일반적으로 영상내의 중요한 정보는 객체 영역에 많이 포함되어 있다. 객체 영역 우선 전송 방법은 영상의 전 영역에 대해 동일한 중요도로 전송하는 일반적인 점진적 부호화 방법과는 달리 객체 영역만을 우선적으로 부호화 하여 전송하기 때문에 짧은 시간 내에 원 영상을 보다 빨리 파악할 수 있다. 따라서 본 논문에서는 양방향 반올림 필터를 이용한 MRWD기반 객체 영역 우선 전송 기법을 제안한다. 제안한 방법은 양방향 반올림 필터에 의해 객체 영역을 추출한 후, MRWD를 이용하여 부호화를 수행하므로, 객체 영역의 웨이브릿 계수들을 우선 전송함으로써 매우 낮은 비트율에서 영상내의 중요 정보를 파악할 수 있다. 따라서, 인터넷상에서 사용자가 영상을 검색할 경우 보다 빨리 원하는 정보를 파악할 수 있어 검색 시간과 검색 효율을 개선시킬 수 있다.

Objectives: In narcoleptic patients diagnosed with ICSD (international classification of sleep disorders, 1990) criteria, nocturnal polysomnography, and MSLT (multiple sleep latency test), we tried to find characteristic features of quantitative electroencephalography (QEEG) in a wakeful state. Methods: We compared eight drug-free narcoleptic patients with sex- and age-matched normal controls, using computerized electroencephalographic mapping technique and spectral analysis. Absolute power, relative power, interhemispheric asymmetry, interhemispheric and intrahemispheric coherence, and mean frequency in each frequency band (delta, theta, alpha and beta) were measured and analyzed. Results: Compared with normal controls, narcoleptic patients showed decrease in monopolar interhemispheric coherence of alpha frequency bands in occipital ($O_1/O_2$), parietal ($P_3/P_4$), and temporal ($T_5/T_6$) areas and beta frequency band in the occipital ($O_1/O_2$) area. Monopolar intrahemispheric coherences of alpha frequency bands in left hemispheric areas ($T_3/T_5$, $C_3/P_3$ & $F_3/O_1$) decreased. Decrease of monopolar interhemispheric asymmetry of delta frequency band in the occipital ($O_1/O_2$) area was also noted. The monopolar absolute powers of beta frequency bands decreased in occipital ($O_2,\;O_z$) areas. Conclusion: Decreases in coherences of narcoleptic patients compared with normal controls may indicate fewer posterior neocortical interhemispheric neuronal connections, and fewer left intrahemispheric neuronal connections than normal controls in a wakeful state. Therefore, we suggest that abnormal neurophysiological sites of narcolepsy may involve complex areas such as neocortex and subcortex as well as the brainstem.

The objective of this research is to reconstruct an aristocratic officer's travels by analysing Yu, hee-chun's diary, Miamilgi. Yu had kept his diary for eighty three months, from October 1567 to May 1577, and there were twenty six times of travel logs which are analysed in this research. As a result of the analysis, his travels can be divided into official travels and private travels. Sixteen times of official travels were comprised of inspection tours for parishes as a superintendent of Jeonra province, trips to supervise maintenance works of royal tombs and to worship the tombs, to carry out the sanjae (rituals in the mountains) as a second minister of the ministry of rites. It was difficult for him to have private travels as he continually served as a royal officer. He had got only 10 times of private travels during the eighty three months for maintaining the ancestor's tomb and worshiping the ancestors, for recuperating himself and his wife, and for constructing his new house. All of these travels were long-distance ones. In terms of his travel routes, he frequently used royal main trunks, e.g. 'Haenamro' (from Seoul to Damyang), which were maintained by the royal government. The main reason of his frequent using of trunk lines was that convenience facilities such as the royal post stations (Yeok) and royal inns (Won) were equipped well in these roads so it was easy to get horse change services and lodging and boarding. The fact that main trunks were chiefly straight lines and the shortest way was rather secondary reason. On the other hand, when he was a superintendent of Junra province, he had four times of round inspection on all parishes of Junra province, following the tour routs covering all over the province. As he was incumbent royal officer, he started his travel by getting a permission from the king. Simultaneously, he made ready some travel items. Among the items, horse was most important one for the journey. After finishing all the preparing processes before the departure, he had special farewell ceremony for the King, Sookbae, and had a small party with his friends called Jeonbeul. Main transportation means for his travel was horse, and many kinds of horses such as royal government's horse, Yeokma, local government's horse, Swema, as well as his private one were used. Additionally, he used a palanquin while he was doing inspection trip as a superintendent of Junra province. Yu was incumbent officer so he mostly lodged in local government guest houses. If he could not find out any local guest house, he was lodged in royal inn, and in his relatives houses or irregularly in buddhist temples. Most meals were supplied by local royal governments. The activities in his journeys were varied on his travel objectives. In his private journey, it was the main activities that maintaining ancestor's tombs and having a memorial service. During the trip, he visited his relatives. His official trips, on the other hand, had a regularity. Main activities were dealing with public works, and visiting Hyanggyo (country public school). However in the midway, he visited his relatives and had a journey to scenic places.

