전남 신안군의 퉁퉁마디 재배지에서 대 발생하여 피해를 초래한 해충이 뿔나방과의 Scrobipalpa salinella (Zeller)로 확인되었다. 본 종은 Park & Ponomarenko (2006)에 의해 국내에서 처음 보고된 바 있다. 그러나 동정이 어려운 암컷 한 개체를 대상으로 하였으며, 염생식물이 없는 산간지역에서 발견된 점 등으로 분포에 대한 의문점이 상존해 왔었으나 금번 조사결과로 국내 분포가 재 확인되었다. 종의 분류동정을 위한 성충과 생식기의 사진 제공과 함께 유충의 발생 및 피해에 대해 조사된 내용을 기술하였다. In a cultivated field of Salicornia europae in the Jeonam Province, Korea, Scrobipalpa salinella (Lepidoptera, Gelechiidae) which feeds and leads to a serious damage was found. The discovery of this species is to reconfirm its distribution in Korea because the first report by Park and Ponomarenko (2006) was based on a single female and it was collected in a montane area far from seaside where its host plants, halophytes, are planted. For identification, photos of imago and genitalia are given, and the damage by larvae on Salicornia europae are noted.

In the partial squeeze casting process, the filling behavior of liquid metal and solidification pattern in thick area have significant influence on the quality of casting products and die life. For the optimal casting design of automobile transmission gear housing, various analyses were performed in this study by using computer simulation code, MAGMAsoft and the simulation results were compared and analyzed with experimental results. By air pressure criteria, internal porosities caused by air entrap during the mold filling were predicted and reduced remarkably by modification of gating system. Also, optimal squeeze-time lag to apply partial squeeze pin in thick area was calculated and the castings was free from shrinkage defects with the result of solidification analysis. Consequently, casting design for automobile transmission gear housing was optimized and approved by Computer Tomography.

In this study, the effect of chill layers occurred in shot sleeve on the molten metal filling was analyzed through computer simulation. The behavior of chill layers with temperature variation of shot sleeve set from 200 to $280^{\circ}C$ was also investigated. The simulation results showed the chill layers set in the in-gates during the injection process change the main filling direction and cause turbulent flow pattern, resulting in porosities inside the castings. The amount of chill layers with the increasing temperature of shot sleeve was considerably reduced. Particularly, at the setting temperature of $280^{\circ}C$ by heat control unit, the biggest reduction in chill layers, excellent trimmed surface and the highest density were achieved, suggesting that as the optimal sleeve condition in aluminum high pressure diecasting, especially for highly complex parts like valve body.

Purpose: The purpose of this study was to investigate the effect of whole body vibration combined breathing resistance on lung capacity and respiratory muscle and to suggest a mediation method for improvement of respiratory function and lung function in the future. Methods: This study was a preliminary study design of two groups of 54 healthy young adults who were randomly assigned to an experimental group (n=27) with core exercise combined with respiratory resistance and whole body vibration and a control group with respiratory resistance and core exercise (n=27). All interventions consisted of 6 core exercises every 40 seconds and rest for 20 seconds. To compare the effects of intervention, we measured spirometry and respiratory muscle strength. Results: Both the experimental group and the control group showed a significant increase in Forced vital capacity (FVC) and Maximum voluntary ventilation (MVV) (p<.05). However, FEV1 and FEV1% were significantly increase only in the experimental group (p<.05). FVC, FEV1%, Maximum Inspiratory Pressure (MIP), Maximum Expiratory Pressure (MEP) showed more significant increase in the experimental group than the control group. Conclusion: These findings indicate that whole-body vibration combined breathing resistance is an effective intervention for people, with FVC, FEV1%, MIP, MEP increase.

Objectives:The objective of this study is to find out the differences in psychopathology, temperament, and character factors between young adults with and without childhood attention-deficit hyperactivity disorder (ADHD) symptoms. Methods:The subjects consisted of 314 university students (male=72, female=242) in Gongju. They were divided into childhood ADHD group (N=54) and normal group (N=260) to the Wender-Utah Rating Scale. Participants were assessed using Korean Adult ADHD Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Kimberly Young’s Internet Addiction Test, Barratt Impulsiveness Scale, Paranoia Scale, Korean-Schizotypal Ambivalence Scale, Lubben Social Network Scale, and Temperament and Character Inventory-Revised. Descriptive statistics, t-test, chi-square, spearman correlation, and stepwise multiple regression were applied to analyze the data. Results:Participants with childhood ADHD symptoms had high level of adult ADHD symptoms (p<.001), impulsiveness(p=.001), depression (p<.001), anxiety (p<.001), internet addiction (p<.001), paranoia tendency (p<.001) and low level of selfesteem (p<.001) compared to normal group. Self-directedness (p<.001) was lower, Harm avoidance (p=.001) and Self-transcendence (p=.029) were higher in the childhood ADHD group. In correlation and stepwise multiple regression, childhood ADHD symptoms were significantly associated with cooperativeness (r=-0.515 and β=-0.547, p<.001 respectively). Conclusion:This result showed that young adults with childhood ADHD symptoms had various forms of psychopathology and childhood ADHD symptoms were influenced by character such as cooperativeness. Therefore, more thorough evaluation regarding childhood ADHD symptoms is needed.

