This study aims to examine the early use of Da-bo tap and their transformation by analyzing the various meanings of the term pagoda in Chinese translations, the Sanskrit version of the Lotus Sutra, as well as Dabotap in the Mogao Caves of Dunhuang. In addition, we aim to highlight changes in Dabotap usage, which started out as residential spaces, but transformed into burial spaces over time. The details can be summarized as follows. First, early Buddhist monuments were usually either pagodas serving as burial places for the dead or shrines that were not. A Dabotap is a type of pagoda enshrining the body of Prabhutaratna, and was initially used as a residential space, rather than a burial place for the dead. Second, the terms stupa and caitya are clearly distinguished from each other in the Sanskrit scriptures, and stupa is also further classified into dhatu, sarisa, and atmabhava based on the object being enshrined. In Gyeon-bo-tab-pum, the preconditions for caitya to transform into stupa is presented by explaining that worshipping the space enshrining the body of Prabhutaratna is worthy of the same status as the space enshrining sarira. Third, the Mogao Caves of Dunhuang had been depicted from the Western Wei of the Northern Dynasties until the time of the Yuan Dynasty. It was used as a residential space until the early Sui Dynasty, but was used as both residence and burial places until the Tang Dynasty when pagodas were first being constructed with wheel or circles forms on top, which then gradually changed into stupa (grave towers).

In Korea, burial is the most common method of disposing animal carcasses culled due to brucellosis infection. However, burial has many disadvantages such as shortage of appropriate burial sites, possibile pollution of ground water supply, and negative view of the public. In this study, we have reviewed 3 legal methods for disposing bovine carcasses, which are burial, incineration, and rendering. We also described the overall process, advantages and disadvantages, and required costs for each method. About 75% of bovine brucellosis outbreak farms had less than 3 reactors, and in our study, rendering required the least amount of cost for farms with a small number of reactors (1-3 heads). Our findings suggest that the use of rendering should be encouraged for farms with bovine brucellosis and other methods considered only if rendering is inappropriate.

본 연구는 물리탐사방법 중 GPR을 이용한 고고학에서의 활용 가능성을 제시하기 위한 것이다. 따라서 탐사의 결과를 보고 고고학자들이 직접 발굴에 응용하여 발굴로 검증된 예만을 제시하였다. 탐사지역으로는 강원도 원주시 부론면 법천리 고분군, 경상남도 고성군 송학동 1호분, 그리고 일본의 사가현에 위치한 요시노가리 옹관유적이다. GPR 탐사의 time slice 분석법을 유구의 평면적인 분포양상을 파악하는데 이용하였다. 이 탐사법으로 각 유적지에서 이상반응(Anomaly)을 찾을 수 있었으며 지하의 각 깊이별 문화유적 분포양상의 변화를 살펴볼 수 있었다. 원주 법천리 유적에서는 석실 및 기타 석재 유구들이 GPR에 대하여 강한 반사신호를 나타내어 백제시대 유구의 분포상황을 확인할 수 있었다. 또한 고성 송학동 1호분은 그동안 고고학계에 논란이 되어왔던 전방후원분의 진위여부에 대하여 탐사 및 발굴을 통하여 3개의 분묘가 합쳐진 것으로 들어났다. 특히 일본의 요시노가리 유적의 2열 옹관 매장지는 발굴을 GPR탐사로 대신한 좋은 예이다. 이상의 조사에서 GPR탐사를 이용하여 유구의 분포범위 및 양상을 발굴 전에 미리 확인할 수 있었다.

If a spoiler was attached to the pipeline investigated in a previous study, a strong flow and vortex at the lower part caused scouring and thus an asymmetric pressure distribution, which assisted in the analysis of the self-burial structure where a down force was applied to the pipe. However, only the fluid-pipe interaction was considered, excluding the medium (seabed), when practically burying the pipeline. Thus, this study applied a numerical model (LES-WASS-2D) to directly analyze the non-linear interactions among the fluid, pipe, and seabed in order to perform numerical simulations of a pipeline with a spoiler installed on the seabed. This allowed the self-burial mechanism of a pipeline with a spoiler to be analyzed in the same context as the previous study that considered only the fluid-pipe interaction. However, when a pipeline was installed on the seabed, a strong flow and vortex were found at the front of the bottom, and a spoiler accelerated the fluid resistances. This hydraulic phenomenon will reinforce the scouring and down force on the pipeline. In the general consideration of the numerical analysis results by the specifications and arrangements of the spoiler, a pipeline with a spoiler was found to be the most effective for the self-burial function.

It is very important to treat infected livestock carcasses safely and quickly. In this study, the degradation characteristics and odor generation characteristics of carcasses were investigated during the treatment of swine carcasses using the anaerobic burial composting method. While the carcasses were decomposed, the temperature remained high, at $40{\sim}55^{\circ}C$ on average, and most of the carcasses were decomposed rapidly. The major odor-contributing substances in the buried composting method are sulfuric odor substances such as $H_2S$, $CH_3SH$, dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), and the odor contribution of these substances is 93~99%. Among them, $CH_3SH$, which accounts for about 56~89% of odor contribution, was the most representative indicator substance. Despite the anaerobic digestion process, the methane concentration in the digestion process was as low as 0.5~0.8% at the burial point of the carcass. The odor and methane produced during the decomposition of the carcasses decreased considerably during the discharge to the surface layer through the buried layer consisting of compost. These results suggest that anaerobic high temperature burial composting is one of the most useful methods to treat carcasses of infected livestock.

