창업 성공률을 제고하고 실패 가능성을 낮추는 경영전략으로써'린 스타트업'은 2011년 에릭 리스의 책 출간 이후 줄곧 주목을 받아왔다. 전 세계적인 유니콘 스타트업의 등장과 창업 초기기업에 보다 효과적인 성장 방법론으로써의 린 스타트업에 대한 관심 고조에도 불구하고 한국에서는 체계적인 관련 이론연구와 사례 축적이 미진한 상황이다. 경영학의 진정한 발전은 이론과 그것을 기반으로 한 다양한 사례와의 접목이 이루어질 때 가능하다. 이에 본 논문에서는 서비스 개발 초기부터 린 스타트업의 개념이 적용되었고 서비스와 고객 개발의 전 과정에서 린 개념이 적극적으로 도입된 한국기업 '카닥'의 사례를 발굴하고 고찰하였다. 본 연구를 통해 알게 된 사실은 다음과 같다. 첫째, 린 스타트업 적용을 위해서는 우선 린 스타트업을 적용하려는 경영진, 팀원 들이 모두 그 개념을 깊이 이해하고 적용의 필요성에 공감해야 한다. 둘째, 수많은 논의보다 빠른 MVP(최소요건제품)의 출시가 우선이다. 셋째, 효과적인 학습을 하기 위해서는 적합한 분석툴과 핵심지표(Key Metrics) 선정이 무엇보다 중요하다. 넷째, 만들기-측정-학습(Build-Measure-Learn)의 사이클을 통해 지속적으로 측정하고 배워 제품/시장 적합성(Product/Market Fit)이 검증되었다면 과감히 규모를 확장해야 한다. 다섯째, 신규사업 진출도 철저히 린 하게 해야 한다. 카닥은 현재 신규사업으로 확장을 꾀하는 중으로 이 역시 린 스타트업 방법론을 철저히 적용하여 시범서비스(MVP)로 그 가능성을 타진해 본 후 투자를 본격화 한다. 본 연구는 린 스타트업에 관련한 기존 개념의 논의와 더불어 그 적용사례가 축적되고 있는 외국과 비교해, 한국 기업의 사례연구가 절대적으로 부족한 현 상황에서 한국의 대표적인 린 스타트업 활용 사례를 고찰하였다는 점에서 의의가 있다고 할 수 있다. 본 연구가 린 스타트업 방법론의 국내 적용과 향후 관련 연구에 하나의 디딤돌이 되기를 바란다.

An investigation was carried out to assess the carcass characteristics and meat quality aspects of immunocastrated male pigs of medium genetic potential for lean meat deposition in carcass (53 to 55%). When the crossbred Large White x Landrace pigs (n = 45) were 70 days old, they were distributed in a totally randomized design in three treatments (castrated males, females and immunocastrated males) with three replicates of five animals. The pigs were slaughtered when they were 140 days old. Carcass temperature and pH were recorded twice, at 45 min and 24 h after slaughter. The carcasses were evaluated for hot and cold carcass yield, commercial cuts yield, length and depth, back fat thickness, loin eye area and lean meat percentage. The Longissimus dorsi muscle was extracted for analysis of color ($L^*$, $a^*$, $b^*$), exudate loss, cooking loss and centesimal and sensorial analysis of the meat. There were no significant differences for the evaluated parameters between castrated males, immunocastrated males and females, except for backfat thickness between the 7th and 8th thoracic vertebra and the point P2 (lower for immunocastrated males) and carcass temperature at 45 min post slaughter (higher in immunocastrated males), however, this did not interfer with the rate of pH decrease post mortem and the meat quality. The results from this research did not indicate a benefit of immunocastration on carcass characteristics of pigs of medium genetic potential for lean meat deposition in carcass, when compared to surgical castration.

In order to reduce NOx emissions in the 20kW class microturbine under development, the low NOx characteristics, as being an application to the lean premixed combustion technology, have been investigated. The study has been conducted at the conditions of high temperature and high pressure. Theair from a compressor with the pressure of 2.5bar, 3.0bar, 3.5bar was supplied to the combustor with the temperature 560K through the air preheat-treatment. The sampling exhaust gas was measured at the immediate exit of the combustor. For the effect of temperature on NO and CO emissions, though NOx were increased, CO was decreased with increasing inlet air temperature. With increasing inlet air pressure, NOx were increased and CO was decreased also. NOx were decreased, but CO was increased with increasing inlet air mass flow rate. The test has been performed on the equivalent ratio of 0.10 to 0.16 in the lean region. NOx were increased with increasing equivalent ratio, but CO was decreased as an influence of flame temperature. CFD work with an appropriate combustion model predicated a complicated swirling flow pattern in the combustor, and also produced a numerical value of NOx and CO emissions which was to be compared with the experimental one. As the results of this study, NOx are expected to be reduced to less than 42ppm at 15% O2 when operated at the design condition of the 20kW class microturbine.

