Teaching methods should focus on enabling the students to adopt an open mind towards new experiences and to be flexible to change. Moreover, their purpose lies in encouraging the students to build their ability to discern values so that they can make the right decisions when they are at a crossroad. However, traditional teaching methods were centered on textbooks and on the teachers. This type of teaching method needs to change so that the new teaching method will focus on the students themselves, taking levels of individual students into consideration to enable development of their creativity in line with the demands made during the 21st century, an era of information and globalization. Projected learning method is appropriate for the Physical Education (PE) classes where various activities aim to increase the level of cooperation among students and their investigative skills. Moreover, PE classes pay special attention to the practical aspect. Accordingly, this research makes recommendations for the class execution methods based on projected learning by improving the curriculum for the PE classes, and the effect of these methods are subject to verification.
The typeface of the Shhnch 'ongjon woodblocks is unsophisticated and old-fashioned while at the same time having a tidiness and strength that give it its special appeal. This is the typeface used in publishing novPls for sale to the common people during the latter half of the Choson Dynasty_ Their demands could not be satisfied with most currently available literature. which was intended to suit the tastes of the official class. As a result of a development to overcome the unbalanced use of space characteristic of letterforms that followed the geometric principles of early Hangul. the typeface followed the refined. feminine "hrushstroke" style of kungch 'e. establishing itself as a "rough" face displaying the characteristics of carved. woodblock printing in answer to the needs of the common p-eople who had the greatest need of Hangul during the time of its f1owering. The Shhnch 'ongjon face is characterized by thin horizontal strokes. thick vertical strokes. and the appearance of being condensed left to right. They possess simple yet varied form. With these characteristics the Shimch' ongjon typeface. if revived and compared to other typefaces. has a beauty of structure and composition and a unique. modern lmage with excellent readability. giving it great significance for modern r langul typography.r langul typography.
Jeotgal (salted seafood) has been one of major fermented foods in Korea for long time. Although there are many studies about Jeotgal in various aspects of food, its immunological importance on hosts has not been elucidated yet. In this study, we investigated if several bacteria isolated from Jeotgal may modulate the function of dendritic cells (DCs), powerful antigen-presenting cells equipped with special immunological capabilities. 4 Jeotgal bacteria were selected as representatives and used for experiments. To treat viable DCs, those bacteria were killed at $60^{\circ}C$ for 30 min. The viability of DCs treated with Jeotgal bacteria was verified and two isolates significantly induced high production of interleukin-12, a representative cell-mediated cytokine of DCs. Surface activation and maturation markers (MHC class II, CD40, CD86) of DCs were analyzed by flow cytometer. In addition, the treated DCs showed significantly high lymphocyte stimulatory capability compared to control DCs based on allogeneic mixed lymphocyte reactions. These observations suggest that Jeotgal isolates can function as immunostimulating bacteria in hosts, like Lactobacillus. Taken together, these experimental evidences may broaden the use of Jeotgal isolates in immunological fields in addition to as a fermented food.

Many inborn errors of metabolism can be completely cured with early detection and early treatment. This is why neonatal screening on inborn errors of metabolism is implemented worldwide. In 1991, the Ministry of Health & Social affairs adopted a nationwide service program for neonatal screening of phenylketonuria, galactosemia, maple syrup urine disease, homocystinuria, histidinemia and congenital hypothyroidism for newborns delivered from low class pregnant women registered in health centers. Government decreased the test items from six to two, PKU and congenital hypothyroidism to increase test numbers with same budget from 1995. 78 laboratories wanted to participate for neonatal screening test in 1999. Government decided to screen six items of PKU, congenital hypothyroidism, maple syrup urine disease, homocystinuria, galactosemia and congenital adrenal hyperplasia from 2006. In 2014, thirteen laboratories are participating. Inter laboratory quality control was started 6 times a year from 1994. In case a patient with an inherited metabolic disease is diagnosed by screening of government program, special milk is provided at government's expense. According to the government project, from 1997 to 2013, 7,080,569 newborns were screened. 144 PKU, 2.451 congenital hypothyroidism were detected. So incidence of PKU is 1/49,170 and congenital hypothyroidism is 1/2,888. The cost benefit of performing screening procedures coupled with treatment has been estimated to be as high as 1.77 times in PKU, 11.11 times in congenital hypothyroidism than cost without screening. By January 2007, many European countries had expanded of their newborn screening programs by inclusion of Tandem mass spectrometry. We are trying to increase the budget to test all newborns for Tandem mass spectrometry from 2016. We are considering four to five central laboratories which cover all newborns and are equipped with tandem mass spectrometer & enzyme immunoassay for TSH, 17OHP & enzyme colorimetric assay for galactose. And I hope to expand test including Wilson disease screening test and lysosomal storage diseases.

