A significant body of information systems research is concerned with user participation as a means to improve user satisfaction within systems development. In spite of the many studies in this area, findings are not consistent or cumulative. One of the reasons for this is not to be considered the type of systems. Most research are focusing on traditional system development under the mainframe environment instead of under end-user based environment like web-based information system or ERP. End-user based environment requires user's strong initiatives in the system development life cycle. It means the user\`s simple participation is not enough and user-led-development is more appropriate for the system success. This paper can call this new concept is end-user joint work which means user has to participate in the system development as a co-developer. This paper investigates how the end-user joint work contributes end-user satisfaction and two variables in particular-job complexity and technical competence-moderate the outcomes of end-user joint work Analysis of 112 independent systems development projects indicated that end-user joint work has a direct relationship with end-user satisfaction. In addition, the two variables were found to moderate key roles on this relationship. That is, the strength of this relationship depended on the level of these factors.

This study looks into the appearances and contents of undercloths advertisements by analyzing them appeared in women\`s magazines of Korea, which are , and published between 1965 and 1999 mainly targeting the women at the age of 20s through 40s. This study leads to the following conclusions : 1. Most of advertisements use 1 or 2 pages of the magazines with colored pictures. 2. The most frequently advertised underclothes is brassieres and white and pastel are dominant colors. Also, spandex and cotton are the most frequently appeared fabrics in the advertisement. 3. Professional Korean female models in twenties are the most favored choice for those underclothes advertisements and those models dominantly face their fore part with showing the body parts higher than their knees. Solo model appear in most of the advertisements and independent appearance is dominant. 4. In the visual expression of the advertisements explicitly show the products for visual expression, whereas verbal expressions mostly emphasize the benefits to be obtained from the underclothes advertised. 5. Advertisement appeals are mainly base on readers\` reason rather than sensibility.

Various personalized services are provided based on user context these days, and IoT(Internet of Things) devices provides effective ways to collect user context. For example, user's activity such as walking steps, calories, and sleeping hours can be collected using smart activity tracker. Smart scale can sense change of user's weight or body fat percentage. However, these services are independent to each other and not easy to make them collaborate. Many standard bodies are working on the documents for this issue, but due to diversity of IoT use case scenarios, it seems that multiple IoT technologies co-exist for the time being. This paper propose a framework to collaborate heterogeneous IoT services. The proposed framework provides methods to build application for heterogeneous IoT devices and user context management in more intuitive way using HTTP. To improve compatibility and usability, gathered user contexts are based on MPEG-UD. Implementation of framework and service with real-world devices are also presented.

Purpose: This study, using a pre-posttest design of non-equivalence comparative groups, was done to determine effects of KC (kangaroo care) on weight and SH (stress hormone) of premature infants. Method: Participants were 31 premature infants assigned to KC(14) or CG(control group)(17). Data were collected from June 2006 to February 2007. KC was given for 60 minutes at a time, Mon, Wed, and Fri for a 10 times. Body weight was measured at a fixed time daily and serum cortisol was examined as part of routine blood testing, frequent for premature infants. Results: The weight for infants in the KC group was higher than the control. The difference was significant between both the two groups, and the 2 measurement times(F=12.7, p=.001). SH(cortisol) in infants of KC group decreased than CG, but there was no valid difference from the statistical viewpoint. Conclusion: The result of the study suggest that KC contributes to weight increase in premature infants and also that KC is effective for SH reduction in spite of the lack of statistical validity. Therefore, our conclusion is that KC can be used as an independent nursing intervention for development and advance of premature infants.

Interactions such as mergers and flybys play a fundamental role in shaping galaxy morphology. We used the Horizon Run 4 cosmological N-body simulations to study the frequency and the type of halo interactions as a function of the environment, the separation p, the mass ratio q, and the target halo mass. We defined targets as haloes more massive than 10^11 Msun/h, and a target is interacting if it is located within the virial radius of a neighbour halo more massive than 0.4 times the target mass. We find that the interaction rate as a function of time has a universal shape for different halo mass and large-scale density, with an increase and saturation. Larger density yield steeper slopes and larger final interaction rates, while larger masses saturate later. Most interactions happen at large-scale density contrast ${\delta}$ about 10^3, regardless of the redshift. We also report the existence of two modes of interactions in the (p,q) plane, reflecting the nature (satellite or main halo) of the target halo. These two trends strongly evolve with redshift, target mass, and large-scale density. Interacting pairs have similar spins parameters and aligned spins, with radial trajectories, and prograde encounters for non-radial trajectories. The satellite trajectories become less and less radial as time proceed. This effect is stronger for higher-mass target, but independent of the large-scale density.

