본 연구는 다양한 디지털 기기에서 리스트 형태의 정보 디스플레이에 일반적으로 적용되는 랩어라운드 (Wraparound)의 유용성에 대해 조사하였다. 랩어라운드는 리스트의 첫 항목에서 커서를 위로 이동시키면 마지막 항목으로, 마지막 항목에서 커서를 아래로 이동시키면 첫 항목으로 커서가 점프하는 것을 말한다. 본 연구에서는 랩어라운드의 유용성을 검증하기 위해 리스트의 종류와 길이, 그리고 랩어라운드 기능 유무를 달리하여 두 번에 걸친 실험을 수행하였다. 실험 결과, 랩어라운드의 효과는 리스트의 종류와 길이에 따라 그 유용성이 달랐다. 긴 리스트에서는 랩어라운드가 있는 경우 커서의 이동횟수는 줄여주나 이동속도는 다소 느리게 만드는 효과가 있었다. 랩어라운드가 있음으로 인해 느려진 커서의 이동속도는 랩어라운드의 사용여부에 대한 인지판단 시간으로 인한 것으로 보였다. 리스트의 길이가 충분히 긴 경우, 느려진 이동속도로 인한 시간만큼을 랩어라운드로 인해 줄어드는 커서 이동횟수 만큼의 감소시간이 상쇄시킴으로써 전체적인 완료시간까지 감소시키는 효과를 가져왔다. 또한 실험참여자들은 리스트의 길이가 더 긴 경우에 랩어라운드가 더 필요하다고 생각하였다.

1. This study is to veri(y the characteristics of gauze fabrics focused on the them found at Sukga Pagoda. The remains researched are those of the Unified Shilla Dynasty around 8∼10 century. The found textile remains seem to be used as rugs or to be used for filling in spaces, wrapping silver reliquaries, equipments preserving relics of the Buddha, a gold-plated outermost reliquary, and so on. Since other remains found inside the Sukga Pagoda are national treasures, the textile remains can be considered as the fabrics of the highest quality. 2. Seven gauze fabrics, four non-designed gauzes and three designed gauzes, are found. They are all four-end complex gauze, weaved with the complex gauze technique. Two designed gauzes out of three designed gauzes are weaved in pattern by the clamp-resist dyeing technique and one is weaved in pattern by giving some changes in weaving. 3. In addition to the characteristics peculiar to gauze fabrics, such as thinness, fineness, and sparseness, another characteristic is found. That is, the difference in thickness between wefts and warps is over two times on the average in all of the seven gauze fabrics. Some of the gauze fabrics look like laces because of the huge difference in their thickness. 4. This research verified that with their transparency, are such materials that their beauty can easily be realized without adding various colors or patterns on the fabric by painting, embroidery, stitching old foil, or compound weaving technique.

Reduction of yam hairiness by nozzles in ring spinning and winding is a new approach. Simulation of the airflow pattern inside the nozzles provides useful information about actual mechanism of hairiness reduction. The swirling air current inside the nozzles is capable of wrapping the protruding hairs around the yam body, thereby reducing yam hairiness. Since production rate of winding is very high and the process itself increases yarn hairiness any method to reduce the hairiness of yarns at this stage is a novel approach. A CFD (computational fluid dynamics) model has been developed to simulate the airflow pattern inside the nozzles using Fluent 6.1 software. In this study, both S- and Z-type nozzles having an axial angle of 500 and diameter of 2.2 mm were used for simulation studies. To create a swirling effect, four air holes of 0.4 mm diameter are made tangential to the inner walls of the nozzles. S- and Z-twisted yams of 30 tex were spun with and without nozzles and were tested for hairiness, tensile and evenness properties. The total number of hairs equal to or exceeding 3 mm (i.e. the S3 values) for yam spun with nozzle is nearly 49-51 % less than that of ring yams in case of nozzle-ring spinning, and 15 % less in case of nozzle-winding, while both the yarn types show little difference in evenness and tensile properties. Upward airflow gives best results in terms of hairiness reduction for nozzle-ring and nozzle wound yams compared to ring yarns. Yarn passing through the centre of the nozzle shows maximum reduction in S3 values.

