전망이론 검증을 통한 부동산투자자들의 인지적 편의에 관한 연구

정성훈,박근우 한국부동산연구원 2017 부동산연구 Vol.27 No.1

In this study, we examine whether there are prospect theory investment patterns for individual investors in the real estate market. We use the maximum potential profit rate and the maximum potential loss rate of individual investors as a research method and additionally analyze it using the Jeong and Park(2015) model. As a result of the analysis, it was found that the investment pattern according to the prospect theory and disposition effect for individual investors. And we find the difference between zoning areas. This difference in investment behavior is believed to be due to the purpose of the real estate and the existence of rent fee, which creates a difference in investment behavior depending on the purpose. The limitations of this study are the analysis measurement of potential profit and potential loss using the land price index like the study of jeong and Park(2015). This implies that a new property price index needs to be developed or a benchmark for real estate assets is needed for deeper study of real estate investment sentiment. 본 연구는 부동산시장에서 개인투자자들에게 전망이론에 따른 투자패턴이 존재하는지 용도지역을 구분하여 검증하였다. 연구의 방법으로는 개인투자자들의 최대잠재이익률과 최대잠재손실률을 이용하였으며, 추가적으로 처분효과의 모형인 정성훈 박근우(2015) 모형을 이용하여 추가 분석을 실시하였다. 분석결과, 개인투자자들에게 전망이론에 따른 투자패턴과 처분효과가 존재하는 것으로 밝혀졌으며, 용도지역에 따른 차이가 나타났다. 개인투자자의 손실회피 성향이 주거용도 부동산자산 보다 상업용도의 부동산 자산에서 더 크게 나타났다. 투자행태에서 이러한 차이는 부동산의 목적과 임대료의 존재가 용도에 따른 투자행태의 차이를 만들어 내는 것으로 판단된다. 본 연구의 한계점으로는 정성훈 박근우(2015)의 연구와 같이 지가지수를 이용하여 미실현이익과 미실현손실을 분석하였다는 점이다. 이는 부동산투자심리에 대한 심도깊은 연구를 위해서는 새로운 부동산 가격지수에 대한 개발 또는 부동산자산에 대한 Benchmark가 필요하다는 것을 의미하며, 추후연구에서는 이를 발전시킬 필요가 있다.

부동산시장에서 투자자들의 투자행태와 심리에 관한 연구-처분효과에 대한 검증-

정성훈,박근우 한국부동산연구원 2015 부동산연구 Vol.25 No.3

The purpose of this study is to find the disposition effect in the housing market of Korea. Thorough the copy of a register book, we were able to get 1,752 data. In this study, we proposed the model to find the disposition effect which drew on models of Odean(1998) and Jeong SeongHoon(2003). In the result of this research, through the frequency model, we were able to find the disposition effect in the housing market. And we also found similarly result of Jeong SeongHoon(2011) which found the assets size effect. The suggestion point of this study is that we showed the behavioral biases of investors and the asset size effect who participate in real estate market of Korea. And given the paucity of material on the real trade data of Korea housing market, this study would be helpful to understand the behavior of investors. 본 연구는 부동산 시장 중 주택시장에서 투자자들에게 처분효과가 존재하는지 알아보기 위해 Odean(1998)과 정성훈(2003)의 연구모형을 부동산시장에 적합하게 응용하여 연구하였다. 본 연구의 데이터는 등기부등본을 통해 얻은 1,752개의 실거래데이터를 활용하였으며, 이를 통해 빈도기준에 따른 처분효과를 검증하고, 이익 및 손실금, 수익률에 대해 연구하였다. 또한, 이를 이용하여 주식시장에 나타난 자산규모효과와 투자자들에게 주요 변수로 작용할 수 있는 보유기간에 따른 처분효과를 추가적으로 검증하였다. 연구결과, 가설 1과 2를 채택하면서, 주택시장에서 부동산 투자자들의 처분효과와 자산 규모효과가 존재하는 것으로 나타났다. 금액기준을 통해 이익금과 손실금을 비교할 경우, 주식시장과는 달리 부동산시장에서는 지가지수대비 미실현이익금액(주식시장의 미실현이익금액)이 지가지수대비 미실현손실금액(주식시장의 미실현손실금액)보다 큰 것으로 나타났다. 이는 과거 지가의 지속적인 상승으로 인해 투자자들에게 낙관과 손실회피가 발생되어 이러한 현상이 나타난 것으로 판단된다. 본 연구를 통해 부동산시장의 투자자들에게는 인지행위적 오류가 있음을 밝힘으로써 학문적 시사점이 있고, 자산의 규모효과가 존재한다는 점을 밝힘으로써 실무적 시사점이 있다고 판단된다.