박진영,박종균,Park, Jin-Young,Park, Jong-Kyun 한국잔디학회 2011 한국잔디학회지 Vol.25 No.2

본 연구는 우리나라 산림지역에서 유일하게 잔디가 식재되어 있는 집단묘지에서 출현하는 곤충을 조사하였다. 그 결과 총 11목 39과 77속 86종이 조사되었으며, 그 중 노린재목(Hemiptera)이 25종(29.1%)으로 가장 많은 종수를 나타내었으며, 다음으로 딱정벌레목(Coleoptera)이 17종(19.8%), 메뚜기목(Orthoptera) 13종(15.1%), 나비목(Lepidoptera) 11종(12.8%), 잠자리목(Odonata) 5종(5.8%), 벌목(Hymenoptera) 4종(4.7%), 파리목(Diptera) 2종(2.3%), 바퀴목(Blattaria), 사마귀목(Mantodea), 집게벌레목(Dermaptera)이 각각 1종(1.2%) 순으로 조사되었다. 노린재목(Hemiptera)과 메뚜기목(Orthoptera)의 출현이 많은 것은 대부분 조사지의 식물상이 잔디와 더불어 서식하는 억새풀, 띠풀, 넝쿨딸기 그리고 가시박, 칡 등 키 작은 화본과 식물, 개망초, 바랭이, 호밀풀 등의 초본식물로 구성된 초지형태로 식식성 곤충들에게 적합한 서식처이기 때문으로 판단된다. 조사지점별 분석에서 도로변과 인접하고 여러 가지 인공적인 영향(St. 1)으로 곤충의 다양성이 묘지 중앙이나 산림과 인접한 조사지(St. 2, 3)보다 상대적으로 낮은 다양성을 보였다. 비록 산림내에서 적은 부분을 차지하고 있는 묘지지역이지만 잔디구역은 묘지잡초들과 더불어 잔디를 먹이원으로 하는 노린재목, 메뚜기목 곤충들 그리고 이 곤충들을 포식하기 위해 모여드는 사마귀, 딱정벌레류의 포식성 곤충 등, 묘지지역 역시 산림 속 하나의 조그만 생태계를 이루고 있다. 본 연구결과 산림내 잔디지역의 곤충다양성은 주로 식식성 곤충 위주로 분포 되어 있었으며 향후 산림생태계 내에서 잔디지역을 유일하게 포함하고 있고, 인위적으로 잔디지역이 조성되며, 지속적으로 면적이 증가하고 있는 잔디지역의 영향에 대한 후속연구를 위한 기초자료 및 산림생태계 및 산림다양성 연구에 이바지 할 것으로 사료된다. This study was carried out to know the insect fauna of turf grass area in forest. In Korea, graves and public cemetery in mountain areas are usually covered by turf grass which were mainly examined. There were 86 species belonging to 77 genera of 39 families in 11 orders. Among them, site 3 had highest occurrence (38%), second was site 2 (36%) and in the last place was site 1 (26%). Hemiptera revealed best species composition (29.1%) and came Coleoptera (19.8%), Orthoptera (15.1%), Lepidoptera (12.8%) and Odonata (5.8%) etc. The reason why Hemiptera and Orthoptera are mainly found in these areas is because they usually feed on short plants that grow in there. Taxonomic species composition, occurrence ratio by site and species and comparison analysis were provided.

