Purpose: The characteristics of hypoparathyroidism in patients with Hashimoto thyroiditis (HT) after total thyroidectomy are not well established. The aim of this study was to investigate the relationship between hypoparathyroidism and loss of parathyroid glands in patients with or without HT who underwent total thyroidectomy. Methods: Patients who underwent total thyroidectomy were divided into two groups; with HT (n=166) and without HT (n=526). Clinicopathologic characteristics were compared between the two groups. Results: The mean numbers of parathyroid glands in specimens were significantly smaller in the with HT group than in the without HT group (0.34±0.51 vs. 0.42±0.58, P=0.003). The rate of transient hypoparathyroidism was significantly higher in the with HT group than in the without HT group (51.8% vs. 34.6%, P=0.000). Serum total calcium levels in patients who experienced transient hypoparathyroidism did not differ significantly between groups (P=0.335). The incidence of transient hypoparathyroidism of patients who preserved all four parathyroid glands or sacrificed one parathyroid gland was higher in the with HT group than in the without HT group, although that of patients who sacrificed two or more parathyroid glands was similar between groups. The incidence of permanent hypoparathyroidism in the two groups did not differ (P=0.546). Conclusion: Patients with HT had a higher rate of transient hypoparathyroidism after total thyroidectomy, particularly patients who preserved all four or three parathyroid glands. It is likely that the blood supply to the parathyroid gland might be vulnerable in patients with HT. Therefore, even though all parathyroid glands were preserved, careful monitoring of hypoparathyroidism is necessary after total thyroidectomy in patients with HT.

과실범처벌의 현대적 과제 -기업범죄와 관련하여-

최근 우리나라에서는 서해위도페리호침몰사고·성수대교붕괴사고·대구지하철공사장가스폭발사고·삼풍백화점붕괴사고·괌KAL기추락사고 등으로 수많은 사람이 사망하였고, 또한 이른바 ‘안전불감증’이 원인이 된 씨랜드청소년수련원화재·대구지하철참사·경주마우나리조트붕괴사고·세월호침몰사고·판교테크노밸리축제환풍구붕괴사고 등 대형 사고들이 속출하였다. 현대산업사회에서 과실범의 전통적 개념은 정당성이라는 측면에서 뿐만 아니라 형벌의 일반예방효과라는 측면에서도 불충분하다고 할 수 있다. 형벌의 예방효과는 행위자가 자신의 부주의하고 위험스러운 행위가 운 좋은 탈출구가 있어 처벌되지 않을 수 있다는 희망을 가질 수 있을 경우에 약화될 수밖에 없다. 따라서 과실범처벌의 과제는 이러한 처벌의 효과에 대한 의문과 사회나 유족의 처벌 요청을 어떻게 조정하고 과실범의 처벌을 적정하게 그리고 효과적으로 실현하느냐에 있다. 형법상 과실범이 성립하기 위해서는 기본적으로 주의의무위반, 법익침해적 결과의 발생, 결과와 주의의무위반과의 인과관계 또는 객관적 귀속 등이 충족되어야 한다. 그러나 과실범에서의 과실의 개념으로서 주의의무위반의 내용이나 그 체계적 지위에 대하여는 여전히 의견의 일치를 보지 못하고 있을 뿐만 아니라, 특히 과실에 대한 판단요소로서의 예견가능성과 회피가능성의 체계적 지위에 대해서는 객관적 귀속과의 관련성을 비롯한 이론의 체계적 논란이 분분한 상황이다. 위험사회라는 시대적 상황과 위험형법의 필요성과 같은 정책적인 측면에만 귀 기울인다면 형법의 본래 의의와 취지가 무너져 내릴지도 모른다. 그럼에도 불구하고 현대산업사회에서 기업이 경영활동 과정에서 법익침해의 위험이 큰 대형 사고를 일으켰을 때에는 기업경영활동에 대한 객관적인 부주의, 즉 과실이 인정되어야 한다는 것이다. Recently, it is the subject of intense interest in criminal law that human and physical damages, caused by various disasters in modern industrial society, have more decisive and direct effect on the life and property of the people than a individual crime has effect on those. If you look at the substance of life and property damages caused by the accident that occurred in the course of corporate management activities, there is a considerable number of causes of the damage occurred in management of companies rather than the employee is a direct actor who induced the accident. That is, since the management of the company does not fulfill the management oversight responsibility for the employee, those results have not a few occurred. For social infringement appeared in the course of the business of management activities as a social problem, it is not easy to advance a reasonable theory, namley a criminal oversight responsibility to the business owner. on the doctrine of traditional professional negligence. Therefore, in the new regulatory approach to social infringement shown in the course of business activities of the company, at the request of social demands that business owners must undertake the higher professional negligence liability, I want to raise the issue of management supervision negligence of issues have been raised in a type of professional negligence. In conclusion, more people are becoming aware of social conflict because of various mass incidents in modern industrial society. The supervisory responsibility takes the form of multiple negligence offenses. When it is accepted to substantially realize the dangerousness in the act of original directors, the proximate causal relation is observed regardless of whether the intervention of the supervisor``s mistake for the result occurrence.

