This paper is a part of “The Study of the Traditional Korean Ethenic Farmhousing in Yanbian, China”. The purpose of this study is to identify reception behavior and places for guests of the traditional farmhouse. In this study, a survey using questionnaire was conducted in which one hundred and twenty four farmhouses were analyzed thoroughly. The major findings are as follows : 1) Most frequent guest receptions among Dallejae residents are casual meetings of relatives and non-relatives, husbands' birthday parties, one-year birthday Parties of children, wedding receptions, and Whankap (sixtieth birthday party). 2) They receive guests and serve them at Chung-ji-kan and Oot-bang. 3) Reception behavior has undergone change along with social, political, and economical changes. They receive guests with much more hospitalities than before. Only memorial services are simplified compared to the past.

Hypertonicity (hypernatremia) of extracellular fluid causes water movement out of cells, while hypotonicity(hyponatremia) causes water movement into cells, resulting in cellular shrinkage or cellular swelling, respectively. In most part of the body, the osmolality of extracellular fluid is maintained within narrow range($285-295 mOsm/kgH_2O$) and some deviations from this range are not problematic in most tissue of the body except brain. On the other hand, the osmolality in the human renal medulla fluctuates between 50 and $1,200 mOsm/kgH_2O$ in the process of urine dilution and concentration. The adaptation of renal medullary cells to the wide fluctuations in extracellular tonicity is crucial for the cell survival. This review will summarize the mechanisms of urine concentration and the adaptation of renal medullary cells to the hyper tonicity, which is mediated by TonEBP transcription factor and its target gene products(UT-A1 urea transporter etc.).

The market in the 21st century has drastically changed due to the advances of digital technology. This could be represented by the key words prosumer, do-it-yourself, mass customization, and so on. The net generation is in the center of change and nowadays teenage groups wearing school uniforms is a part of this generation. Therefore the current school uniform hardly fits their tastes and demands. This study aims to provide the fundamental information for developing the school uniforms for the net generation based on the study of the characteristic of net generation and questionnaires targeted at high school students regarding the current school uniform.

The current study was conducted to evaluate the lifespan extension effects of leonurine and its synthetic fragmental analogs using Caenohabditis elegans model system. Leonurine significantly prolonged the lifespan of C. elegans in a dose-dependent manner. To dissect the structure-activity relationship between leonurine and lifespan extension activity, seven novel fragmental analogs were synthesized and evaluated. Our study revealed that benzoate part of leonurine is responsible for its lifespan extension property rather than quanidine moiety.

The benefits of hydroforming technology are known as weight and cost savings through part consolidation and reduced post-forming processes such as welding and piercing. Hydroforming technology has some weaknesses in terms of process cycle times. But, as the hydraulic system and process designs are continuously developed, the cycle time is also reduced to acceptable and competitive levels. Hot air bulging is one of recently developed hydroforming techniques. Hot air bulging in order to further extend the forming degrees of Al lightweight material is investigated. A heated tube is placed in a heated die and sealed at the ends by sealing cylinders. The tube is subsequently expanded against the die cavity wall by internal pressure provided by air medium. The result of this study shows that axial feeding speed and air pressure have an effect on formability of Al air bulging at elevated temperature.

As part of the DIGIT key program, we observed GSS30-IRS1, a Class I object located in Ophiuchus (d=125 pc), with Herschel-PACS. More than 70 lines were detected: CO lines of $J=14{\rightarrow}13$ to $41{\rightarrow}40$, several $H_2O$ lines of Eu=100 to 1500 K, 16 OH lines, and two atomic [OI] lines at 63 and 145 ${\mu}m$. All lines, except for [OI], were detected only at the central spaxel of $9.4^{\prime\prime}{\times}9.4^{\prime\prime}$ while the [OI] emission is extended along the NE-SW direction. One interesting feature in GSS30-IRS1 is that the continuum is extended beyond PSF, unlike the line emission. For detail analysis, we apply the non-LTE LVG model, RADEX as well as simple rotational diagrams to the detected line fluxes. We will discuss about the physical conditions around GSS30-IRS1, learned by the line flux analysis.

This paper studies the estimation of hazard parameters, which have a close relation with product reliability characteristics in reliability test. Among the many kinds of estimation methods, hazard Probability Paper(HPP) is commonly used. The HPP is very convenient, but it has a great disadvantage in estimation W by plotting method It is very difficult to get the same results even if one use the same data several times. A computer program for the regression method is used for the parameter estimation to reduce these errors. Especially, the computer graphic program was written in GW-BASIC 3.22 language and a couple of running examples for user's reference appears in the appendix part.

The safety of staff customers and of general Public in general viewed as one of the most important requirements in the urban transit. The maintenance CALS system for car of urban transit is a part of standardization and development of urban transit system, and We have been performed the establishment of maintenance CALS system from 2001 to 2005. The RAMS for management computerization system are utilized in a variety of CALS system for user's convenience and safety in maintenance. Ever since its inception though, the urban transit has searched for ways to improve reliability, availability, maintainability and safety of the railway subsystem. In this paper, This system include RAMS(reliability, availability, maintainability and safety) of the vehicles shall be enhanced in the future.

This study concerned with the characteristics and causes of musculoskeletal disorders (MSDs) for employees aged 50 years or older. In order to do this, based on 8,011 accident analysis reports, we analyzed the differences of characteristics between groups under 50 years and 50 years or more in terms of gender, occupation, duration of employment, part of body, industry, size of business and work-related factors. Results show that the distributions of the injuries aged 50 years or older are statistically different from those of the injuries under 50 years. Also, older employees have high relationship between repetition, or contact stress/vibration and upper extremity MSDs. These findings can be used to develop more effective MSD prevention programs for older employees.

The purpose of this study is to examine the concept and experience of the elder mistreatment among the elderly. To achieve the purpose of this study, data were collected from 160 elders with family members through questionnaires. The major finding is that the concept on elder mistreatment of the old people is found for the most part psycological abuse or neglect. And, when the degree of family support about the elderly is high, the experience of the elder mistreament appears low. Therefore, family support may be higher to prevent elder mistreatment. Also, social support in the side economical, physical or emotional services may help to bring down the elder's disability contributing to the elder mistreatment.
