읍치 경관이란 조선시대 관아가 있던 지방 행정 중심지 읍의 경관이다. 우리는 조선시대가 추구했던 세계관과 사회질서, 그리고 인간과 자연간의 관계가 어떠해야 한다는 것이 조선시대 읍치 경관에 명시적으로, 때로는 함축적 상징적으로 표현되어 있다고 보고 그 의미를 해독하고자 한다. 읍치의 경관과 경관 요소, 즉 입지와 주위 산과 하천의 조화, 그리고 숲을 중심으로 한 반 인공적 환경구성, 그리고 관아 건물 둥 주요 시설의 구축과 배열 및 제사 시설의 공간 분포 등은 동일한 군ㆍ현이 하나도 없을 만큼 고유하다. (중략)

The processing management forms of our country's filature factories in 1969 are summarized as follows. (1) About 80％ of total cocoon collection is made within 5 days involving peak day, and 10％ of cocoon collection is finished until 3 days before and after the peak day, (2) About 92％ of alive cocoons transported on unpaved road, and about 40％ of the cocoons purchased by all factories are loaded on trucks from common selling station which is far beyond 40km, therefore a new packing system of alive cocoons to drop the damage of cocoon qualities, should be taken. (3) 22％ of all factories in our. country have only low-temperature cocoon drying machine. Therefore the installment of hot-air cocoon drying machine is required urgently. (4) In view of cocoon qualities in our country, the grouping method of cocoon for reeling. taken by about 50％ of the factories at percent, which classify cocoons for reeling as high group (1,2,3,4 grades) and low group(5,6 grades), will have to be replaced by the method tat classify them high group (1,2 grades) middle group (3,4 grades), low group (5,6 grades). (5) The .ratio of cocoon assorting stood about 10％ in multi-ends reeling, about 15％ in automatic reeling, conclusively, the ratio of cocoon assorting for automatic reeling was higher tan that for multi-ends reeling. One person's ability for a day in cocoon assorting reaches to about 80-100kg. (6) Cocoon cooking condition requires the increase of the cooking time, the pressure and temperature used to be prolonged as much as the qualities of cocoons are material cocoon ior automatic and double cocoon machines are treated uncompletely. (7) Automatic silk reeling is being performed at 1-2$^{\circ}C$ lower in reeling water temperature and operated at about twice velocity. (8) The temperature and humidity of rereeling room stood at 25$^{\circ}C$, 67.2％ R.H and 32.3$^{\circ}C$, 51.9％ R.H of rereeling machine are showed, Average rereeling velocity is 233m/min and large reefs charged for one person are 7.5 reels and form of skein used in all factories is double skein. (9) About 73％ of water sources for filature used under-earth water. About 48％ of all filature factories in our country have not yet water purifying equipments. Installation of the equipment for these factories seems to be urgent, (10) Denier .balance, sizing reel, seriplane, are being used in most factories as self-inspection apparatus. (11) More than 90％ of the factories use the vacum tank in rereeling process and about 20％ of them use it in cocoon cooing process (12) Only 21％ of the factories use chemicals in filature process. About all them use "Seracol 100" in cocoon cooking process and "Seracol 500" in rereeling process, (13) Above survey results explain each all factories show large difference in the processing management. Therefore, it is believed that intercommunication through seminar or technical exchange will contribute to the production evaluation of cocoon in our filature industry.

1. 잠업은 식물적 동물적 가공적부문이 결합 혼합된 산업이므로 유통단계 및 유통기능이 다변족이며 타산업과 현격하게 다름. 2. 일반적 농산물의 경우도 그러하지만 잠견은 6월의 춘잠과 8월의 하추잠시기의 집중적으로 출회되므로서 상품의 수급탄력성은 거의 없고 따라서 정부의 수집조작이 요망됨 3. 잠견의 거래제도는 일정시의 특약공동판매제와 대동소이한 것으로 유통기능의 경직비를 그대로 존속하고 있음. 즉 잠견공급전량이 농협의 잠사공판매에서 공판되고 도지사가 제사공장별구견지역을 정하는 바에 따라 제사공장이 인수함. 4 유통마진은 타 상품과 같이 시장경제적거래가 성립되어 있지 않기 때문에 전혀 나타나지 않는 것 같지만 사실에 있어서는 검사제도소송심의 과정에서 상당한 마진이 존재함. 5 일시에 잠견이 공결됨으로 해서 검사제도합리화 〈기계검사〉, 건견장설치 등 사회간점자본시설 이 크게 요청됨.

