RJV 참여기업의 기회주의 가능성과 해

김정홍 한국국제경제학회 1997 국제경제연구 Vol.3 No.3

본 연구에서는 RJV참여기업의 이탈 내지는 상대기업을 속이는 경우 RJV가 성립될 수 있는지 또는 속이는 기업과 속는 기업간에 어떤 성과를 얻을 수 있는지를 단계별로 분석하였다. 즉 RJV結成段階(제IV절), RJV결성후 이로부터의 산출물이 나오기 이전 단계(제III절) 등 두 단계로 나누어 게임이론으로 분석하였다. 이러한 분석을 토대로 하여 본 논문에서는 RJV참여기업에 내재된 속임수의 인센티브를 줄일 수 있는 방안이 무엇인지 강구해 보고자 하였다. 分析結果 Veugelers and Kesteloot모형에서의 결론처럼 RJV 내에서의 속임수에 대한 대응이 항상 정직만이 최선은 아니며, 경우에 따라서는 속임수도 최선일 수 있다는 것을 제시하였다. 이와 아울러 속임수에 대한 해결책으로 계약후 기회주의에 대한 위약금 부과, RJV내의 선도기업에 대한 라이센스권 부여, 시장신호를 이용한 심사제도의 활용 등을 제시하였다.

고용·임금에 의한 지역 유형화 및 선순환 가능성 분석

김정홍 한국은행 2017 經濟分析 Vol.23 No.4

In this paper, I analyzed the virtuous cycle regarding employment, production and wages at the regional manufacturing level. For this study, 233 primary local regions were classified according to their employment and wage levels, falling into 4 categories. There were 90 regions with high employment and high wage, 26 regions with low employment and high wages, 27 regions with high employment and low wages, and 90 regions with low employment and low wages. Following classification, the correlation between employment and wages was analyzed, and the resulting correlation coefficient was 0.436 a little high. The correlation graph between employment and wages in the 233 primary local regions goes up and to the right, the symmetric pattern of a Phillips Curve. The result of the Granger Causality Test suggests that employment increases production, production increases wages, and wages increase employment. Finally, an analysis was conducted on the possibility of the virtuous cycle of employment, production and wages in the primary local regions. Three linear regression and simultaneous models fit well and each independent variable, including employment, production and wages had significantly positive signs. So, if employment increases on the local level through regional industrial policy, regional production and wages will also increase sequentially. In conclusion, the virtuous cycle in action in regional industry is clearly observable. 기초지자체의 제조업 통계를 이용하여 고용과 임금 수준을 지역별로 유형화한 결과, 고고용-고임금 지역 90개, 저고용-저임금 지역 90개, 저고용-고임금 지역 26개, 고고용-저임금 지역 27개로 분류되었다. 또한 종사자 1인당 급여액으로 파악한 임금수준은 사업체당 종사자 수로 파악한 고용과도 비교적 양호한 상관관계를 보였다. 각 기초지자체의 고용과 임금을 하나의 데이터 쌍으로 하여 도시한 결과, Phillips곡선과 대칭 형태로 우상향의 추세를 보였다. 마지막으로, 지역산업 데이터를 이용하여 고용-생산-임금의 선순환 가능성을 추정 결과, 각 변수 간에 유의적인 플러스의 영향을 주는 것으로 분석되었다. 이에 따라 창업지원이나 기업유치 등과 같은 지역산업정책 수단에 의해 지역 내 고용이 증가될 경우 지역산업 내에서의 선순환이 잘 작동될 것으로 예상된다.

Purpose: A plunging ranula is relatively uncommon and represents a mucus escape reaction occurring from a disruption of the sublingual salivary gland. It is a common condition found in young adults, even though the reported age range is 2 - 61 years. We report our experience of a complete excision of a plunging ranula via the intraoral and submandibular approach. Methods: A 23-year-old man had a large protruding mass in the right submandibular area. Initially,the protruding mass appeared bilaterally but the left side disappeared spontaneously. The MRI findings revealed a homogenous fluid attenuation mass in the submandibular space, suggesting a ranula. The sublingual gland was extirpated through the intraoral approach and the ranula excised totally via the submandibular approach. Results: The patient had an uneventful postoperative course without infection, paralysis and tongue sensory changes, etc. The pathology findings were characteristic of a pseudocyst without a lining epithelium or endothelium but with a vascular fibro-conective tissue wall filled with mucinous fluid. No recurrence was observed on the submandibular area during the 8 month follow-up period. Conclusion: The combined intraoral approach and submandibular approach is an effective and highly recommended method for sublingual gland extirpation and complete excision of a plunging ranula.

