Trade-employment linkage of FTAs in Korea: Inter- and intra-industry reallocations of production resources

장용준,조미진,김한성 한국무역학회 2018 Journal of Korea trade Vol.22 No.4

Purpose – The purpose of this paper is to empirically examine the link between trade liberalization and employment through the export channel under Korea’s FTAs by distinguish firm heterogeneity (i.e. size) as well as sector-level international competitiveness (i.e. comparative advantage). Design/methodology/approach – Using the firm-level data during 2000–2009, the authors drive the difference-in-difference-in-difference model on Wagner (2007) with the dependent variables of labor productivity and employments and the independent variables of free trade agreement, revealed comparative advantage, firm size and payroll costs. Findings – The authors find that the economic benefit of FTAs in Korea is not concentrated in large enterprises or firms with comparative advantage. Accordingly, the authors conclude that FTA or trade liberalization brings positive effects to business as a whole, rather than to specific industries or group of firms. Research limitations/implications – The Korean Government has continued its policy of supporting small and medium-sized enterprises (SMEs) for a long time by recognizing them as socially underprivileged. According to the results of this study, an increase in export through FTAs improves firm’s labor productivity and increases employment, especially for SMEs, which can be a practical and efficient support for them. Originality/value – The paper provides the empirical evidences that how the effects of trade liberalization on labor depend on firm heterogeneity, industrial competitiveness and/or both and thus how labor is reallocated in response to trade liberalization in Korea.

韓半島와 日本 九州地域의 後期 舊石器文化의 交流- 슴베찌르개(剝片尖頭器)를 中心으로 -

This paper discusses cultural exchange of tanged points(Sumbezzirugaes) for the Korean Late Paleolithic. After the tanged points(Sumbezzirugaes) were excavated in Whadae-ri, Jingeunul, Suyanggae, etc, it was found that this stone tools had been used in the Korean peninsula. In particular, tanged points were made by the blade techniques(crest and non-crest). It can be said that tanged point was developed by combining the local tool type and the flaking techniques from the external world. The types of points in the Korean peninsula had been continuously changed from the tanged points(Gorye-ri & Jingeunul) to the composited points & the narrow-bladed points(Suyanggae) and then to the composited points & the leaf-typed points(Shinbuk-ri, Seokchang-ri & Wolpyeong-ri). The layer that Contained Airatanzawa tephra(24ka) was unearthed tanged point in Kyushu. From this lithic tool, it is postulated that Korean Peninsula has cultural relations with the Kyushu of Japan in Upper Paleolithic. But blade technique of this area didn't use in crest technique for blade(blank of tanged point). The tanged points of Korea have co-existed with microblades. There are similarities and differences between the Upper Paleolithic of the Korea and that of Kyushu Island of the Japan. 한반도와 일본 九州지역에 공통적으로 존재하는 슴베찌르개는 당시 석기군의 양상으로 본다면 각 지역문화의 영역을 넘어선 접촉 또는 교류의 증거물이었다. 이 시기는 最大氷河 極盛期(LGM)에 해당하면서 해수면이 하강하여 陸橋까지는 아니지만, 구석기인의 이동이 가능할 정도로 두 지역이 가까웠던 시기였다. 이 때를 이용하여 한반도에서 처음 출현한 슴베찌르개가 일본으로 전해졌다. 일본출토 슴베찌르개(剝片尖頭器)는 여러 면에서 나이프형 석기와 서로 영향을 주고받았지만, 기본적인 박리기술과 석기 형식은 AT층 이전의 석기문화와는 전혀 다른 것이었다. 특히 석인 또는 종장박편을 활용하여 도구를 제작하는 개념의 전환은 이전의 석기군에서 유례를 찾기 힘들다. 슴베찌르개의 등장과 함께 九州지역은 10cm이상의 대형 수렵구를 제작할 수 있는 기술적 기반을 갖추게 되었고, 그 후 이 지역에는 角錐狀石器(추형찌르개)․槍先形 尖頭器를 비롯한 여러 수렵구가 출현하였다. 이런 사실은 슴베찌르개가 단지 하나의 석기형식에 지나지 않지만, 그 근저에 깔려있는 하위 문화적 속성을 같이 전달시켜줌으로써 九州지역의 수렵문화에 많은 변화를 불러 일으켰다는 점에서 큰 의의가 있다. 한편, 九州지역의 각추상석기의 원류가 한반도의 슴베찌르개에 있을 가능성이 높았다. 한국의 경우 슴베찌르개가 후기 구석기시대 후반의 세석인 단계까지 지속되는 반면, 일본출토 슴베찌르개는 단기간에 사용된 뒤 각추상석기로 변화하여 세석인단계 직전까지 사용되었다. 비록 한반도로부터 일본 구주지역으로의 대규모 이주증거는 찾을 수 없었지만, 기술적인 측면에서의 접촉 또는 교류가 있었음은 분명하였다.

