The purpose of this study is to determine the personalizing characteristics of detached housing that reflect the housing needs according to the residents' participation in the back-to-countryside community village. For this study, 15 households of Jagun-maul at Namwon in Jeonbuk provided responses to the semi-structured questionnaire on housing consciousness, housing needs, and views on lifestyle. In addition, 15 plans were analyzed about the shape of the plan, the composition of LDK, the type of access, and the type of special space. The results were as follows. 1) The number of households under the elementary education stage was larger than the number of households above the middle education stage. Most of the households revealed the housing consciousness of 'house as resting place'. Households under the elementary education stage showed a housing consciousness for family-oriented life and households above the middle education stage showed a housing consciousness to interact with neighbors. 2) Households under the elementary education stage preferred LK style while households above the middle education stage preferred LDK style. Most of the floor plans had a front entrance and sliding door for the access from living room to garden. 3) Special spaces such as a loft, 'Ondolbang' (room with underfloor heating), study, maru, 'Toenmaru' (narrow wooden porch), family room, workroom, and toilet with outside door were arranged on each floor plan.

This study compared the perception, necessity, and satisfaction of free school foodservice among parents of students with and without access to free school foodservice. The sample included parents of students with access to free school foodservice (FSF group, 250 parents) or paid school foodservice (PSF group, 250 parents) in Taean, Chungnam. With regard to perception of school foodservice, 30% of PSF parents responded that it is a necessary part of school education, whereas 52% of FSF parents considered it as a part of national welfare service; this difference was significant (P<0.001). In terms of positive remarks, most parents in the PSF group highlighted convenience whereas the FSF group answered that their children were penalized; this difference was significant (P<0.001). In addition, 94% of PSF parents and 96.8% of FSF parents indicated that school foodservice is necessary. In terms of the perception of the free school foodservice, more FSF parents (96.4%) than PSF parents (84.4%) answered that they knew free school foodservice well; this difference was significant (P<0.001). With regard to target recipients of the free school foodservice, most parents in the PSF group said that needy students should be selected, whereas the FSF group said that all students should be eligible; this difference was significant (P<0.001). Acceptance of free school foodservice in the FSF group (34.4%) was significantly higher than that in the PSF group (23.2%). Satisfaction with free school foodservice was 3.5 points in the FSF group, which was significantly higher than the 2.9 points in the PSF group (P<0.001). In summary, parents of students with access to free school foodservice showed more positive perception and higher satisfaction than parents of students with paid school foodservice. This study recommends that parents' suggestions be considered and further perception and responses on free school foodservice be investigated.

A series of revolutionary industrial changes took place from the 18th century of the First Industrial Revolution. The fourth industrial revolution is a new industrial revolution in which intelligence and information unite. Social, cultural, economic and educational systems are expected to emerge within the category of access and experience. In the course of intelligent mechanization, manpower and machinery need to be commandeered. Tools should be left to the machine and humans should look at essential issues. In the 4th Industrial Revolution, the paradigm of education should fundamentally change. Instead of routine technologies based on memorization, one should learn how to access and utilize. It needs to focus on areas of debate, cooperation, communication, sensibility, and artistry that robots and artificial intelligence can not afford. The fourth industrial revolution is the fusion of human beings and technology, the humanities and the technology.

The conventional semiconductor equipment has adopted SRAM module as the test pattern memory, which has a simple design and does not require refreshing. However, SRAM has its disadvantages as it takes up more space as its capacity becomes larger, making it difficult to meet the requirements of large memories and compact size. if DRAM is adopted as the semiconductor inspection equipment, it takes up less space and costs less than SRAM. However, DRAM is also disadvantageous because it requires the memory cell refresh, which is not suitable for the semiconductor examination equipments that require correct timing. Therefore, In this paper, we will proposed an algorithm for punctuality guarantee of memory-free inspection equipment using DDR2 SDRAM. And we will produced memory controller using punctuality guarantee algorithm.