Mucin secretion in the airway epithelium acts as an essential barrier process that protects the upper respiratory tract from inhaled particles, environmental pathogens and toxicants. However, dysregulated mucin secretion contributes to pathophysiologic conditions such as rhinitis, asthma, and chronic obstructive pulmonary disease etc. The study on mucin hypersecretion has long been worked, but the exact molecular composition and mechanism for exocytic machinery remain mostly to be elucidated. The regulated mucin secretion, highly coordinated process, is mediated by the cooperative interaction of several proteins existing in the secretory granule, cytoplasm, and plasma membrane. This review provides the information on molecular components of the core exocytic machinery and their functional roles for mucin exocytosis in airway secretory cells.

사람 구강암종 세포주에서 Interleukin-4에 의해 유도된15-Lipoxygenase-1을 매개로 한 세포고사 작용

Background and Objectives:In oral cavity cancer (OCC) cells, the effects of interleukin-4 (IL-4) are various according to the cell specificity. However, if IL-4 induces apoptosis on OCC cells, the mediator of this apoptosis is uncertain. Therefore, we investigated whether apoptosis of OCC cells occurs by IL-4 and whether 15-lipoxygenase-1 (15-LO-1) induced by IL-4 is the possible mediator of this apoptosis. Materials and Methods:SCC 1483 cells were used. Flow cytometry and poly ADP-ribose polymerase cleavage were used to examine apoptosis. Western blot analysis and reverse transcription-polymerase chain reaction were used to measure 15-LO-1 protein and mRNA. Results:The inhibition of cell proliferation by more than 50% was noted from 10 ng/ml of IL-4. At this dose, apoptosis was observed and this apoptosis was inhibited by 2.2 μM caffeic acid. 15-LO-1 expression was observed from the 8 hour treatment of IL-4 and apoptosis increased after the 24 hour treatment of IL-4. In this apoptosis, caspase cascade, cyclooxygenase-2, and non-steroidal anti-inflammatory drugs-activated gene-1 (NAG-1) were not involved. Conclusion:IL-4 induced apoptosis in SCC 1483 OCC cells and 15-LO-1 induced by IL-4 may mediate this apoptotic pathway.

Botulinum Toxin Type A (BOTOX$^{\circledR}$)를 이용한 성대 육아종의 치료효과

김정홍,김한수,남지인,장정현,김지훈,최홍식 대한후두음성언어의학회 2003 대한후두음성언어의학회지 Vol.14 No.1

Background and Objectives : The vocal fold granuloma has been associated with vocal abuse, gastroesophageal reflux, endotracheal intubation and habitual throat clearing etc.. Granuloma is benign growth of hypertrophic granulation tissue. It is usually located on the posterior third of vocal fold, in one or both vocal process of the arytenoid cartilage In spite of the voice therapy, steroid therapy, anti-reflex therapy and surgical procedure. The distinct advantage and uniform success rate of each methods have not been generally shown. Authors report that localized injection of botulinum toxin type A (BOTOX$^{\circledR}$) is the promising method both as an initial treatment and as an alternative treatment in patients who do not respond to standard therapy or who are poor surgical candidates. Materials and Method : We carried out a retrospective study of 9 patients with the diagnosis of vocal fold granuloma on the videostroboscopic examination from Jan 2000 to Mar 2003. The botulinum toxin type A was injected into one or both thyroarytenoid muscle or lateral cricoarytenoid muscle under the electromyography. The average dosage ranges from 6U to 8U per injection. Results : Unilateral vocal fold granuloma in 7 patients had been resolved completely within 2-3 months after first injection : 5 patients received th\ulcorner GER medical therapy in addition to the Botulinum toxin injections, 2 patients was resolved completely who had shown recurrence after $CO_2$ laser vaporization. 2 patients who had shown recurrence after $1^st$ injection were also completely resolved within 6 months after further injections. Conclusion : We expect that localized injection of Botulinum toxin type A can provide an alternative treatment for the refractory cases to the traditional forms of therapy and avoid the recurrence in conjunction with proper medical and voice therapy against GER and vocal abuse.
