This paper suggests using the ICP (Iterative Closet Point) algorithm to compensate a two-dimensional map. ICP algorithm is a typical algorithm method using matching distance data. When building a two-dimensional map, using data through the value of a laser scanner, it occurred warping and distortion of a two-dimensional map because of the difference of distance from the value of the sensor. It uses the ICP algorithm in order to reduce any error of line. It validated the proposed method through experiment involving matching a two-dimensional map based reference data and measured the two-dimensional map.

The objective of this study is to apply the modular furniture system, which has been developed actively in western Europe and America since 1970's, to Korean contemporary furniture having converted into western style gradually. The factors requiring the modular furniture system in today's residential environment are as follows; 1. Population increase and urbanization 2. Development of industrial technology 3. Improvement of living condition and change of life style. As these factors increase the problem of diminishing space, multiple functional modular furniture concept has become a solution. Reviewing the current scene of the western modular furniture system, it is classified into modular seating system, mopular wall system, modular commode system and modular storage system. Korean wardrobe, which is am mixed style of traditional and contemporary furniture, should change to a closet eventually because of the grand size and unpractical use of space. Since most Korean family, however, have wardrobes already, it will be necessary to have a turning period to systemized the closet space in Korean residential interior. For the turning period, application of the modular wall system would be one answer to substitute the wardrobe.

Classical cryptography with complex computations has recently been utilized in the latest computing systems to create secret keys. However, systems can be breached by fast-measuring methods of the secret key; this approach does not offer adequate protection when depending on the computational complexity alone. The laws of physics for communication purposes are used in quantum computing, enabling new computing concepts to be introduced, particularly in cryptography and key distribution. This paper proposes a quantum computing lattice (CQL) mechanism that applies the BB84 protocol to generate a quantum key. The generated key and a one-time pad encryption method are used to encrypt the message. Then Babai's algorithm is applied to the ciphertext to find the closet vector problem within the lattice. As a result, quantum computing concepts are used with classical encryption methods to find the closet vector problem in a lattice, providing strength encryption to generate the key. The proposed approach is demonstrated a high calculation speed when using quantum computing.

Demands for geriatric hospital have increased in an era of rapidly aging population. Most of aged patients tend to stay in institutions for long terms. This means that the patient rooms of geriatric hospital should be given different considerations from those of normal hospital in designing interior features. They should be a homelike places for the aged patients and designed to take care of specific needs of the aged. However, most of geriatric hospitals are designed with little attention to such point. They appear almost same to normal ones. This study attempts to examine how users evaluate patients' rooms. The users are nurses, care-givers and family members of aged patients in six geriatric hospitals in Busan. They rated 12 features of patient rooms from 0 point to 100 points and described reasons why they rated in that way. Also, the walk-through was done for these six hospitals. 12 features are sizes of patient rooms, sizes and fixtures of bathrooms, sizes and locations of windows, bed layout, numbers and types of chairs, sizes and types of closet, lighting, color scheme, finishes of floor and wall, and interior design tone. Followings are findings : The users evaluated patients' rooms relatively positive. However, extra chairs for visitors, closet in patients rooms and storage in bathroom, and sizes of patients rooms and bathrooms were evaluated relatively negative.

The twenty seven houses at Incheon city, were remodeled in 2009 for the physically handicapped people. This research had been done the analysis of the itemized questionnaire by the needs of the physically handicapped for their better living environment and suggested the following remodeling devices. First of all, there was the priority for the remodeling of their living facilities. According to their priority, they wanted to remodel their bathroom, kitchen & dining room, veranda, living room, and hall way. These were based on their needs of movement, personal hygiene, convenient closet, and cabinet usage. In particular, their demands were shown as followings. The wheelchair using handicapped people required safe doorknobs, unslippery floor materials, removal of step levels, and heights adjustable washing stand for their bathroom. They also requested washboard, non-threshold, and automatic door locks. Otherwise, the disabled in critical condition who could not move anything preferred the remodeling of inner structure of living spaces and automatic door system. The slight disabled and the families those who have the disabled demanded the remodeling of kitchen & dining room, and preferred the reorganization of closet, cabinets, floor tiles, and turncock. The remodeling of bedroom was mostly requested by the disabled women, people with the brain disorder, and disabled people in critical condition who could not move anything. They wanted the remote controlled lightings.

