Local Identity and Persistent Leadership in Market Share Dynamics: Evidence from Deregulation in the Korean Soju Industry

최재필,홍승현,전성훈 한국경제학회 2013 The Korean Economic Review Vol.29 No.2

This paper documents persistence in brand preferences and investigates its sources. We examine the Korean soju industry, in which the government designated only one firm for each regional market and obliged consumers to purchase local brands. We find that consumers tend to purchase local brands even after this regulation was removed. To explain the persistent leadership of local firms in their respective markets, we propose an identitybased theory with three theoretical implications. In particular, we consider regionalism in Korean politics, and use presidential election results as events that triggered higher identity costs, thereby increasing local market shares of designated local companies. We find empirical evidence consistent with three theoretical implications, which is robust to several alternative specifications. We further find that various other mechanisms are not fully consistent with our data, suggesting that local identity, once established, can be an important source behind persistence in preferences for local brands.

항레트로바이러스제 치료의 확립, 조기치료로 HIV 감염인들의 바이러스의 조절과 면역저하의 개선이 이루어지고 있다. 다수의 환자들이 더 이상 에이즈 관련 합병증으로 사망하지 않고, 심혈관질환, 대사성질환, 간질환, 신장질환, 신경계질환과 같은 만성합병질환을 갖고 고령화되고 있다. 그러나 지금도 여전히 사회적 차별과 낙인이 존재하는 가운데 후기 발현자로 후천면역결핍증 상태로 방문하여 사망하거나 중증의 신경계합병증으로 장애를 갖는 환자들이 있다. 환자의 다양한 증상들에 대해 이른 시기부터의 완화의료적 접근이 필요하다. 원위 대칭성 감각 다발신경병증 등의 환자의 만성 통증은 저평가되어 왔고 이에 대한 적극적인 통증 중재가 필요하다. 이전 호스피스 기준은 현재 시점에서 새롭게 제시한다. 감염인의 약제 지속 등의 의학적 필요, 심리적 상태, 사회적 여건에 대한 이해가 필요하다. 표준주의 감염관리 원칙을 준수한다면 만성질환으로서의 보편적 호스피스 진료의 제공이 가능하겠다. 생의 말기 빠르고 적극적인 호스피스팀의 개입을 통해 환자들이 존엄하게 삶을 마무리하실 수 있도록 임상경험이 늘어나고, 제도가 마련되길 바란다. According to the advance of antiretroviral regimen and the early treatment strategy, people living with human immunodeficiency virus (PLWH) are achieving the goal of virologic suppression and immune restoration. Most of them no more die of acquired immunodeficiency syndrome (AIDS) defining illnesses, and become older with chronic comorbidities such as cardiovascular, metabolic, hepatic, renal and neurological diseases. However some PLWH still visit hospitals as late presenters with very low CD4+ T cell counts, so that they suffer AIDS defining illnesses to die or experience severe neurological complications resulting in disabilities. Early palliative interventions are needed on the various symptoms of PLWH. Thus far chronic pains such as distal symmetric sensory polyneuropathies have been underevaluated. Active pain-relieving interventions are important to them. Recently we define end of life condition of human immunodeficiency virus (HIV) or eligibility to hospice care after adjusting current status of HIV treatment. Hospice teams should pay attention to the specific medical conditions, psychological needs, and social circumstances of PLWH. With just standard precautions as common infection control measures, general hospice cares can be provided to them like to other hospices subjects. For giving PLWH opportunities to have the end of life with value and dignity, hospice multidisciplinary team should intervene them early and aggressively. Now we need more clinical experiences and institutional improvements.

FRAND Royalties and Injunctions for Standard Essential Patents

최재필 연세대학교 동서문제연구원 2016 Global economic review Vol.45 No.3

I develop a stylized model of court procedures that resolve disputes concerning FRAND-encumbered standard essential patents (SEPs). I analyze the effects of injunctions and potential court-imposed FRAND rates on negotiated royalty rates. The SEP holders’ ability to hold-up is constrained by the prospect of the court-imposed license terms in case of disputes, but is not completely eliminated. Possible mechanisms to address the residual hold-up power of the SEP holders are discussed.

아파트 단위평면확장 리모델링 기법에 관한 연구

최재필,강효정,이윤재,이정원,문준식,Choi, Jae-Pil,Kang, Hyo-Jeong,Lee, Yoon-Jae,Lee, Jung-Won,Moon, Jun-Sik 한국주거학회 2010 한국주거학회 논문집 Vol.21 No.3

Apartments have been the most prevalent type of housing in Korea for the past few decades. During those times, apartments have emerged as one of the most attractive real estate properties in Korea, with the still growing population living in them. Now that over twenty years have passed since the 1970s and 1980s when apartment construction started booming, building stocks are increasing that need refurbishment. In this concern, apartment extension has raised public interest for the past few years, as the remodeling of them has mainly been considered in terms of increasing asset value in Korea. It comes through in our study that these extension types are examined by such items as building core types, number of rooms and front and rear bays in unit, and other design features related to extension techniques. The objective of this study is to suggest a way to produce the best quality possible of unit plan through extension.