This research argues that Pansori had patrons in its development. Patrons are commonly discussed aspect of history of any art form. Pansori is no exception. While Pansori originally began as the art of the common people, Yangban class became the primary audience. This paper examines the role of royal family of Choson dynasty in development of Pansori. Heungseon Daewongun (흥선대원군) in particular was a Pansori aficionado. The record around Daewongun's involvement to Pansori proves that heavy monetary investment was made. He hosted Pansori competitions and sponsored creation of Pansori tradition, Boseong Sori (보성소리) and Gangsanje (강산제). Also the aspect of Pansori patronage lies not just in Yangban class, but also in Jung'in class, which is roughly analoguous to European bourgeois in that they were not of Yangban class, but had gained monetary status, and had aesthetics of both Yangban and commoner class. I argue that Heungseon Daewongun's ties to the Jung'in class is reflected in his actions towards Pansori artists. The traditions he had sponsored have important characteristics, including sophisticated lyrics heavily utilizing Classical Chinese poetry, highly artistic musical composition, and conservative Confucian ethics. Those characteristics indicate that the Pansori traditions sponsored by the royal patrons have changed to cater to their artistic taste and philosophy. This paper conducts a textual comparative analysis between Gangsanje Pansori Jeokbyeokga (강산제 판소리 적벽가), Dongpyeonje's Pansori Jeokbyeokga (동편제 판소리 적벽가), and Seopyeonje Pansori Jeokbyeokga, who share the same plot yet offers a stark differences in tone, philosophy, and sense of humor. Daewongun was a primary sponsor of Pansori, which proves that Yangban class and the royal family have played important role as patrons of Pansori.

The quantitative EEGs of obsessive-compulsive disorder patients were analyzed using spectral analysis and compared to age and sex-matched controls. The subjects were 19 patients(men=15, women=4) suffering from obsessive-compulsive disorder(DSM-III-R). Absolute power, relative power and interhemispheric asymmetry of EEG were used to compare obsessive-compulsive disorder patients with controls. In order to fit the EEG data to a normal distribution, a log transformation of power values of every bandwidth in each deviation was calculated prior statistical analysis. The Wilcoxon rank test was performed to compare obsessive-compulsive group to the control group. In obsessive-compulsive disorder, abnormalities of quantitative EEGs are prominent in fronto-central. These results ore compatible with other brain imaging studies of obsessive-compulsive disorder and suggested that fronto-central area plays an important role in the pathophysiology of obsessive-compulsive disorder.

We investigated the effect of modified atmosphere packaging (MAP) on the removal of astringency and overall quality of astringent persimmons (Diospyros kaki T. cv. Miryangbansi). Persimmons were packaged in 0.08, 0.10, or 0.12 mm low-density polyethylene film and then stored at $0^{\circ}C$ for up to 100 days. Concentrations of $O_2$ and $CO_2$ in the packaging maintained lower and higher as the film thickness increased Weight loss was strongly retarded by all three MAP films. Soluble tannin content decreased as the film thickness increased. The astringency of persimmons disappeared after 60-70 days in 0.12 mm film, after 80 days in 0.10 mm film, but did not disappear after 100 days in 0.08 mm film Loss of flesh firmness and decline in external appearance were slower in persimmons in 0.08 and 0.10 mm films than in those in 0.12 mm film. Our results show that 0.10 mm LDPE films can be effective for maintaining the quality and removal of the astringency of astringent persimmons.

This paper uses the diary entitled Kieo, which was kept by Ryu Hyeong-eop for 38 years, to analyze the active space of small-scale Yangban landlords. Ryu lived during the period spanning from the end of the Taehan Empire through the colonial era. The researcher classified the contents of Kieo into different sections which were divided according to different stages of the writer's life, his objectives, destinations, and periods, and based on the writer's life-cycle, strived to recreate his spatial activities. As a result, researcher was able to ascertain that Ryu's spatial activities gradually increased, and that his active space also continuously expanded. Ryu's active space during his youth was narrow and centered around certain specific places. However, this active space gradually increased as time went by. It was during the middle stages of his life that the volume of his spatial activities was the heaviest. In addition, the objectives of his outings also became more diversified over time. This change was originated in the larger changes in his roles within the family and community, as well as by the changes in the periodic situation. Moreover, the regional sphere of Ryu's outings, including his day and over nights trips, allowed the researcher to form a better understanding of the daily living area of the Yangban.
