In this research, I finally came to a conclusion analyzing the connection among managing of each items in management expenses, the size of each complex and stories, and the term of using. (1) In the managing cost regarding to the management manner, although the managing cost of self-governing management is less imposed than the one of commission management, there is slight difference between those Costs. And it is more important to consider the effectiveness of management than to emphasize reduction of management cost. (2) The higher the stories, the higher the managing cost of elevator per the unit area. It Is caused by the fact that the father the distance of the elevator operating, the higher the electric charges. (3) The third of one of total management cost goes to pay the personnel expenses. So I found that the effective management of the expenses is available to reduce management cost. (4) The higher the stones, the lower the cost of personnel expenses including the cleaner cost. (5) The sum of costs assigned in repairment and management increases in proportion to the term of using. The costs assigned in special repairment and management are interacting to each other. (6) To reduce the management cost, we have to cut down the personnel in security guard that occupies one third of total management cost with application to the joint security system and operation of the self-governing guard. Through this process, it will be easy to accomplish the rationalization of contract with an outside order. Because the improvement of management service is not only the responsibility of owner but also the one of dwellers. And it Is imperative to realize the importance of cooperation and trust between the owner and dwellers. And the establishment of effective managing system which has convenience and rationality must be settled without delay.

The purpose of this study was to investigate service support programs for the work-family balance in the community. Service support programs in the community are at beginning stages of development, because it has taken about 10 years to put a self-governing system into practice in Korea. This study concentrates on service support programs developed by various service organizations in the city and does not include any rural districts. First, the developmental process of the work-family balance model and type of the service support program in the community were studied. Next, the situation of care service support was examined based on written articles. Finally, a few suggestions were made f3r work-family balance in the community. The developmental situation of work-flmily balance in Korea is in a stage which is shifting from the company-leading model to a family-company-community model. The most common type of service support program offered in the community until now has been the informal sector through relatives, neighbors or friends. However, service support programs, in the public sector by the government and in the voluntary sector by nonprofit organizations and corporations, has rapidly been growing and the number of services from each sector has also increased. Profit organizations in the private sector, such as medical and care service centers, are also now rapidly increasing. It appears that service support programs contributing to the work-family balance in the community come from a number of sectors, including public, voluntary, private and informal sectors, to suit consumer needs.

BACKGROUND: The Geomunoreum Lava Tube System (GLTS) is both vast and culturally valuable. The Jeju Volcanic Island and Lava Tubes, which are partly composed of the GLTS, have been declared as a United Nations Educational, Scientific, and Cultural Organization (UNESCO) World Heritage Site. Exploration of the caves is strictly regulated to conserve these vulnerable environments. Photographs provide limited information and do not describe the entire environment comprehensively. Therefore, we created several illustrations of the lava tubes to display their environmental features. METHODS AND RESULTS: We explored six lava caves (upstream and downstream) in the GLTS and photographed their geological features and yellow walls, the colors of which are influenced by microbial mats. We compared the hex codes of the wall colors using the Clip Studio v1.10.5 software and created illustrations that accurately represent the scale and features of the caves. CONCLUSION(S): Upstream and downstream caves of the GLTS differ in scale and volcanic features. We illustrated various characteristics of the caves including lava cave features, vegetation, and microbial mats. We also described the internal and external cave environments.

In accordance with the Carbon-Free Island by 2030 policy of Jeju Special Self-Governing Province, renewable energy sources are increasing in Jejudo Island. Due to the intermittent output characteristics of wind turbines, one of the renewable energy sources, which can cause unbalanced system conditions between the demand load and the power generation of Jejudo Island. The Korea Power Exchange limits the output of wind turbines for stabilizing the Jeju power system. Therefore, this paper proposes a method to supply a limited output of Sangmyeong Wind Farm in Jeju Power system to Energy Storage System(ESS) and Water Electrolysis Device(WED). The voltage and frequency fluctuation of the Jeju power system is checked accordingly. The simulation results are performed using the PSCAD/EMTDC program.

The spontaneous self-organization of amphiphilic molecules into complex aggregates was undoubtedly an important factor in the emergence of life on earth. We study the parameters governing the self-organization of a simple amphiphilic model system using electron cryomicroscopy of ice-embedded specimens in combination with extensive data analysis. Different stable helices can be generated reproducibly by changing the parameters controlling the molecular aggregation process. The repeating units of the helical aggregates in the micrographs can be found by multivariate statistical image analysis techniques, and these two-dimensional projection images suffice for calculating the three-dimensional density distribution of the fibers. We present a typical structure consisting of a narrow stack of compartmented bilayers twisted into a left-handed helix. Our new techniques directly elucidate the three-dimensional structure of helical assemblies, and can complement or replace diffraction-based approaches.

This paper presents the formulation of a new bridge-vehicle system with validation using the field data. Both pitching and twisting modes of the vehicle are considered in the contribution of the dynamic effects in the bridge responses. A heavy vehicle was hired as a control vehicle with known axle weight, axle spacing and spring coefficients. The measured responses were generated from the control vehicle running at a particular speed at a test span at Ma Tau Wai Flyover. The measured responses were acquired using strain gauges installed beneath the girder beams of the test bridge. The simulated responses were generated using BRVEAN that is a self-developed program based on the proposed bridge-vehicle system. The validation shows that the bridge model is valid for representing the test bridge and the governing equations are valid for representing the motion of moving vehicles.

The objective of this paper is setting out, for a cable-stayed bridge with a curtain suspension, a method to determine the modes of vibration of the structure. The system of differential equations governing the vibrations of the bridge, derived by means of a variational formulation in a nonlinear field, is reported in Appendix C. The whole analysis results from the application of Hamilton's principle, using the expressions of potential and kinetic energies and of the virtual work made by viscous damping forces of the various parts of the bridge (Monaco and Fiore 2003). This paper focuses on the equation concerning the transversal motion of the girder of the cable-stayed bridge and in particular on its final form obtained, restrictedly to the linear case, neglecting some quantities affecting the solution in a non-remarkable way. In the hypotheses of normal mode of vibration and of steady-state, we propose the resolution of this equation by a particular method based on a numerical approach. Respecting the boundary conditions, we derive, for each mode of vibration, the corresponding frequency, both natural and damped, the shape-function of the girder axis and the exponential function governing the variability of motion amplitude in time. Finally the results so obtained are compared with those deriving from the dynamic analysis performed by a finite elements calculation program.
