Summary. With the advent of the internet and the concept of social network service, people of present days are flooded daily with new varieties of the communication channel. One of the most affected group of people may be singing artists. This over-growing number of communication channels pushes singers to put just as many efforts to establish and groom his or her unique identity as an artist. In old 'pre-internet' days, any singing artist's superficial features, like the tone of voice or stage presentation, were the only transcriptive criteria upon which the artist was adjudicated. New developments in technology, however, have set a new paradigm for singing artists of the present day. Respective criteria of today extend beyond the realm of music and comprise musicianship, requiring much scrupulous attention on the various area to propagate and protect one's unique identity as an artist. In light of this phenomenon, this study looks into Mr. Lee, Seung Hwan whom may undoubtedly be one of the most representative ballad singers of 90's. We can probably see his music in 5 features such as Rock Sound based on using various instruments, World Music Sound, Massive Choir, Challenge for the New Style, Lyrics of Life. As a singer-songwriter, he colored numerous albums and influenced the era, unlike many others. He still works vigorously, worthy of his epithet, a 'present-progressive' artist. The object of this study is how Mr. Lee has been proactively dealing with the phenomenon above.

In this paper, we propose thermal resistance compact model of FinFET structure that has hexagon shaped source/drain. The heating effect and thermal properties were increased by reduced size of the device, and thermal resistance is an important factor to analyze the effect and the properties. The heat source and each contact that is moved heat out were set up in transistor, and domain is divided by the heat source and the four parts of contacts : source, drain, gate, substrate. Each contact thermal resistance model is subdivided as a easily interpretable structure by analyzing the temperature and heat flow of the TCAD simulation results. The domains are modeled based on an integration or conformal mapping method through the structure parameters according to its structure. First modeled by analyzing the thermal resistance to a single fin, and applying the change in the parameter of the channel increases to improve the accuracy of the thermal resistance model of the multi-fin/ finger. The proposed thermal resistance model was compared to the thermal resistance by analyzing results of the 3D Technology CAD simulations, and the proposed total thermal resistance model has an error of 3 % less in single and multi-finl. The proposed thermal resistance model can predict the thermal resistance due to the increase of the fin / finger, and the circuit characteristics can be improved by calculating the self-heating effect and thermal characterization.
Present study analyzes the rooftop gardening status, floristic composition and cost and return of the rooftop garden in Sylhet City Corporation of northeastern Bangladesh. Data was collected from 450 rooftop gardeners randomly during July-September 2010. Study reveal that rooftop gardening is generally for mental satisfaction (95.3%) followed by leisure time activity (87.8%) in the study area and almost all the family members of gardeners' were involved; while collection of planting materials, sites preparation and marketing of products were reported to be carried out by males only (male 71.33%). Middle income classes were most interested in rooftop gardening (43.78%). The survey recorded 53 plant species (35 families) of which Cucurbitaceae family represented highest eight species. Shrubs (28%) were highest followed by herbs (26%) among agri-crops (36%) and flower species (30%). About 89% of the rooftop gardeners procured planting materials from nursery, market, fair, neighbor, relative and friends and they mostly prefer to use seedlings (48%) for roof gardening followed by direct seed sowing (21%). Gardeners sell products sporadically in different local markets, directly or through intermediaries, with no uniform pricing for system. Rooftop gardening improves the food security and meet nutritional deficiency to the gardeners. Survey revealed that generally very few people consider rooftop gardening commercially to get profit and from the cost-return analysis this gardening system can be economically viable if proper and scientifically managed. The study conclude that active government and NGOs could play vital role to increasing this activities by providing training and motivate people with technical aspects of rooftop gardening.
The seasonal distribution of Maurolicus muelleri eggs and larvae were determined using samples collected from the Korea Strait and the southern part of the East Sea in May and November, 1992, August, 1993, and January, 1994. The eggs were most abundant in summer and the larvae in spring, while, their abundance was low in winter. The eggs were mainly found from in all season around sea of the front area of latitude $35{\sim}36^{\circ}N$ and the West Channel of the Korea Strait found the middle or bottom water lower than $15^{\circ}C$. The seasonal distribution of the eggs in the western Korea Strait varied according to the structure of the bottom cold water of the Korea Strait. The M. muelleri larvae in different stage were most abundant in the front area of latitude $35{\sim}36^{\circ}N$. The spawning and hatching area of the M. muelleri was considered to be the front area located in the shelf break, and some eggs can be transported into the Korea Strait by westward cold bottom current in summer. The Korea Strait would be the southern margin of the distribution of Maurolicus muelleri eggs and larvae of the East Sea.
Purpose - In this research, the expectation level of service of Incheon International Airport was investigated. Service expectation level is critical to the customers' satisfaction and should be managed. Regarding the expectation level of service, the concepts have been defined and introduced by some researchers including Zeithaml, Berry, and Parasuraman (1993). However, due to the difficulties of measuring the level, researches on the expectation level of service have been limited. The main reason of difficulties of measuring the effects is that desired service, adequate service, perceived service, predicted service which are the conceptual components of the expectation level of service are psychologically described concepts and thus are hard to set up standards and to measure numerically. All that one can discern is that desired service level is higher than adequate service level or perceived service level is lower than predicted service level under the certain conditions, etc. Research design, data, and methodology - In this research, the level of service and factors affecting the level are investigated using the case of an Airport. The main idea of research is to investigate whether a supposed factor that is alleged to affect the expected service level is working empirically. The supposed factor is service provider's promise to provide certain level of service to customers. Results - The research results can be summarized as follow. First, service provider's promise, in this case the Airport's Service Quality Award by Airports Council International which can be regarded as objective promise to provide the certain level of service to customers is turned out to be influential to factors affecting expectation level of service. Second, service provider's promise affects to move the customers' expectation level of service upward especially the service of delivering the necessary information to customers in the airport correctly and swiftly. Conclusions - The implications of the research results are, first, customers' expectation level of service in influenced by service provider's promise, second, airport's service award increases the level of customers' service level and as a result for the airport to meet the customers' expectation level of service more efforts should be made.
The purpose of this experiment intend to evaluate the quality of the image based on the orbit and basal ganglia with high radiosensitivity for the noise, SNR and dose using the five kinds patient fixing pad in brain phantom MDCT(BrillianceTM CT 64 slice, PHILIPS, Netherward). The noise had a higher values in AP than those of others, but the SNR was lower in AP than those of others. The SNR was higher in UP than those of RP, PP, SP and AP. The UP, RP and PP were no statistically significant(p>0.05), whereas it was significant difference between UP, RP, PP and SP, AP(p<0.05). This is causes of the noise difference is generated due to the differences in the radiation absorption dose in accordance with each the component of the absorbed dose level of the detector according to the reference line and each of SOML when the radiation exposured. The CTDIvol(mGy) and DLP of orbit and basal ganglia were 56.95, 911.50, respectively. There is no difference between both mean dose. In conclusion, it is possible to distinguish among a kind of 5 patient fixing pad by using brain phantom MDCT. Overall, patient fixing pad of UP, RP and PP based on a brain phantom MDCT can provide useful information.
Introduction: In this study, we compared sleep structure, EEG characteristic of pediatric obstructive sleep apnea (OSA) and normal controls which were matched in sex and age. Methods: Fifteen children (male:female=4:11) who complained snoring and were suspected to have sleep apnea and their age and sex matched normal controls (male:female=5:10) have been done nocturnal polysomnography (NPSG). Sleep parameters, sleep apnea variables and relative spectral components of EEG from NPSG have been compared between both groups. Results: Pediatric OSA group were distinguished from normal controls in terms of apnea index, respiratory disturbance index and nadir of oxyhemoglobulin desaturation. Pediatric OSA group showed increased percent of sleep stage 1, decreased rapid eye movement sleep percent and increased delta power in O1 EEG channel. However other sleep parameters and spectral powers were not different between two groups. Conclusion: In pediatric OSA group, sleep structure parameter disruption may be not prominent as the previous studies for adult OSA group because of including mild OSA data in diagnostic criteria. In addition, EEG changes might not be distinct due to low arousal index compared to adult OSA patients. We can observe general characteristics and particularity of pediatric OSA through this study.

