  • Lean startup is a concept that combines the words "lean," meaning an efficient way of running a business, and "startup," meaning a new business. It is often cited as a strategy for minimizing failure in early-stage businesses, especially in software-based startups. By scrutinizing the case of a startup L, this study suggests that lean startup methodology(LSM) can be useful for hardware and manufacturing companies and identifies ways for early startups to successfully implement LSM. To this end, the study explained the core of LSM including the concepts of hypothesis-driven approach, BML feedback loop, minimum viable product(MVP), and pivot. Five criteria to evaluate the successful implementation of LSM were derived from the core concepts and applied to evaluate the case of startup L . The early startup L pivoted its main business model from defecation alert system for patients with limited mobility to one for infants or toddlers, and finally to a smart bottle for infants. In developing the former two products, analyzed from LSM's perspective, company L neither established a specific customer value proposition for its startup idea and nor verified it through MVP experiment, thus failed to create a BML feedback loop. However, through two rounds of pivots, startup L discovered new target customers and customer needs, and was able to establish a successful business model by repeatedly experimenting with MVPs with minimal effort and time. In other words, Company L's case shows that it is essential to go through the customer-market validation stage at the beginning of the business, and that it should be done through an MVP method that does not waste the startup's time and resources. It also shows that it is necessary to abandon and pivot a product or service that customers do not want, even if it is technically superior and functionally complete. Lastly, the study proves that the lean startup methodology is not limited to the software industry, but can also be applied to technology-based hardware industry. The findings of this study can be used as guidelines and methodologies for early-stage companies to minimize failures and to accelerate the process of establishing a business model, scaling up, and going global.

  • The main goal of this research is to invest the difficulties in the process of developing serious game for science learning to acquire the suggestion. We analysed the journals written by developers of game scenario on the procedure of the development and on the review of the accomplished game. Then we also interviewed the scenario developers as well as game developers. When interviewing the game developers, we passed them the thoughts and questions of scenario developers. The possible difficulties in developing serious game are form the difference of cognitions on the skills which can be embodied in the development process and interaction and communication problem between scenario developers and game developers. As a consequence of the research, we acquired some suggestions for developing serious game as follows; 1) Scenario developers and game developers must understand the concepts of serious game as well as learning theory; 2) Both scenario developers and game developers should be aware of secured technological capacity and allowed time period. 3) Scenario developer should take a part of game developer' role as using a learning contents authoring tool; 4) Scenario developers have to consistently interact with game developers in developing the games; 5) Scenario should be concretely described in detail; and 6) A Supervisor is essential to control both scenario developers and game developers.

  • This study examined all the research published in Journal of Korean Academy of Nursing (JKAN) for last 30 years, from its beginning year to year 1999, based on an objective frame of evaluation. The purpose of this study is to reflect the trend of nursing research in Korea to date, and to provide an optimal direction for future research. The total number of 959 studies were analyzed with the following results. 1. Since 1990s, the number of non-degree based research has been larger than that of degree-based research compared to 1970s and 1980s. Both collaborative and funded research has been particularly increased in a gradual rate. 2. Research on nurses or nursing students has decreased while research on more diverse populations such as patients, patient families, or community-dwelling healthy clients has increased. 3. While essential nursing concepts such as human, nursing, and health have been consistently dealt as main research topics, research related to the concept of environ- ment has been insufficiently conducted. 4. It was remarkable that the quality of nursing research has been improved due to the acknowledgement of the importance of the empirical research method within the nursing community. 5. Qualitative research has appeared in the journal since the late 1990s, but it is still regarded to be in its novice stage. 6. Although the utilization of research findings for expanding the nursing body of knowledge has been wide in diverse specialties, most studies are limited to focus on concept development or evolution yet. also, in some of these research finding are utilization already considerably as to develop nursing interventions. Based on these findings, conclusions are extended to the following discussions: For the last 30 years, nursing research in Korea has shown an acute methodological development in both quantity and quality. However, there has been a lack of research on theory development although it is one of the ultimate goals in nursing. Further research should be empirical enough to be utilized in an actual nursing care context, and thus to be basis of developing culturally competent nursing theories in Korea.

