Purpose: This study investigated changes in the angle of exodeviation at different distances and the characteristics of a group that showed an increased angle following monocular occlusion in intermittent exotropia. Methods: In all, 102 patients diagnosed with basic intermittent exotropia were enrolled. The deviation angle was measured using a mirror at 33 cm, 3 m, 6 m, 12 m, and 6 m. Moreover, the deviation was measured at 33 cm and 3 m after patching the non-dominant eye for 1 hour. Patients with a higher deviation angle at 33 cm after occlusion were categorized as the ‘increased group’, whereas those with lower deviation angles were classified as the ‘stationary group’. Results: There was a male-to-female ratio of 46:56 and an average age at surgery of 9.23 years. No significant differences were observed in deviation measurements taken at 3, 6, 12, and 6 m using a mirror. However, after occlusion, there was a significant increase in deviation at 33 cm (p < 0.01). The average log value of near stereoacuity was 1.96 ± 0.35 in the increased group and 2.16 ± 0.41 in the stationary group. The group with an increased near deviation after occlusion demonstrated a significantly improved near stereoacuity (p = 0.01) and an increased proportion of good results in the near Worth 4 dot test (p = 0.03). Conclusions: Preoperative measurement of maximum deviation after 1 hour of monocular occlusion can help reduce recurrence and insufficient correction, particularly in patients with good fusional ability.

rics during 16-17 century. Research was done through the references of exhumed clothing in Chosun Dynesty. Seeing thewaving types of fabrics of flower patterned fabrics of total 108 items, satin damask(Dahn) was 71items, tok the majority.And the next order was twill(Neung) and plain(Ju). It means Dahn was the most popular fabric among the upper classes.It was regarded as one of the noble textiles, because of its luxurious appearance and pleasant touch. Flower patternedplain fabric(Munju) was found only 9items, even though the plain fabric was the most common used type. Asumed forthe reason, Chosun government had restrict to extravagance of the people. In terms of the arrangement of flower pattern,it can be classified into three methods. The most common arrangement method was Arabesque type, followed by openorder shaped type and scattering shaped type. In the repetition of pattern, there were brick-shaped pattern and half droppattern which were spread flower pattern all over the surface of fabric.

목적: 녹내장 환자에서 백내장 수술 후 시신경 및 황반 주위의 RNFL 및 BMO-MRW의 두께 변화와 녹내장의 타입에 따라 백내장 수술에 의한 차이가 있는지, 여기에 미치는 요인은 무엇인지에 대해 알아보고자 하였다. 대상과 방법: 68명의 녹내장 환자들이 포함되었으며 백내장 수술 전후 SD-OCT로 RNFL 및 BMO-MRW 두께 변화를 측정하였다. 폐쇄각과 개방각 녹내장 군으로 나누어 백내장 수술 전후 수치들을 비교하여 분석하였다. 결과: 피험자의 평균 나이는 71.72세였고, 남성 26명, 여성 42명, 개방각 녹내장은 35안, 폐쇄각 녹내장은 33안이었다. 백내장 수술 후 RNFL과 BMO-MRW 두께가 유의미하게 증가하였으며, 폐쇄각 녹내장군에서 백내장 수술 전의 시력이 유의미하게 좋았고, RNFL의 image Q값이 유의미하게 높았다. 다변량 선형 회귀 분석 상 RNFL의 두께 증가에 영향을 미치는 인자는 전체 녹내장 군과 개방각 녹내장 군에서 수술 전의 RNFL 두께였다. 즉, 백내장 수술 전에 RNFL 두께가 얇은 환자일수록 백내장 수술 후 RNFL의 두께가 증가하였다. 폐쇄각 녹내장 군에서는 수술 전 시력이 나쁠수록 수술 후 RNFL의 두께가 증가하였다. 반면 BMO-MRW 두께에 영향을 미치는 인자는 확인되지 않았다. 결론: 백내장 수술 후 RNFL 두께의 증가에 영향을 미치는 인자는 개방각 녹내장 군의 경우 수술 전의 RNFL 두께였으며, 폐쇄각 녹내장 군의 경우 수술 전 시력이었다. Purpose: The aim of this study was to investigate whether there are differences in the effects of cataract surgery based on the type of glaucoma and changes in the retinal nerve fiber layer (RNFL) thickness and Bruch's membrane opening-minimum rim width (BMO-MRW) thickness around the optic nerve and macula in patients with glaucoma. Furthermore, the factors influencing these effects were explored. Methods: 68 patients with glaucoma were enrolled, and changes in RNFL thickness and BMO-MRW before and after cataract surgery were measured using SD-OCT. The patients were divided into angle-closure and open-angle glaucoma groups and values before and after cataract surgery were analyzed. Results: The male-female ratio was 26:42, with an average age of 71.72 years at the time of surgery. There were 35 eyes with open-angle glaucoma and 33 eyes with angle-closure glaucoma. After cataract surgery, both RNFL and BMO-MRW values significantly increased. In the angle-closure glaucoma group, preoperative visual acuity was significantly better and RNFL image Q was significantly higher before cataract surgery. In a multivariate linear regression analysis, the factor influencing the increase in RNFL thickness was found to be the preoperative RNFL thickness in both the overall open angle glaucoma group and the angle closure glaucoma group. In other words, patients with thinner RNFL thickness before cataract surgery showed an increase in RNFL thickness after the surgery. In the angle closure glaucoma group, it was observed that worse preoperative visual acuity was associated with an increase in RNFL thickness after surgery. Conversely, no factors affecting BMO-MRW thickness were identified. Conclusions: The factors influencing the increase in RNFL thickness after cataract surgery were the preoperative RNFL thickness in open angle glaucoma group and the preoperative visual acuity in the angle closure glaucoma group.

