이산화염소 훈증 처리는 저곡해충에 대한 방제 가능성을 가지고 있다. 특히 체내로 독성 가스의 침투력을 높이기 위해 기문의 개방화를 유도하면 이 훈증 가스 처리 효과를 증가시킬 수 있다. 이 가설을 증명하기 위해 본 연구는 이산화염소 훈증 처리에 감수성을 보이는 화랑곡나방(Plodia interpunctella)을 대상으로 기문 개방 활동을 분석하였다. 화랑곡나방 유충의 기문은 모두 9쌍으로 앞가슴에 1쌍 그리고 복부에 8쌍을 각각 지니고 있다. 이들은 몸 내부에 가로 및 세로기관지와 연결된 구조를 지녔다. 기문 개방 유무는 염색액 침투 방법으로 판정하였으며 이를 토대로 분석한 결과 주변 온도 증가에 따라 기문 개방화는 약 60% 까지 증가하였다. 특히 이산화탄소에 노출되면 기문개방화는 약 95%까지 증가하였다. 반면에 이산화염소에 노출되면 화랑곡나방 유충의 기문은 대부분 닫혀 기문개방율이 약 25%로 줄었다. 이산화염소 처리에 이산화탄소를 추가한 결과 기문개방율은 이산화탄소 단독 처리만큼 크게 증가하였다. 이를 토대로 두 혼합 가스를 처리하여 살충효과를 분석한 결과 이산화염소 단독 처리에 비해 혼합처리가 현격하게 높은 살충력을 나타냈다.

In general, auto parts production assembly line is assembled and produced by automatic mounting by an automated robot. In such a production site, quality problems such as misalignment of parts (doors, trunks, roofs, etc.) to be assembled with the vehicle body or collision between assembly robots and components are often caused. In order to solve such a problem, the quality of parts is manually inspected by using mechanical jig devices outside the automated production line. Automotive inspection technology is the most commonly used field of vision, which includes surface inspection such as mounting hole spacing and defect detection, body panel dents and bends. It is used for guiding, providing location information to the robot controller to adjust the robot's path to improve process productivity and manufacturing flexibility. The most difficult weighing and measuring technology is to calibrate the surface analysis and position and characteristics between parts by storing images of the part to be measured that enters the camera's field of view mounted on the side or top of the part. The problem of the machine vision device applied to the automobile production line is that the lighting conditions inside the factory are severely changed due to various weather changes such as morning-evening, rainy days and sunny days through the exterior window of the assembly production plant. In addition, since the material of the vehicle body parts is a steel sheet, the reflection of light is very severe, which causes a problem in that the quality of the captured image is greatly changed even with a small light change. In this study, the distance between the car body and the door part and the door are acquired by the measuring device combining the laser slit light source and the LED pattern light source. The result is transferred to the joint robot for assembling parts at the optimum position between parts, and the assembly is done at the optimal position by changing the angle and step.

Korea has produced large quantities of Panax Ginseng roots which have a stimulating effect on the metabolisma of protein, lipid and nucleic acids in the body. Authors believe that the lear and trunk of Panax Ginseng might have some components possessing a similar activity to Panax Ginseng root although the quantity and quality of the functional components may be somewhat different. Therefore, this study was designed to observe the nutritional effects of diet supplemented with the leaves or trunks of Panax Ginseng. Weanling(body weight; $82{\pm}3g$) male albino rats were subjected to six different dietary groups as followings; A groups; dietary groups which were treated with steam for 30 min at $115^{\circ}C}$. B Groups; dietary groups which were not treated with steam. A-C (or B-C) dietary group; Control for A groups(or B groups) containing 99% wheat flour. A-1 (or B-1) dietary group; dietary group supplemented with 2% leaf of Panax Ginseng, which replaced 2% wheat flour of control diet. A-2 (or B-2) dietary group; dietary group supplemented with 2% trunk of Panax Ginseng, which replaced 2% wheat flour or control diet. Each group of rats was maintained with the corresponding diet for 40 days. And then they were sacrificed. The growth rate, protein efficiency ratio, and the contents of lipid and cholesterol in organs were determined. The results obtained are summarized as follows;1) The gained body weights of dietary group supplemented with 2% leaf(A-1 and B-1) or 2% trunk(A-2 and B-2) of panax Ginseng were more increased in comparison to the corresponding control group(A-C and B-C). 2) The gained body weight of each group in A-group(A-C, A-I and A-2) was higher than that or each corresponding dietary group in B-group(B-C, B-1 and B-2). 3) The protein efficiency ratios of A-1 and A-2 dietary group, and B-1 and B-2 dietary group were more improved in comparison to the corresponding control group(A-C and B­C). 4) The lipid contents in the liver of A-1 and B-1 dietary groups were lower than in that of A-C and. B-C dietary group, respectively. According to the above results, it could be suggested that the nutritional value of the wheat flour can be improved by supplement of 2% leaf or 2% trunk of Panax Ginseng.

