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.

This study surveyed 266 housewives residing in a Gyeonggi-provincial area for their dietary attitudes, dietary habits, nutrition knowledge, and application of nutrition information to daily life according to whether they use nutrition labeling. The survey on the dietary attitudes of the subjects showed that the points of "think that nutrition affects health", "quite interested in nutrition and health information", "like developing and trying new diverse recipes", and "persistently try new foods" were higher among those who check out nutrition labeling (Check group, n=112) than those who do not check out nutrition labeling (No check group, n=154). Reason for snacking, the Check group reported higher in the reasons of "for taking nutrients" but lower in the reasons of "do not eat enough meal" and "impulsively" than the No check group (p<0.01). Asked about why they check the nutrition labeling, the Check group answered "to compare products with each other" and "to purchase healthy food" whereas the No check group said "to decide whether the food is safe or not" and "to reduce body weight" (p<0.01). The Check group showed more recognition on the significance of the nutrition labeling and application to their actual daily lives than the No check group. Therefore, our results suggest that proper use of nutrition labeling is expected to improve dietary attitudes and dietary habits as well as enhance the application of nutrition information to actual daily life and promote health not only for the housewives but also for their family members as well.

Various interpretations on the boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system, and on the geologic structure and stratigraphy of the $Okch{\check{o}}n$ system have been yielded by the previous studies, and they are still in hot debate. The present work has mainly studied on the boundary between the $Okch{\check{o}}n$ and $Chos{\check{o}}n$ systems in the south of $Jech{\check{o}}n$, and the geology in its vicinity to clarify the previous misinterpretations if any on the geologic structure and in trun stratigraphy of the area concerned. The boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system has been thought to be (1) gradational relation which means two systems are the same formation, (2) unconformable relation in which the $Okch{\check{o}}n$ system overlies the $Chos{\check{o}}n$ system, (3) unconformable relation in which the $Chos{\check{o}}n$ system overlies the Okchon system indicating that the age of the $Okch{\check{o}}n$ system is Precambrian, and (4) fault contact in which the $Okch{\check{o}}n$ system of Precambrian age comes in contact with the $Chos{\check{o}}n$ system of Cambro-Ordovician age. The present study clearly found that the relationship between the two systems is a fault zone contact. Shear zone of a width of 300 to 400m is developed, and andesitic volcanics and basic dikes are intruded along the fault zone. This fault contact is exactly the north extension of the Bonghwajae fault, which was denominated long time ago by two of the present authors. The eastern side of the fault has been uplifted so that the $S{\check{o}}changri$ formation of the $Okch{\check{o}}n$ system cropped out in the zone of the Great Limestone series. All the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, but the present study found an overthrust having a strike of $N8^{\circ}E$ and dip of $30^{\circ}NW$ between them, and the $S{\check{o}}changri$ formation has thrusted over the Great Limestone series at the central part of the study area. In the southern and northern parts of this uplifted $S{\check{o}}changri$ formation, the Great Limestone series rests unconformably on it. In the eastern part of the study area where the Mt. Dangdu is located and the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, Precambrian basement rock whose age is older than 1720+50 m.y. crops out in the northern part of the east-west trending high angle fault, and the Great Limestone series rests unconformably on the basement.

This study was intended to inquire into Check Pattern. The purpose of this study attempted to make a systematic investigation of the characteristic of the Check Pattern, the checker using vertical and horizontal lines which was the universal plastic element and inquire into it in terms of era, designers and combined work. By doing so, this study attempted to Investigate the phase of the Check Pattern in world fashion and further forecast the future of checker design applicable to the 21th century fashion. The result can be summarized as follows : 1. Mondrim's neo-plasticism has not only had a great influence on Op Art and Minimalism work but is deeply related to fashion and textile design. Mondrian used vertical and horizontal line ad the dualistic element. 2. The checker is estimated to have been used since the Etruian times, though uncertain. and largely divided into the Madras check and Scotland Check. Though the origin of the tartan representation of the Scotland check can not be accurately found out, it began to emerge in around the 13th century. 3. Check Pattern has began to be widely used with the development of the textile industry since 1826 and been used in every typical Sihoutto appearing in each era up to the present. And Check Pattern is used most designer in the world, who represent their own personality in their works. This study could find out that the checker is the element of Infinite applicability in the future. It is expected that the sophisticated and beautiful design using the chocker will be presented by many korean designer though the overall and systematic study of the checker.

Twenty - four elite mulberry germplasm each of indigenous and exotics were studied for their leaf yield and compared with commercial check ($V_1$ and Kosen). Accession MI-0416 and ME-0169 out yielded the check accession in leaf yield/plant. The other few mulberry germplasm were also performed at par with the checks. For quality test and bioassay were conducted with the leaves of selected mulberry germplasm. Among the selected twelve mulberry accessions used for bioassay, MI-0376 and ME-033 performed better than check ($V_1$, Kosen). Other mulberry accessions i.e., MI-0310 and MI-0437 are on par with the check as far as the bioassay is concerned. MI-0376 and ME-0033 out yielded in rearing parameters and qualified for 11 and 10 rearing and related traits. Other mulberry accessions i.e., MI-0310 and MI-0437 were also qualified for eight rearing traits along with check ($V_1$). The mulberry accessions tested after selection from the preliminary characterization seems to be better and equally good in rearing and leaf yield compared to check ($V_1$, Kosen), which provides scope for selection and further evaluation. The selected mulberry accession may be included in crop improvement programme.

Check valve failure is one of the worst problems in nuclear power plants. Recently, many researches have been based on new technology using accelerometers and ultrasonic and magnetic flux detection have been carried out. Here, we have suggested a method that uses acoustic emission sensors for detecting the failures of check valves through measuring and analyzing backward leakage flow, a system that works without disassembling the check valve. For validating the suggested acoustic emission sensor methodology, we designed a hydraulic test loop with a check valve. We have assumed in this study that check valve failure is caused by disk wear or by the insertion of a foreign object. In addition, we have developed diagnostic algorithms by using a neural network model to identify the type and size of the failure in the check valve. Our results show that the proposed diagnostic algorithm with acoustic emission sensors is a good solution for identifying check valve failure without necessitating any disassembly work.

In this study, we investigated methods of quality check for digital basemaps and proposed effective methods of quality check. We used new statistical methods for quality control in order to carry out quality check for digital basemaps. We proposed 2-stage complete sampling and 2-stage cluster sampling method to improve present statistical methods of quality check(1-stage complete sampling method). We estimated error rate and number of omitted objects using simulated data about all delivered digital basemaps and estimated variances about it. We could determine confidence interval about error rate and number of omitted objects.