The purpose of this study is to provide some basic data for the direction of nursing education and practice to prevent nursing malpractice as investgating perception of the nurse on the nursing malpractice and its case. Data were collected from 450 nurse working in four general hospitals which were located in Chonbuk province from November 9 to 21, 1998 through questionnare. The structured instruments developed by the reseacher were used for collecting data. The Results were as follows: 1) As for the cognition of the nursing malpractice case, the transfusion accident was 37.3%, the side-effects of KCL injection(19.3%), hymen rupture by uterus cancer test, the side-effects of aminophyllin injections on dyspnea patient and the others were 10% below. 2) With regard to the channel of the perception of the nursing malpractice case, mass-communication was taken first and followed through by neighbors, In-service education, school education, continuing education 3) As for the direct${\cdot}$indirect experience of the nursing malpractice case, transfusion accident was 51.3%, the fall of NPO patient after an operation 40.1%, the side-effect of KCL injection 32.5%, suicide of the psychiatric patient 32.5%, and the others were 30% below. 4) The possibility of nursing malpractice case was an average 2.57(${\pm}$0.91) and the highest was the fall of the NPO patient after an operation. 5) The perception on the responsibility of the nursing malpractice in its case was indicated as a joint-fault in ten nursing malpractice instances. As compared to the real decision, nurse's perception of the responsibility in the fall of the NPO patient after an operation, the side-effect of KCL injection, the tracheal edema of the patient who had a thyroid operation, the suicide of psychiatric patient, the hymen rupture by uterus cancer test accorded real decisions. But the other cases were different from the real decisions. These cases were perceived as ones of joint fault even in cases determined as Dr's single fault cases or those in which both doctor and nurse were declared free of fault. 6) Knowledge levels of the nursing malpractice, school education and In-service education were perceived as low but anxiety levels of the malpractice were high. 7) With regard to the countmeasure of the hospital after nursing malpractice, the rate answered as "the practice settled the accident temporarily and forced the person in charge to be punished" was highest. In conclusion, the level of the cognition of the clinical nurse on nursing malpractice cases was low. As nurses' perception on the responsibility of the nursing malpractice case was compared to the real decision, there was a difference in five cases out of the ten cases.

When an RFID reader attempts to read tags, interference might occur if the neighboring readers also attempt to communicate with the same tag at the same time or the neighboring readers use the same frequency at the same time. These interferences cause the RFID reader collision. When the RFID reader collision occirs, either the command from the reader can not be transmitted to the tags or the response from the tags can not be received by the reader correctly. RFID reader anti-collision algorithms have been developed to reduce it. One of the best blown reader anti-collision algorithms is the Colorwave algorithm proposed by MIT. The Colorwave algorithm reduces the reader collisions by having the readers operate at different times. In Colorwave the time is divided into frames and a frame is divided into a number of slots. Each reader can access the tags using the slot time assigned to it. Depending on the probability of the interference, the colorwave adjusts the frame size to improve the efficiency. In this paper, we analyze the operations and the performance of the Colorwave algorithm and identify the problems of the algorithm. We also show that by adding some modifications to the algorithm the performance can be improved significantly.