트랜스임피던스 증폭기는 전체 광 수신기의 성능을 결정하는 가장 핵심적인 블록으로써 높은 트랜스임피던스 이득과 기가 비트급의 넓은 대역폭을 요구한다. 본 논문에서는 아날로그 어댑티브 이퀄라이저를 이용하여 트랜스임피던스 증폭기의 대역폭을 보상하고, 리미팅 증폭기를 이용하여 전체 트랜스임피던스 이득을 증가 시키는 단일 칩 광 수신기의 아날로그 회로를 제안한다. 0.13㎛ CMOS 공정을 이용하여 설계한 광 수신기는 포스트 레이아웃 시뮬레이션 결과, 120㏈Ω의 트랜스임피던스 이득과 5.88㎓의 대역폭을 갖는다. 수동 인덕터 소자를 사용하는 대신 네거티브 임피던스 컨버터 회로를 적용함으로써 0.088㎟의 매우 작은 칩 사이즈를 갖는다. Transimpedance amplifier(TIA) is the most significant element to determine the performance of the optical receiver, and thus the TIA must satisfy the design requirements of high gain and wide bandwidth. In this paper, we propose a novel single chip optical receiver that exploits an analog adaptive equalizer and a limiting amplifier to enhance the gain and bandwidth performance, respectively. The proposed optical receiver is designed by using a 0.13㎛ CMOS process and its post-layout simulations show 120㏈Ω transimpedance gain and 5.88㎓ bandwidth. The chip core occupies the area of 0.088㎟, due to utilizing the negative impedance converter circuit rather than using on-chip passive inductors.

Power plant engineering industry obtains EPC plan project and delivers results about electricity, measurement, machinery, and piping and so on. Its works are taken by projects. Although power plant engineering composes 2~5% of whole EPC project cost, it's one of the fundamentals because it affects process after planning step a lot. However, domestic power plant engineering companies' project performance ability is insufficient and there's a need for systematic performance. Thus, this study defined related factors of successful performance and analyzed the priority among them through analytical hierarchy process. All respondents recognized experience, knowledge, and communication as important factors. Administrators considered knowledge, experience, and communication. But hands-on workers considered experience, knowledge, human resources. Those who have experience in oversea project considered process, experience, human resources. However those who don't have experience in oversea project considered knowledge, experience, and communication. Recognition of important factors varies by the position and work experience of members.