A Study on the Identification between Shipowner and Charterer to Sue for the Liability of transportation

정성훈 한국통상정보학회 2006 통상정보연구 Vol.8 No.4

In all cargo cases one of the first things the person handling the claim must do is decide who is potentially liable as a carrier of the goods. This issue arises because bills of lading often do not identify the carrier. The "carrier" could be the shipowner or the charterer or both. The issue of the identity of the "carrier" is a question of fact. The question to ask in each case is who undertook or agreed to carry and deliver the goods. The answer to this question will largely depend on the facts. The shipowner is almost always liable as a carrier under Common law provided there is no demise charter of the ship. The more recent case law, however, suggests that in the usual situation both the charterer and shipowner will be liable. Accordingly, both the owner and charterer should be put on notice of any claim and, in the event an extension of suit time is required, the extension should be obtained from both. An alternative method by which the charterer can avoid liability is to insert and 'Identity of Carrier' clause in the bill of lading.

『문장(文章)』의 번역 양상과 그 의미

정성훈 한국현대문학회 2024 한국현대문학연구 Vol.- No.72

이 글은 잡지 『문장(文章)』(1939~1941)에 수록된 번역 텍스트의 저본 및 번역 방식상의 특징을 밝힘으로써 연구사의 공백을 메꾸고, 당시의 검열장, 매체 환경, 담론 등을 고려할 때 이러한 번역 행위가 지니는 의미를 고찰함으로써 『문장』을 보다 풍부하게 읽고자 시도했다. 이를 통해 새롭게 밝힌 점은 다음과 같다. 첫째, 『문장』은 꾸준히 외국문학의 번역을 게재하였는데, 비록 작품이나 역자의 성격에서 큰 일관성을 찾기는 어려웠으나 그러한 비체계적인 번역 기획은 오히려 ‘조선문학이 추구해야 할 세계문학’이나 ‘교양으로서의 세계문학’이라는 관념으로 환원되지 않는 다양한 텍스트를 게재하는 효과를 낳았다. 둘째, 『문장』에 마련된 ‘전선문학선’이나 ‘SCRAPS’, 그리고 시국 관련 글들은 그 내용은 각기 다르지만 일관되게 동시기의 일본어 잡지 또는 단행본에서 실시간으로 번역해 온 것으로 추측된다. 그 중에서도 ‘전선문학선’은 다른 외국문학 번역과는 달리 작품의 극히 일부만이 초역(抄譯)되어 작품에 대한 종합적인 접근보다는 단편적인 묘사가 두드러지는데, 이는 당시 조선 비평계에서 일본의 전쟁문학을 ‘보고문학’으로 평가하는 관점과 궤를 같이하는 면이 있다. 셋째, 『문장』은 구미 작가들의 에세이나 여타 시국과 관련된 넓은 스펙트럼의 글들을 동시기 일본어 매체에서 실시간으로 번역해 왔다. 이때 일본어 잡지의 중역은 검열체제 하에서 정치적인 글들을 실으면서도 일본의 미디어에서 검증이 완료된 것을 번역함으로써 검열을 우회하려던 시도로 해석된다. 『문장』의 번역 텍스트는 번역 방식이나 내용 등에서 제각기 차이가 있으나 잡지의 지속적인 출간을 위해 불가결한 것이었다. 이를 통해 『문장』은 조선문학의 일반적인 창작 경향과 차이가 있는 다른 시공간의 문학을 보여주기도 했으며, 동시에 시국에 대한 글을 창작하기보다는 ‘번역’하는 방식을 취함으로써 중일전쟁과 신체제, 세계대전이라는 정치적 영역으로부터 거리감을 확보하는 효과를 낳기도 했다. 이러한 번역 행위는 잡지라는 매체의 운영 과정에서 지속적으로 이루어진바, 이와 같이 『문장』 번역의 특징을 살피는 것은 『문장』의 매체 전략이나 정치성을 재고할 여지를 마련할 뿐 아니라 ‘식민지’ 조선의 잡지매체에서 ‘번역’이 지닐 수 있었던 잠재적인 효과를 생각하는 데도 시사점을 제공할 것이다. This paper aims to investigate the original texts translated in Munjang(1939~1941), search for characteristics of the their translation, and consider the implications of these translation practices in light of the censorship, the media environment, and discourse of the time. The following findings emerged from this study. First, Munjang consistently published translations of foreign literature, and while it was difficult to find consistency in the works or the translators, the inconsistent planning of translations provided an opportunity to publish a variety of texts that were not absorbed into the concept of ‘world literature that Korean literature should pursue’ or ‘world literature as liberal arts’. Second, texts like ‘War Literature,’ ‘SCRAPS,’ and the current affairs in Munjang are presumed to have been translated from Japanese magazines or books in real-time, despite their differences in contents. Especially, ‘War Literature,’ unlike other translations of foreign literature, translated only a small part of the original work, thus standing out for its fragmentary description rather than a comprehensive approach to the original work, which is in line with the view of Japanese war literature as ‘reportage literature’ in Korean critiques at the time. Third, Munjang retranslated essays by Western writers and other texts dealing with political issues, already published by contemporaneous Japanese media in real-time. In particular, this retranslation of Japanese magazines can be interpreted as an attempt to bypass censorship by publishing political texts that had been ‘verified’ from Japanese media. The translated texts of Munjang, while differing in style and content, were indispensable for the continuous publication of the magazine. As a result, Munjang could present ‘literature’ from another time and space that differed from the usual works, and at the same time, by ‘translating’ rather than creating texts about political issues, could achieve the effect of distancing itself from political commitment related to the Sino-Japanese War, the new system, and the World War Ⅱ. Since these translation practices were a continuous process in the publication of the magazine, studying the translation in Munjang not only provides chance to reconsider the media strategy or political nature of Munjang, but also provides important implications for understanding the effects of “translation” in the magazine medium in colonial Korea.

