본 연구의 목적은 제주도 촌락지역에 있어서 귀농 귀촌인구의 증가로 인한 촌락지역의 변화를 고찰하는데 있다. 특히, 귀농 귀촌인구 증가에 따른 비 농업적 경제활동의 증가와 지역조직에 초점을 두어 촌락지역의 변화를 분석하였다. 제주도 촌락지역으로의 귀농 귀촌인구 증가는 촌락지역에서의 관광서비스업체의 증가를 가져왔다. 그로 인해 촌락지역내에서는 서비스공간의 조성과 함께 토지이용에서의 변화가 나타나고 있다. 한편, 귀농 귀촌인구에 의해 결성된 지역조직은 기존 촌락지역의 조직과는 조직 구성원, 조직 활동과 활동추진체제에서 상당한 차이를 보인다. 사례조직인 서귀포시귀농귀촌협동조합은 촌락지역에서 결성된 조직임에도 불구하고 도시적 성격을 띤다.

The measurement of the key product quality index plays an important role in improving the production efficiency and ensuring the safety of the enterprise. Since the actual working conditions and parameters will inevitably change to some extent with time, such as drift of working point, wear of equipment and temperature change, etc., these will lead to the degradation of the quality variable prediction model. To deal with this problem, the selective integrated moving windows based principal component regression (SIMV-PCR) is proposed in this study. In the algorithm of traditional moving window, only the latest local process information is used, and the global process information will not be enough. In order to make full use of the process information contained in the past windows, a set of local models with differences are selected through hypothesis testing theory. The significance levels of both T - test and χ² - test are used to judge whether there is identity between two local models. Then the models are integrated by Bayesian quality estimation to improve the accuracy of quality variable prediction. The effectiveness of the proposed adaptive soft measurement method is verified by a numerical example and a practical industrial process.

Purpose The purpose of this study is to analyze the impact of policy changes in Busan's local currency, Dong Baek Jeon, on the use of Dong Baek Jeon. In particular, this study tried to investigate consumption changes due to changes in local currency policy depending on the region, industry, and consumer characteristics. Design/methodology/approach This study used the transaction data of Dong Baek Jeon franchise for analysis. Specifically, the data from January 2022 to December 2022 were used to analyze the current status of the use of Dong Baek Jeon and changes in consumption before and after policy changes. Findings As a result of the analysis, the consumption of Dong Baek Jeon tended to be concentrated in specific regions, industries, and ages. In most regions and ages, the top consumption industries were similar. The use of Dong Baek Jeon showed a clear change in the pattern of use depending on policy changes. Specifically, when the benefits were revised downward, the use of Dong Baek Jeon decreased, and when it was revised upward, it increased. Depending on the policy change, the rate of increase and decrease by region and consumer characteristics was relatively similar, but it was confirmed that there was a difference in the rate of increase and decrease depending on the industry.

We investigated the change in land-use alteration in a 45 km × 45 km area around the Upo wetlands in 1920s(before the Japanese occupation period), 1950s(immediately Korean independence) and the period 1970s to 2000s. These data can guide in understanding surface environmental changes in the lower Nakdong River from the early 20^th century to the present. The influence of the long-term decreasing trend of the wetland area at the Upo Swamp was evaluated using a high-resolution local circulation model. The cooling effect of the wetlands on surface air during the daytime in summer(e.g, early August) was approximately 2℃ greater in the 1920s than in the 2000s, which is attributed to wider water areas in the 1920s. Additionally, long-term changes in land use have caused changes in the convergence zone of local circulation wind.

The purpose of this paper is to find an appropriate policy for local government innovation step by step. In order to accomplish this purpose, we considered the characteristics and situation of Gumi city. Specifically, we analyzed the win-win strategy of the department for the largest local administration innovation. Finally, we found that the chief executive's leadership and other strategies such as the adjustment of the innovation propulsion system are key factors. Also, Managing the resistance to change appeared during the process of local administrative innovation is important . The failure of the policy for local government innovation is caused by the failure to manage the resistance Thus for government innovation to succeed, correct informal ion provision, comprehensive participation of public officials and effect ive management of resistance is necessary.