This study investigates the characteristics of Nordic sweaters works from a historical perspective. Specifically, this study deals with the following research topics: 1) development of Nordic sweaters, 2) the characteristics of Nordic sweaters industry according to the change of times, 3) the comparison of local knitting patterns, 4) the symbolic meaning of the designs in the Nordic sweaters and patterns. The results of the study are summarized as follows. 1. Knitted work developed mostly in Northern Europe, a cold area, and the barren, mountainous coastal areas where people frequently used woolen materials for clothes. It was also developed in Scandinavian regions which lead the fashion in modern days. Scandinavian knitting techniques have been diffused into the east coast of England and Northern Europe by Vikings. 2. Scandinavian countries are distinguished from other countries by their conservative but creative cultural tradition. Their knitting patterns are characterized by small geometric figures such as dots, triangles, squares, rhombuses, and crosses used often with stars and roses. Scandinavian knitting is also salient for its vertical stripes and simple motifs repeating at short intervals. 1) Norway ; Simple and geometric Norwegian patterns are classified into three groups of motifs: (a) the motifs of cross, diamond, X, and swastika (equation omitted). (b) the motifs of human figures, animals and birds, (c) floral motifs (especially eight-petal roses). Their use of color is also simple, and is limited to more than two colors. (2) Sweden ; Swedish patterns are colorful and geometric. They are characterized by features such as brocade, complex embroidery, and contrast of red and black colors. They also show Guernsey patterns. Initials and production years were knitted in sweaters which have different patterns in their trunks and sleeves. 3) Denmark ; The Danish pattern is the purl stitch knitted against the stockinette stitch. The technique is used to copy woven damask motifs. The patterns are seen most clearly when they are knit with smooth yarn. The Faeroe sweaters are the representative work of Danish knitting. Faeroe knitting, incorporates stranded pattern and is knit in the round, either with circular needles. 4) Finland ; Finnish patterns are similar to Norwegian patterns. Finnish knitted work show very colorful, variety and free-flowing geometric patterns. 5) Iceland ; Icelandic knitting shows original ribbon pattern. Lope sweater is the representative work. 3. The traditional knitting patterns not only carried symbolic meanings but also served as means of communication. First of all, patterns had incantatory meanings. Patterns were symbolic of one's social standing, too. The colors, motifs and their arrangements were very important features symbolizing one's social position or family line. People often communicated by certain pieces of knitted work or patterns. In short, the knitted work in the Nordic sweaters served the function of admiring the beauty of nature and symbolizing various meanings. The unique designs and colors of the knitted work reflected the characteristics of the culture those works belonged to. This study also turns our attention to the issue of how the traditional colors and designs of the knitted work can contribute to the development of modern designs, and by doing so, if makes us realize the importance of knitted works in modern society.

