The paper is investigation of the secondary vegeation and succession at the forest fire area in Mt. Palgong. The survey was carried out from April, 1981 to Stempter, 1982. The floristic compositions were as follows: 50 families, 116 genera, 127 species, 15 varieties and 3 formae(145 kinds). Among them, the floristic composition of the pine floor vegetation of the unburned area was 43 families, 80 genera, 88 species, 10 varieties and 1 forma(99 kinds), and that of the secondary vegetatiion after forest fire was 46 families, 106 genera, 120 species, 14 varieties and 3 formae(137 kinds). Index of similarity between the burned and unburned area was 0.77. The biological type succeeded in $H-D_1-R_5$type, and the erect form(s) was prevailed. Carex humilis var. nana, Miscanthus sinensis var. purpurascens, and lespedeza cyrtobotrya were dominant species in the $ B_1; and; B_2$ area of the seventh year after forest fire. In the degree of succession, species diversity, and evenness index, DS, H, and e of the $B_1$ area were higher than those of the $B_2$ area. In the soil properties, it assumed that pH, total nitrogen, and available phosphores of the burned area were nearly recovered to those of the unburned area.

Even if we can recover the function of mastication, pronunciation and esthetic using the fixed or removable prosthesis in the loss of teeth or hard tissue in the oral cavity, we use several kinds of implants in order to solve the problem which can be occured when we can't install the denture because of excessive bone resolution or psychlogical affairs. At present Titanium implant plays a major role in this field and has osseointegrated. And the study on the modern material is going on, that result in developing and using the implant which is coated with HA, bone induced material. In this, I studied histologically the change of the bone tissue which is occured when three kinds of HA coated implants. Such as Integral, Sustain, Biovent implanted into mandible of dog and got a 8-weeks healing period. I got the conclusion as follows: 1. Most of the implant which is covered with serveral kinds of HA coating implant in bone after 8 weeks being implanted and has osseointegrated, partially converted into the connective tissue. 2. Biovent formed the connective tissue in the perforated area of inferior alveolar canal and has osseointegrated.

The objectives of this study were to investigate university students' knowledge of traditional dishes and seasonal festive foods, and to estimate the level of consumption in Korea. The result of the study indicated that their level of knowledge of the seasonal festive foods was very low on as average. The reason was that, because each family prepared only one or two festive dishes on seasonal festival days, these students had few opportunity of being acquainted with other kinds of festive foods. In case of traditional foods university students ate some traditional foods. However, they age other kinds of traditional foods such as Jun-Gol and San-Juk less than once a month because of the difficulty in cooking these foods everyday. Finally, the students showed their intention to eat more traditional foods and festive foods if they can find these types of foods easily. The findings of this study suggested that, in order to increase the consumption of our traditional foods, it is necessary to encourage the establishment of many traditional food stores and to provide an easy access to these stores. Furthermore, every effort should be made to develop various kinds of food materials and easy recipes which can be used at home.

This study examined the kinds, expression, techniques and arrangement of patterns for the traditional women's costume from 1995 to 2002 in North Korea. And the results were compared with South Korean. Conclusions are as follows : In the kinds of patterns the natural plant patterns were much more frequently used in North Korea. These tendency was same to South Korea. And the geometric patterns were more frequently used in South Korea. According to frequency in the expression of patterns, it was the realistic, geometric, stylized shape in North Korea. To the contrary it was the stylized, geometric, realistic shape in South Korea. In terms of decorative techniques, not only the traditional embroidery, gold leaf, multicolored stripes, but also modern collages, painting, beads, applique, flounce, ruffle were used in North Korea. Modern techniques were found comparatively a lot in North Korea, traditional techniques were found comparatively a lot in South Korea. In terms of arrangement of patterns, the modern arrangement was much more frequently used. And localized type of modern arrangement was found comparatively a lot in South and North Korea. Therefore traditional beauty was generally expressed by natural patterns, realistic shape and modern beauty was generally expressed by modern techniques and arrangement of patterns in North Korea.

This study was investigated to evaluate the physiological responses on T-shirts manufactured with selected functional materials by body parts which were selectioned on the distribution of sweating and temperature change. Seven healthy men in twenties were participated in a climate chamber of $27{\pm}0.5^{\circ}C$ and $50{\pm}1%RHC$. Three kinds of T-shirts named 'D1', 'D2' and 'Poly' were used as experimental clothings. Four kinds of functional materials of quick absorbing/drying were used in all section in 'D1', but two kinds of functional materials used partially in 'D2'. 'Poly' T-shirts used only polyester. In an experimental schedule of 90 minutes, which were consisted of 'Rest', twice of 'Exercise' and twice of 'Recovery' periods, the subjects walked on a treadmill with 60% of $VO_2max$. As a physiological responses, the microclimate temperature, surface temperature(skin, clothing) and sweat rate were measured. Temperature regulation was kept well in 'D1' rather than other T-shirts. The quick absorbing/drying T-shirts showed its performance well as the exercise goes on the second half. With these results in mind, 'D1' will be more effective for long hours exercise such as climbing rather than short hours exercise.

In this study, both kinds of materials, that is, leather and woolen fabrics, which have similar thickness, have been adopted. To determine proper length of ease, not only sleeve cap height but also sleeve width has been adjusted mainly based on 5cm length of the ease, which follows maximum sleeve cap height, and then different length of ease, for example, 4cm, 3cm, 2cm and 1cm of ease, have been made. As a result, eighteen kinds in total of sleeves have been made: In other words, each nine kinds of both leather and woolen fabrics have different ease lengths. In addition, each sleeve has been inspected visually and functionally. Following conclusion has been gotten based on outcome of the study: 1. Proper ease length for manufacture of leather garment is said to be 1∼2 cm. As a result, ease length with higher sleeve cap height shall be 1∼2cm, while the length with lower sleeve cap height shall be 1cm or less. 2. Wider sleeve width has better function. Considering relations with sleeve cap height, sleeve width shall exceed +4cm of bicep line. 3. to satisfy a variety of those conditions while manufacturing leather garment, sleeve cap height, which is used for the manufacture of full dress and street wear garment, To lessen the ease length, body A.H shall be relatively loose under the arms, or pad shall be supplemented on the shoulder, so that the difference had better be lessened to solve such problems.

In the modern construction industry, since numerous skyscrapers have been built, there have been sought for developing various kinds of methods for shortening a construction period. Therefore, many kinds of studies on some kinds of cold-weather concrete have been conducted actively for the purpose of a year-round construction. Accordingly, this research team once developed a double-layered bubble sheet as a surface-coated curing material for winter. And there have been raised some worries that some initial damages to frozen concrete caused by low temperature of reinforcing bars which are exposed out of the wall areas of a wall-type apartment during winter. Therefore, in this study, it is intended to find out clearly whether it is possible for concrete to be damaged initially or not by analyzing the temperature characteristics of the exposed reinforcing bars of the wall areas under the temperature conditions during winter.
