Restricted by time and space, formal environmental education has a limit in accommodating fast changing socal phenomena and quickly spreading environmental problems. Therefore, to carry out more efficiently the environmental education for middle and high school students, this study is intended to search for a way to establish a network of formal and nonformal environmental education. More than 80% of civil environmental organizations replied they agree to establish a network of environmental education. As for the establishment of a network, they preferred the establishment in which middle and high school, civil environmental organizations, government, the environment-related departments of the universities. They preferred ‘civil environmental organizations’ for the operator, ‘local municipal or provincial level for the scale, ‘direct personal relations’ for the interchange method. To establish a network, they replied that ‘funding’, ‘specialists in environmental education’, ‘staff to proceed educations’, ‘reform of law and systems’ are required. They also preferred ‘funding from government budget’ for a way to fund a network. We can draw the following conclusions from the survey, We need a training program for environmental education staff not to make those educational programs by civil environmental organizations temporary Also, more studies should be done to establish more organized network of environmental education and nonformal environmental education by civil environmental organizations. Environmental problem varies depending on the local characteristics, and thus environmental education should be carried out locally at the network center for environmental education. Besides, local self-governing bodies should support it administratively and financially.

A composite model is used to represent the heterogeneity of plain concrete consisting of coarse aggregates, mortar matrix and the mortar-aggregate interface. The composite elements of plain concrete are modeled using triangular finite element units which have six interface nodes along the sides. Fracture is captured through a constitutive single branch softening-fracture law at the interface nodes, which bounds the elastic domain inside each triangular unit. The inelastic displacement at an interface node represents the crack opening or sliding displacement and is conjugate to the internodal force. The path-dependent softening behaviour is developed within a quasi-prescribed displacement control formulation. The crack profile is restricted to the interface boundaries of the defined mesh. No re-meshing is carried out. Solutions to the rate formulation are obtained using a mathematical programming procedure in the form of a linear complementary problem. An event by event solution strategy is adopted to eliminate solutions with simultaneous formation of softening zones in symmetric problems. The composite plain concrete model is compared to experimental results for the tensile crack growth in a Brazilian test and three-point bending tests on different sized specimens. The model is also used to simulate wedge-type shear-compression failure directly under the loading platen of a Brazilian test.

There communicates using tire supersonic waves in tire underwater, that is different from tire ground that use tire propagation. Because using Law frequency to come under tire waves, bandwidth that is able to communicate is very smaller that tire mobile communication of tire ground. Also, The channel environment changes rapidly in tire shallow underwater than tire ground. Due to such a reason, data transmission technic that is able to tire maximum application to restricted bandwidth and tire signal processing technics that is able to conquer tire rapid changes of tire channel environment are being used. Algorithm is used at tire application of these technic has a lot of tire calculating quantity. So this research reveals small bulk and equal performance using one DSP chip and then implements QPSK transmitter, that uses SHARC DSP of Analog Device company, for tire underwater supersonic waves communication rapidly decrease tire calculating quantity.

This study aimed to predict retail sales of local markets in Jinan city of China with the Huff model. Using the Huff Model, we examined whether the predicted retail sales of local markets may be different in Jinan, China, from the department stores, supermarkets, shopping centers/shopping malls, and home appliance stores. The probability that a customer shops at location depends upon the store size and the travel time factors calculated by the Huff Model. We found that the predictedretail sales of shopping malls have a greater value than others. People who live in a mid-sized city may have easier access to any stores within the city boundary than people in metropolitan areas. Therefore, people in a mid-sized city are more sensitive to store size, because a bigger store size means greater opportunities, incentivizing consumers to travel further to competing stores after passing by nearer, smaller stores. This study has some limitations. First, the data is somewhat restricted in that the subject stores do not represent all of the stores in Jinan. Second, we cannot compare the estimated market share of the stores and the actual sales data. It is further suggested in this study that more databases be developed throughout such East Asian countries as Korea and Japan and that a different parameter λ value in the Huff Model be utilized for mid-sized cities.

Pseudohelice subquadrata (Dana, 1851) is endangered due to its restricted habitat; hence, it has been designated as a marine protected species and endangered species by law in Korea. It has been recorded only Jeju-do and Geomun-do, Republic of Korea. The present study, is the first report on a cytochrome c oxidase subunit I DNA barcode for P. subquadrata. The maximum intra-specific genetic distance among all P. subquadrata individuals was found to be 0.5%, whereas inter-genetic distance within the same genus was 17.2-21.5% compared with Helice tientsinensis (Rathbun, 1931), H. tridens (De Haan, 1835), H. epicure (Ng et al., 2018), and Helicana wuana (Rathbun, 1931). Our barcoding data can thus be used as reference for restoration and conservation studies on P. subquadrata, which are designated as marine protected species.

