We used a series of Landsat images acquired from 1984 to 2001 to observe decadal changes of the research forest of Kangwon National University. Tree NDVI images of November in 1984, 1986 and 2001 were displayed in RGB color composite. This image enabled us to identify historical change of conifer types and their approximate ages. Conifers were classified into 'old conifer aged more than 25 years', 'young conifer aged 20-25 years' 'very young conifer aged less than 20 years', and recently deforested areas. The results coincide with in situ data very well. Archives of higher resolution images should be used to monitor the change of area for various tree types.

A 12-month-old, 3.0-kg, male, Scottish fold cat was referred to Irion animal hospital with dyspnea and cardiac murmur. In radiograph, right-sided cardiomegaly and pleural effusion were identified. In echocardiographic examination, abnormal stenotic region was identified in right ventricle and dilation of right atrium and concentric hypertrophy of interventricular septum and the free wall of right ventricle were also identified. In the stenotic region, abnormal muscular band was identified. The turbulent flow was identified in infundibular region of right ventricular outflow tract with color-Doppler examination and high velocity flow (4.0 m/s) was also identified in stenotic region. With these results, double-chambered right ventricle (DCRV) was diagnosed.

Acute idiopathic scrotal edema (AISE) is a self-limiting condition that is characterized by acute scrotal swelling and erythema. AISE is a very rare cause of acute scrotum, especially in neonates. We report a case of AISE in a 26-day-old infant who was admitted to the outpatient clinic with swelling and erythema of the penis and scrotum for a week. His vital signs were stable, and laboratory findings were non-specific. A diagnosis of AISE was made using scrotal ultrasonography with color Doppler. His symptoms resolved within four days after the onset of supportive treatment, and he was discharged from the hospital. In neonates with an acute scrotum, AISE should be considered to prevent unnecessary surgical exploration.

The wood veneers were clearly rainbow-colored with natural dyes. As shown through Korean-style jacket with stripes of multi-colors beyond traditional obang colors (red, blue, yellow, black and white colors), eco-friendly coloring methods representing Korean colors familiar from old times could be used nobly by coloring natural wood veneer being raw material of wood products. In terms of industrialization, the study to manifest korean color, substituting chemical stains such as dye and pigment, would be necessary. In order to realize this purpose, the study about economical dyeing materials and characteristics, that is, mordant, dyeing and drying techniques showing environment-friendly coloring and high coloration level ought to be followed. In addition to this, investigating discoloration transition by fading test for interior and exterior uses would have to be carried out.

The Effects of Dietary Supplemental Charcoal Extract (CE) were examined on performance of 19-week-old ISA Brown hens for 12weeks. Four hundred and fifty were randolmy assigned to 0, 0.025, 0.05, 0.075, 0.1% dietary CE, respectively with five replicates of 18 hens per pen. Basal diets contained 17.5% CP and 2,800 ME. Egg production egg weight, feed conversion(FC), and egg qualities were measured in every four weeks. Egg production and FC was slightly improved in 0.05% supplemental CE group compared to that of other treatments, but was not signhificant different. Average egg weight was significantly higher in 0.025% and 0.1% than other treatments(P<0.05). Total egg mass tended to be higher in 0.05% supplementation. Daily feed intake increased in 0.1% supplementation than the others, but was not statistically different. Eggshell breaking strength and Haugh unit were tended to be higher in 0.05% supplementation. There were no significant difference in eggshell thickness and yolk color of all treatments.

Supraclavicular lymph node (SCLN) flap is a common donor site for vascularized lymph node transfer for the treatment of lymphedema. Chyle leakage is a rare but serious complication after harvesting SCLN flap in the neck. We report a case of chyle leakage at the SCLN donor site and its successful management. A 52-year-old woman underwent SCLN transfer for treatment of lower extremity lymphedema. After starting a regular diet and wheelchair ambulation on the 3rd postoperative day, the amount of drainage at the donor site increased (8-62 mL/day) with the color becoming milky, which suggested a chyle leak. Despite starting a low-fat diet on the 4th postoperative day, the chyle leakage persisted (70 mL/day). The patient was started on fat-free diet on the 5th postoperative day. The amount of drainage started to decrease and the drain color became more clear within 24 hours. The drainage amount remained less than 10 mL/day from the 8th postoperative day, and we removed the drain on the 12th postoperative day. There was no seroma or other wound complications at follow-up 4 weeks after the operation. The current case demonstrates that a fat-free diet can be a first-line treatment for low output chyle leakage after a SCLN flap.