카자흐스탄 아파트 단위세대 평면변경 사례를 통해 살펴본 주거요구의 경향

최재필,이재훈,손동화,김영우,Choi, Jae-Pil,Lee, Jae-Hoon,Shon, Dong-Hwa,Kim, Young-Woo 한국주거학회 2014 한국주거학회 논문집 Vol.25 No.1

As an emerging market in central Asia, Kazakhstan's housing market is witnessing increasing demands. Though Korean construction industries have attempted to take advantage of this opportunity, inadequate understanding of the local living demands have kept the industries from successfully establishing themselves in the foreign context. The goal of this research is to derive architectural planning implications regarding the living demands by investigating changes being made to the housing structure. By analyzing 11 apartment unit plans, it was found that Kazakhs had a living demand for more spacious living rooms and functional spaces. In the effort to improve the livingroom environment and usability such as enlarging the livingroom, removing the living room wall for open space or expanding the inner space facing outside is understood that the living room is considered as an important space. The fact that spaces such as dress rooms and utility rooms are being added in the housing market, reflects the demand of functional spaces. These demands are considered as the reflection of the traditional life style of nomad culture and the cold local climate. Therefore, it can be said that the apartment unit plans distributed in the Korean housing market are quite compatible with the Kazakh housing market since they offer spatious living rooms, while the latter founding implies the changes that ought to be made for a successful establishment in the foreign market.

한국스타일 아파트 단지 외부공간 계획의 기초연구

With the IMF crisis in the late 1990's, coupled with the excessive supply of housing stock from the past, construction companies are adopting various differentiating strategies to address the decreasing apartment sales rates. Most of those strategies tend to follow the recent trend of 'eco-friendliness,' creating images of the apartments as 'well-being housing types.' In doing so, green spaces and water features are actively being used in outdoor landscapes design. One specific trend that can be witnessed is the efforts to make reference to the traditional Korean design languages, known as the 'Korean Style.' However, the applications of the 'Korea Style' on landscape design are being explored only by the construction companies, while most researches on the 'Korean Style' focus on its application on the indoor housing units. In this context, this series of case studies of the application of 'Korea Style' on landscape design attempts to extract design elements that can be set as basic guidelines.

사회통합 구현을 위한 유휴 공공시설 활용 방안에 관한 연구 - 유휴 동사무소 및 유휴 학교시설에 대한 '사회통합적 복합시설'로의 재활용을 중심으로 -

Due to the growing interest in eco-friendly and sustainable design in the architectural and urban planning field, we are witnessing numerous projects in which old buildings are being reused. However, with the exception of domestic apartments, there hasn't been a systematic approach or policy regarding the reuse of specific building types. On the other hand, we were able to point out two public building types, dong-offices and primary schools, that are expected to be underused, with future needs for conversion. Because the two building types are public buildings, we believe that their conversion must address the needs of the society. In this study, we have chosen 'social integration' as the ultimate goal of reusing public buildings. Upon the conceptual model of 'Housing-Mixed Public Facility', which was produced in a previous study, we have added other core programs that could be adopted into the model. Then, we applied the improved model onto the two building types by producing conversion plans and introducing key planning techniques. During this process, we have found some regulations that would not allow the realization of some models. Therefore, we have suggested amendments to the related regulations.

Analysis on the Causes and Characteristics of Child Loss through Surveys

최재필,최소영,유세원,한규빈 대한건축학회 2022 Architectural research Vol.24 No.3

Since lost child occurs frequently around us and there is a possibility of leading to an accident or a crime subsequently, it is necessary to study and have a plan for preventing child loss in advance. However, the preceding studies do not systemize the causes of child loss by places or situations, and the policy focuses only on the countermeasures afterward instead of prevention. In such perspective, this study derived the causes of child loss through the analysis of 202 cases by the bottom-up method. In addition, the causes were analyzed by dividing them into as negligence of guardian, breakaway of child, and environmental characteristics. As a result, it is found that children get lost by complex reasons usually with two or three causes combined together. And children got lost when guardians were not able to pay attention to their children, or when children moved away from their guardians. Furthermore, the environmental characteristics act as the catalyst by arousing child loss or making it more difficult for guardian to find the lost child. As a fundamental research, this study may be helpful in developing a environmental design certification system for preventing child loss in advance.