임파워링 리더십의 권한과 책임에 따른 양면적 효과

정성훈,하성욱 한국인적자원개발학회 2023 인적자원개발연구 Vol.26 No.4

This study empirically examined the two faces of empowering leadership, i.e. the enabling process and the burdening process, when empowering leadership is decomposed into authority delegation and accountability with the sample of 219 followers in private companies. The enabling process, which means that the leader’s empowering leadership enhances the follower’s work role performance through increasing the follower’s self-efficacy, is empirically demonstrated when the empowering leadership is authority delegation and accountability respectively. The burdening process, which means that the leader’s empowering leadership undermines the follower’s work role performance through increasing the follower’s job induced tension, is not empirically demonstrated when the empowering leadership is authority delegation and accountability respectively. The follower’s job induced tension increases the follower’s work role performance unexpectedly. Furthermore, the follower’s job induced tension has an inverted U-shaped relationship with the follower’s task proactivity, which is a dimension of work role performance. The leader’s authority delegation of empowering leadership decreases the follower’s job induced tension unexpectedly. The leader’s accountability of empowering leadership increases the follower’s job induced tension more than the leader’s authority delegation of empowering leadership does. Based on the results, theoretical and practical implications are discussed, and recommendations for future research are provided.

This study analyzed relation with risk recognition degree by customs business of customs brokers and actuality insurance accident occurrence.These study finding that risk recognition by customs work area of customs brokers and actuality insurance accident occur did not agree.So customs brokers more elevate risk recognition of entry field, origin/trademark right, HS and customs tariff application, customs refund, price estimation that are high the insurance accident rate. and they may have to do emphasis administration through employee education and ability elevation.Specially, operation risk that is produced from charge employee's simplicity mistake who tax invoice omission, a tax use mistake, document nondelivery, notice dispatch delayed action, may have to manage through moral management and employee bylaws and education, employee guidance etc.Also, they publicize these contents to import and export enterprise, and practice risk management of high risk business in priority through education and public information. so we will have to make can do more effective risk management.

Effect of Cr on the Hot Ductility of Austenitic Fe-Mn-Al-C Lightweight Steel

정성훈,문준오,박성준,이창희 대한용접접합학회 2024 대한용접·접합학회지 Vol.42 No.2

In this study, a hot ductility test was performed for Fe-30Mn-10.5Al-0.9C-Cr austenitic lightweight steels. The test was carried out through a commercial Gleeble simulator at a heating rate of 350 °C/sec and cooling rate of 50 °C/sec, with a stroke rate of 50 mm/sec. Microstructural analysis for understanding the hot ductility behavior was conducted through optical and scanning electron microscopy. The lightweight steels exhibited similar hot ductility behavior in accordance with temperature despite the addition of Cr. The experimental results indicated that the κ- carbide precipitation had an insignificant influence on the hot ductility test. However, ductility at low temperature was induced by slip mechanism, while dynamic recrystallization had significant influence at high temperatures during the on-heating thermal cycle. In the on-cooling thermal cycle, the melted and re-solidified grain boundaries decreased the overall ductility, exhibiting the same tendency as that observed in the on-heating test.