Under the rule of Japanese Imperialism, there were two kinds of architectural government organizations inside the Chosun(朝鮮) Governor-General which designed To(道) and Pu(府) government office buildings; one was the organization inside the central government office and the other inside the local government offices(To and Pu). By the administrative approval procedure of the Chosun Governor-General, the local architectural organization planned site and floors of the building in the schematic design stage, and in the detail design stage not only the central but sometimes the local planned the building design. The design accomplished by the local in schematic stage was believed as a kind of guideline in detail design and the local organization was able to insist their own needs to the central and to change the central's planning. Even though the central had the authority of the design, the local took part in the planning of To and Pu government office buildings at least in the schematic design stage.

In this study, the cytotoxicity of commonly used local anesthetics was evaluated on odontoblasts which are essential for pulpal homeostasis in vitro. Local anesthetics, such as articaine, bupivacaine, levobupivacaine, lidocaine, mepivacaine, prilocaine, and procaine, were tested on the odontoblast cell line, MDPC-23. The concentration-and time-dependent cytotoxic effects of local anesthetics on odontoblasts were measured by MTT assay. Among local anesthetics treated for 18 h, only bupivacaine significantly showed cell death in a concentration-($LC_{50}=1.2mM$) and time-dependent manner. To confirm cell death induced by bupivacaine, the observation of cell morphology and FACS using Annexin V and propidium iodide (PI) staining were performed. As a result of Annexin V and PI staining, as well as the morphological change, only bupivacaine induced apoptotic cell death on odontoblasts when compared with levobupivacaine and lidocaine. These results suggest that bupivacaine might affect normal pulpal integrity even after uneventful local anesthesia.

South Korea's energy policy has been historically established through an energy production structure that relies on thermal and nuclear power generation in relation to a centralized 'Hard Energy System'. However, climate change issues are forcing the transition to renewable energy, and it is crucial for local governments to enable this. This study analyses Seoul city's local energy governance, which is known as One Less Nuclear Power Plant Initiative, by applying the collaborative governance framework inspired by Ansell and Gash (2008) and the Reflexivity framework of Confucianism. It is considered that the local energy governance model of Seoul city can be used as a model by other local governments, and it will eventually lead to a decentralized energy system in this era of energy transition.

현재 사용하고 있는 임목 재적표는 전국 공용으로 제작되어 있기 때문에, 특정 지역에 적용할 경우 재적을 과소 또는 과대 추정하는 문제점을 가지고 있다. 따라서, 본 연구는 이러한 문제점을 해결하기 위하여 수간곡선식을 이용하여 지역의 재적생장을 잘 반영할 수 있도록 홍천과 영주지역의 지방별 임목 수간재적표를 개발하고자 수행하였으며, 우리나라에서 가장 많은 분포를 보이고 있는 소나무를 대상으로 개발하였다. 추정에 적합한 수간곡선식의 도출을 위해서 Max & Burkhart, Korzak 그리고 Parresol et al.의 세 가지 수간곡선 모델을 적용하였으며, 적합도, 편의, 잔차의 표준 오차 등의 통계량을 분석하여 각 모델의 적합성을 평가하였다. 그 결과 3개의 수간곡선 모델간에는 정확성에 대한 유의적인 차이가 없으나, 소나무의 수간생장을 표현하는 데에는 Kozak 모델이 가장 적합한 것으로 나타났다. 따라서 Kozak 모형을 이용하여 소나무의 지방별 수간재적표를 조제하였다. 새롭게 개발된 지방별 수간재적표와 전국단위의 소나무 수간재적표와 비교한 결과, 홍천과 영주 2지역 모두에서 현재 재적표보다 재적이 높은 것으로 나타났으며(0.000< ${\alpha}=0.05$), 또한 두 지역간 지방별 재적표의 재적에서도 통계적으로 유의한 차이를 보였고(p-value: 0.000< ${\alpha}=0.05$) 홍천이 영주에 비해 재적이 높게 나타났다.
