Local festivals form the regional cultures and atmosphere of communication; they increase the demand of domestic tourism businesses and thus, have an important role in ripple effects (e.g. regional image improvement, tourist influx, job creation, regional contents development, and local product sales) and economic revitalization. IoT (Internet of Thing) technologies have been developed especially, beacon-one of the IoT services has been applied as plenty of types and forms both domestically and internationally. However, notwithstanding expansion of current digital mobile technologies, it still remains as difficult for the individual to track the information about all the local festivals and to fulfill the tourists' needs of enjoying festivals given the weak strategic approaches and advertisement activities. Furthermore, current festival-related mobile applications don't function well as delivering information and have numerous contents issues (e.g. ways of information delivery within the festival places, independent application usage for each festival, one time usage due to one time event). This research, based on the background mentioned above, aims to develop the local festival mobile application and data analysis system applying beacon technology. First of all, three algorithms were developed, namely, 'festival crowding algorithm', 'visitor stats algorithm', and 'customized information algorithm', and then beta test was followed with the developed application and data analysis system. As a result, they could form the database of visitors' types and behaviors, and provide functions and services, such as personalized information, waiting time for festival contents, and 'hot place' function. Besides, in Google Play store, they also got the titles given with more than 13,000 downloads within first three months and as the most exposed application related with festivals; and, thus, got credited with their marketability and excellence. This research follows this order: chapter 2 shows the literature review of local festival related with technology development, beacon service, and festival application. In Chapter 3, design plans and conditions are described of developing local festival mobile application and data analysis system with beacon. Chapter 4 evaluates the results of the beta performance test to verify applicability of the developed application and data analysis system, and lastly, chapter 5 explains the conclusion and suggests the future research.

Contemporary era has witnessed a diversity of emotion and emotions being expressed through consumption. This paper examines the relationship between social paradigms and emotional design by means of literature study. In sections 2 and 3, I examine the prevalent social paradigms and the concept/development of emotional design. In section 4, I show the correspondence between social paradigms and specific types of emotional design. More specifically it is shown that "pluralism and decentrality" has led to fun design, individual design and participative design; "emotional revolution" has given rise to multi-sensory design, design with positive feelings, design with negative feelings and aesthetic design; "non-materialistic values" have their correspondence in design as performance and story-telling in design; and "organic worldview" finds its expression in ecological design with a wellness emphasis, and in interactive emotional design.

This study was designed to investigate the changes in physicochemical and sensory characteristics of traditional kochujang during aging, which was prepared with a different meju fermented for various periods of time. The non-volatile organic acid contents in all samples gradually increased up to 90 days of fermentation. Kochujang prepared with a 40-day-fermented meju had $1.14{\sim}2.54$ times highter organic acid content after 90 days of aging as compared to other kochujang preparations. The most abundant free sugars were found to be glucose and fructose representing $82.27{\sim}100%$ of total free sugar contents in kochujang. 17 kinds of free amino acid including Glu, Asp and Met were found in traditional kochujang aged for 90 days. Glu was noted as the most contributing amino acid to the brothy taste of kochujang in the light of increasing ratio and content of Glu among free amino acids during aging. The total free amino acid contents of kochujang increased with an Increase in fermentation time of meju. Results of sensory evaluation revealed that kochujang prepared with a 40-day-fermented meju was best in terms of flavor and taste. These results suggest that kochujang prepared with a 40-day-fermented meju had the highest quality in terms of physicochemical and sensory characteristics of kochujang.

The ROK military conluded that the dead of a young soldier, walking back to his unit was caused by a ricochet after carrying our some construction work near firing range in Gangwon Province in last Septemebr. But when it was revealed that he was hit by a stray bullet cause, this fact caused public fury. To solve these problems, we will analyze the individual fire shooting range of our military units from a safe perspective and propose ways to improve it by applying the cases of the United States, which are both permanent and scientific.

해안역에서의 대규모 개발은 파랑에너지의 전파에 상당한 변화를 초래한다. 특히, 항만내로 전파되는 파랑장을 변화시켜 기존의 에너지 전달체계에 큰 영향을 야기한다. 따라서, 이러한 파랑에너지의 변화를 사전에 예측하여 항만내의 선박이나 항만구조물의 피해를 막을 수 있다. 그러나 일반적으로 수행되는 항만내의 파랑장 검토 즉, 정온도 검토는 주로 공학적으로 문제가 되는 주기 10~20sec의 풍파와 너울성 파랑에 대하여 수행되고 있다. 그러나 실제 현장에서는 20sec 이상의 장주기 파랑에 의한 선박이나 항만구조물에 상당한 피해를 가져오기도 하지만 이로 인해 연간 부두 접안율이 낮아 항만운영에 어려움을 겪고 있다. 본 실험은 대규모 개발에 따른 장주기 파랑에 의한 반응특성과 부진동의 영향을 검토하였다. 특히, 항내 수제선에 개발이 집중적으로 이루어져 내륙측으로 항만수역을 보완하거나 변경이 어려운 경우 장주기파로 인한 부진동의 영향을 저감하기 위한 시도로 공진수역을 도입하였으며, 이에 대한 반응 특성을 분석하여 장래 항만 재배치 계획에 반영할 수 있는 근거가 될 수 있을 것으로 본다.

Organic acids of Kochuzang (red pepper paste) prepared from glutinous rice, polished barley, wheat flour and sweet potato were analyzed by a gas chromatography. Lactic, pyruvic, succinic, fumaric, malic, pyroglutamic and citric acid were identified. And trace amount of oxalic acid was found in the Kochuzang prepared from sweet potato. The dominant organic acid of all samples was pyroglutamic acid, followed by pyruvic and citric acid. The organic acids were lower in Kochuzang from wheat flour than in other samples. The contents of succinic and fumaric acid were highest in Kochuzang prepared from sweet potato and were lowest in polished barley Kochuzang.

Although the round length for tunnel excavation has a major technical and economical impact in conventional tunnelling, there is no coherent procedure available for its determination. In this study, the influence of round length on the behaviour modes of weak rock tunnel was investigated by numerical analyses. Quantitative estimation of the behaviour modes of the face and the unsupported span was established by use of the safety factor for the face stability and the conditional chart. In addition, the optimum round length in the tunnel design stage was investigated based on the detail construction information such as cycle time and material costs. Although this proposed method has some restrictions, it is expected to provide useful information for the optimization of the tunnel excavation, especially in design stage.

There has been a great deal of controversy in the views on the impact of the pesticide pollution from the golf courses. The stream and reservoir associated with a existing golf course were investigated. The parameters include the ones related with eutrophication, heavy metals, pesticides. and aquatic ecological conditions. It was found that the impact on the aquatic ecosystem by the pollution from the golf course was not so serious. An aquatic ecological food chain was well established in the reservoir which belongs to the golf course. In contradiction to the general recognition, the livestock farming and agricultural farming gave much more adverse impacts on the stream than the golf course.

Currently, Korea shares culture, economy, and society together as a member of the international community along with rapid economic growth. In particular, in the 2000s, the construction of local cultural performance halls has been promoted through efforts and methods for the development of local culture. As a result, many local governments built medium-sized or larger performance halls, and achieved both quantitative and qualitative effects by satisfying citizens and attracting visitors. However, this study aims to analyze the safety of the space used by many visitors at the same time and whether an effective evacuation plan is applied to frequent disasters and disaster situations in recent years.
