Numerical simulations were carried out for a fire in a clean room to confirm needs of a smoke control system and a sprinkler system, and to investigate a possible smoke spread-out. For a 1 MW methanol fire in a space of $39m{\times}13m$ floor and 4 m high, smoke spread-out was scrutinized for failure of the sprinkler system and/or the smoke control system. It was shown that the smoke control system removes smoke safely without the sprinkler system and that the sprinkler system is required to suppress smoke generation and spread of the fire, and to remove the smoke quickly. It was also confirmed that highly reliable sprinkler heads and automatic fire detection system are required for the sprinkler and smoke control systems.

In this paper, we propose a multiresolution progressive image transmission with spatial and bit-rate scalabilities using a $2{\times}2$ DCT. The multiresolition image represented by a $2{\times}2$ DCT is used for the progressive image transmission with spatial and bit-rate scalabilities. Because the proposed progressive image transmission method supports both spatial and bit-rate scalabilities, it can be adaptively applied to the receiver's scalability requests. We compare the proposed progressive transmission with that of the higher-order convolution-based Wavelet method. Comparisons show that the proposed method needs much less computations, but insignificant loss of image quality.

Background : The purpose of inner cannula is to protect the upper air way and permit air to pass freely, in addition, to provide endotracheal suction, artificial respiration and to maintain adequate oxygen saturation. The tube needs to be sterilized for maintenance and cleanness of air way and for prevention of bronchospasm. However, it has been reported that there is no guideline for sterilization and many hospitals conduct their own sterilization methods, for example, once a day(13's general hospital), three times a day(The Catholic University of Korea ST Mary's hospital) or even no cleansing. Consequently, the QI team of our hospital suggested the SOP(standard operating procedure) of sterilization and evaluate cost and time effect in nursing. Method : 1) Benchmarking of 13's neurosurgery department of general hospital in Seoul 2) Investigation of test records of sputum culture from patients with intubation for tracheotomy 3) Check of results of O2 Sat. monitoring to confirm of maintaining opened air way Result : 1) Improvement of process: decrease of excess sterilization of inner cannula (from 3 times a day to once a day) 2) Cost effects: saving over 10 million won per one year 3) Providing better nursing: time effects (30 min a day) permit to conduct more nursing activities Conclusion : It can get Cost and time effects in nursing with improved sterilization method of inner cannula. It needs to do research on improvement of the monthly exchange protocol of outer cannula and provide supporting data for the proper exchange schedule. The result of additional microorganism detection from patients with new process needs to be evaluated further more.

A high-speed directional interpolation algorithm based on the pattern of a $2{\times}2$ pixel block is proposed in this paper. The basic concept of the proposed algorithm is started from UDWT(un-decimated discrete wavelet transform), but there are no transform operations. In order to detect the direction of the edge, 4-pixel differences of two pairs in the $2{\times}2$ block are compared. The $2{\times}2$ block patterns are grouped into total 8 classes, and thereafter the directional interpolation is executed according to the type of the pattern. Since the calculation of the proposed algorithm is very simple and needs a few additions on integer data type, the computation time is almost same as that of bilinear interpolation algorithm. However, experimental results show that the output quality of the proposed one is better than those of the conventional interpolation ones in the objective quality and the computation time.

This study was conducted to identify and compare the needs of the integrated by local government, and to provide basic data for the provision of integrated care services. This is a secondary data analysis study using data from 10,299 elderly people living in 17 local governments who participated in the '2017 National Survey on the Aged People in Korea'. The difference in medical needs, daily living support needs, and social activity support needs were 2.4, 6.0, and 2.0 times higher in the highest regions than in the lowest regions. In addition, the size of the medical needs group, welfare needs group, and integrated care needs group varied by region. Through this study, it was confirmed that the level of integrated care needs varied by region. Therefore, in order to efficiently provide the services at the national level, it is necessary to accurately assess the needs of the aged in each local government, and accordingly, prioritize and identify available resources within the care service and appropriate allocation.