Many varieties in folk costumes have inspired fashion designs for a long time. Each country, with a unique style of its own reflects their own traditions, beliefs, customs and morals into their traditional costumes. The traditional methods of creating different ways of drapery methods by using only a rectangular piece of cloth have been passed down from generation to generation and it is still used today. This way of styling has been developed mainly in the Middle East, Asia and Africa and the modifiable ways of creating drapery wearing methods are as follows. The first modifiable styling method is changing the purpose of wearing costumes according to the needs and the wants of the person who wears it. The second method is exposing the knots on the surface of the garments and by doing this, there was no visible difference on the aesthetic formation and it did not alternate for a long time. This means that simple knot shapes have been used to tie edges of rectangular fabrics. The third method is a wrapping type of modifiable styling method, which has been used most commonly in folk costumes because there are lots of ways to wrap a rectangular cloth around the body. The fourth way is the fixed type of modifiable styling method and this method can only be noticed only in the Moroccan Izar using fibulas and belts to alter the shape of the Izar. The fifth method is the composite type of modifiable styling method. This method starts by cutting out cylindrical shapes of fabrics and then wraps or twists it to fit the body. The most significant character of modifiable styling methods in folk costumes is to use rectangular cloths, which varies only in ratio of length, width and sizes. Therefore, this study suggests that rectangular cloths can create enormous amounts of fashion styling which can be easily adapted and created in everyday fashion life.

We have performed eight, single transplantations of right lung in dogs from September, 1988 to March 1989 at the Thoracic & Cardiovascular Surgical department, Yonsei University, College of Medicine, Seoul, Korea. We wrapped bronchial anastomosis site with great omentum and used cyclosporin in preoperative and postoperative periods in seven cases except one. The one without wrapping the bronchial anastomotic site with omentum and using cyclosporin died due to bronchial anastomotic site rupture in postoperative fourth day. If there is no reason to choose one side over the other, we would generally choose to do left-sided transplant as this is technically somewhat easier because of the long length of recipient bronchus and the ease of clamping the left atrium proximal to the pulmonary veins. The right atrium limits the amount of left atrium that can have incorporated into the clamp proximal to the pulmonary veins on the right side. But we had chosen to do right-sided transplant of lung because we must take variable technical experiences on right sided lung transplant in dogs. We have to anastomose one of pulmonary vein and left atrial wall on right-sided transplant easily only with double ligation of one pulmonary vein because right atrium limited the clamp of left atrium proximal to pulmonary veins with decreased venous return and cardiac output in some dogs. All seven dogs with right-sided lung transplant had survived more than one day with good condition except one. The one dog have to be sacrificed to evaluate the difference between the gas analysis in pulmonary venous and arterial blood in post-operative eight hours. We found hemorrhagic pulmonary edematous changes of contralateral left lung in this dog. And also all dogs have to be sacrificed for the evaluation of surgical problems, anytime in post-operative periods without any cardiopulmonary resuscitative efforts when the general condition would be worse progressively. We found no any surgical technical errors in seven dogs except one with thrombi in suture site of left atrium. There were hemorrhagic pulmonary edematous changes of transplanted right lung in one, of contralateral left lung in one, of contralateral left lung with double ligation of its pulmonary artery in one, thrombi around left atrial sutures sites in one, multiple air leakage in one bronchial rupture in one due to rejection or infection. There were accidental extubation and delayed intubation in one and unknown cause of death in one.

In this study, general bacterial counts and coliform counts, which are hygienic indicator microorganisms, were tested for candy, chocolate, and jelly which are easily available and enjoyed around. After dropping each sample on the desk, indoors, and outdoors, it is immediately collected, or washed and collected to confirm the myth of the 3-second rule. Immediately after removing the wrapping paper, each sample was dropped on the desk, indoors, and outdoors, and after 3 seconds from the moment of contact with the surface, and then collected in a sample bag using sterilized sanitary gloves. After the same operation, each sample was rinsed for 5 seconds using sterilized sanitary gloves and sterilized distilled water, and then collected in a sample bag. The number of bacteria detected in non-washing candies was 41 CFU/g at outdoor and the number of bacteria detected in non-washing chocolate was 76 CFU/g at outdoor. The number of bacteria detected in non-washing jellies was 79 CFU/g at outdoor. Coliform group was not detected in all samples. This showed good results at the level of m = 10,000 or less, which is an allowable value suggested in the Food Code. Also, effect of washing on contaminated food was confirmed. This result is remarkably low compared with the microorganism specimens shown in Food Code, and it is confirmed that contamination occurs but not high value. Therefore, the myth of the 3-second rule is true compared to the figures based on Food Code. However, it showed the characteristics of bacteria that could survive and cross-contaminate on dry food surfaces and emphasized the importance of hygiene through food contact to unsanitary surfaces to minimize the risk of food poisoning.