Recently, park usage for environmental education has gained popularity in Seoul. Therefore this study was performed by analyzing the status and problems of nature classrooms in neighborhood parks and citizen's parks that are located in residential areas in Seoul, and then by suggesting improved methods and user programs. The results of this study are summarized as follows. 1) 18 out of 281 neighborhood parks and citizen's parks have nature classrooms in Seoul. Facilities of nature classroom are comprised of direction signs, plant name card, pond, pavilion, pergola, bench, green house, waste baskets, lighting, drinking fountain and others. However, they have many problems in terms of quality. Nature classrooms were classified into three types according to their location in each park. Among the three types, the most popular type was the one that is a part of a park A Total of 479 species of plant (155 species in tree, 324 species in herb) were planted in nature classrooms. There are many kinds of environmental education user programs, but these are not connected with the nature classrooms. Most nature education programs in nature classrooms were self-guided. 2) The Problems that appeared were the featureless place composition, a lack of programs related to nature classrooms, access restriction to certain natured areas, and so on. 3) Finally, this study suggests some solutions to the problems of nature classrooms in urban parks. The solutions include full access to the parks, the creation of diverse theme, and setting up interesting panel and leaflets in order to encourage more active self-guided education.

Background: Pinch-off syndrome (POS) is a rare complication after totally implantable venous access device (TIVAD) implantation. In cancer patients, it is important to prevent this rare complication and to recognize it early if it does occur. We present a case series of POS after TIVAD implantation and the results of a literature search about this complication. Methods: From July 2006 to December 2015, 924 permanent implantable central venous catheter implantation procedures were performed. The most common indication was vascular access for chemotherapy. Results: POS occurred in 5 patients in our clinic. Two patients experienced POS within 2 weeks, and the other 3 patients were admitted to department of surgery, Istanbul Faculty of Medicine at 6 to 14 months following implantation. The catheters were found to be occluded during medication administration, and all patients complained of serious pain. The transected fragments of the catheters had migrated to the heart. They were successfully removed under angiography with a single-loop snare. Conclusion: POS is a serious complication after TIVAD implantation. It is important to be aware of this possibility and to make an early diagnosis in order to prevent complications such as drug extravasation and occlusion events.

This study aimed to analyze open access features of 1,890 Korean scientific journals registered in the Korea Citation Index (KCI). To this end, this study classified open access features of the target scientific journals into two main aspects, free access and free redistribution. The analysis results indicated that the target scientific journals had strong free access aspects. Based on websites, 67% of the target scientific journals allowed for free access without a login process and based on free database, 48% provided free access. On the other hand, the target scientific journals had weaker free redistribution aspects compared to their free access aspects. Only 14% of them offered the CC (creative commons) license. Another finding was that there were clear differences in open access aspects by academic field. Medicine, pharmacy, natural science, agriculture, fisheries, oceanography, and engineering had stronger open access aspects than humanities, sociology, arts, physical education, and interdisciplinary science. It appears that the difference was caused by the presence or absence of organizations supporting distribution of scientific journals of the fields concerned. To narrow the gap, it is recommended that the open access governance system is established to set up open access policies for Korean scientific journals regardless of academic fields and to support them.

Traditional designs of cognitive radio (CR) focus on maximizing system throughput. In this paper, we study the joint overlay and underlay power allocation problem for orthogonal frequency-division multiple access-based CR. Instead of maximizing system throughput, we aim to maximize system energy efficiency (EE), measured by a "bit per Joule" metric, while maintaining the minimal rate requirement of a given CR system, under the total power constraint of a secondary user and interference constraints of primary users. The formulated energy-efficient power allocation (EEPA) problem is nonconvex; to make it solvable, we first transform the original problem into a convex optimization problem via fractional programming, and then the Lagrange dual decomposition method is used to solve the equivalent convex optimization problem. Finally, an optimal EEPA allocation scheme is proposed. Numerical results show that the proposed method can achieve better EE performance.
