This scientific article is devoted to the study of the legal significance of such a category of legal status of the purchaser of another's thing, as its good faith. The essence of this phenomenon has been studied, it has been established that the criterion of good faith attaches significant importance to the claims of the participants of these relations for the acquisition or preservation of private property rights. The paper emphasizes that, in addition to the importance of good conscience at the time of possession of another's thing, which gives legal certainty the possibility of registration of the title and is part of the actual composition for the acquisition of property or the right of ancient possession, bona fides also characterizes the behavior of the occupier. In this case, good conscience only has some legal consequences when it is opposed to subjective law. Under such conditions, it acquires direct legal significance, including as a condition for the acquisition and protection of rights. Good faith possession of another's property is an internal indicator of the subject's awareness of a certain property status. This sense, the article assesses this status from the standpoint of the scientific concept of the visibility of law. According to this theory, prescription is also considered as a consequence of the appearance of law, however, because it arises and lasts against the will of the parties and despite their awareness of this fact. Therefore, bona fide continuous and open possession of property as one's own, during the acquisition period, was most significantly associated with the appearance of property. Therefore, the concept of good faith, in the sense of personal perception of real values, is closely related to the principle of protection of the appearance of law, as it is aimed at understanding it by third parties. The paper notes certain differences in the application of the theory of the appearance of the right in the acquisition of property by a bona fide purchaser from an unauthorized alienator and the acquisitive prescription. It is emphasized that such a mechanism must be used in presuming the attitude to the thing as its own, by the holder of movable property. But there should be exceptions to the rule, in particular, if the owner has grounds for vindication of the thing.

The hydrogen attack characteristics of 3Cr-1Mo-V steel as simulated weld heat affected state were studied in this paper. The hydrogen attack susceptibility was evaluated by the ratios of Charpy impact absorbed energy at 0℃($vE_{0HA}$/$vE_{0}$) and reduction of area by tensile test ($RA_{HA}$/RA) before and after exposure to hydrogen at 600℃ under 450kgf/㎠ for 300hr. The values of $vE_{0HA}$/$vE_{0}$ and $RA_{HA}$/RA were aggravated as the peak temperature of the simulated heat affected zone(HAZ) raised. These results were due to the increase of the possession of bubbles along the grain boundaries, which were resulted in the reduction of grain boundary area to be precipitated carbides due to grain coarsening and the carbon dissolved in the martensite-austenite constituent near by the prior austenite grain boundary. The possession ratio of methane bubbles formed along prior austenite grain boundaries were increased with raising the peak temperature. (Received February 22, 2000)

The hydrogen attack characteristics of 3Cr-1Mo-V steel as simulated weld heat affected state were studied in this paper. The hydrogen attack susceptibility was evaluated by the ratios of Charpy impact absorbed energy at 0℃({TEX}$vE_{0} {HA}_/vE_{0}${/TEX}) and reduction of area by tensile test({TEX}$RA_{HA}/RA${/TEX}) before and after exposure to hydrogen at 600℃ under 450kgf/㎠ for 300hr. The values of {TEX}$vE_{0} {HA}_/vE_{0}${/TEX} and {TEX}$RA_{HA}/RA${/TEX} were aggravated as the peak temperature of the simulated heat affected zone(HAZ) raised. These results were due to the increase of the possession of bubbles along the grain boundaries, which were resulted in the reduction of grain boundary area to be precipitated carbides due to grain coarsening and the carbon dissolved in the martensite-austenite constituent near by the prior austenite grain boundary.

Bills of lading are crucial in international sales on shipment terms since they guard buyers against loss of or damage to the goods in transit by giving them the rights against carriers. A bill of lading, as document of title, gives the buyer the right to demand physical possession of the goods from the carrier and enables the buyer who is in possession of damaged or short-delivered goods to sue the carrier. In this context the buyer in sales on CIF or CFR terms or FOB terms with additional services benefits from the bill of lading which functions as a receipt of goods and a evidence of the terms of the contract of carriage. Protection of such buyer's interests can be provided in the sale contract through appropriate express or implied terms on the seller's documentary obligations: Which transport document, a bill of lading or a sea waybill, is required? Who should be named as the consignee in the transport document and, in case of bill of lading, by whom should the bill be endorsed? What should be stated in the bill of lading for the quantity of the goods? How about a bill of lading that contains so called "unknown clause"? How many bills of lading for the entire contract goods should be tendered? Can a bill of lading stating that the goods have been shipped in apparent good order and condition also state that the goods were damaged after shipment? This paper seeks to provide answers for these particular questions.

The present state of possesion of durable consumer's goods in on family in Korean is could be similar with that of about 25 years ago in Japan. Korea meet a period of high rate of economic growth, Japan had already experienced this 25 years ago. It would be important to predict and plan the storage space in the planning house since purchase of durable consummers' goods increase greatly as the rapid economic growth. In order to grasp the dweller's way of thinking and an attitude of living in small size house in Japan, questionaire owe prepared focusing on the "small space", possession of excess living goods and dweller's state of living. From the analysis of the answers for questionaire, the result is as follows. (1) Most of dweller's conclude that the reason of the disorder in their house is that their house in too small, so that they think the part of thier living goods must be disposed. This concept is also available even when they buy new living goods. (2) Disposal of living goods not in use, restraint of buying those are considered inevitable. In addition, changing of place of furnitures is also introduced. (3) The dweller living under 50m2 area dosen's not consider the disorder the house by the living goods. they have interest in how the tradition could be kept their home.

The study examined the socio-economic factors influencing the participation of rural farming households in barter trade in Ondo State, Nigeria. The objectives were to compare the socio-economic characteristics of the participants and non-participants in barter trade, analyze the preference for barter trade and identify the constraints to it. Also, the factors affecting respondents' participation in barter trade were identified. Empirical results indicated that there were significant differences in the socio-economic characteristics of the participants and non-participants in barter trade. The SWOT analysis showed that possession of agrarian attributes by the locality where the trade is practiced was the strongest factor ensuring the survival of barter in the study area. Double coincidence of wants was found to be the most prevailing weakness associated with barter while the major reason for participation by some households was that the quantity of commodities received is usually higher compared with cash transactions. Transportation cost to barter markets was found to be the greatest threat to the continued existence of barter trade in the area. The results of the Probit model showed that age, household size, transportation cost to cash markets, farm size, distance to barter markets, and formal education significantly affected the probability participating in barter trade.
