Purpose: To evaluate stability and effects of photochromic lenses in light-sensitive patients. Methods: Analyzing 65 patients, this research employed a standardized survey, fundus examination, and slit-lamp biomicroscopy to evaluate the changes in photophobia, tears, asthenopia, and the deterioration of outdoor visual acuity after wearing photochromic lenses for one month. Measurement of visual acuity was performed outdoors at noon on a bright day using Dr. Hahn’s standard test chart for 3 m. Results: Photochromic lenses, considerably decreased photophobia, tears, and asthenopia. The “normal” visual acuity of 38 patients was established without photochromic lenses. Re-examination after the lenses had been worn for a specified period of time showed that 29 subjects could discern at least one line higher than their “normal” acuity. Conclusions: Photochromic lenses reduced photophobia and the disabling effect of bright light such that comfort was increased. Not only did the lenses improve vision, they also enhanced the overall quality of vision.

Purpose: To assess the changes of retinal function together with recovery progress in a patient with Vogt-Koyanaki-Harada syndrome using a multifocal electroretinogram (mfERG). Methods: The retinal changes of a 32-year-old woman diagnosed with Vogt-Koyanaki-Harada syndrome have been investigated and compared for different times such as before treatment and 3 and 6 months after treatment using a fluorescein angiogram, electroretinogram (ERG) and mfERG. Results: As time passed, the patient`s visual acuity was recovered, the serous retinal detachment in the posterior pole was restored, and the phenomenon of late subretinal leakage disappeared on fluorescein angiogram, while aggregation and atrophy of the retinal pigment epithelium were detected. The early-stage responses of the retina decreased on ERG; however, it has gradually recovered and was determined to be normal after 6 months. Responses measured on the mfERG have increased during the 6 months after surgery compared to the pre-treatment, but there was still a partial lack of response. Conclusions: In this case, the abnormal condition of retinal function existed continuously on the mfERG, even when the serous retinal detachment in the posterior pole was recovered. In this regard, a long-term systematic investigation and subsequent mfERG treatment have been thought to be necessary for patients with this disease.

본 논문에서는 음성 스펙트럼 정보를 효율적으로 부호화할 수 있는 벡터양자화기 구조를 제안한다. 제안한 구조는 벡터 양자기의 단점인 탐색 계산요구량을 줄이기 위하여 분리 구조와 다단계 구조를 결합시키고 선형예측부호기 (LPC: Linear Predictive Coding) 계수에서 변환된 선 스펙트럼 쌍 (LSP: Line Spectrum Pair) 파라메타의 분포 특성을 효율적으로 이용할 수 있는 예측 구조를 갖는다. 제안한 구조의 부호책 설계방식으로 M-탐색(M-search) 공동 최적화 알고리듬을 적용하고, 왜곡 측정지준이 WMSE(Weighed Mean Squared Error)일 때 다단계 벡터 양자기 구조의 각 단계의 분할에 대한 중앙값 결정 방법을 제시한다.

본 연구는 기술에 대한 이해와 경험의 정도가 높은 IT종사자들이 모바일 상거래와 같은 혁신에 대한 저항에 있어서 비IT 종사자과 비교하여 어떤 차이가 있는지를 살펴보고자 하였다. 모바일 상거래에 대한 인식을 대상으로 하였다. 총 317명의 설문결과는 IT인력이 모바일 상거래에 저항하는 요인으로는 지각된 위험, 적합성, 복잡성이 확인되었으며, 비IT인력의 경우 상대적 이점, 적합성, 복잡성이 주요 요인이었다. 그리고 모바일 상거래의 두 집단 모두의 결과에서 혁신저항이 클수록 사용의도가 낮게 나타났다. This study investigates the differences between IT workers, who possess a high understanding of technology, and non-IT workers in the resistance to accepting an innovative service like mobile commerce. From a total of 317 survey respondents, the results of the study revealed that perceived risk, compatability, and complexity were the significant factors for resistance to mobile commerce for IT workers, while relative advantage, compatibility, and complexity were the factors of resistance for non-IT workers. Higher innovation resistance was shown to result in lower intention of use for both groups of mobile commerce users.

Space in the past had characteristics of place which are required for specific behavior to be done as we recognized it easily. However, for space in modern times, the purpose, forms and behavior space has, have changed as tools comprising the space have changed. ‘Virtual space’ which has been a conversation topic recently is unspecific and changeable space whose forms and geological location are not defined clearly. In addition, behaviors caused by this virtual space in combination with real space are taking place. The nature of Flash Mob which is one of the typical behaviors which take place starting from virtual space to be connected with real space, is that it is intangible game culture whose forms and behaviors are not fixed, and it is not limited to a specific place. Besides, Flash Mob is characteristic of representing game culture in modern society, and its nature can be summarized as temporariness, non-placeness, anonymity, double-sidedness and so forth. Since events generally take place in every place when man is involved in space, it’s possible to generally think events derived from interpersonal relationships between man and man. We are to study spatial characteristics of Flash Mob by analyzing features and cases of the Flash Mob by means of them.

Large economic losses have been reported by root-knot nematide, Meloidogyne incognita, in Korea. However, fewy environmentally-friendly nematicide alternatives for the control of M. incognita have been developed. This study was conducted of Korean native plants to screen nematicidal activity which could be used by organic farmers. Methanol extracts (1,000 ㎎ L?¹) from fifty-three Korean native plants were applied to 24-well tissue culture testplates containing 1 × 10² M incognita and the nematicidal activities were determined, Nematicidal activities of the methanol extracts in common purslain (Portulaca oleraceae L.) and water mouse-ear-chickweed (Stellaria aquatica Scop.) were 60.0% and 40.6%, respectively, compared with that of control, however, those of other forty-one plants were less than 30%. Our results suggest that the methanol extracts of common purslain and water mouse-ear-chickweed contain nematicidal active compounds.