무역기술장벽(TBT)의 한국 수출 효과: 수출시장과 품질 특성을 중심으로

장용준,현혜정 한국국제통상학회 2022 국제통상연구 Vol.27 No.4

This paper examines the impact of technical barriers to trade (TBT) on product-level export of Korea. We employ simple theoretical framework and empirical model using detailed dataset on nontariff measures for 129 countries at product level during the 1996-2019 period. Our empirical results show that TBT significantly reduces exports, particularly when exported products are destined to high income countries after the global financial crisis. On demand side, TBT promotes exports of high-quality products due to decrease in information asymmetry and increase in consumers’ trust, which highlights the demand-enhancing role of TBT through increases in product quality. 본 연구는 이론모형과 실증분석을 통해 1996년부터 2014년까지 129개 수입국이 취한 TBT 조치가 한국의 575개 품목별 수출에 미친 효과를 시기별, 수출시장별, 수출품 품질 특성별로 나누어 분석하였다. 분석 결과, TBT는 평균적으로 한국의 수출을 감소시키는 것으로 나타났다. 그러나 금융위기 이전에는 유의미한 효과가 없었으며, 수출장벽효과는 대부분 금융위기 이후 보호무역주의 기조가 높아진 시기에 더 현저히 나타났다. 국가별로, 소득수준이 높은 수입국 TBT의 부정적인 효과가 컸고, 소득수준이 낮으면 오히려 긍정적 효과가 나타났다. 수요 측면에서, 우리 수출품의 품질 수준이 높은 경우에는 TBT가 소비자에게 제품에 대한 정보의 비대칭 문제를 완화시키고 신뢰도를 높여 수요를 증대하는 역할을 함으로써 수출을 촉진시키는 효과가 있음이 나타났다. 이러한 분석결과는 TBT의 무역장벽 해소를 위해 수출품의 적극적인 품질개선과 기술혁신이 중요함을 시사한다.

탄력섬유종의 치험례

장용준,정철훈,조우성,김진왕,조성진 대한성형외과학회 2007 Archives of Plastic Surgery Vol.34 No.3

Purpose: Elastofibroma is a rare benign tumor that is characterized histologically by the presence of abnormal elastic fibers within a stroma of fibroadipose tissue. Usually it is slow-growing, solid, ill-defined mass occurring chiefly in elderly woman and arising from the soft tissue around the inferior angle of the scapula. Methods: We experienced a representative case of elastofibroma. A 73-year-old women complained of a soft-tissue mass, which measured 6×6cm, at the inferior angle of the left scapula, which had been found incidentally 4 months before. When the arm was elevated, the mass projected out beneath the scapula. The entire mass was resected with a tumor-free margin.Results: The resected tumor appeared to be nonencapsulated, fibrous and white mass, and it contained yellow fatty streaks. We confirmed that the histopathologic diagnosis of this tumor was elastofibroma. Follow- up examination revealed no evidence of local recurrence for 10 months.Conclusion: This entity is rarely reported in Korea. However, more patients could be diagnosed if physicians pay more careful attention to clinical and radiological features of elastofibroma. Moreover, recognizing the benign nature of this lesion is important to avoid an unnecessary operation.

Simple Correction of Alar Retraction by Conchal Cartilage Extension Grafts

장용준,김성민,유대현,송승용 대한성형외과학회 2016 Archives of Plastic Surgery Vol.43 No.6

Background Alar retraction is a challenging condition in rhinoplasty marked by exaggerated nostril exposure and awkwardness. Although various methods for correcting alar retraction have been introduced, none is without drawbacks. Herein, we report a simple procedure that is both effective and safe for correcting alar retraction using only conchal cartilage grafting. Methods Between August 2007 and August 2009, 18 patients underwent conchal cartilage extension grafting to correct alar retraction. Conchal cartilage extension grafts were fixed to the caudal margins of the lateral crura and covered with vestibular skin advancement flaps. Preoperative and postoperative photographs were reviewed and analyzed. Patient satisfaction was surveyed and categorized into 4 groups (very satisfied, satisfied, moderate, or unsatisfied). Results According to the survey, 8 patients were very satisfied, 9 were satisfied, and 1 considered the outcome moderate, resulting in satisfaction for most patients. The average distance from the alar rim to the long axis of the nostril was reduced by 1.4 mm (3.6 to 2.2 mm). There were no complications, except in 2 cases with palpable cartilage step-off that resolved without any aesthetic problems. Conclusions Conchal cartilage alar extension graft is a simple, effective method of correcting alar retraction that can be combined with aesthetic rhinoplasty conveniently, utilizing conchal cartilage, which is the most similar cartilage to alar cartilage, and requiring a lesser volume of cartilage harvest compared to previously devised methods. However, the current procedure lacks efficacy for severe alar retraction and a longer follow-up period may be required to substantiate the enduring efficacy of the current procedure.
