mCi-hr gamma constant and the ratio of energy absorption coefficient of water to that of air showed 1.112 include filteration of the self-absorptions. In this experiments, we prepared the dose computation software to clinical usefulness.

The Earth's total magnetic field was extracted from on board TAM (Three Axis Magnetometer) observations of KOMPSAT-1 satellite between June 19th and 21st, 2000. In the pre-processing, the TAM's telemetry data were transformed from ECI (Earth Centered Inertial frame) to ECEF (Earth Centered Earth Fixed frame) and then to spherical coordination, and self-induced magnetic field by satellite bus itself were removed by using an on-orbit magnetometer data correction method. The 2-D wavenumber correlation filtering and quadrant-swapping method were applied to the pre-processed data in order to eliminate dynamic components and track-line noise, respectively. Then, the spherical harmonic coefficients are calculated from KOMPSAT-1 data. To test the validity of the TAM's geomagnetic field, Danish/NASA/French ${\phi}$rsted satellite's magnetic model and IGRF2000 model were used for statistical comparison. The correlation coefficient between ${\phi}$rsted and TAM is 0.97 and IGRF and TAM is 0.96. It was found that the data from on board magnetometer observations for attitude control of Earth-observing satellites can be used to determinate the Earth's total magnetic field and that they can be efficiently used to upgrade the global geomagnetic field coefficients, such as IGRF by providing new information at various altitudes with better temporal and spatial coverage.

The purpose of this study was to investigate the elementary school teacher's status and recognition of nutrition education (NE) in Incheon. A cross-sectional study was carried out using a self-administered questionnaire and subjects were 147 elementary school teachers. The results are as follows. Only 9.5% of the teachers had training in NE and 71.4% of the teachers with training increased concern about NE after training. As for experience of NE, 61.6% of the teachers experienced NE and more than half of them gave NE less than twice per month. There was a significant difference in reason for not giving NE between subgroups by teaching career; 57.7% of the teachers with career more than 10 years did not give NE due to too much other work. As for existence of nutrition educator in school, 48.9% of the teachers recognized its existence and 91.3% of them answered that dietitians have done NE. For correction of unbalanced diet, good table manner, and nutrition and growth, 97.9% of the teachers answered that NE is necessary in elementary school. As for proper time to start NE, 57.5% of the teachers answered kindergarten and 39,7% answered lower grade of elementary school. As for effective type for NE, 47.3% of the teachers answered NE as a part of other subject and 28.1 % answered NE as a separate subject. Also 69.8% of the teachers answered dietitian as suitable person for NE. As for newly establishing a NE subject, 37.9% of the teachers disagreed and as for most effective method for NE, 73.3% answered NE linked with school lunch program. Most of teachers recognized elementary school students' eating habit problem severe and change of their eating habit such as various food choice, no plate waste and good table manner after school lunch program. Therefore, it should be nationally supported that a standardized NE program is developed and coordinated among teachers, school lunch dietitian as NE specialist, family and community for elementary students' health and well-being.

This study is carried out to develope parent education methodology by analysing "${\acute{E}}cole$ des Parents" of France. To study this subject we approach by following three methodes. Firstly, we examined bibliographes to find out motivation of initiative caused from hystological and sociological circumstance. Secondly, to analyse chronological developement and modification of "${\acute{E}}cole$ des Parents" we interviewed with three periods of persons : founder, developer and actually working animators. In addition, we riviewed three hundred eighty volumes of $\underline{{\acute{E}}cole\;des\;Parents}$, from first jurnals to october, 1993. Thirdly, this study were approached by participant observation in actual activities, and by analyse statstical records and subject of articals. In results, we noticed following caractors working in french parent education system. All the regional "${\acute{E}}cole$ des Parents" are alined with "$F{\acute{E}}d{\acute{E}}ration$ Nationale des ${\acute{E}}cole$ des Parents et des ${\acute{E}}ducateurs$"(F.N.E.PE.) in educational polish but activities and methodes of education are independant with F.N.E.P.E., and in most different regional "${\acute{E}}cole$ des Parents" focussed the educational programes to the middle class families in economic point of view. these programes adjust very rapidly systematicaly to social requirment due to successed intensive research. Mordern programs tend to contain all members of family in stead of targeting only maternal members. Methodes of education by lectures and speechs only to deliver information also replaced by discussion, forum and groop animation to induce self-correction. We propose that the systems of FNEPE can be ideal models to solve many actual problems facing in Korean parent education systemes.

Word segmentation errors occurring in text preprocessing often insert incorrect words into recognition vocabulary and cause poor language models for Korean large vocabulary continuous speech recognition. We propose an automatic word segmentation algorithm using Markov chains and syllable-based n-gram language models in order to correct word segmentation error in teat corpora. We assume that a sentence is generated from a Markov chain. Spaces and non-space characters are generated on self-transitions and other transitions of the Markov chain, respectively Then word segmentation of the sentence is obtained by finding the maximum likelihood path using syllable n-gram scores. In experimental results, the algorithm showed 91.58% word accuracy and 96.69% syllable accuracy for word segmentation of 254 sentence newspaper columns without any spaces. The algorithm improved the word accuracy from 91.00% to 96.27% for word segmentation correction at line breaks and yielded the decomposition accuracy of 96.22% for compound-noun decomposition.