Here we review the evolutionary history of radiation therapy technology through the festschrift of articles in celebration of the 30th anniversary of Korean Society of Medical Physics (KSMP). Radiation therapy technology used in clinical practice has evolved over a long period of time. Various areas of science, such as medical physics, mechanical engineering, and computer engineering, have contributed to the continual development of new devices and techniques. The scope of this review was restricted to two areas; i.e., output energy production and functional development, because it is not possible to include all development processes of this technology due to space limitations. The former includes the technological transition process from the initial technique applied to the first model to the latest technique currently used in a variety of machines. The latter has had a direct effect on treatment outcomes and safety, which changed the paradigm of radiation therapy, leading to new guidelines on dose prescriptions, innovation of dose verification tools, new measurement methods and calculation systems for radiation doses, changes in the criteria for errors, and medical law changes in all countries. Various complex developments are covered in this review. To the best of our knowledge, there have been few reviews on this topic and we consider it very meaningful to provide a review in the festschrift in celebration of the 30th anniversary of the KSMP.

In contemporary society interest in and consumption of beauty treatment are increasing, raising interest in health and beauty. However, beauty-related laws are becoming factors of hindrance of beauty development. Currently the Public Health Control Act plays a basic role in the beauty art business in Korea, However the contents are in discord with international laws and its definition is not clear. Therefore it is causing conflicts of different occupations and job associations which are similar to art business. Especially, because neither definitions nor policies on beauty care devices exist in the Public Health Control Act, beauty care devices using in foreign countries cannot be used in Korea due to classification as medical devices. Under this circumstance, therefore, beauty care device uses by beauty artists violate the law. The government has tried to solve these irrational regulations. Recently, the Small and Medium Business Administration announced 'the improvement plan of small business and young founders site regulation for public economy recovery' in a ministerial meeting on December 28, 2016. Regulations on policy preparation for skincare devices were inclusive in this announcement. It is the question whether the regulations will be executed or not. Even though beauty industrial competitiveness was presented in the 18th Presidential Council on National Competitiveness in 2009, it was not practiced. The proposal bills for beauty law improvement have been put forth several times since 2000 including an improvement plan for regulating beauty care devices. However, so far there have been no improvements. The damage on the regulation classifying beauty devices as medical devices is not only restricted to skincare. This develops beauty devices and the beauty industry which imports and exports beauty devices. When beauty devices are exported, complicated procedures are unavoidable and when beauty devices are imported, irrational problems like reregistration procedures and costs occur. The reason why an improvement plan has not gone into practice is the resistance of the dermatologists' association. Dermatologists tend to stand positively against harming public health by saying that beauty devices used by beauty artists cause people to suffer side effects. In contrast, anyone who has a licence to use beauty devices is able to use them in foreign countries. It is not only infringement of one's right as a beauty artist but also people's right to receive beauty care services. With this reason, Korean's current law under which beauty devices are ruled as medical devices should be revised with accordance to domestic surroundings. Therefore in order to advance and globalize the beauty industry, the support and cooperation of the Korean government and relevant associations is needed to legislate and revise the beauty devices laws. The relevant associations abandon regional self-centeredness and cooperate to define ranges, size and management of beauty devices for safe use. If no collaboration exists, an arbitration agency should be established to solve the problem.

우리나라의 유통산업분야에는 아직도 법적·제도적 보완시책이 부족하며, 특히 전통시장을 비롯한 중소 영세상인들에 대한 보다 체계적인 육성·지원방안이 시급한 실정이다. 이러한 전통시장을 지원하기 위해 2004년도에 제정된 전통시장 특별법의 지원대상과 범위는 종전에는 단위시장으로 국한하였으나, 이후 시장 및 상점가, 시장활성화구역, 더 나아가 상권활성화구역을 지정하여 지원할 수 있도록 확대시켜왔다. 그러나 전통시장 활성화 및 지원에 관한 기준이 되는 특별법이 전통시장의 개념을 다소 획일적으로 규정함으로 인해 무등록시장에 대한 법률적 개념의 미비함과 같은 문제점을 지니고 있다. 여기서 무등록시장이란 특별법에서 정한 계량화된 기준을 충족하지 못함에 따라 실제 시장기능 수행여부와 무관하게 법률적인 전통시장에 포함되지 않는 시장을 일컫는다. 본 연구는 이러한 특별법 규정에 대한 문제점을 도출하고 개선방안을 찾고자 논의를 전개한다. 사례는 모란민속5일장을 중심으로 한다. 본 연구는 새로운 시각으로 접근하고자 한다. 즉, 경험적인 측면에서 현실에 직접적으로 접목할 수 있는 논의를 하고자 한다. 따라서 최근 이슈화되고 있는 논의 중에 법적 보호를 받지 못하는 무등록시장을 중심으로 논의하는 한편, 연구방법론 측면에서 볼 때 규범적 연구방법론을 견지한다. 유통학 분야에 있어 기존의 연구가 대개는 경험적 분석기법을 많이 활용하지만, 본 연구의 특성상 법적 제도적인 관점으로 접근할 때 가장 효율적인 논의가 되기 위해서는 현장에서 바로 접목이 가능한 규범적 연구방법론을 택하여 본 연구를 전개하고자 한다.