The objective of this study is to evaluate the effects of size and permittivity on the specific absorption rate(SAR) values of rat brains during microwave exposure at mobile phone frequency bands. A finite difference time domain (FDTD) technique with perfect matching layer(PML) absorbing boundaries is used for this evaluation process. A color coded digital image of the Sprague Dawley(SD) rat based on magnetic resonance imaging(MRI) is used in FDTD calculation with appropriate permittivity values corresponding to different tissues for 3, 4, 7, and 10 week old rats. This study is comprised of three major parts. First, the rat model structure is scaled uniformly, i.e., the rat size is increased without change in permittivity. The simulated SAR values are compared with other experimental and numerical results. Second, the effect of permittivity on SAR values is examined by simulating the microwave exposure on rat brains with various permittivity values for a fixed rat size. Finally, the SAR distributions in depth, and the brain-averaged SAR and brain 1 voxel peak SAR values are computed during the microwave exposure on a rat model structure when both size and permittivity have varied corresponding to different ages ranging from 3 to 10 weeks. At 900 MHz, the simulation results show that the brain-averaged SAR values decreased by about 54 % for size variation from the 3 week to the 10 week-old rat model, while the SAR values decreased only by about 16 % for permittivity variation. It is found that the brain averaged SAR values decreased by about 63 % when the variations in size and permittivity are taken together. At 1,800 MHz, the brain-averaged SAR value is decreased by 200 % for size variation, 9.7 % for permittivity variation, and 207 % for both size and permittivity variations.

This study was done to investigate the wearing experience, the taste and attitudes toward Korean Costume(Traditional and Saenghwal Hanbok). Data were collected by self-administered question from 307 elementary school children and 307 mother during 7, 2002. Conclusions are as follows : 1. Hanbok was worn mainly in the first birthday of children and 6∼7years old. But it was rarely worn in 4th∼6th grade of elementary school. Most of children had worn the Traditional Hanbok, about 30% had worn the Saenghwal Hanbok. 2. Childrens liked Saenghwal Hanbok more than Traditional Hanbok, girls liked Hanbok more than boys did. And 31.4% of boys disliked Hanbok, the main motives for dislike were concerned with the discomfort to move, the feel of cloth and becoming. Boys prefered the style of ´vest/ Jeokori/ Bajii´ in Traditional Hanbok, and ´half-sleeve Jeokori/ Baji´ in Saenghwal Hanbok. Girls prefered the style of ´Dangeui/ Chima´ in Traditional Hanbok, and ´One piece/ Jeokori´ in Saenghwal Hanbok. Childrens prefered analogous color scheme to contrasting color scheme. Boys prefered the blue groups, girls prefered the orange and red groups. 3. Childrens had more positive attitudes towards Saenghwal Hanbok than Traditional Hanbok. Mothers had positive attitudes towards both these types. And the attitudes toward Saenghwal Hanbok and Traditional Hanbok of childrens were more positive than mother´s. Therefore the following suggestions may be proposed for the development of Hanbok for children. 1. Hanbok is need to be designed considering activity, feeling and becomingness for teenagers. 2. Hanbok design must be kept seperated Traditional Hanbok and Saenghwal Hanbok. Traditional Hanbok is need to emphases tradition, Saenghwal Hanbok is need to apply a western style and have a practical use.

Hanboks have evolved throughout time; for example, the curved Barae has changed into a more modern and sophisticated straight one. The development of staining techniques has increased color selections with more luxurious designs. I suggested a design of Dolbok that considers functionality, practicality and economic feasibility through a comparison of past and present designs. I suggested a fusion Hanbok based on a traditional Dolbok for baby boys and girls. An abundance of cheap resources has decreased the tradition of hand down clothes; therefore, I created functional and economic methods to adjust a Hanbok for kids to wear a long time. First, I made it possible to adjust the length of a skirt by a slip stitch (or catch) stitch with a Seurandan (ornate lower band) and placed the button on shoulder part of the skirt for baby girls. The width of skirt is designed for a 4 year old instead of 1 year old to adjust the size and compensate for growing kids; however, the clothes still look stylish despite the overlapped area. Second, I made a baby boy's vest with a belt that follows traditional methods that were comfortable for width variation. Third, I made Geodeulji (sleeve-ends trimmed with wide bias) that enabled long or short sleeves. Geodeulji made with a variety of fabric colors will enhance the decorative effect. Fourth, I made the width of clothes adjustable by putting Korum (tie) ON Jeogori for baby boys and girls. There are many studies on Hanboks but few reports on modern Dolbok. I believe that designers should further study fusion Hanboks within framework of traditional Hanbok designs to increase comfort and appeal.

This study was performed to investigate the effects of laying productivity and egg quality according to providing germinated and fermented soybean (GFS) as feed additive. Among the strain, we selected Monascus purpureus KCCM 12002 so that inoculated in soybean and fermented for 48 h at $20^{\circ}C$. A total of two-hundred forty 70-wk-old Hy-Line Brown layers were divided into four groups (4 treatment${\times}$6 replication${\times}$10 birds each) and fed diets containing 0 (as control) (T1), 0.5% (T2), 1.0% (T3) or 2.0% GFS (T4) for 6 wk. The laying productivity, egg quality and blood property in the egg yolk were experimented. There were no significant differences in the laying productivity, relative liver and spleen weights, egg yolk color and eggshell strength among another groups. The eggshell color, eggshell thickness and haugh unit significantly increased in the GFS-supplemented group (p<0.05) compared to control. However, no significant differences were observed in the blood property after supplementation. The amount of lactic acid bacteria present during storage increased by providing of GFS (p<0.05) compare to control group. Our study results suggested that GFS can be used as a favorable feed additive and feedstuff for the productivity of high quality eggs and promoted relative industry.