고속 고밀도 WDM 광전송 시스템에서의 ASK-SSB와 PSK-SSB 변조 방식의 성능 분석

박진영,최윤희,박상규,Park Jin-Young,Choi Yoon-Hee,Park Sang-Gyu 대한전자공학회 2004 電子工學會論文誌-TC (Telecommunications) Vol.41 No.12

This research investigates the performance of the optical transmissions systems using the SSB modulation format The focus was on the spectral efficiency of the WDM systems and the transmission penalties due to the fiber nonlinearities. By investigating the performance obtained with ideal SSB signal, we set the upper limit of the performance which can be obtained by SSB technology. Furthermore, we investigated the performance obtainable with SSB signals which can be generated with realizable devices. Since SSB formats are more susceptible to the fiber nonlinearities, SSB formats exhibited inferior transmission performances compared to the DSB format. However, within the 500~1000 km transmission range, which is the focus of this research, it was found that the WDM systems with 12.5 GHz channel spacings might benefit from the SSB modulation techniques. 본 논문에서는 SSB 변조를 이용한 광전송 시스템의 주파수 효율성 및 비선형성에 대한 저항성 등을 규명하였다. 이상적인 SSB 신호를 사용하여 도달할 수 있는 성능의 한계를 확인하는 한편, 실제 제작이 가능한 SSB 변조기가 생성할 수 있는 신호에서 얻을 수 있는 성능을 컴퓨터 시뮬레이션을 통하여 살펴보았다. 이를 통해 SSB 변조된 신호는 일반적으로 DSB 변조된 신호에 비해서 광섬유의 비선형성에 취약하나 본 연구에서 목표로 삼고 있는 전송거리가 500~1000 km 미만인 12.5 GHz 채널 간격의 WDM 시스템에서는 SSB 신호가 DSB 신호에 비해 우수한 성능을 보일 수 있음을 확인하였다.

Intestinal atresia is a frequent cause of intestinal obstruction in the newborn. We reviewed the clinical presentation, associated anomalies, types of atresias, operative managements, and early postoperative complications in 36 cases of intestinal atresia treated at the Department of Surgery, Kyungpook National University Hospital between January 1994 and February 2003. Location of the lesion was duodenum in 17 patients, jejunum in 11 patients and ileum in 8 patients. The male to female ratio was 1:1.4 in duodenal atresia (DA), 2.7:1 in jejunal atresia (JA) and 7:1 in ileal atresia (IA). The most common type was type III (41.1 %) in DA, and type I (52.6 %) in JA and IA. The most common presenting symptoms was vomiting(88.2 %) in DA, but in jejunoileal atresia, vomiting(89.4 %) and abdominal distension(89.4 %) were the most common sign and symptom. All cases of DA were diagnosed by plain abdominal radiography. There were 6 cases of DA with congenital heart disease, 3 cases of DA with Down syndrome and 3 cases of JA with meconium peritonitis. Segmental resection was performed in 13 cases, duodenoduodenostomy in 11 cases, membrane excision in 7 cases, jejunojejunostomy in 2 cases, gastroduodenostomy in 2 cases and ileocolic anastomosis in 1 case. There were 9 postoperative complications including 3 each of anastomotic leakage, wound infection, and intestinal obstruction 3 cases. The mortality rate for DA was 11.8 %(2/17). Both deaths in DA were attributed to congenital heart disease. The mortality rate for JA was 18% (2/11). Both cases died with sepsis and short bowel syndrome.

박진영,안정용,허륭,최훈규,이병희,신문수,정봉섭,Park, Jin Young,Ahn, Jung Yong,Huh, Ryoong,Choi, Hun Kyu,Lee, Byung Hee,Shin, Moon Soo,Chung, Bong Sub 대한신경외과학회 2000 Journal of Korean neurosurgical society Vol.29 No.11

Objectives : Embolization of intracranial aneurysms by using Guglielmi detachable coils(GDC) is proving to be a safe method of protecting aneurysms from rupture. Occasionally, patients with unruptured intracranial aneurysms present with symptoms related to the aneurysm's mass effect on either the brain parenchyma or cranial nerves. In the present study, the authors conducted a retrospective review to evaluate the response to GDC embolization in a series of 6 patients presenting with cranial nerve dysfunction due to mass effect. Patients and Methods : Aneurysms were classified by size, shape, and amount of intraluminal thrombus. Patients were classified by duration of symptoms prior to GDC treatment(range<1 month to>4 years). Clinical assessment was performed within days of the GDC procedure and at later follow-up appointments(range 5-16 months, mean 9 months). Results : In the immediate post-GDC embolization period, one of the five patients had transient worsening of third nerve palsy, which later improved to better than baseline status. Two patients who presented with third nerve deficit from a internal carotid artery-posterior communicating artery junction aneurysm had complete recovery. One patient who presented with hemiparesis and dysarthria from a giant mid-basilar aneurysm showed improvement of these symptoms. One patient who presented with sixth cranial nerve deficit from a cavernous aneurysm showed no change at the 8-months follow-up examination. Conclusion : The endovascular treatment of intracranial aneurysms by using GDC is suggested as an alternative therapeutic method for improving or alleviating neurological deficits produced by mass effect.
