디지털 게임 경험에 있어 몰입은 가장 중요한 요인이다. 그러나 일부 게임은 다양한 방법으로 플레이어의 몰입을 흩트리고 이로 인한 심리적 거리감을 말미암아 성찰의 기회를 부여한다. 이러한 전략은 '낯설게 하기' 기법과 유사한 측면이 있다. 이에 본고는 디지털 게임의 반몰입 전략의 특성과 유형을 검토하고, 이를 '감각정보의 교란', '서사의 반전 및 장르의 전복', '경험의 제한' 세 가지로 제시하였다. 분석 결과, 시청각적 정보의 과잉, 축적된 정보나 장르 문법을 낯설게 하기, 특정한 선택과 경험의 강요는 반몰입 유발에 효과적인 것으로 나타났다. 해당 연구는 대안적 게임의 반몰입 전략을 정리하였다는 점에서 의의가 있다.

This study was conducted to select representative agricultural products (4 types of fruits and 4 types of wild vegetables) in Chungju, define their sensual characteristics, derive suitable flavour-pairing and recipes for each ingredient, and use them as a cornerstone in the development of menus. For the experiment, 10 experts were selected to choose 8 representative agricultural products in Chungju, and 18 menus were selected through a flavour-pairing survey. A consumer panel (a total of 413 people, 105 in their 20s, 103 in their 30s, 103 in their 40s, and 102 in their 50s) for evaluating the characteristics of consumer preferences was selected. After the flavour-pairing survey 'sweet taste', 'light flavour', 'soft flavour', 'savoury flavour', 'familiar flavour', 'harmonious flavour', 'softness', and 'harmoniousness with food ingredients' were determined as drivers of liking, on the other hand, 'disturbance with food ingredients' and 'soybean fishy smell' were determined as drivers of disliking. The degree of consumer preference and overall acceptance were found to be related to the consumers' familiarity, suggesting that if a menu should be developed using unfamiliar local agricultural products, it should be configured with familiar recipes and seasoning methods.

대상포진(Herpes Zoster:HZ)은 수두 대상포진 바이러스(Varicella Zoster virus)에 의해 야기된 속발성 또는 잠복성 감염이다. 증령에 따라 바이러스 특이적 면역 및 세포 매개 면역력이 감소하면서 바이러스가 재활성화되기 때문에, 대상포진은 주로 노년층에서 호발한다. 대상포진에 이환되면, 극심한 급성 통증이 발생하게 되고 수개월에 걸쳐서 회복하게 된다. 포진후신경통(Postherpetic neuralgia:PNH)은 대상포진의 대표적인 합병증의 하나로, 대상포진에 이환된 후 발생한 통증이 3개월 이상 회복되지 않을 때, 포진후신경통으로 진단할 수 있다. 임상적 증상으로는 주기적으로 찌르는 듯한 통증이 동반되는 타는 듯한 통증, 이질통이 발생할 수 있으며, 감각저하 또는 지각이상을 보일 수 있다. $Neurometer^{(R)}$(neuroselective sensory nerve conduction threshold: sNCT, Automated current perception threshold: CPT, neurotron incorporated. Baltimore, Maryland. 21209 U.S.A.)는 신경의 감각이상을 평가하는 데 유용하게 쓰이는 평가기구이다. 이번 증례는 포진후신경통을 주소로 내원한 환자의 치료 증례를 통해, 포진후신경통의 발생기전을 고찰해보고, 그 치료법에 대하여 알아보고, 또한 치료과정 중의 경과관찰 방법으로서 $Neurometer^{(R)}$를 이용하여, 감각이상의 평가 및 경과관찰시 지각이상에 대한 정량적인 평가를 시도하였다.

Purpose: The goals of a blow-out fracture reconstruction are to restore the osseous continuity, provide support for the orbital contents and prevent functional and anatomic defects. Over the past several years, a range of autogenous and synthetic implants have been used extensively in orbital reconstructions. None of these implants have any absolute indications or contraindications in certain clinical settings. However, in extensive blow-out fractures, it is difficult to restore support of the orbital contents, which can cause more complications, such as enophthalmos. This study examined the clinical outcomes of extensive or comminuted blow-out fractures that were reconstructed by the simultaneous use of a titanium mesh plate and $Medpor^{(R)}$. Methods: Eighty six patients with extensive orbital fractures, who were admitted between March 1999 and February 2007, were reviewed retrospectively. The patients' chart and CT were inspected for review. Twenty three patients were operated on with both a titanium mesh plate (Matrix MIDFACE pre-formed orbital plate, Synthes, USA) and $Medpor^{(R)}$ (Porex, GA, USA). The patients underwent pre-operative CT scans to evaluate the fracture site and measure the area of the fracture. A transconjunctival approach was used, and titanium mesh plates were inserted subperiosteally with screw fixation. $Medpor^{(R)}$ was inserted above the titanium mesh plate. The patients were evaluated post-operatively for enophthalmos, diplopia, sensory disturbances and eyeball movement for a period of at least 6 months. Results: No implant-related complications were encountered during the follow-up period. Enophthalmos occurred in 1 patient, 1 patient had permanent sensory disturbance, and 3 patients complained of ocular pain and fatigue, which recovered without treatment. Although there were no significance differences between groups, the use of 2 implants had fewer complications. Therefore, it can be an alternative method for treating blow out fractures. Conclusion: The use of both a titanium mesh plate and $Medpor^{(R)}$ simultaneously may be a safe and acceptable technique in the reconstruction of extensive blow-out fractures.

