Due to the development of technology and medical care following the 4th industrial revolution, the medical paradigm is shifting towards patient-centered medical services. Based on the development of smart home technology, the residential environment is changing into a residential space that cares for and heals the lifestyles and the healthcare of families. As lifestyle changes, the concept of supporting smart home care based on the residential environment is making it possible to build a smart home IoT service design with enhanced accessibility and convenience for medical appointments and well-being lifestyle care. This paper is a study on user-centered health care smart home IoT service design suitable for family members based on the health care, beauty care, exercise care, and customized diet care beyond the conventional concept of health care monitoring. Based on the analysis, this paper proposes a personal care coordinate smart home service design in a human-centered wellness clinic care smart home service design environment. Human-centered wellness clinic smart home IoT service design is meaningful in presenting a vision for research on smart home service design that links hospital-linked and care-linked service industries, which should be considered from the smart home construction planning stage.

TThe National Cemetery is a space for realizing patriotism at the national level to honor the will of those who gave their lives for the country and to permanently venerate their loyalty and merit. The purpose of the establishment of the national cemetery is to imitate the spirit of patriotism that was sacrificed for the country and people. The state distinguishes between private death and public death as a sacrifice for the state. Furthermore, we carefully manage deaths that are classified as public. National cemeteries are the institutional space for managing such public deaths. With respect for devotion and discipline, the standards for burial and commemoration should not be based on status or class. In a national cemetery, shifting the degree of courtesy and priorities to devotion and discipline will become a true patriotism system in a democratic society. First of all, it is time to honor those who have died and those who have dedicated themselves to the restoration of national sovereignty as the highest and highest priority. This is the key to resolving the conflict that our national cemetery is experiencing and gaining public sympathy. This study is based on the premise that the national cemetery is insufficient as an open memorial space and historical space loved by the people. In addition, the implications and applicability of national cemeteries are reviewed through domestic and foreign excellent cases and high-quality and eco-friendly national cemetery construction cases in advanced countries.

With the recent increase in the number of one- and two-person households, demand for small-sized apartments has been on the rise, and lifestyles have seen swift changes to cater to smaller-sized housing. The construction market is shifting toward small-sized apartments, and research is now needed on the lifestyles of those living in small-sized apartments in order to develop suitable housing units. Therefore, this study aims to produce a planning concept for housing units by lifestyle, categorizing residents based on lifestyle and identifying their LDK preferences. Regarding methodology, prior research was reviewed to validate housing-related lifestyle factors and study the lifestyles of those living in small-sized apartments. Lifestyle categories based on housing type were determined by a cluster analysis, and LDK preferences for each lifestyle were analyzed through a survey. These data were then used to propose a planning concept with small-sized apartments for each lifestyle type. Thirty-two factors for categorizing lifestyles were obtained by studying three domains of housing-related lifestyle factors: 'housing values', 'attitudes toward living space', and 'behavior in living space; A total of 648 people living in small-sized apartments were classified into three lifestyle groups: 'True Family Benefiters', 'Smart Shopaholics', and 'Slow Heritage Pursuers'. 'Each group's lifestyle characteristics and socio-demographic features were used to classify the lifestyles of those living in small-sized apartments. The LDK preferences for each lifestyle were analyzed to design a planning concept for small-sized apartment.

Urban planning is the task to explore measures for bringing order to the change in urban space of future predicted in relation to the size and purpose of the land and a variety of facilities in cities in order to present the environment that can promote the qualitative improvement of activities of residents, ensure orderly urban space of future, and create appropriate urban environment which meets the desire of citizens by anticipating the urban development on the basis of overall activities such as politics, economics, culture, etc, so that the improvement in urban life can be accomplished ultimately. Therefore, this study attempted to examine current conditions information necessary for establishing policies pursuant to the national land development plan and regional development, as well as respond to the needs of urban residents who need the improvement of settlement environment including various amenities for the convenience of life, by shifting away form the macroscopic and one-size-fits top-down approach of development so far and aiming a balanced development of national land in quest for welfare society and by utilizing the urban index as the basic prior task necessary for seeking the shift ind the direction of policies and setting the direction for policies on the basis of the top-down development approach which suits the anticipation and hope of local residents as the subject of development, considering the growing interest in the shift in the policies for regional development in this era of localization. Techniques for urban planning need to be applied, such as the prior planning and the following development, along with the support at the policy level for achieving the improvement in the related sector, in order to induce continuos urban deelopment based on the establishment of healthy and sound settlement environment, and furthermore, the efforts must be drven forward to improve the urban settlement environment while the urban planning and policies are established.

A twenty-one-year-old man visited our hospital due to abdominal distension for a month. On the physical examination, there was severe abdominal distension with fluctuation and shifting dullness. The routine laboratory results were within normal range. On the Magnetic Resonace angiography, there wasn't any blood flow within the right and middle hepatic vein. So we concluded that the etiologic disease was Budd-Chiari syndrome. On the liver scan, there was cold area(absence of radiouptake) on entire right lobe of the liver, increased uptake on the bone marrow and showed splenomegaly. This finding was similar to the liver mass occupying right lobe with underlying chronic liver disease. On the previous reports, it is quite uncommon finding that Budd-Chirari syndrome shows lesion like space occupying one on the liver scan. So we report this case with a review of the literature.

The speed of technological development is increasing, and high-performance digital devices are spreading. Wired digital devices such as PCs have been optimized for existing wired environments, but needs are shifting away from the constraints of space and space to smart work that enables efficient work anywhere and anytime. The Smart Work System security design is needed to secure integrity and availability in the face of various security threats including physical threats (lost, stolen, and damaged terminals), technical threats (data theft, DoS: denial of service), and unauthorized access outside the wired environment. In this study, we analyzed smart work network systems, wired / wireless link systems, and digital smart devices. We also studied cyber-attack analysis and cybersecurity design methods for a Smart Work wired system and a future wireless system. This study will be used as basic data for building a secure Smart Work system.