대표적인 글로벌 혁신기업인 디자인회사 IDEO의 CEO 팀브라운은 “고객을 대상으로 정보를 쏟아내는 웹 1.0 시대와는 달리, 고객이 적극적으로 참여하는 웹 2.0시대의 도래로 인하여 더 이상 고객을 수동적인 존재로만 대할 수 없다”라고 주장하였다. 이렇듯, 고객이 기업의 제품개발에 적극적으로 참여하여 가치를 극대화하는 공동가치창출(Value Co-Creation)의 중요성이 대두되고 있다. 하지만 기업의 공동가치창출 활동이 모두 성공적인 시장성과를 창출하는 것은 아니다. 이는 공동가치창출을 위한 선행적인 기업역량 확보 미흡에서 기인하며, 또한 고객과의 공동가치창출을 통해 시장변화에 부합하는 혁신적인 신제품 개발 실패에 원인이 있다.그러나 공동가치창출의 선행요인 및 시장성과에 관한 연구는 개념적 연구 및 사례연구 중심으로 이루어져 실증적인 연구가 매우 미흡한 실정이다. 이에 본 연구에서는, 자원기반이론을 기초하여 공동가치창출과 중요한 연관성을 갖는 흡수역량(잠재적 흡수역량, 실현적 흡수역량)을 선행요인으로 제시하여 인과관계를 실증적으로 연구하였다. 또한 공동가치창출이 시장성과에 미치는 효과를 살펴보는 가운데, 특히 혁신성과(제품혁신성과, 공정혁신성과)를 매개로 하여 공동가치창출이 시장성과에 어떠한 영향을 미치는지에 대해 구조모형분석을 통하여 실증연구를 수행하였다. 공동가치창출을 추진하고 있는 국내 309개 제조 기업을 대상으로 분석한 결과는 다음과 같다. 첫째, 실현적 흡수역량은 공동가치창출의 선행요인으로서 유의한 영향을 미치는 것을 확인하였으나, 잠재적 흡수역량은 영향을 미치지 않는 것으로 밝혀졌다. 둘째, 공동가치창출은 기업의 제품혁신성과와 공정혁신성과에 모두 유의한 영향을 미치는 것으로 확인되었다. 셋째, 공동가치창출은 시장성과에 긍정적인 영향을 미치는 것으로 밝혀졌다. 마지막으로, 제품혁신성과와 공정혁신성과는 공동가치창출과 시장성과간의 관계에서 모두 매개효과를 가지는 것으로 확인되었다. 특히, 제품혁신성과는 완전매개역할을 하는 것으로 확인되었다. Tim Brown, the CEO of the representative global innovative global design company IDEO, asserted that unlike the web 1.0 age in which the company provide unilaterally informations toward the consumer, in the web 2.0 age, the consumer cannot be any more treated as a passive consumer but take an active role in product development. As he said, the value co-creation in which the customer take part in the new products development is being more and more emphasized. However, the reciprocal value creation activity doesn’t always create a successful market performance. In many cases, this can result from the insufficiency of some preceding capacities which are indispensable for value co-creation and the failure of innovative product development keeping up with changes on the market. In this study, we tried to find out, based on the resource-based theory, the relationship between the value co-creation and the absorptive capacity. Moreover, as well as the analysis of the effect of value co-creation on the market performance, we also tried to investigate empirically the mediating effect of innovation performance. The data was collected by a survey of 309 domestic manufacturing companies published by Korea Innovation Survey 2014. For the analysis of the data, Structural Equation Modeling – SEM with AMOS program assistance was used. The results of the analysis were as follows. Firstly, realized absorptive capacity, which concerns the development of the product and the service reflecting of the customer’s suggestion and idea, has a positive effect on value co-creation as antecedent factor. On the other hand, it is revealed that potential absorptive capacity, which comprises knowledge acquisition and assimilation capabilities, does not significantly affect the value co-creation. Secondly, the results show that the Value co-creation positively affect both on the product innovation performance and the process innovation performance. Thirdly, the Value co-creation and the innovation performance, including product innovation performance and process innovation performance, have a positive effect on the market performance. Finally, the findings show that the product innovation performance and the process innovation performance have a mediative effect on the value co-creation and the market performance. Particularly, it turns out that the product innovation performance has a complete mediation effect. [그림은 본문 참조] Based on the results, our contributions were follows. Firstly, this study suggests that the absorptive capacity has to be preceded so that the company can create a successful result through the value co-creation. Especially, the realized absorptive capacity turns out to be a very important factor. For this purpose, the company is required to recruit and manage excellent employees including efficient composition of R&D team and systematic education program. Secondly, the company need to raise a competitiveness in the market. For this purpose, the company is required to build platform, community and process which can vitalize customers’ active participation in value co-creation, as well as an introduction of the incentive system, which allows to induce the participation of the customer.

This study investigates the economic factors affecting the dairy farm profitability. The explanatory variables of empirical model were selected based on the previous literature. The ordered logit estimation is employed to resolve the ordered nature of the dependent variable. The results suggest that the explanatory variables such as labor use, the heifer ratio, the pregnant period affect the odds of dairy farm revenue negatively, and the use of helper, management career, daily milk quota, the ratio of grain feed, feed-revenue ratio, the average number of farrowing affect the odds positively. The estimated odds ratios indicate moderate influences of explanatory variables on the dairy farm revenue.