Objective : Disc herniations at the L1-L2 and L2-L3 levels are different from those at lower levels of the lumbar spine with regard to clinical characteristics and surgical outcome. Spinal canals are narrower than those of lower levels, which may compromise multiple spinal nerve roots or conus medullaris. The aim of this study was to evaluate the clinical features and surgical outcomes of upper lumbar disc herniations. Methods : We retrospectively reviewed the clinical features of 41 patients who had undergone surgery for single disc herniations at the L1-L2 and L2-3 levels from 1998 to 2007. The affected levels were L1-L2 in 14 patients and L2-L3 in 27 patients. Presenting symptoms and signs, patient characteristics, radiologic findings, operative methods, and surgical outcomes were investigated. Results : The mean age of patients with upper lumbar disc was 55.5 years (ranged 31 to 78). The mean follow-up period was 16.6 months. Most patients complained of back and buttock pain (38 patients, 92%), and radiating pain in areas such as the anterior or anterolateral aspect of the thigh (32 patients, 78%). Weakness of lower extremities was observed in 16 patients (39%) and sensory disturbance was presented in 19 patients (46%). Only 6 patients (14%) had undergone previous lumbar disc surgery. Discectomy was performed using three methods : unilateral laminectomy in 27 cases, bilateral laminectomy in 3 cases, and the transdural approach in 11 cases, which were performed through total laminectomy in 10 cases and unilateral laminectomy in 1 case. With regard to surgical outcomes, preoperative symptoms improved significantly in 33 patients (80.5%), partially in 7 patients (17%), and were aggravated in 1 patient (2.5%). Conclusion : Clinical features of disc herniations at the L1-L2 and L2-L3 levels were variable, and localized sensory change or pain was rarely demonstrated. In most cases, the discectomy was performed successfully by conventional posterior laminectomy. On the other hand, in large central broad based disc herniation, when the neural elements are severely compromised, the posterior transdural approach could be an alternative.

Purpose: The first web space of the foot has a similar thickness and skin texture of the pulp of the fingers. Moreover, it has a reliable blood vessel and sensory nerve. The purpose of this study was to evaluate the clinical results of the first web space free flap to reconstruct the pulp of fingers. Materials and Methods: Authors have performed 23 cases of first web space free flap to reconstruct the pulp defect of the fingers between June 2004 and May 2009. The age of the patients ranged from 20 years old to 55 years old. The size of the flap ranged from $1{\times}1.5cm$ to $8.5{\times}2.5cm$. The mean flap area was 5.4 cm2. In 4 cases, we elevated the flap including lateral aspect of the big toe and medial aspect of the second toe. And then we made an artificial syndactyly to reconstruct the pulps on two fingers at the same time. In all cases, we performed 1 digital artery and 1 dorsal vein anastomosis. Every donor site that had a small defect healed spontaneously without any additional operations to cover it. Results: Of this type of surgery 21 flaps (91.3%) survived, 2 flaps (8.7%) failed. There was no severe complication in the donor sites. There was no walking disturbance due to the skin defect of the donor site. The static 2 point discrimination in 11 cases that we could check ranged from 3 mm to 15 mm. Conclusion: The authors believe that the first web space free flap of the foot is a good option for the reconstruction of the pulp of the fingers and it has a minimal donor site morbidity.

Purpose: Study was to evaluate the operative results for tarsal coalition with tarsal tunnel syndrome. Materials and Methods: From Jan. 2005 to Mar. 2006, among a number of patients who were diagnosed with tarsal tunnel syndrome caused by tarsal coalition and treated surgically, 5 patients were closely observed for more than 12 months. All cases were talocalcaneal coalition and there were two male and three female patients with a mean age of 36 years (22-50 years). We used the Takakura rating scale as clinical evaluation. Results: All five patients had a burning pain in the sole or extended to toes and showed positive Tinel's sign. Sensory disturbances were observed in the distribution of the medial plantar nerves in four patients and in the area of the medial and lateral plantar nerves in one. Atrophy and weakness of the plantar muscles were seen in two patients. The mean Takakura scale in preoperative and postoperative was 3.4 points (1 to 5 points), 8.6 point (6 to 10 points). The mean follow up was 14.4 months (12 to 16 months). The postoperative results were excellent in two patients, good in two and fair in one. As postoperative complications, there were persistent swelling in one patient and a flexion disturbance of Hallux in one. Conclusion: The coalition resection performed on tarsal tunnel syndrome caused by tarsal coalition could improve a level of pains and neurological symptoms significantly. However, since there were some undesirable complications, a detailed explanation to patients is required prior to surgical treatment and study of such complications may be required.