"Brokeback Mountain" deals with the love story between two homosexuals named Ennis and Jack. They never do use the word 'homosexual' but instead 'love.' They hide their love into the closet. And they conform to socially constructed gender roles. It is because they recognize that social order has punished the homosexuals severely through history. Especially, Ennis fears the homophobic heterosexual gaze. Through his paranoia, this article examines the conventional contradictory social order causing by the tragic story that is the homosexual "closet phenomenon." Such a phenomenon has resulted from the traditional patriarchal family system that is the central unit of society. Conventionally, patriarchy consists of a dominant male and non-dominant female system, based on force. Sexuality has been constructed, experienced, and understood in culturally and historically specific ways. Homosexuality has been imaged conventionally as a female disguised as a man. As such, homosexuality would violate and break such a constructed system that keeps the sexual hierarchy through male dominant construction. As homosexual, ironically with macho gender personas, Ennis and Jack are social outsiders. Through this story, Proulx suggests the conventional fixed social order is contradictory and, therefore forces the readers to re-consider the world and ponder about the future.

Fashion stress is a pertinent aspect of modern consumer culture that has been underexplored in academic research. This study developed a conceptual framework of fashion stress and a multidimensional scale to measure consumers' fashion stress. The qualitative study included literature reviews on consumption stress, shopping stress, and consumer behavior, as well as focus group interviews to gain insight into various dimensions of fashion stress. NVivo 12.0 was used to analyze the qualitative data and identify core categories following the grounded theory methodology. The quantitative study involved a preliminary and a primary surveys to verify the validity and reliability of the fashion stress scale. A total of 220 questionnaires were used for data analysis. The results show that fashion stress consists of eight factors: care, shopping, fit, brand, financial, closet, style, and disposal. Choice difficulty plays a significant role in all factors of fashion stress. Moreover, shopping stress had a negative impact on impulse buying, while other factors such as fit, brand, closet, and disposal stress had a positive impact on impulse buying. Thus, fashion stress is a potential antecedent of impulsive consumer behavior. The results also confirm the validity and reliability of the scale. The fashion stress scale developed in this study offers researchers a valuable tool for assessing and understanding consumer experiences.

According to cultural diffusion route, the Korean toilet culture could be classified as southern culture and northern culture, In Cheju Island the toilet is located on the stone fence of swine. The native people of Cheju Island name it as TONGSHI. And Southern culture could be diffused from South Sea to Cheju Island by the sea current. Around Mt.Chiri area, the greater part of traditional toilets are on the upper floor in the barn, and pigs are on the bottom floor under the toilet. This type of toilet would be the northern culture of the toilet, which would be diffused from continent of Asia to Korean Peninsula. Residents of these areas also name this toilet as TONGSHI. The Korean word "TONGSHI" means a toilet on the pig fence. Traditional toilet culture in Korea differs from regions and residents. We can find dry-closets in Seon-am Temple and Song-kawng Temple. This high floor dry-closet type would be effected by Buddhism. In the reclaimed land and islands of west sea we could not find the old traditional toilets.l toilets.

It appraises that use an indoor noise standard, a NC value which is a noise appraisal, a dB(A) value, a N value in foreign country because it doesn't yet ready an appraisal standard in domestic. Also, It appraises that the supply and drainage noise which could change water supply pressure, $4kg/cm^2,\;3kg/cm^2,\;2kg/cm^2,\;1.5kg/cm^2,\;1kg/cm^2$, bring about a noise and inquires how does noise level indicates according to each instruments. In case of a water supply pressure standard, $3kg/cm^2$, a C-605is $3{\sim}5dB(A)$ lower than another instruments in directly overhead stories. It appears that all of them is similar to level in directly under level except c-407(2)Analyzed the NC value, c-605is the lowest level, NC-50, of a water supply pressure, $4.0kg/cm^2$, c-407 is the highest level, NC-55.(3) In case of N value, which is one of water supply methods in Japan, it is the lowest level, N-55, of a water supply pressure, $4.0kg/cm^2$ same as NC value and C-407is the highest level, N-60.(4) In case of water supply that is likely to noise level, It appears 6dB(A) level gap each instruments, and C-605 is the lowest level, 63.9dB(A).