By reading the main character, Rene Gallimard, in M. Butterfly as a spatial metaphor of America, this article examines how homogeneous American national identity of heterosexuality and white masculinity has been reinforced since the cold war and has constituted a crisis of hegemony with the decline of imperialism and how its pathological symptom is shown through the melancholic suicide of Gallimard. This article also argues how the feminine attributes implied in race, gender and sexuality in M. Butterfly are designated and allegorized as an impure, contaminated and ahistorical marker of national integrity in pthe social and material status of the heterosexual American white male. To develop my argument, I read M. Butterfly from a psychoanalytic point of view. Therefore I depend on Freud, Lacan, and Bhabha's psychoanalysis as the theoretical basis. In this paper, I also argue that the homogenized and fixed national identity is splitted and collapsed from within as shown in the Gallimard's melancholy and in the process of splitting the "Third Space" of hybrid subjects for the marginal and the emergent like Song Liling, a homosexual Asian man, can be built "from a space in-between." Therefore Hwang calls into questions conventions of fixed, essentialist identities through the shifting gender identities between Song and Gallimard in M. Butterfly and how identities in the plural are constructed variously in throughly historicized, politicized situations, and these constructions can be complicated by relations of power.

The binders introduced in Korea were originally designed to be used for Japonica-type varieties which have relatively long stem and are highly resistant to shattering. In order to use it for Tongil varieties which are short and easy to be shattered, mechanical modifications are necessary to reduce a grain loss incurred during binder operation. This study was intended to investigate analytically and experimentally the major sources of grain losses caused by three kinds of binders now introduced in Korea. Actual modification for each of three binders was done and experimentally compared to see if any improvement on grain loss was achieved. The results obtained in this study are summarized as follows; 1. It was required that the power transmission of binder should have a shifting mechanism so that velocities of pick-up and traveling units could be changed independently as desired according to the Japonica-type and Tongil varieties. In other words, the desired velocity of traveling unit should be obtained by shifting the transmission and the velocity of pick-up unit should be selected by reaping clutch according to the variety independent of the velocity of traveling unit as shown in Fig. 6. 2. To reduce grain loss it was desired that the moving parts of the pick-up unit should have the lowest possible velocities in harvesting Tongil varieties, unless the reduction of the speed be hindered the conveyance of the material. Based on the study, it was concluded that the velocities of pick-up unit be reduced by about 35% of those of the existing units. 3. It was found that the lug at the upper rotating section of pick-up case gave a severe impact on the ears of rice to increase grain loss. The optimum design of pick-up case to protect the ears from the protruding part of the lug was recommended by the result of analysis of the trajectory of the end-point of lug at the position. 4. It was proved analytically and experimentally that pick-up unit at the lower-rotating part was the other important source of grain loss in pick-up and divider assembly. In order to reduce a grain loss incurred by lugs at their lower-rotating section, it was suggested to improve it by (1) widening the space between right and left lower-rotating section, (2) shortening the length of lugs, (3) enlargement of the angle between the pick-up case and ground-level, and (4) attaching guard to right and left dividers so that the rotating lug could not give a high impact to the paddy hill. 5. Pick-up and divider assembly of the original binder of three models studied was modified according to the suggestions that were given by the preliminary study. Field test showed that the modified binders were able to reduce grain losses by about 0.4-0.7 percentage points compared to those without modification.

Trees to arrest sand-shifting have been planted on most of coastal dunes in Korea and considered as conservative objects. However, we reconsider that the simplicity of these trees have hindered ecological roles of coastal dunes; geochemical cycle and habitats of endemic species in coastal ecosystem. We examined geochemical properties of sediments on Byunsuran dune field where is planted with pine trees. There are significant difference in properties between embryo dune sediments and foredune sediments, but there are not between foredune and secondary dune. There are no significant difference between pine forest sediments and mixed forest sediments. It is also not showed the difference between dune ridge sediments and swale sediments. Despite spatial diversity from appearance, geochemical properties are not linked with geomorphic and vegetational conditions because of dense planted trees on foredune. To recover natural properties of coastal dunes, we need to change the conservation scheme to increase geomorphic and ecological diversity.

Oval substrates are widely used in automobiles to reduce the exhaust emissions in Diesel oxidation Catalyst of CI engine. Because of constraints in space and packaging Oval substrate is preferred rather than round substrate. Obtaining the flow uniformity is very challenging in oval substrate comparing with round substrate. In this present work attempts are made to optimize the inlet cone design to achieve the optimal flow uniformity with the help of CATIA V5 which is 3D design tool and CFX which is 3D CFD tool. Initially length of inlet cone and mass flow rate of exhaust stream are analysed to understand the effects of flow uniformity and pressure drop. Then short straight cones and angled cones are designed. Angled cones have been designed by two methodologies. First methodology is rotating flow inlet plane along the substrate in shorter or longer axis. Second method is shifting the flow inlet plane along the longer axis. Large improvement in flow uniformity is observed when the flow inlet plane is shifted along the direction of longer axis by 10, 20 and 30 mm away from geometrical centre. When the inlet plane is rotated again based on 30 mm shifted geometry, significant improvement at rotation angle of $20^{\circ}$ is observed. The flow uniformity is optimum when second shift is performed based on second rotation. This present work shows that for an oval substrate flow, uniformity index can be optimized when inlet cone is angled by rotation of flow inlet plane along axis of substrate.