  • In order to prepare for the coming twenty-first century and to meet changing social demands and health needs, it is necessary to improve the curriculum through development of new conceptual frameworks. The purposes of this study were : 1) to assess the needs of the curriculum of the students, the faculty, the graduates, and the nursing supervisors and head murses ; 2) to develop the conceptual framework which includes philosophy and goals of nursing education based upon needs assessment ; 3) to develop level objectives ; 4) to identigy the contents of the curriculum ; 5) and to develop the faculty. The curriculum was assessed and developed from April, 1995 to March, 1996 through twenty four weekly meetings, two seminars, and two workshops. The process and results of this study are as follows : 1. A needs assessment of the present curriculum was done of the 194 students, 177 graduates, 14 faculty members, and 60 nursing administrators in 5 main areas (objectives, planning and organization, teaching-learning process and methods, evaluation, revision of curriculum). The results showed that there were many descrepancies between expectations and actual situations in all the groups and in all the areas. This implies that there was a necessity for total curriculum revision. 2. To develop the conceptual framework, 1) the core concepts were identified(man, health, environment, and nursing) on the basis of the existing educational philosophy and educational objectives of our school, elicited by group discussions using the nominal group method, one of the needs assessment methods, the philosophy and objectives were restated. 2) Six essential componednts were indentified for the conceptual framework from the restated philosophy and objectives ; nursing process, communication, professional roles, client, health, and nursing. The vertical theread consists of the client and health/nursing ; and the horizontal thread consists of nursing process, communication, and professional roles. 3. The contents of the curriculum were selected on the basis of the educational objectives and organized according to the conceptual framework. 4. The level objectives were then restated. It is expected that the objectives of our school will be accomphished through developing the courses, choosing and Implementing, more effective teaching-learning methods, and evaluating the efficacy of changes implemented. The most important factor will be to continually upgrade the faculty and their teaching skills.

  • Recreation planning is essential activity to meet changing demands and to protect the resources. The recreation opportunity specturm(ROS) system is a principal part of a recreational management planning. In this study, the basic concepts and tenets of the ROS system described and reviewed the feasibility of applying to forest recreation planning to the Korean national forest. In Korea, the forest land as a major recreation place has used without the rational planning process. The control for the laissez-faire use on the forest area, the classification of recreational opportunity settings is the most important process and then it make a useful tool for providing proper recreational opportunity and site development guidance. Opportunity settings classification can help maintain diversity and enhance protection of forest resources. It can also improve the quality of recreational experiences and the management action guidances. GIS technology using the ARC/INFO could be useful in current attempts to identify analysis areas for predictive modeling of forest recreation site planning.

  • This study was performed in part with the task to find measures to improve the defining characteristics of feelings, value, interest, self-efficacy, and others aspects in regards to learning math among elementary and middle school students. For this study, it was essential to understand the appropriate questions that are needed to be asked during a consultation at a math clinic, for students that are having a hard time learning math. As a method for performing this study, the content of scheduled counseling over 2 years from a math clinic were collected and the questions that were given and taken were analyzed in order to figure out the types of questions needed in order to effectively examine students that are facing difficulty with learning math. The analysis was performed using Grounded theory analysis by Strauss & Corbin(1998) and went through the process of open coding, axial coding, and selective coding. For the paradigm in the categorical analysis stage, 'attitude towards learning math' was set as the casual condition, 'feelings towards learning math' was set as the contextual condition, 'confidence in one's ability to learn math' was set as the phenomenon, 'individual tendencies when learning math' was set as the intervening condition, 'self-management of learning math' was set as the action/interaction strategy, and 'method of learning' was set as the consequence. Through this, the questions that appeared during counseling were linked into categories and subcategories. Through this process, 81 concepts were deducted, which were grouped into 31 categories. I believe that this data can be used as grounded theory for standardization of consultation in clinics.