The proportion of the elderly in rural area(21.7％) is four times more than that of the urban area (5.4％) in Korea. With this rapid aging of the population in rural Korea there has been growing concern about the quality of life of rural elderly. Compare to urban elderly, rural elderly experience many disadvantages, especially in terms of limited offering of social/educational programs. Their social/educational needs are rarely assessed and there are few programs geared to the needs of rural elderly. In this regard, this study aims (1) to identify education and activity program needs of the rural elderly related to three dimensions: Family life, Farming life, and Community activities and (2) to develop education and activity programs for the rural elderly based on the needs assessment. For this purpose, data are gathered from 413 rural elderly and 110 community welfare specialists, using a structured questionaire. The statistical methods used for data analysis are descriptive statistics, cross tables with SPSS wins 10.0 program. The major findings of this study are as follows: Majority(94.1％) of the rural elderly wants to participate in diverse social/educational programs. They want to have programs dealing with 'relationship enhancement with children', 'nutrition', 'health and care', 'farming skill', 'gardening', 'volunteering', etc. Based on these results, we develop eight types of education program and four types of activity program, according to the priority of their needs in each dimension. There are four sessions of Family life program, and four sessions of Community activities program. The effect of these programs will be evaluated by taking pretest and protest in local basis.

Around 5.4 times writers representing China Journalism Guo Mo ruo Mao Dun and social needs of the times according to the spirit, according to their ideology, no tubes and four optional understand Nietzsche. Was acceptable, in the process, Nietzsche was transformed hem into various forms. In this paper, two Guo Mo ruo Mao Dun accept Nietzsche as Nietzsche socreated their own awards and also looked at these similarities and difference. Nietzsche Guo Mo ruo the remnants of the old feudal ideas and traditions were to break down and accept only select perspective. Nietzsche's self-discovery and individual liberty, and against the reality and accept the terms of loan 5.4 seconds, an ideal Nietzsche award was created. However Guo Mo ruo particular aspect of the acceptance of Nietzsche, whereas Nietzsche regarded as an extreme pessimist history, and his extreme caution and idealistic form of individualism was often criticized. Mao Dun the core ideas of Nietzsche 'Superman' and 'will power' noted. 5.4 All time view of life, a new morality must re-evaluate the need for a practical, based on the old tradition of Nietzsche completely against the spirit of rebellion was to have especially appreciated. But this was different Mao Dun Nietzsche and moral beliefs. What is the old morality Nietzsche corrupt, bourgeois morality and ethics, and was negative for democracy and freedom, Mao Dun dark realities facing the old Chinese feudal and traditional idea ofrevolution as a democrat were negative for. Guo Mo ruo Mao Dun optional for Nietzsche's acceptance was 5.4 times that contemporary needs can be met.

KASUMI is a 64-bit iterated block cipher with a 128-bit key size and 8 rounds Feistel structure. In this paper, we describe saturation attacks on the five round KASUMI, which requires 10 $\times$$2^{32}$ chosen plaintexts and $2^{115}$ computational complexity We also improve this attack using meet-in-the-middle technique. This attack requires 7$\times$$2^{32}$ chosen plaintexts and $2^{90}$ computational complexity. Futhermore, we attack KASUMI by controlling the value of the fixed part of the key. This attack needs 3$\times$$2^{32}$ chosen plaintexts and $2^{57}$ computational complexity.

Since the 119 fire department was legally permitted to serve in Emergency Medical Service(EMS)Operation of emergency patients in 1983, 119 EMS operation in general has made a big progress in serving the needs for emergency patients. Currently EMS operation is carried out by 119 EMS unit, private ambulance Co.,etc. But due to the public recognition and volunteers, 119 EMS operation carries the major share of the service. This observation is not surprising in that such a trends occured in Japan 20 years ago. This paper compared the 119 EMS operation conducted by the fire department in Korea with that of Japan in order to draw some inferences from the comparison. The results of the study compared to Japan were as follows: 1. Japan was higher 1.5 times in the number of EMS units per population(100,000), 1.1 times in the number of patient transports per unit. 2. Japan was higher 4.54 times in the number of the 119 EMS personnel per population(100,000), 30.6 times in that per square killometers, 30.6 times per 119 EMS unit, in per ambulance 2.48times. 3. Japan was higher 1.83 times in the number of ambulance per population(100,000), 1.26 times in that per square killo meters. 4. Japan was higher 1.7 times in the number of transport patients per population (100,000), but Korea was higher 2.68 times in the transport patients per EMS personal. 5. Compared to Japan, there was no emergency care related to ALS, for example, such as administering dugs orally and intravenously, interpreting elctrocardiograms, performing endotracheal tube or LMA insertion, using monitors and other complex equipments in Korea.