Capital punishment is a system which is not finished simply as one of interim penalty but does away with one person's existence eternally. It is not only opposite to the existential humanism but also contrary to social welfare's goal like social integration. Therefore, this study tries to find out the issues related to capital punishment and further tries to draw out the rightness of capital punishment abolition by critically reviewing the capital punishment system on the basis of the value and philosophy of correctional welfare. In brief, capital punishment is possible only when we negate the inviolable fundamental right which is called life right, and deny the human life existence which surpasses space and time. As long as we can not deny the macroscopic viewpoint to search out the basis of human behavior in the social system which is called culture and society, capital punishment system is contrary to the philosophy of welfare that total society is responsible for guiding members of society to pursue self realization on the basis of value like social solidarity and human dignity. Also, it is against the objective of correctional welfare to head toward special prevention by positive correction and rehabilitation. Capital punishment system ought to be abolished properly.

Progressive facial hemiatrophy, also known as Parry-Romberg syndrome, is a progressive and self-limited deformation of the subcutaneous tissue volume on one side of the face that creates craniofacial asymmetry. We present the case of a patient with a five-year history of progressive right facial hemiatrophy, who underwent facial volumetric restoration using cell-assisted lipotransfer (CAL), which consists of an autologous fat graft enriched with adipose-derived stem cells (ASCs) extracted from the same patient. ASCs have the capacity to differentiate into adipocytes. They also promote angiogenesis, release angiogenic growth factors, and some can survive as stem cells. The use of autologous fat as a filler in soft tissue atrophy has been satisfactory in patients with mild and moderate Parry-Romberg syndrome. Currently, CAL has showed promising results in the long term by decreasing the rate of fat reabsorption. The permanence and stability of the graft in all the injected areas has showed that autologous fat grafts enriched with stem cells could be a promising technique for the correction of defects caused by this syndrome.

Background Many people have an interest in the correction of facial scars or deformities caused by trauma. The increasing ability to correct such flaws has been one of the reasons for the increase in the popularity of facial plastic surgery. In addition to its roles in communication, breathing, eating, olfaction and vision, the appearance of the face also plays an important role in human interactions, including during social activities. However, studies on the importance of the functional role of facial appearance. As a function of the face are scare. Therefore, in the present study, we evaluated the importance of the functions of the face in Korea. Methods We conducted an online panel survey of 300 participants (age range, 20-70 years). Each respondent was administered the demographic data form, Facial Function Assessment Scale, Rosenberg Self-Esteem Scale, and standard gamble questionnaires. Results In the evaluation on the importance of facial functions, a normal appearance was considered as important as communication, breathing, speech, and vision. Of the 300 participants, 85% stated that a normal appearance is important in social activities. Conclusions The results of this survey involving a cross-section of the Korean population indicated that a normal appearance was considered one of the principal facial functions. A normal appearance was considered more important than the functions of olfaction and expression. Moreover, a normal appearance was determined to be an important facial function for leading a normal life in Korea.

Today, people are obsessed with fashion, makeup, hair care, weight control, and plastic surgery. In order to be satisfied with their appearance and attract attention, they invest so much time and money. The core values of many people are influenced heavily by materialism and appearance. Belly dancing is effective not only in just weight loss, but it also improves the health and corrects body postures like pelvis correction, and it also gives the dancers the pleasure of dancing to exotic music. A growing number of women in their 40s or older and senior citizens have become maniacs of belly dancing. The studies suggest that the participation in belly dancing helps increase life satisfaction and self-respect of the middle aged who often suffer from depression. Belly dancing has a strong effect in the life style of the middle-aged women. The costume and accessories necessary for belly dancing class help the participants) focus on the dance. These costumes and accessories reflect the desire of the wearer to be recognized in society. It is well shown in belly dancing that "fashion and beauty related services and products are used as an indicator to tell social status and position of the wearer as external elements like clothes, accessories, and physical appearance and have a highly important effect on interactions among people in society as a means of expressing oneself". In this respect, this study aims to examine middle-aged women's involvement in fashion and beauty depending on their participation in belly dancing.

A small UAVs(Unmaned Aerial Vehicles) have limited by the payload capacity which requires miniaturization of a navigation system. In this paper, the performance of the lightweight and small sized AHRS(Attitude Heading Reference System), which is self-developed, is evaluated at low acceleration environment. The designed AHRS adopts the commercial low-cost MEMS sensors. A quaternion-based attitude calculation method, which eliminates singularity with relatively simple algebra, is used. In an attitude correction algorithm, the Kalman filter is used with accelerometers and magnetometers combined. The fabricated AHRS is also evaluated with reference to a COTS(Commercial Off-The-Shelf) AHRS which reports a number of successful applications to a small UAVs. The test results show that the measurements from the fabricated AHRS provide proper attitude output data with acceptable amount of differences(horizontal axis 0.5$^{\circ}$, vertical axis 1.5$^{\circ}$) in test environment.