Purpose As the use of social network services has become common, it has become possible to freely communicate and establish relationships with other people anytime, anywhere for communication and information sharing. Influencers who have a strong influence on consumers' perceptions and attitudes through their own opinions and stories have appeared on various social media channels such as YouTube. Recently, companies utilize influencers with a large number of followers to check interactions with customers to understand customer attitudes and opinions about products in real time. Start-ups with insufficient resources need to quickly examine customer responses to reduce the probability of failure after product planning. The Lean process of creating an MVP and quickly confirming and learning the market response should be repeated over and over again. Findings In this paper, we try to suggest that the YouTube platform can play a sufficient role as a customer experiment space through examples. The case company is a company that has successfully commercialized products by continuously interacting with customers through the YouTube platform for the first four months of its founding. This paper is expected to be helpful in the experimental process for prospective founders and early founders to examine customer responses to reduce the probability of market failure before commercialization. Design/methodology/approach This paper analyzed the YouTube channel data of case companies based on the netnography methodology and presented the contents of the lean process management carried out in the experimental stage and the post-production stage through interview research.

This treatise deals with the profitable suit image design of middle-aged men by examining visual effects in physical design. The sample of this study is people who lives in Kwangju, the Republic of Korea and 20-50 age's men and women. And it is very variety in each population statistics factors the differences of associate design visual effect which considering the difference of sex and age group, numbers of button, a figure and material pattern. Firstly, look into the associate design visual effect by sex and button number. In men's group, the style with three buttons was the most attractive and that with two buttons was the least attractive. In 50's group, the style with two buttons was the least attractive and those with 1.3 and 4 buttons were a little attractive. Secondly, in the difference of associate design with sex and shape, men's group was considered that standard type was the most attractive shape, women's group was thought that lean and standard types were the most attractive shape. So we can know that the attractive shape is different with sex. In the difference of association design with age and shape, 20's considered that standard type was the most modernistic and fat type was the least modernistic. 30's considered that lean type was the most modernistic and 50's thought that fat type and standard type were the most modernistic. Thirdly, see the sex and material pattern. In familarity, men's group considered that stripe pattern was more familiar than checks and plain patterns. And they considered that striped pattern and plain was more manly than checks. In sex and material pattern, 20's thought that plain was the most attractive, stripe was the next, and checks was not attractive. 40's estimated that plain and stripe were more attractive than checks. 50's judged that stripe was the most attractive material. Thus. the attraction is different with ages and material patterns.

Management of today's dynamic projects requires a shift of focus from product to process. The purpose of traditional project controls is to conform performance to plan. The purpose of lean project controls is to make the best possible choices at each point in time during the course of the project, as well as contributing knowledge to the parent organizations so they can learn from project experience. The Lean Construction Institute(LCI) proposed the Last Planner System(LPS) capable of accomplishing that purpose, principally through controlling the quality of planning and of management processes themselves, as distinct from concentrating exclusively on project performance. The case project was a pilot project for the implementation of the Last Planner. Consequently, the coordination of the work on this project was extremely successful. The project had its share of challenges. The coordination did not prevent design problems, or supplier errors, but helped the team deal with the problems effectively while maintaining the work flow. The last planner helped the contractors know: a) who will be doing what and where, b) what each one needs from the others, and c) what are the project priorities. The system itself created a more collaborative environment, because it 'demands' that the subcontractors address these issues.

The influences of number of spark plug on ignitability, combustion characteristics and combustion promotion effect were examined to establish the design conception of spark ignition system for lean burn. Ignitability was increased remarkably by increasing of number of spark plug at combustion wall. Combustion duration was shortened and maximum combustion pressure was increased in accordance with increasing of spark plug number. Rate of overall combustion promotion considered of combustion duration and combustion pressure was 28% in two point ignition and 40% in four point ignition. It was verified that heat release, heat loss and combustion duration were affected by flame area, heat transfer area and maximum flame travel distance respectively.

This paper presents the response surface optimization method using three-dimensional Navier-Stokes Analysis to optimize the shape of a axial flow fan. Reynolds-averaged Navier-Stokes equations with k-$\epsilon$ turbulence model are discretized with finite volume approximations. Regression analysis is used for generating response surface, and it is validated by ANOVA. Five geometric variables, i.e., distribution of sweep angle at mean and tip, lean angle at mean and tip, and spanwise location of mean were employed to optimize the efficiency. The computational results are compared with experiment data. As a main result of the optimization, the efficiency was successfully improved.

Design of personnel teams has been studied from diverse perspectives; the most common are the people and systems requirements perspectives. All these point of view are linked, which is the reason why it is necessary to study them simultaneously. Considering this gap, a decision making model is developed based on factors, models, and requirements mentioned in the literature. The model is applied to a real case. The findings indicate that the Personnel Behavior Based Lean model (PBBL) can be converted into a decision making model for the selection of team members. The study is focused not only on the individual candidates' knowledge, skills, and aptitudes, but also on how the model considers the company requirements, conflicts, and the importance of each person to the project.
