Intrapulmonary shunt was measured by $^{99m}Tc$-MAA perfusion tung scan. The study was included 76 patients. Significant amount of intrapulmonary shunt was observed in the pulmonary disease patients and liver disease patients. The shunt amount was correlated well with $PaO_2$ and $AaDO_2$ level. Further study is needed to search the various factors affecting the amount of intrapulmonary shunt.

This paper investigates how internal knowledge dependency and its interaction with external knowledge adoption affect innovation performance in Korean companies. We categorize innovation performance into exploratory innovation and exploitative innovation. Especially, we examine business group effects as group headquarters and sister subsidiaries holistically form the boundary of the firm. Our empirical results first suggest that the degree of internal knowledge dependency is positively associated with exploitative innovation, but negatively with exploratory innovation. Second, internal knowledge dependency is more negatively related to exploratory innovation in independent firms than in business group affiliates. Third, independent firms' adoption of external knowledge tends to strengthen the positive relationship between internal knowledge dependency and exploitative innovation. Finally, exploitative external knowledge search appears to strengthen the negative relationship between internal knowledge dependency and exploratory innovation in both types of firms.

The 2DBPP(Two-Dimensional Bin Packing Problem) is a problem of packing each item into a bin so that no two items overlap and the number of required bins is minimized under the set of rectangular items which may not be rotated and an unlimited number of identical .rectangular bins. The 2DBPP is strongly NP-hard and finds many practical applications in industry. In this paper we discuss a tabu search approach which includes tabu list, intensifying and diversification Strategies. The HNFDH(Hybrid Next Fit Decreasing Height) algorithm is used as an internal algorithm. We find that use of the proper parameter and function such as maximum number of tabu list and space utilization function yields a good solution in a reduced time. We present a tabu search algorithm and its performance through extensive computational experiments.

Purpose: The purpose of this study was to establish the foundations for the application of appropriate programs for pain reduction in patients with rheumatoid arthritis. Methods: The literature on patients with rheumatoid arthritis were found on an electronic search site for South Korean academic papers. The search terms "rheumatism" and "rheumatoid arthritis" were used independently. The combined terms "rheumatism and pain" and "rheumatoid arthritis and pain" were also used. For the meta-analysis, the R version 3.5.1 program was utilized. Results: The meta-analysis of eight papers showed a large effect size of -4.11. The programs were most effective in the order of aquatic exercise, aromatherapy, self-help education, muscle strength exercises, and tai chi. Conclusion: This study could provide the basis for presenting appropriate programs for pain management in patients with rheumatoid arthritis.

The goal of this article is to ascertain the factors that govern consumers' choosing to outbound travel product. The authors assess the consumers' travel product choosing processes with information search(internal knowledge, external information knowledge). alternative evaluation(perceived image, emotional experience, price acceptability, appeal, trust), and alternative choice(purchasing intention). Using data on Thailand travel product, the authors find considerable results and conclude by discussing prescriptive recommendations for the travel industry.

Objectives : The purpose of this study is to investigate the effect of laser therapy for diabetic ulcer by using methods of systematic review. Methods : In this review, PubMed, Cochrane library, Web of Science, CNKI, CiNii, J-STAGE, NDSL and OASIS were used as the search engines. The search period is from the start date of the search engine to October 3, 2016. Randomized controlled trials(RCTs) using laser therapy for diabetic ulcer were searched and extracted by two independent researchers. Risk of bias(RoB) of Cochrane was used to assess methodological quality of studies. Results : Finally, five RCTs were selected. The follow-up period ranged from 15 days to 20 weeks. InGaAlP laser, GaAlAs laser and light emitting diode(LED) were used to treat diabetic ulcer. The clinical trials used sham laser irradiation or standard treatment as control in comparison to laser therapy. The endpoints included ulcer size, rate of healing and time to healing with follow-up period. The RCTs demonstrated therapeutic outcomes with no adverse effect. Most items of RoB were unclear and methodological quality was low. Conclusions : Our analysis suggests that laser therapy has therapeutic effects for diabetic ulcer. However, more systematic and stringent clinical trials will be required.

Objective: The purpose of this study was to investigate the effect of electroacupuncture on acute pancreatitis (AP). Method: The search engines that were used included PubMed, CNKI, OASIS, NDSL, the Korean Traditional Knowledge Portal, and J-STAGE. The search period was from the creation of the search engine to May 6, 2019; there were no language limitations. Extractions and selections from the literation were made by two authors. The study included randomized controlled trials with electroacupuncture for patients with acute pancreatitis. Cochrane's risk of bias (RoB) was used as the methodological quality assessment scale. Results: Nine studies were finally selected. It was observed that using electroacupuncture with general Western medicine treatment for AP was more effective than using only general Western medicine treatment. Although most of the studies showed a high risk of bias, there were significant differences among the indicators. Conclusion: The electroacupuncture treatment with Western medicine may be more effective in reducing symptoms of AP than Western medicine alone. However, due to the limitations of the research design, it was not enough to obtain reliable information. As a result, high quality research will be additionally required.

관객은 이야기를 통해 허상의 세상과 현실의 세상을 넘나들게 된다. 이야기는 인간의 감각에 호소하는 감성적 체험이며 지식, 정보전달의 이성적 기능과 정서에 호소하는 감성적 기능이 있다. 또한 언어, 문자, 영상으로 그 형태가 나타난다. 본고는 이야기의 감성적 기능에 주목하며 체험된 이야기는 관객과 인물의 극적소통이 극대화되어 관객이 정서적 반응을 일으키는 것이다. 관객은 인물과의 심리적, 정신적 교감을 통해 어느 순간 감정몰입의 상태로 들어가고 이를 통해 동일시의 감정을 느낀다. 그때부터 관객과 인물의 극적소통이 시작된다. 하지만 그 순간을 지탱하는 힘은 그리 오래가지 못한다. 이런 관객몰입의 극적소통이 이루어지는 그 순간을 오래도록 지속시키기 위해서는 사실화작업을 거쳐야 한다. 이렇게 사실화작업으로 이루어진 세상과 그 속에서 살아가는 인물의 삶에서 관객은 공감적 재연의 체험적 관념을 흡수하게 되고 이런 사실화된 인물의 드러냄은 외적탐색과 내적탐색으로 가시화된다. 먼저 외적탐색에는 배경정보, 생활정보, 대화정보가 있다. 이들을 통해 인물은 인간과의 닮음의 진통을 극복하고 진정 관객과 소통하는 매개체로 재등장하게 된다. 또한 내적탐색의 세 가지는 자아, 욕구, 갈등이란 정신적 기제를 통해 선택적 단계선정의 연계과정을 겪으며 인물이 가지고 있는 내면의 울림을 밖으로 진동하게 하여 공명(울림)의 그 소리를 듣게 만든다. 여기서 중요한 사실은 감독은 인물이 가진 내면적 요인들을 행동으로 시각화시켜야 한다. 즉 행동에 의해 인간이 가지고 있는 외적, 내적 요소들이 서로 간의 충돌과 흡수를 통해 화면 위에 고스란히 그려놓아야 한다는 것이다. 그래야만 관객은 인물과의 극적소통을 통해 정서적 반응을 일으킬 수 있다. 영화 '시'에서 관객과 인물이 극적소통을 통한 정서적 반응을 일으키는 신을 중심으로 살펴보고 이를 통해 관객은 영화의 물리적인 상영시간 동안 인물과의 극적소통을 스스로 인내할 수 있다.