전술 MANET에서 그룹 단위 분산된 동적 주소 할당 기법

In this paper, we propose a group distributed dynamic address assignment scheme suitable for tactical mobile ad hoc networks(MANET). Efficient address assignment is an important issue in the MANET because a node may frequently leave the current network and join another network owing to the mobility of the node. The conventional schemes do not consider the features of the tactical networks: existence of a leader node and network activity on a group basis. Thus, they may not be suitable for military operations. In our proposed scheme, called grouped units dynamic address assignment protocol(G-DAAP), a leader node maintains the address information for the members in the network and any of the nodes can exploit the information for the assignment or request of the IP address by a simple message exchange procedure. This leads to fast address assignment with small overheads. In addition, G-DAAP based on the modified IEEE 802.11e Enhanced Distributed Channel Access(EDCA) can assign addresses more quickly. We describe the delay performance of the G-DAAP and compare it with conventional schemes by numerical analysis and computer simulations. The results show that the G-DAAP significantly improves the delay performance as compared with the conventional schemes.

Over the past decades of years, a lot of silks have been unearthed in archaeological excavation, of which the Tang silk fabrics were especially rich and varied. The important ones were from Astana ancient tombs in Turpan, Xinjiang; the Turpan tombs at Reshui, Dulan County, Haixi Prefecture in Qinghai; the underground palace in Famen Monastery at Fufeng County, Shaanxi Province; Mogao grottoes of Dunhuang; and Tokuzshalai site in Bachu County. They were in great numbers. Besides, Shou Sou Yin of Japan has collected a lot of the Tang silk fabrics of the 7-9the centuries. Aurel Stein. and Paul Pelliot stole a great number of Tang silk fabrics from the Mogao grottoes in Dunhuang at the beginning of the 20th century. Chinese scholars have obtained great achievements in the research on the Tang silk fabrics. As early as 1960s Mr. Xia Nai published articles on the structure and patterns of Tang silks. He also made a comparative study between the Tang silks and those of Central and Western Asia. Afterwards, Mr. Wu Min with the Xinjiang Museum, Mdm. Chen Juanjuan with the Beijing Forbidden Palace Museum, and Mr. Zhao Feng also made a thorough study of Tang silks and published their monographs on this subject. Besides, Japanese professionals also obtained conspicuous achievements in this field. This article is a comprehensive study of the structure and patterns of the Tang silks as well as their relations with the Western World on the basis of the above-mentioned scholars' research achievements.

Background: Information on occupation is known as one of the important information sources for socioeconomic and epidemiological research. It can be used to assume socioeconomic status and level of physical activity, to forecast the likelihood of a work-related accident or disease, and to assess the existence and degree of exposure to various risk factors in workplace. Objective: Individual information on occupation is often collected by open-ended questions and then coded into job categories by researchers according to the standard job classification systems. This study aims to assess the reliability among the job codes that three raters independently classified using the information on occupation collected by open-ended questionnaire. Methods: Information on occupation was collected from two surveys with different populations (145 health examinees and 154 college students of open university) with open-ended questionnaire. Two surveys were basically self-administered, but the health examinee survey questionnaire was checked by a trained interviewer. Two occupational classification systems, i.e., the Korean Standard Classification of Occupational (KSCO, 14 categories) and the Korean Standard Industrial Classification (KSIC, 21 categories) were used for job-coding by three junior researchers in the field of public health, The degree of agreement/concordance was assessed by Cohen’s Kappa or Fleiss Kappa and 95% confidence interval (CI). Results: Concordance of job codes among three raters for KSCO was moderate for health examinees (k=0.56, 95% CI=0.52-0.58) and fair for open university students (k=0.34, 95% CI=0.31-0.38). That of KSIC was moderate for both health examinees (k=0.60, 95% CI=0.57-0.63) and open university students (k=0.46, 95% CI=0.43-0.49). There was observed a lot of variation in category-specific kappa values for both KSCO and KSIC classification. Conclusion: Increased concordance of job coding is expected when interview survey is used to collect open-ended questions for the information on occupation and then definite protocol for classification is adopted or to conduct prior education before coding. 연구목적: 본 연구는 연구자 간 직업분류 결과가 얼마나 일치하는지 확인함으로써 직업분류 과정의 신뢰도 평가를 목적으로 한다. 연구방법: 설문 응답자에게 자신이 경험한 직업 중 가장 오래 종사한 직업을 개방형으로 답하도록 하였고, 세 명의 보건학 전공자에게 독립적으로 설문 답변을 직업분류표의 직업 코드로 변환하도록 하였다. 이후 이들의 분류 결과가 얼마나 일치하는지 평가하기 위해 카파통계량을 구하였다. 주요결과: 면접 설문 요원의 개입이 있었던 병원 내원자들을 설문 대상으로 한 경우(n=145), ‘중간 정도’의 일치도를 보였다(한국표준직업분류 14범주: k=0.56, 95% CI=0.52-0.58, 한국표준산업분류 21범주: k=0.60, 95% CI=0.57-0.63). 면접 설문 요원의 개입이 없었던 원격대학 재학생들을 대상으로 한 경우(n=154), ‘중간 미만’ 이나 ‘중간 정도’의 일치도를 보였다(각각, k=0.34, 95% CI=0.31-0.38, k=0.46, 95% CI=0.43-0.49). 결론: 일치도를 높이기 위해서는 직업 종류에 대한 상세한 이해, 코딩을 위한 세부적인 지침 마련, 사전 교육 등이 필요하며, 직업분류 일치도를 해석할 때는 설문 방법 확인, 설문 집단의 연령 분포, 직업 분포, 전문직의 비율 등 다양한 원인을 고려하여 해석할 필요가 있다.
