Purpose: To report a case of verteporfin photodynamic therapy (PDT) for juxtafoveal choroidal neovascularization (CNV) secondary to angioid streaks. Case summary: An 54-year-old male presented with metamorphopsia of the right eye. It was diagnosed as juxtafoveal CNV secondary to angioid streaks and treated with verteporfin PDT-Best corrected visual acuity (BCVA) and macular thickness by optical coherence tomography (OCT) were measured. Over 14 month follow-up period, baseline BCVA was 0.3 and it increased to 0.4 by the final examination, while macular thickness decreased from 264 μm to 229 μm. No side effects of PDT were noted. Conclusions: Verteporfin PDT for CNV-associated with angioid streaks does not appear to significantly alter the course of the disease undergoing enlargement and disciform transformation of the neovascular process. However, we expected that the actual clinical findings improved during short term follow-up. The severity of symptoms of CNV-associated with angioid streaks in a single patient varies over time, so long-term follow-up and careful examination is needed.

Purpose: To evaluate the early effect of orbital reconstruction with MacroPore® by assessment of orbital volume through orbital computed tomography (CT) in cases of orbital wall fracture Methods: We performed orbital reconstruction with MacroPore® in patients with orbital wall fracture smaller than 3 cm×2 cm. Orbital CT was done preoperatively and 6 months postoperatively. We then evaluated the results by measuring the orbital volume through Rapidia 2.8 program. Results: The study comprised 14 patients. The site of fracture was the medial wall in one patient, inferior in seven, and both medial and inferior in six patients. The site of insertion of MacroPore® was the medial wall in one patient, inferior in 12, and both medial and inferior walls in one. The mean volume of the affected orbit before operation was 20.23±2.78 cm3, that of the unaffected orbit was 18.27±2.24 cm3 (p- value=0.000), and the mean volume of the affected orbit after operation was 19.06±2.57 cm3, that of the unaffected orbit was 18.06±2.24 cm3 (p-value=0.000). The mean enophthalmos before operation was 1.00±0.62 mm, and after operation was 0.64±0.46 mm. The mean difference of orbital volume between the affected and the unaffected orbits before operation was 1.96±0.33 cm3, and 1.00±0.87 cm3 after operation (p-value=0.000). The mean volume of the affected orbit before operation was 20.23±2.77 cm3, and 19.06±2.57 cm3 after operation (p-value=0.000). Each cubic centimeter decrement in volume caused a 0.67±0.68 mm mean decrease of enophthalmos. Conclusions: We concluded that MacroPore® was safe orbital implant and effective in decreasing the orbital volume at early orbital reconstruction in cases of orbital wall fracture smaller than 3 cm×2 cm through a comparison of orbital volume before and after operation.

In China, the "regeneration of historic districts and the development of tourism" is being implemented as an important economic development strategy. However, as the resulting tourism gentrification has had a negative impact on local communities. Therefore, this study selects a typical historical district in China"s recent urban regeneration-Ouyuan historic district in Qingzhou City, Shandong Province. To sort out the development process of tourism gentrification, choose the factors affecting the regeneration of historic districts based on tourism, conduct a questionnaire survey with residents as the object, and use statistical analysis software(SPSS21) to analyze the impact of these factors on residents. This will contribute to future sustainable historic districts regeneration projects in other areas. The results show that the impact of tourism gentrification on the living environment of residents has an overall negative impact close to "general". The main impacts are concentrated on the physical environmental factors related to traffic such as "difficult parking", "inconvenient commuting", and "traffic jams and road congestion". It also includes "decrease of living facilities", "garbage problem" and "involuntary relocation due to rent increase". Through cluster analysis, we can see that there are three groups with different attitudes: negative opponents, positive supporters and indifferent neutrals. Except for a few residents who actively support, most residents show a passive and indifferent attitude towards tourism gentrification.