Objectives: This study aimed to evaluate the relationship between filter replacement and filter performance change in particulate filters used in the workplace. Methods: Three types of particulate respirator filters are mainly used in the workplaces. These were tested against the filter performance safety certification standard for dust masks established by the Ministry of Employment and Labor(MoEL). Used filters were collected to test their performance, such as filter pressure drop, efficiency, and quality factors. All these factors were evaluated by a filter tester. To compare filter performance between used and new ones, the same kinds of new filters were also tested together under the same procedures. Results: A total of 270 used filters were collected for testing. The main reasons to replace the filters were difficulty in breathing(46.2%), dirty/odor influx(19.7%), and a combination of factors(26.7%). The pressure drop for two special class groups was significantly different(new filters: $20.72{\pm}3.33mmH_2O$; used filters: $24.70{\pm}5.26mmH_2O$, p<0.0001). In the case of penetration, new filter groups indicated $0.0032{\pm}0.0040%$, while that of the used filters was $0.0596{\pm}0.1187%$. The quality factor for the used filters($0.34{\pm}0.09$) significantly decreased compared to the new filters($0.53{\pm}0.08$) (p<0.0001). Conclusions: Filter performance including pressure drop, penetration, and the quality factor was evaluated and compared between new and used filters in the workplace. The results showed that general filter performance deteriorated more for change of pressure drop, penetration and the quality factor.

The purpose of this study is to find out the influence of Home Economics learning on the recognition and attitude of middle school boy’s home life and to suggest the basic materials for the development of the Home Economics education through students’opinion of Home Economics. For this purpose, a survey was conducted in Cheong-ju area using questionaire. The subjects were 487 boys who studied Home Economics (HE group)and 480 boys who studied Technique (T group) in middle school. The statistics used for data analysis were t-test and x$^2$-test. The results of this study were as follows: 1. The recognition and attitude to home life on the general characteristics of home life; In urban area, the interests in bealth and the role of the consumers were higher than those of rural areas-on the bases of the standard of life, the middle class students had a higher interest in nutrition and food habits, the students whose father were engaged in special job had a higher interest in health and nutrition. 2. The difference of the recognition and attitude between HE & groups; In the field of food life, HE’s knowledge about the six nutrients and the basic food groups and attitude toward buying food were higher than T’s. In the field of family life and resources, HE and T accepted the importance of family life and the role of home as important, hoped to get psychological relax from home and to take the right sexual education. In the field of clothes life, HE and T had the general tendency to have their clothes in proper manner and to select their clothes for themselves, but HE took a higher interest in clothes mending and the role of clothes. 3. The opinions on Home Economics; HE answered that Home Economics was useful to them (more than 90% of HE) and that 57.1% of HE were interested in Home Economics. The order of interest among three fields were as follows: food life, clothes life, family life and resources. 71.9% of T hoped to take Home Economics course.