The Nam-Hae Sin-sa, the South Sea shrine in Yeong-Am, Korea was a national institution for public peace and bliss, was excavated in 2000, and the shrine and the 3-way-gate were reconstructed in 2001. Hae Sin-sa, the Sea shrine is a place for religious service separated into the Nam-Hae Sin-sa, the Dong-Hae Myo, and the Seo-Hae Dan. The Dong-Hae Myo was reconstructed, but restored shrine and 3-way-gate of the Nam-Hae Sin-sa is not perfect in comparison with excavation plan in 2000, therefore new reconstruction was researched through the related literature, the analysis of historical maps and excavation results, the interview with the concerned people and the case study. This research defines the analysis of the Plan of the Nam-Hae Sin-sa Reconstruction as follows. 1. The Nam-Hae Sin-sa was the institution for religious service operated by national direct management, represents the shrine for public peace and bliss on the Mountain, the Sea, and the River. Especially the Nam-Hae Sin-sa had an important position on the pivot of international trade with China and Japan, and had a role of main shrine with another one in the Mt. Ji-ri San. 2. The name of the Sea shrine was called as Nam-Hae Sin-sa(the South Sea shrine), Dong-Hae Myo(the East Sea shrine), Seo-Hae Dan(the West Sea shrine). But the name of the South Sea shrine had changed in the early period of Chosun as Nam-Hae Sin-sa to the later Chosun as Nam-Hae Dang through the research of related literature and historical map. Such as the Seo-Hae Dan, it was constructed for the Dan, the flat raised-floor without buildings, and changed to the type of Sa-Dang with addition of buildings. 3. The historical map of Hae Sin-sa informs the types of the roof, the Mat-bae roof was used in the Dong-Hae Myo, but the Pal-jak roof was showed in the Seo-Hae Dan and the Nam-Hae Sin-sa. 4. According to the analysis of Yong-Ch'uck the unit length, Nam-Hae Sin-sa was reconstructed in the period of Koryo on large scale, but it was restored in the Chosun on middle scale. And the Unit of Yong Ch'uck was changed into Yeong-jo Ch'uck in the period of Chosun. 5. As the results, The Plan of the Nam-Hae Sin-sa Reconstruction designed the new shrine into the 3 Kan front and the 2 Kan side with 3:2 scale. An-ch'o-gong with Yong-du and Yong Mi the ornaments represents head and tail of dragon, the Un-gong and the ornament of Pa-ryun-dae-gong in the building, and the Ch'ung-ryang of the Yong-du show the image of the institution for religious service for the god of the sea who look like dragon. The inner gate building and the main entrance were designed as same plan and scale as Hyang-gyo, the Korean Traditional School and Shrine of Confucianism, on the basis of results of excavation. Raise the 3-tall gate of the main entrance with harmony of the scale and the shape, because the side of gate building has the Mat-bae roof. 6. This research shows that Plan of the Nam-Hae Sin-sa Reconstruction is composed into shrine space and reservation space from the main entrance to inner gate and shrine like Jung-ak Dan in the Mt. Gye-ryong San, and it also informs the well in the west side of Sin-sa is an important factor of the plan of shrine architecture.

The results of investigation and management analysis for the silk filatures in Korea until 1968 are evaluated as followings. (1) The average cocoon purchasing amount for a filature was found as 10,800kg and they are processed 105kg per man on the cocoon assorting process, 8,683kg per day during the drying process of which 42 percent are dried with low temperature drying system. (2) The average cocoon cooking capacity is 50 g, cocoon per minute, but the cooking capacity per man is smaller in case of larger factory. (3) The silk production capacity per month per a filature is 6,000kg and the amount gets smaller in case of larger factory. (4) The employee cost per one kg of raw silk production was found as high in smaller factory and it was found that 200~300 sets size was the optimum capacity for operation. (5) In case of multiends silk reeling machine, the employee cost for the silk reeling process acts as the most peculier factor among six different cocoon processes and it is reached to conclued to deduct the number of employees for this process in order to deduct the production cost. (6) The correlation coefficients between cost factors and total labour cost was found as 46 percent, therefore the rest (54％) will be the production cost other than labour cost.

Sajikdan(a sort of national shrine in Korea) built at the time of foundation of Joseon was entrenched into Sajik Park going through Japanese colonial era and recently the efforts to restore it is in progress. The details of change in Sajikdan in terms of diachronic analysis are as follows: Firstly, the first period refers to one prior to Japanese colonial era from the first king (also named as "Taejo" in Korean) of the Joseon Dynasty, during which it secured and strengthened the presence as a place for performing important national rites in a nation. It was built on the foot of Inwangsan Mt. at the time of the first king in Joseon Dynasty at first, was destroyed fully by fire during a Japanese Invasion period to Korea(1592-98) and afterward its ancestral ritual facilities were completed under the regime of Youngjo. However, as Japanese intervention coming to the fore, its place was destroyed and then ancestral rites were also abolished in 1908. Secondly, next period falls on 1910 to 1944 when it was transformed and entrenched into a park by the Japanese Empire. While facilities related to a park and an heterogeneous building around the part of boundary were set up, the area of altar, a ritual house and d door of Sajikdan were also designated as historical remains and treasures. Thirdly, this period refers to one from Korea's liberation year from Japanese colony(1945) to the year of 1984 when it had a mixed placeness with the statues, monuments and buildings with heterogeneous nature built. Furthermore, a door of Sajikdan was removed and reconstructed over twice due to opening of Sajik Tunnel. Fourthly, a final period falls on 1985 to the present when efforts are in progress to restore the historicity and symbolism of Sajikdan. A plan for restoration is promoted but now is a difficult time suffering from troubles caused by residents' resistance. Scrutinized historical researches through excavation investigation and residents' understanding are required altogether for restoration of Sajikdan.

Since future maintenance cost estimation of infrastructure involves uncertainty, it is important to make use of a failure prediction model. However, it is difficult for local governments to develop accurate failure prediction models applicable to infrastructure due to a lack of budget and expertise. Therefore, this study estimated the life expectancy of asphalt road pavement of national highways using the Bayesian Markov Mixture Hazard model. In addition, in order to accurately estimate life expectancy, environmental variables such as traffic volume, ESAL (Equivalent Single Axle Loads), SNP (Structural Number of Pavement), meteorological conditions, and de-icing material usage were applied to retain reliability of the estimation results. As a result, life expectancy was estimated from at least 13.09 to 19.61 years by region. By using this approach, it is expected that it will be possible to estimate future maintenance cost considering local failure characteristics.