국제 무역 및 전세계 수산물 소비의 증가로 인해 다양한 수산물이 국내로 수입되어 유통되고 있다. 최근 수입수산물의 종명 및 원산지 표시사항을 허위로 기재하는 경우가 급증하여 식품안전성에 심각한 문제가 야기되고 있다. 불법적으로 유통되는 수산물의 안전관리를 위해 DNA 기반 기술을 이용한 종 판별법 마련이 시급하다. 본 연구에서는 전세계적으로 중요한 대형선망어업 어종 중 하나인 전갱이속 어류의 종을 판별하기 위해 duplex-PCR을 사용한 검출 방법을 개발하였다. 국내에 유통되는 T. japonicus과 T. novaezelandiae의 시료를 확보하여 COI 영역의 염기서열 분석을 통하여 종간 특이성을 나타내는 단일염기다형성 유전자를 탐색하였으며, PCR 증폭 산물의 크기를 고려하여 2개의 종 특이적인 정방향 primer를 설계하였다. Duplex-PCR 분석 결과, T. japonicus (103 bp), T. novaezelandiae (214 bp)와 같은 단일 밴드를 전기영동상에서 확인 할 수 있었으며 상호간의 비 특이적 밴드는 형성되지 않았다. 또한 duplex-PCR 방법을 통한 T. japonicus과 T. novaezelandiae에서 최저 0.01 ng/μl까지 검출됨을 확인 할 수 있었다. 따라서 본 연구에서 개발된 duplex-PCR 분석법을 이용한 전갱이속 어류의 종 판별법은 정확도와 민감도가 우수하여 수산물의 수출입 및 시중에 불법적으로 유통 가능성이 있는 제품을 신속하고 과학적으로 판별할 수 있어 수산물안전관리에 활용도가 매우 클 것으로 기대된다. Reliable labeling of fish products can reassure consumers regarding the identity and quality of seafoods. Therefore, techniques that can identify adulteration or mislabeling are valuable. To rapidly identify two Trachurus species, Trachurus japonicus and Trachurus novaezelandiae, a highly efficient, rapid, duplex polymerase chain reaction (PCR) having two species-specific primers simultaneously was identified. This species-specific primer focused on a single nucleotide mismatch in the 3’-terminal base of a primer designed in the mitochondrial cytochrome c oxidase (COI) subunit I DNA. To optimize the duplex PCR condition, gradient PCR reactions were conducted to determine the primer annealing temperature and the primer concentration. The PCR’s product was observed on the gel, suggesting that DNA molecules may be useful in differentiating the two species. The length of the amplification fragments were 103 bp for Trachurus japonicus and 214 bp for Trachurus novaezelandiae, which, along with the species-specific primer visualized by agarose gel electrophoresis, enabled accurate distinction of the species of the Trachurus genus. These results indicate that the duplex PCR, which has a species- specific primer based on single nucleotide polymorphism (SNP), can be useful for rapidly differentiating the two species of Trachurus. This duplex PCR analysis is simple, rapid, and reliable, and could be beneficial to protecting consumers’ rights.

박연정(Park, Yeon-Jeong) 대한검도학회 2021 대한검도학회지 Vol.32 No.1

이 연구의 목적은 한국 사회인 검도인구의 변화 추세를 분석하고 사회인 검도인의 검도수련 관련 요인을 분석하여 참여 검도인구의 활성화 방안을 위한 시사점을 모색하는 것이다. 연구수행을 위해서 제16회 한국사회인검도대회(2003년)부터 제31회 한국사회인검도대회(2018년)까지 검도대회 참가자 현황과, 연도별 인구변화 추이를 분석하였다. 또한 전국 공인검도장에서 검도를 수련 중인 사회인검도인 200명을 대상으로 검도수련과 관련된 요인에 대해서 통계분석을 실시했다. 연구결과, 2008년 제20회 한국사회인검도대회부터 청년부 검도인구의 유입이 줄면서 검도인구가 점차 고령화 되고 있다는 점을 확인할 수 있었다. 둘째, 검도 참여 인구 변화와 관련된 요인으로 비체계적인 지도 프로그램, 낮은 청결도, 지도자와 수련생 간의 부족한 심리적 유대감, 경제적 부담, 잦은 부상 등임을 확인할 수 있었다. 끝으로 이 연구의 한계와 함께 향후 관련 연구를 위한 제언을 논의하였다. The purpose of this study is to analyze the trend of change in the Korean social kumdo population and to find implications for the revitalization of the participating kumdo population by analyzing the factors related to the kumdo training of the members of society. For the purpose of the research, this study analyzed the current status of participants in the Kumdo Competition from the 16th Korean Social Kumdo Championship (2003) to the 31st Korean Social Kumdo Championship (2018) and the trend of population change by year. In addition, a statistical analysis was conducted on factors related to kumdo training for 200 socialites who were practicing kumdo at public kumdo institution nationwide. As a result of the study, it was confirmed that the kumdo population is gradually aging due to the decrease in the inflow of the youth group kumdo population since the 20th Korean Social Kumdo Championship in 2008. Second, it was confirmed that unsystematic guidance programs, low cleanliness, insufficient psychological bond between Kumdo master and trainees, economic burden, and frequent injuries were the factors related to the change in the population participating in kumdo. Finally, the limitations of this study and suggestions for future related studies were discussed.