Purpose : Cerebrovascular disease is the most frequent cause of death in Korea and it remains severe disabilities disturbing normal life, According to the previous studies, mortality of the stroke in the first one week is up to the 20% and 95% of stroke patients in the acute stage are accompanied by more than one complications. These complications affect not only the acute stage mortality but also the late stage rehabilitations. In Korea the oriental medicine is preformed in the treatment of stroke. Therefore it is important to recognize thoroughly the complications in the acute stage of stroke and to prevent them. But studies about complications of acute stage stroke is rarely presented in the fields of oriental medicine. So this study is prepared for investigating the characteristics and frequency of complications in the acute stage of stroke. And we are to assess the importance of theses acute complications by systemic reviewing the previous studies. Methods : Fifty one patients are included who had been admitted to ICU(intensive care unit) of Chenju Hospital of Wonkwang Oriental Medicine. Twenty nine patients are diagnosed as ischemic stroke and twenty one patients are diagnosed hemorrhagic stroke. Medical and neurological complications were investigated retrospectively based on medical notes excluding primary symptoms of stroke Le. motor weakness, sensory disturbance and speech disorder. And risk factors of stroke such as D.M. or hypertension are excluded. Results : Medical complications are more frequent than neurological ones. Most frequent medical complication is dysuria(61%) and constipation(45%), fever(30%) and aspiration pneumonia(22%) are followed in order of frequency. In Neurological complication dysphagia(56%), the exacerbation of infarction due to increased intracranial pressure(24%), irritability or insomnia(21%) is most frequently complicated in order of frequency. Conclusions : These complications are mostly caused by bed rest state in acute stage stroke. It is supposed that more aggressive management can prevent theses ones. And it is possible to improve the medical and neurological conditions by sticking theses study results.

Neurilemmomas are the most common benign tumor of the peripheral nerve trunks, and arises from the cells in the sheath of Schwann. Neurilemmomas are well encapsulated and may be separated easily from surrounding tissue and lie completely within a larger nerve trunk, with bundles of neurofibrils spread out over the surface of the tumor. A careful dissection and retraction of the nerve bundles will allow the tumor to be enucleated from the parent nerve without any significant interference with the function of the nerve. Resection of the involved nerve is seldom necessary and should be avoided if at all possible. Our aim in microscopic excision of neurilemmoma of extremities is to reduce any disturbance of the intact neurofibrils of the parent nerve. Thirteen cases of neurilimmomas were treated by microscopic excision at the Department of Orthopaedic Surgery, Korea University Hospital between January 1990 and March 1995. The results was as follows ; 1. The average age at surgical intervention was 40.1 years. Cases in fourth and fifth decades predominated. 2. In their anatomical distribution, 8 cases were in the upper extremity and 5 cases in the lower extremity. 11 cases were on the flexor surface. 3. On the operative field, all the tumors were well encapsulated, however 1 case of 13 was adherent to the periosteum of fibula. 4. In all cases, the tumor were enucleated from the parent nerve without any injury to nerve under high-power magnification, preserving individual fascicles, and sensory and motor function.

Purpose: The soft tissue injuries of the patellar area are difficult problems because of insufficient arterial blood supply and lack of muscle layer. There have been many methods for reconstructing the soft tissue injuries of the patellar area such as primary closure, skin graft, local flap and free tissue transfer. However, each method has some limitations in their application. After the first introduction, the fasciocutaneous flaps are widely used to reconstruct the soft tissue injuries. The saphenous nerve, one of the superficial sensory nerves in the lower leg, is supplied by the saphenous artery and its vascular network. We used the saphenous fasciocutaneous island flap to reconstruct the soft tissue injuries of the patellar area. Methods: From March 2002 to May 2005, we used the saphenous fasciocutaneous island flap to reconstruct the soft tissue injuries of the patellar area. The flap was elevated with saphenous nerve, saphenous vein and saphenous artery and its vascular network. The flap donor site was reconstructed with primary closure or split-thickness skin graft. Results: Five cases survived completely but 1 case developed partial necrosis of the skin on the upper margin of the flap. However, the necrosis was localized on skin layer, and we reconstructed with debridement and split-thickness skin graft only. After the operation, there was no contracture or gait disturbance in any patient. Conclusion: In conclusion, the saphenous fasciocutaneous island flap is safe, comfortable and effective method to reconstruct the soft tissue injuries of the patellar area.