This paper is concerned with the dynamics of hyperelastic solids and structures. We seek for a smart control actuation that produces a desired (prescribed) displacement field in the presence of transient imposed forces. In the literature, this problem is denoted as displacement tracking, or also as shape morphing problem. One talks about shape control, when the displacements to be tracked do vanish. In the present paper, it is assumed that the control actuation is provided by imposed eigenstrains, e.g., by the electric field in piezoelectric actuators, or by thermal actuators, or via analogous physical effects, such as magneto-striction or pre-stress. Structures with a controlled eigenstrain-type actuation belong to the class of smart structures. The action of the eigenstrains can be conveniently characterized by actuation stresses. Our theoretical derivations are performed in the framework of the theory of small incremental dynamic deformations superimposed upon a statically pre-deformed configuration of a hyperelastic solid or structure. We particularly ask for a distribution of incremental actuation stresses, such that the incremental displacements follow exactly a prescribed trajectory field, despite the imposed incremental forces are present. An exact solution of this problem is presented under the assumption that the actuation stresses can be tailored freely and applied everywhere within the body. Extending a Neumann-type solution strategy, it is shown that the actuation stresses due to the distributed control eigenstrains must satisfy certain quasi-static equilibrium conditions, where auxiliary body-forces and auxiliary surface tractions are to be taken into account. The latter auxiliary loading can be directly computed from the imposed forces and from the desired displacement field to be tracked. Hence, despite the problem is a dynamic one, a straightforward computation of proper actuator distributions can be obtained in the framework of quasi-static equilibrium conditions. Necessary conditions for the functioning of this concept are presented. Particularly, it must be required that the intermediate configuration is infinitesimally superstable. Previous results of our group for the case of shape control and displacement tracking in linear elastic structures are included as special cases. The high potential of the solution is demonstrated via Finite Element computations for an irregularly shaped four-corner plate in a state of plain strain.

This study investigated a special class or Electronic Data Interchange(EDI) system. While it has been predicted that the use of EDI will have a significant impact on the competitive advantage of organization. very little is known about the successful construction of such system. A few studies done in this area have relied on anecdotal data on data based on a small number of case studies. The major objectives of the research are to identify the factors that facilitate the adoption and successful construction of an EDI system, and to evaluate the impact of the EDI system on competitive advantage of the organization. Based on the EDI literature. organizational performance is modeled to be affected by three independent variables: EDI system. communication. trust. The level of EDI system was used as control variable. The data used to test the model were collected in a mail survey from department store in Korea. The results indicate that organizational performance is affected by EDI system, communication. The paper concludes with a discussion of future directions for research in the area of test EDI models.

The purpose of this study is to female child Han-bok reform design for body growth. Nowadays there is common the western style daily life and special day instead of traditional style Han-bok in Korea. So the decrease in the use of Han-bok have being appeared. Specially, Children's Han-bok undesirable clothes for economic, environment, and resources because of their rapid growth and changing trend. Therefor, they do away with used Han-bok without next buying of school age. Children's parents and children are decision together purchase of children's Han-bok on-line for pleasure and economic reasons on pre-school or 1st year student for their tradition-education class. After 2000year, children's Han-bok pup-up on e-market because of the fashion focus on tradition and Korean wave for parody of Korean drama. Flowing the Research of 2010 Size Korea, the elementary school age child height growth 6cm per year, the sleeve length are 3cm growth. But Chi-ma(a pice of Han-bok) from e-market, has only 5cm margin on shoulder and no margin on Jegori(a pice of Han-bok) shoulder and sleeve, reason of that the children can't wear next year. Therefor this study is development female child Han-bok reform design for body growth, for extend to wear Han-bok on school age children and flow tradition custom of Cho-sun Dynasty's clothing custom for boost tradition conscious and reduce of cloth waste for environment.
This research was conducted to investigate the physicochemical characteristics of stream water at the four points in the northeastern part of Puk'ansan National Park from July, 1998 to November, 1999. The average pH of stream water was 6.65 and dissolved oxygen was $10.7mg/{\ell}$, which indicated that the quality could be categorized in the first class for the quality of river water quality standard. In addition, the water was soft water and average percentage of dissolved oxygen was 96.7%, which was almost saturated. The number of visitors resulted in the increase of dissolved ion, witch affected on electrical conductivity of the water. The relationships between those factors was significant at the 1% level in linear regression. The electrical conductivity and the amount of anion($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$)in downstream were higher than those in upstream.
