The microstructure, mechanical properties and residual stress of flux-cored arc welded ASTM A516-70N carbon steel using a Mn-based low-temperature transformation (LTT) welding consumable were investigated. Microstructural analysis with X-ray diffraction, an electron backscattered diffractometer and a field-emission scanning electron microscope showed that the LTT weld metal was made up of ferrite, austenite, martensite, and bainite with phase fractions 50.5%, 0.2%, 40.2% and 9.1%, respectively. The increase in hardness and the decrease in absorbed impact energy of the LTT weld metal compared with conventional consumable welds were confirmed to be due to the relatively high fraction of martensite phase in the weld metal. The welding residual stress distributions in three coupons (LTT, conventional and postweld heat-treated conventional weld) were compared by the results using instrumented indentation testing. The LTT weld coupon showed compressive residual stress distributed in the weld metal and heat-affected zone (HAZ), confirming previous studies in which this residual stress was attributed to a martensitic phase transformation at relatively low temperature. PWHT in the conventionally welded coupon considerably reduced the tensile residual stress distributed in the weld metal and HAZ. The LTT consumable, however, showed a significant advantage in welding residual stress, even compared with the heat-treated conventional consumable.

In order to survey the traditional salt production at the eastern coast, Young-Hae, in Yi-dynasty, data of salt production were collected through interviewing with whom has received the skill from ancestors and analyzed the data. The results obtained were as follows. Salt-producer take the salt water containing much salt and then he transported the salt-water by having water buckets an back in with using the water-toting device (Mul ji ge). Finally he carried out the irrigation (Mul dae gi) to a ditch (Dorang). It is noteworthy that the East-sea salt production method was not selecting a method of salt-pond style with a bank for salt production but using the salt water transportation fashion without a bank for that. Judging from these facts, we could conclud that traditional salt production method was handed down into the Yi-dynasty from ancient times.

葬儀禮와 古典文學에 나타난 죽음觀考究 - 祭亡妹歌 와 바리공주 를 중심으로 -

Man must experience death at some point in his or her life. They are born, get old, get sick, and die. This is called a human lifetime. People believe that there is a world after death, in other words, they go to an afterlife when they die. This is because the answer to the question, “What is death?” is the shortcut that opens another life. What follows is a consciousness that treats death as a problem after death, the ultimate concern of man. All concerns for disease and death are just different expressions of concerns for life. Literature constantly defies death. This study would examine the thoughts of death appearing in Korea’s classical literature to find what our foregoers’ view of the other world was like. Of the Shilla Hyang-ga, Master Wolmyeong’s Jemangmaega and the epic shaman song, Princess Bari, were selected as subjects of the analysis. Both have death as a subject, and the former is poetic literature while the latter is prose literature, a work that implies the phases of the times on death. Jemangmaega is a poem of prayer that demonstrates that all worldly things (Jehaengmusang- Sabbe sankhara anicca) are impermanent and turns the Buddhist view of death and life to transcend this ultimately to Amitabha Buddha (Muryangsu). In other words, a spirit of convergence that the world of the living and the world of the dead overlap in Buddhism is sung at the funerals. The epic shaman song Princess Bari is a heroic tale in which the heroine Princess Bari overcomes hardships and becomes a god, which is literature with sanctity and magical nature sung in rituals. Koreans’ view of life and death or what forms the basis of the mythical view of the universe is shamanism as a faith of the people. This view of life and death has the idea of paying off each other’s grudges (Haewon) to hold a Salpuri ritual with a Jinogi-gut ritual. It was found through the funeral rites. that, just like death belongs to the living, the rite of death also belongs to the living.

19세기초 경북북부의 인구감소와 조세 : 安東과 尙州를 중심으로

본 논문은 1759년과 1831년의 안동·상주의 인구증감, 생산능력, 식량소비량의 추계를 통하여 인구와 조세 그리고 경제발전과의 관계를 비교하여 살펴보았다. 안동과 상주는 1759년에 비하여 세도정치기인 1831년에 인구가 감소하였다. 안동은 1/3이상의 인구감소를 보였는데 이를 생산능력과 소비량의 관계를 통하여 인구압력이 너무 강하여 조세부담과는 관계없이 잉여생산물을 통한 경제발전은 어려운 상황에 놓여 있었다. 반면 상주는 잉여생산물이 발생할 수 있는 한계점에 놓여 있었다. 따라서 조세수준에 의하여 경제가 발전할 수 있는 가능성이 나타나고 있다. 실제 조선정부의 조세정책에 의해 법정조세율은 10%내외를 기록하였으나, 문헌에서는 실제보다 축소되었음에도 불구하고, 비공식적 조세인 환곡, 신역, 잡세 등의 부담이 법정조세율을 상회하고 있었다. 그 결과 실질조세율은 상주의 확대재생산의 길을 막아 버리는 결과를 가져왔다. 결국 19세기이후 세도정치가 들어선 이후 수탈의 강화로 인구와 경제발전이 저해됨으로써 개항이라는 외부충격을 흡수할 수 있는 능력을 상실하게 만들었다.

The goal of this paper is classified as follows; Firstly, this paper is to examine "traditional broiled-salt production process", namely the East - sea salt manufacture circumstances in Yi-dynasty Age. Secondly, it is a group of working study which makes clear effect it on Yi-dynasty's social and economy. Thirdly, it is studying to find out "traditional broiled-salt production method" which is no leave no trace behind and any record in our handicraft history. Generally speaking, salt is necessary to our life together with food and shelter from old days to the present time and finally it can be usable to data understanding how salt was produced and sold in the East sea which has unfavorably geographical conditions. Our manual labor history is deeply related to the modernization. Especially, the East-sea broiled salt production in Yi-dynasty has something to do with the fishing industry mutually and also is strongly contributed to the progress of commercial business. As a result of examining the on-the spot survey, analyzing the data and arranging those facts, now, I concluded that the salt production method of the whole East sea district and Young-Hea area is as follows ; First, salt-producer chose the salt water containg much salt and then he transported the salt-water by having water buckets an back with using the water- toting device (Mul ji ge). Finally he carried out the irrigation(Mul dae gi) to a ditch (Dorang) It is noteworthy that the East-sea salt production method was not selecting a method of a salt-pond style with a bank for salt production but using the salt water transportation fashion without a bank for that. Judging from these facts, we can consider that traditional salt production method was handed down into the Yi-dynasty from ancient times.