  • This research analyzes the economic attitude and economic literacy of college students that attended college or graduated within one year. The study measures diverse traits of economics, such as economic rationality, economic interest, risk aversion, and competitive spirit or selfishness. Results show that students enrolled in economics courses have an interest in economics, received high grades, and graduates have a relatively higher level of economic rationality. Second, students who have taken courses in economics showed a higher level of interest in economics. Thus, the correlation between such education and students' interest cannot be denied. Third, regardless of their experience in taking economics courses, the level of knowledge in economics is low for community college students. Although the rationality and interest of those students enrolled in economics courses are higher compared to students not enrolled in such courses, it does not play a pivotal role in enhancing their economic intelligence. This shows that the current education in economics positively influences an individual's economic traits but does not necessarily generate knowledge in economics. Education should focus more on associating essential economic concepts with real-world issues.

  • Identification and mangement of ecosystem service hotspots are necessary to set environmental policies that include concepts of ecosystem service. Assessment and mapping of ecosystem service hotspot referring areas with high amount of ecosystem services provide essential information to manage ecosystem services effectively. Assessment of hotspots based on regional environmental stakeholders' perception is an useful approach to identify priority areas where management practices are required. This study estimated weights on regulating ecosystem services from regional environmental stakeholders' surveys in Ansan, and then, identified regulating service hotspots with weights. The result indicated that regulating services are, in order of importance, water quality, air quality, erosion, and climate control. The north-eastern forest of Ansan was mainly revealed as an ecosystem service hotspot. Ecosystem service hotspots were spatially distributed similarly regardless of environmental stakeholders' weights. Identification of ecosystem service hotspot with environmental stakeholders' perception can be applied in decision-support tools for ecosystem service management.

  • Development process of agricultural technology has been studied with a case study of Korean agriculture. Technological is considered as a transformer of inputs into outputs and hence technological appropriateness, an important aspect of agricultural development strategies, is considered as a dynamic concepts. Considering the concept of agricultural system as a delivery system for providing essential materials and services to producers and consumers, it has been divided into two major groups of dimensions vis. external challenge dimensions and internal response dimensions. Market, investment and agro-ecosystem constitute the external challenge dimensions : whereas trade , technology as well as production and resources allocation constitute internal response dimensions. The system manager is responsible for maintaining equilibrium in the mentioned six sub-systems. Two kinds of alternatives paths of technological development viz. land saving technology and labour saving technolog have been studied. Technology is considered as a combination of four basic components viz. facilities, abilities, facts and frameworks. Adoption of innovation in agriculture depends on profitability, awareness, risk aversion, financial capacity, institutional infrastructure, availability of physical inputs and adaptability to the local conditions. For a cast study of Korea, changes in the agricultural system through external challenge dimensions are investigated. The impacts of industrialization on agro-ecosystem reported are shift of labour from the agricultural sector to non-agricultural sectors and continuously increasing demand of farm the agricultural sector to non-agricultural sectors accompanied by increase in land prices. The impacts on the commodity market discussed are shift in demand from rice, barley and other cereals to meat , dairy products and vegetables : and increasing in supply capacity of agricultural inputs. The process of agricultural development from 1962 to 19 1 9 (i.e. from start of the first to the end of the sixth five year plan) are also discussed in details with several policy measures taken. The trend of agricultural income and productivity are also analyzed. The main cause of increase in the agricultural income is considered as increase in labour productivity. The study revealed that during the span of 1965-88, holding size has not changed significantly, but both the land and labour productivity increased and so did the agricultural income. R&D activities in Korea have changed over time in three stages vix. import of improved technology, localization by adaptive research and technological mastery. For the new technology to be made affordable to farmers, policy measures like fertilizer and food grain exchange system, dual price system in rice and barely and loan for machinery were strengthened.