박연정(Yeonjeong Park),Barbara Lockee,David Moor 호남대학교 인문사회과학연구소 2020 인문사회과학연구 Vol.63 No.4

본 연구의 목적은 외국인 대학원생의 이문화 의사소통 역량(Intercultural Communicative Competences: ICC)과 사회적으로 몰입된 학습 (Socially Engaged Learning: SEL)에 대한 인식을 조사하는 것이었다. 교수 설계의 내적 조건으로서 ICC는 외국에서 공부를 하는 대학원생들에게 요구되는 자질이다. 또한 교수설계 외적 조건으로서, SEL은 알려진 사회학습 이론에 대한 고찰과 핵심적 원리들을 도출하여 개념화하여 몰입학습을 사회적 측면으로 확장한 것이다. 미국 소재 한 대학에서 이루어진 사례 연구로서, 본 연구에서는 영어가 원어민이 아닌 중국, 인도, 한국 등 에서 온 대학원생 208명을 대상으로 ICC와 SEL에 대한 인식을 조사하였다. 정량 분석을 통해 대학내 다양한 문화적 배경과 학문적 배경, 사전 경험을 가진 외국인 유학생들은 비교적 양호한 수준으로 자신들의 이문화 소통 역량을 평가하였고, 사회적으로 몰입된 학습 전략에 대해서도 긍정적인 시각을 보였다. 각 역량과 교수설계 전략에 대한 인식의 세부 요인들에 대해서 통계적으로 유의미한 차이가 발견되어, 교수설계자가 이들 학생의 서로 다른 이문화 소통 역량을 이해하고, 이들이 보다 사회적으로 몰입된 학습 경험을 할 수 있도록 교수설계자가 문화적으로 보편적이면서 개별학생들의 문화적 특수성을 연결하는 교수 설계적 노력이 필요함을 시사하였다 The purpose of this study is to perceptions of international graduate students on intercultural communicative competence (ICC) and ID strategies for socially engaged learning (SEL). As an internal condition, ICC is a quality for those who enter a second language and culture. As an external condition, SEL includes recommended learning and instructional strategies for the students. SEL was derived from the review of existing and well-known social theories of learning. As a case study in a large university in the U.S., this study investigated perceptions on ICC and SEL with a sample of 208 non-native English speaking international graduate students coming from China, India, South Korea, and other diverse countries. Results of quantitative analysis showed that these students with different background characteristics, academic disciplines, cultural origins, and previous experiences perceived a moderately high level of ICC and generally had positive views on SEL strategies for socially engaged learning. Significantly different perceptions among sub-factors of ICC level and SEL framework across their backgrounds suggest that the instructional designers need to better understand students’ different intercultural competencies, to build a bridge in applying between generally-accepted versus culturally-specific instructional design principles, and finally to help students prepare their socially engaged learning successfully.

지각 활성화를 통해 본 현대 미니멀 건축의 특징에 관한 연구

박연정(Park, Yeon-Jeong),한지애(Han, Ji-Ae) 대한건축학회 2012 대한건축학회논문집 Vol.28 No.11

Minimalism, which appeared in artistic circle of 1960’s, has been tendency with time gap. Critic used the term of Minimalism so that express the present situation that the only formative characters of minimal art, simplicity and clearance, became known in the world. The minimal architecture came out in the social situation of minimal tendency and in the architectural situation that complicated and inscrutable form danced widely. Corporal perception is one among several tendencies that human, disregarded in architecture since 1960’s, became important. This is closely connected with phenomenology and found in minimal art. Activation of perception is the architect’s efforts for unsettled character. This is achieved through using features of corporal perception. Dialogic character can intensify through endless excitements. So minimal architects expose just as looks change or can show factors that is changing but non-physical through perceptual activation. The purpose of this study was to analyze the housing mobility behavior according to the income change and to predict the probability of upward and downward movements. A binary logit model was used with the data which were obtained by the Korea Research Institute for Human Settlements in 1989. The sample size was 1620 households in Seoul. The results of this study were as follows; the upward movement probability in rental housing or in single housing was higher than that in owned housing or in apartment housing as household income increased.