The static tensile tests of GFRP, ID300, CFRID300 and CFRPEEK were made on the plain and notched specimens at room temperature. The results were discussed based on linear notch mechanics which was proposed by H.Nistani. The fracture of notched GFRP, ID300, CFRID300 and CFRPEEK specimens is controlled by the elastic maximum stress, $({\sigma}_max)$, and the notch root racius,$\rho$, alone, independently of the other geometrical conditions. The relation between fracture nominal stress,$({\sigma}_max)$, and stress concentration factor, $K_t$ and a part where $({\sigma}_c)$ is nearly constant independent of $K_t$. A similar phenomenon can be seen in the fatigue tests of notched specimes under rotating bending or push-pull. The almost constant $({\sigma}_c)$ values correspond to the nearly constant apparent stress intensity factor, $K_{1pc}$ values, obtained by assuming ,$\rho$=0. This can be attributed to the existence of the stable crack. Linear notch mechanics is very useful for analyzing the static tensile fracture behavior of notched GFRP, ID300, CFRPEEK specimens.

Various current events provide evidence that society is undergoing changes in perceptions of social relationships. Specifically, visual media in the form of advertisements can convey images which reflect society's values and concepts about role relationships. The purpose of this research was to examine ads in fashion magazines to determine what types of model roles and role relationships typically appear in fashion advertising which can mirror society's values. A content analysis was conducted of ads obtained from US Vogue and US GQ for the year 2002. Six kinds of roles/relationships were found: (1) Narcissism (representing self absorption), (2) sexually enticing opposite-sex relationships, (3) close/romantic same-sex relationships, (4) friend relationships, (5) family relationships, and (6) independent relationships. Of these, narcissism predominated, however, a small number of sexually provocative ads appeared as well as same-sex romantic relationships. Because sole (single) models were more typical, they also were examined to determine ways in which they relate to the audience. Characteristics examined included body presentation & pose, eye gaze, and facial expression. Direct eye gaze was the typical way to engage the audience. Gender differences were apparent: smiling was more typical of women, indifference for men. The symbolic meaning and values investigated from this research are the blurring of gender identity portrayed in homosexual imagery, family values, and the value of youth. The consistency of models' race in ads does not portray the diversity reflected in the demographic census.

We present our study on a comparison of dark matter halo merger history from the runs using different numerical simulation codes. To analyze the uncertainty caused by the use of different N-body calculation methods, we compare the results from two cosmological hydrodynamic simulation codes GADGET-2 and RAMSES, which use a TreePM algorithm and the Adaptive Mesh Refinement(AMR) technique respectively. We perform cosmological dark matter-only simulations with the same parameter set and initial condition for both. The dark matter halo mass functions from two simulation runs correspond well with each other, except for lower mass haloes. The discrepancy on the low-mass haloes in turn causes a notable difference in halo merger rate, especially for the case of extremely minor merger. The result from GADGET-2 predicts that most haloes undergo more number of mergers with small haloes than that from RAMSES, independent of halo mass and environment. However, in the context of the study on galaxy evolution, such extreme minor mergers generally do not have strong effects on galaxy properties such as morphology or star formation history. Hence, we suggest that this uncertainty could be quantitatively negligible, and the results from two simulations are reliable even with only minor difference in merger history.

The neck is the human body is closely con-nected with the life and properties of keeping warm as one of the opening part in clothes. In ancient times it was put on necklace for the protection of neck and in Rome it was worn muffler called focale for the protection of neck throat. in addition cravat directly originated in necktie today was primarily worn for the protection of soldier's neck and has been turned into decorative purpose until today. As the ornament is developed to vari-ous kinds of form the neck decoration is changed and grown again and again. Therefore this thesis studies history of the neckwear and various the symbolic factor. The first factor is the social. The neckwear shows the social position class and status and does social mutual interaction as conversation starters. The second factor is the mental It express individuality fondness attitude and is felt to be indignity by being forced to be worn. The third factor is the political. it shows political tendency by indicating the royal sign or part's sign in necktie like the French royal-ist's green muffler The forth factor is the man's sexual. I expresses wearing stock being brave symbol-izing independence. The sixth factor is the traditional. It is worn with appearing traditionand custom and one of cultural movements. The seventh factor is the ideological. It symbolizes the freedom of suffragettes and emancipation of woman. The social factor is the most extensive among them. The neckwear is various in the way of expression like its kinds and is generalized, It functions as a independent part of clothes.