For years, physicians and anatomists have been interested in the heart that has one functioning ventricle. Various terms have been suggested for this entity including single ventricle, common ventricle, double-inlet left ventricle, cor biatriatum triloculare, and primitive ventricle. In this report, the term "single ventricle" is utilized as suggested by Van Praagh, and is defined as that congenital cardiac anomaly in which a common or separate atrioventricular valves open into a ventricular chamber from which both great arterial trunks emerge. An outlet chamber, or infundibulum, may or may not be present and give rise to the origin of either of the great arteries. This definition excludes the entity of mitral and tricuspid atresia. An 11 year old cyanotic boy was admitted chief complaints of exertional dyspnea and frequent upper respiratory infection since 2 weeks after birth. He was diagnosed as inoperable cyanotic congenital heart disease, and remained without any corrective treatment up to his age of 11 year when he suffered from aggravation of symptoms and signs of congestive heart failure for 2 months before this admission. On 22nd of May 1979, he was admitted for total corrective operation under the impression of tricuspid atresia suggested by a pediatrician. Physical check revealed deep cyanosis with finger and toe clubbing, and grade V systolic ejection murmur with single second heart sound was audible at the left 3rd intercostal space. Development was moderate in height [135 cm] and weight[28Kg]. Routine lab findings were normal except increased hemoglobin [21.1gm%], hematocrit [64 %], and left axis deviation with left ventricular hypertrophy on EKG. Cardiac catheterization and angiography revealed 1-transposition of aorta, pulmonic valvular stenosis, double inlet of a single ventricle with d-loop, and normal atriovisceral relationship [Type III C solitus according to the classification of Van Praagh]. At operation, longitudinal incision at the outflow tract of right ventricle in between the right coronary artery and its branch [LAD from RCA] revealed high far anterior aortic valve which had fibrous continuity with mitral annulus, and pulmonic valve was stenotic up to 4 mm in diameter positioned posterolaterally to the aorta. Ventricular septum was totally defective, and one markedly hypertrophied moderator band originated from crista supraventricularis was connected down to the imaginary septum of the ventricular cavity as a pseudoseptum of the ventricle. Size of the defect was 3X3 cm2 in total. Patch closure of the defect with a Teflon felt of 3.5 x 4 cm2 was done with interrupted multiple sutures after cut off of the moderator band, which was resutured to the artificial septum after reconstruction of the ventricular septum. Pulmonic valvotomy was done from 4 mm to 11 mm in diameter thru another pulmonary arteriotomy incision, and right ventriculotomy wound was closed reconstructing the right ventricular outflow tract with pericardial autograft of 3 x 4 cm2. Atrial septal defect of 2 cm in diameter was closed with 3-0 Erdeck suture, and atrial wall was sutured also when rectal temperature reached from 24`C to 35.5`C. Complete A-V block was managed with temporary external pacemaker with a pacing rate of 110/min. thru myocardial wire, and arterial blood pressure of 80/50 mmHg was maintained with Isuprel or Dopamine dripping under the CVP of 25-cm saline. Consciousness was recovered one hour after the operation when his blood pressure reached 100 /70 mmHg, but vital signs were not stable, and bleeding from the pericardial drainage and complete anuria were persisted until his heart could not capture the pacemaker impulse, and patient died of low output syndrome 320 min after the operation.

포도나무의 추위피해는 여러 형태로 나타난다. 월동피해 중에는 기계적 피해, 동해 또는 수세의 약화 원인이 된다. 본 연구는 '거봉'의 뿌리혹병의 피해를 억제하기 위하여 저항성 대목의 선발과 월동법 개선을 통한 방제법을 개발하기 위하여 실시하였다. SO4, 5BB, 3306대목에 $10^4cfu/ml$의 뿌리혹병균(YK2823, YK3312, LMG259, HKA234)을 접종했을 때는 혹이 발병하지 않았으나 $10^6cfu/ml$의 높은 농도에서는 모든 대목에서 혹이 형성된다. 그러나 혹의 크기는 거봉에서보다 매우 작았다. 인공접종에 의하여 3품종의 뿌리혹병 저항성 대목을 선발하였다. 볏짚과 보온덮개로 줄기와 가지에 피복하는 월동법은 뿌리 혹병을 예방하는데 가장 효과적이었다. 이러한 처리방법은 포도나무가 월동하는 동안 수체의 온도 차이가 $9.6^{\circ}C$로 온도변화가 최소화되었고 동해발생이 없어 정상적으로 생육하였다.
