Domestic construction industry (including plant engineering industry) faces severe competition with world-wide leading companies under WTO (World Trade Organization) system. To survive in this competition, domestic construction company should establish and operate standardization system efficiently. In this paper, check list is presented to prepare the efficient reliability management system in domestic construction. And then, the check list is applied in MIR(Maturity Index on Reliability) estimation item to estimate reliability management level of company quantitatively.

Recently CCTV system is installed widely purpose to enhanced physical security, gathering criminal evidence and management of facilities. In spite of supporting strong management function, CCTV system has weak security function. Therefore high security management function is required. Generally it's not easy to control the devices under NAT using a NMS(Network Management System). So we design and implement alive check algorithm of CCTV devices under NAT using DVRNS address resolution and TCP session check. We evaluated and analyzed of developed system on real environment which includes about 100 DVRs under NAT. As a result of test, it showed that device alive check and DVRNS address resolution were well performed without any error.

The purpose of this study. was to Identification the Risk of construction method to protect and reduce the risk of construction period. The inspection list usually has the difference of importance because this list is not made by Method which is not focused on Method. We tested Risk occurring frequency and it's strength by checking the level of Risk. To solve and compensate the matter which happened by changing the each Method Check List to each General Inspection List, we added the each Method Check List by checking the importance of check list of each process. By doing this, the Check List for finding Risk level of Method was created by using the check list of each Method.

In this study, focusing on work types of lifting modules and modules assembly in modular construction sites, unit works were defined according to the construction process of each work type, and safety management elements, safety management activities, and key check point were proposed. The results of this study may have somewhat overlapping contents in the construction procedure in order to derive specific safety management activities and check point for each unit work. Therefore, there is a limit to use the results in an actual modular construction site. In future research, we plan to improve this part and derive a checklist that considers field usability.

The issue of hotel energy use is growing more significant as the hotel industry expands. It is important to take into account the electrical installation and space-specific features in a room unit in order to comprehend the energy consumption of a hotel guestroom. In light of this, this study aimed to analyze standby power for enhancing the energy efficiency of a hotel guestroom during check-out status. This study was conducted in three steps: (i) data collection; (ii) analysis of energy consumption patterns; and (iii) analysis of energy efficiency improvement plan. The main findings of this study can be summarized as follows. First, 32.24% of energy was used in fan coil unit) during check-out status. Second, a hotel guestroom had a 4.30% energy saving potential, based on energy consumption patterns during check-out status. This study can contribute to support hotel management to operate guestrooms differently by helping them identify patterns in energy use and realize potential savings.

There is no standard model for a Stated Period Check and a Precise Safety Diagnosis to remove electric fire and shock in the university Lab and institute. Especially, the research for the Stated Period Check and the Precise Safety Diagnosis of the Lab related to electrical field is very weak currently, and it is very necessary to build a detail safety plan. This paper informs the specific standard guideline of the safety check list, method and equipment and it shows the way to evaluate safety grade too. This paper also provides the information of R&D process through the analysis of electrical safety check list of ordinary R&D Lab. It shows a new detail guideline to R&D Lab, and the new guideline removes existing problem and deliver the effective standard model to each R&D Lab. The standard model developed in this research adopts the clear guideline of each check list for the electrical environment of current R&D Lab. This standard model can be applied for every R&D Lab to detect routine safety check and detail safety check immediately. This Research will generally improve not only the effective safety check, but also the safety level for R&D Lab to prevent the electrical accidents.

In this article, the organizational structures of check- in and claim function are examined. The procedure and function of serials control system(CLASSMATE, EBSCONET, LINX, NOTIS, INNOVACQ) are analyzed, particularly in check- in and claim system. A check-in and claim system is suggested through analysis of above serials control systems.

In western, aromatherapy uses essential oils to prevent and treat disease, and is one of the ways to stay healthy. In oriental medicine, there was also a similar medical treatment using aromatic herbs for a long ago. The exisiting research of oriental medical herbs is mainly focused on the theory of qi and flavor(氣味論). But on aromatherapy used with aromatic herbs, it is necessary to study the aromatic herbs by aroma. So "xi$\bar{a}$ng p$\check{u}$, 香譜" and "b$\check{e}$n c$\check{a}$o g$\bar{a}$ng m$\grave{u}$, 本草綱目" mainly contain the study about clinical effects of aromatic herbs. And "b$\check{e}$n c$\check{a}$o p$\check{i}$n hu$\grave{i}$ j$\bar{i}$ng y$\grave{a}$o, 本草品彙精要"mainly explains the effects of medical herbs with five aroma classification of x$\bar{i}$ng(腥), sh$\bar{a}$n(膻), xi$\bar{a}$ng(香), ch$\grave{o}$u(臭), xi$\check{u}$(朽). The former one makes more clinical uses of medical herbs, and the latter one grows up the theory of medical herbs. This study is expected to have a good influence on aromatherapy and classification of oriental medical herbs.

Low density parity check (LDPC) code is widely used, since it shows superior performance close to Shannon limit and its decoding complexity is lower than turbo code. Recently, it is used as a channel code to decode Wyner-Ziv frames in distributed video coding (DVC) system. In this paper, we propose an efficient method to design the parity check matrix H of LDPC codes. In order to apply LDPC code to DVC system, the LDPC code should have rate compatibility. Thus, we also propose a method to merge check nodes of LDPC code to attain the rate compatibility. LDPC code is designed using ACE algorithm and check nodes are merged for a given code rate to maximize the error correction capability. The performance of the designed LDPC code is analyzed extensively by computer simulations.

Damage such as landslides has been caused by natural phenomenon like a heavy rain. As appropriate countermeasures, rather than analysing the cause of the landslide, we used methods of check dam installation and maintenance mountain basin. A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. In this study, we analysed the adequacy of check dam built to prevent further damage after landslides through GIS and examined the sediment erosion in the existing check dams for an ideal location of check dam, considering the accessibility and size. As a result of reviewing soil loss in the study watershed according to RUSLE(Revised Universal Soil Loss Equation), the basin I had about 2% soil loss reduction, the basin II showed less than 1 % soul loss reduction, and basin III showed the reducing effect of 5 % soil erosion.