The interaction of ground ice features with underlying seabed is one of the major considerations in the design of Arctic pipeline systems. Regarding the development of offshore gas field near Sakhalin Island, which is an ice-infested area, in this paper an ice scour model to determine the burial depth of Arctic offshore pipeline is studied. Using a simplified ice-seabed interaction process, ice scour depth is easily estimated. This nonlinear numerical model can simulate the scouring process for various enviromental parameters such as ice mass, incoming velocity, soil strength. This study also deals with interaction forces during the scouring process in sloping seabed conditions and discusses the ice loads that are transmitted through the seabed soil.

Subsea pipelines are designed to transport mixtures of oil, gas, and their associated impurities from the wellhead that can have temperatures as high as $100^{\circ}C$, while the external temperature can be as low as $5^{\circ}C$. Heat can be lost from the subsea pipeline containing high-temperature fluid to the surrounding environment. It is important that the pipeline is designed to ensure that the heat loss is small enough to maintain flow and avoid the unwanted deposition of hydrate and wax, which occurs at a critical temperature of approximately $40^{\circ}C$. Therefore, it is essential to know the heat loss of subsea pipelines under various circumstances. This paper presents a comparison between numerical analyses and existing theoretical formulas for different backfills and burial depth.

Grounding electrodes with higher burial depths are evaluated to have better performance, due to the domestic practice that puts the grounding resistance as the standard of performance evaluation, while grounding resistance decreases as the burial depth increases. However, The dangerous voltage is necessary for the analysis. Because the performance evaluation of grounding electrodes should include not only grounding resistance but also the dangerous voltage(mesh voltage and step voltage). So in this paper, The dangerous voltages of mesh grounding and rod grounding were analyzed for using computer simulation and miniature grounding model.

This study investgates the significance of Chosun burial clothing in 15th to 17th Centuries by examing the costumes recorded in the ryesu (ritual books). Referring to description of the mouring-rit-ual in the the Kujoohryei(국조오례의), the sangryebiyo(상례비요), they exhibit little differ-ence in the ceremonial procedure, this implies that the the Jujagarye, the oldiest Chinese Ryesu, had influence on the manner of Chosun. The Kujoohryei(국조오례의) written-in 15th Century played a paramount role in domesti-cation of burial costume(염습의) which had been performed by the Jujagarye(주자가례), and the sangryebiyo(상례비요) etc written between 16th and 17th Centries promoted to genealize the mouring-ritual to the ordinery people. In the period, ryemsupui(염습의, clothing for the dead) is costumes for 'sup(습)', sofyum(소렴), and 'daeryum(대렴)' in the mourning ceremorial procedure, and for postliminal rites in the rites of passage. The reason of using clothing which they put on the dead's own daily clothing stands for eagerness for lasting life not only in this world but also in the other world.

본고에서는 경주 월성북고분군에서 조영된 적석목곽분의 존재 양태의 두 측면, 즉 묘형과 집단복합묘군에 대해 고찰하였다. 적석 목곽분은 호석으로 한정된 봉분 안에 단위묘곽이 설치된 원형의 단위고분이 기본형으로, 그 묘형은 단일원분, 연접분, 다곽분으로 구분된다. 단일원분은 피장자 1인의 단장분이고, 연접분은 일반적으로 부부나 혈연관계인 가족의 합장분이다. 다곽분도 대개 최하위 랭크의 묘곽들로 구성된 합장분으로, 월성북고분군의 왕릉구역에만 존재했던 것으로 보인다. 한편 현재 조사가 진행 중인 경주 월성북고분군의 쪽샘지구에서는 미고지를 따라 고분들의 소구역 군집현상이 보인다. 이는 당시 사람들이 친연관계에 따라 소집단별로 미고지를 점유하여 그 축선 방향으로 중형급 단일원분이나 연접분을 조영하고 그 주변으로 다수의 소형분들을 위성처럼 배치하여 집단복합묘군을 형성해 나갔기 때문이다. 대릉원지구를 비롯한 경주 월성북고분군의 왕릉구역에서도 고분들은 집단복합묘군을 형성하였다. 왕릉구역의 집단복합묘군은 마립간 왕릉인 초대형 단일원분이나 왕과 왕비의 합장릉인 초대형 표형분을 주분(主墳)으로 그 주변에 대소형 고분들을 배치하여 형성되었다. 집단복합묘군의 피장자 중에는 신분이나 사회적 인격이 대등한 부부나 혈연관계의 가족이 포함되었겠지만, 고분들 사이의 랭크 차이가 현저하여 피장자 모두가 혈연관계였다고 볼 수는 없다. 집단복합묘군에 포함된 하위 랭크 고분의 피장자들은 주분 피장자 및 그 가족과 주종관계의 '소속인'들이었다고 판단된다. 경주 월성북고분군의 적석목곽분에서 보이는 이와 같은 묘형과 집단복합묘군은 신라 마립간시기 중앙의 사회집단과 그 성격을 말해준다. 앞으로 이에 대한 좀 더 정밀한 분석은 당시 신라사회의 여러 측면을 밝히는 데 많은 기여를 할 수 있을 것으로 기대된다.
