Some inscribed bricks excavated from the western region of North Korea have been found bearing an era name used after 314 when the Nangnang and Daebang Commanderies had been completely ousted from the region. Others have been found with an era name used in the early fifth century. This indicates that the tradition of constructing brick chamber tombs was sustained for a century after the disappearance of the two commanderies. However, brick chamber tombs were never adopted as a burial system for the ruling class of the Goguryeo Kingdom. The Tomb of Jang Mui built in 348 and the Tomb of Dongni built in 353 both departed from the typical brick chamber tomb style of the region, and elements associated with stone chamber tombs were added to them. The Tomb of Dongsu (Anak Tomb No. 3), which is similar to the other two tombs in that its occupant is of Chinese descent, was constructed in 357 not as a brick chamber tomb, but as an earthen mound tomb with a stone chamber. Still, the continuation of brick chamber tomb tradition in the next half century has been somewhat puzzling. Although dated inscribed bricks have served as important evidence for understanding the continuation of the brick chamber tomb tradition, there has been a problem of continually repeating previous studies. It has also been pointed out that there was an error in the interpretation of era names in some of the dated inscribed bricks that had been believed to have been produced in or after 357. For example, "second year of Taean" (Taian in Chinese), which had been understood to correspond to 386 (during the Former Qin Dynasty), in fact refers to 303 (during the reign of Emperor Hui of the Western Jin Dynasty). In the case of "first year of Geonsi" (Jianshi in Chinese), which had been believed to indicate 407 (during the Later Yan Dynasty), it actually refers to 301. "Geonsi" is the era name used during the period when Sima Yun ousted Emperor Hui of the Western Jin Dynasty and briefly occupied imperial throne. Outside these two cases, the remaining dated inscribed bricks thought to have been produced in or after 357 are those dated to the "third year of Wonheung" (Yuanxing in Chinese). However, a reexamination of these bricks reveals that what is really "Yeongheung" (Yongxing in Chinese) has been misread as "Wonheung." The third year of Yeongheung corresponds to either 306 during the Western Jin Dynasty or 352 during the Later Zhao Dynasty, but it is highly probable that it refers to 306. This means that there is no conclusive evidence to support the hypothesis that brick chamber tombs were built in the area until the late fourth century and even into the early fifth. Accordingly, the Tombs of Jang Mui and Dongni should be viewed as the latest known brick chamber tombs to be constructed in the western region of North Korea. Moreover, brick chamber tombs appear to have been no longer built in the area around the time when the Tomb of Dongsu was constructed. These speculations accord with the historical circumstances of the time.

As of July, 2009, Chungnam Province get DI (Direct Investment) of 2,502 corporations as the amount of 31 billion US dollars only for 3 years. Especially, Chungnam provincial governor make a excessive performance of 2.5 times comparing to the target number, 1,000 of inviting capital, that is public promise in the election. Now, the amount of inviting foreign capital is 1.2 billion dollars, at the end of this year it might be 1.4 billion dollars just in case of making a success on going negotiations. This outstanding performance comes from governor's leadership and aggressive strategies of well-trained subordinates. Chungnam Province has nation-wide multiple targets focused on interdisciplinary industries including strategic industries of display, auto-parts, steel, and oil-chemistry. Also, it has organic network system based on the very descriptive and accurate informations managing the task force team consisted of 35 competent members. In conclusion, the core competence of inviting foreign capital in a regional government is governor's strong leadership, activated organization consisted of specially well trained subordinates, and predominant differentiated strategies in details.

Over the years(1971 to 1987), only 20 Korean film production companies had been granted the exclusive rights to make Korean films in Korea and to import foreign films with a quota system. They had been making trashy Korean movies to secure import quotas of foreign films. Newcomer's entry of market had also been limited and the growth of Korean films through innovation had been hampered. In the same period, The annual number of Rookie director is 10, the portion of debut films of all Korean films is 10.62%, and the audience portion of debut is only 10.5% of Korean movie audience. From 2004 to 2016, total number of rookie directors is 874, and 61.72% of 1,416 directors who made his debut over the 46 years from 1971 to 2016. This is far more than the number of directors who debuted for the last 32 years. From 2004 to 2016, the annual number of rookie directors is 62.15 and their debut film occupies 39.58% of the total amount of Korean movies released and 32.8% of the audience number. Since the full opening of the domestic market to foreign films industries in 1988, the liberalization of independent film production in 1999, as a result of innovation of a competitive system, the Korean movies have been loved by audiences. However, there are concerns that the decline of the screen quota in 2006, the monopoly of the 4 major distributors, increase in indie movies and Semi-adult movies for VOD, could be the potential threat for future innovation in Korean cinema.

The purpose of this study was to examine usefulness of KEDI-Individual Basic Learning Skills Test as a diagnostic tool of learning disorders(LD). Learning disorder group consisted of two subgroups, verbal learning disorder group(VLD, n＝34) and nonverbal learning disorder group(NVLD, n＝14). Comparison group consisted of Dysthymia Disorder subgroup(n＝11) and Normal subgroup(n＝20). Performance of intelligence test and achievement test was examined in all 4 subgroups. In KEDI-WISC, VLD subgroup revealed primary problems in vocabulary, information and verbal-auditory attention test. NVLD group revealed primary problems in almost all performance tests such as visual acuity, psycho-motor coordination speed and visual-spatial organizations ability subtest. In KEDI-Individual Basic Learning Test, VLD group revealed primary problems in phonological coding process, word recognition and mathematics. For successful classification of LD children, the importance of achievement test and intelligence test was discussed by discriminant analysis and factor analysis. The results indicate that KEDI-Individual Basic Learning Skills is of considerable usefulness in diagnosing LD, but must be used in subtests, and additional tests must be conducted for thorough exploration of LD.

The analyzed results of observed precipitation and its pH in Kwangiu for 262 days from fan. 1, 1991 to Dec. 31, 1995 are as follows. The annual mean pH was 5.7, and the monthly mean pH values of January-May and November were less than 5.6 in Kwangiu. The ratio of acid rain for these periods was about 48.1%, almost half that of the total observed days. In March, the pH was 5.4 and the ratio of acid precipitation was 69%, an especially serious situation. In the spring, the pH value was 5.5, thus weakly acidic. The pH of precipitation tended to decrease with greater precipitation. The relation between persistent time and pH of precipitation is variable, but if the persistent time is long, the pH is constant and low. It is fortunate that there is an increasing trend of pH in interannual variation, but it is thought important that the amplitude of variation of pH in 1995 was high and the pH value was 4.1 in October and November. Because heavy and persistent precipitation effects the accumulation of acidity, more concern about acid rain is needed.

The Uniform Customs and Practice for Documentary Credits (UCP) is a set of rules on the issuance and use of letters of credit. Historically, the commercial parties, particularly banks, have developed the techniques and methods for handling letters of credit in international trade finance. This practice has been standardized by the ICC (International Chamber of Commerce) by publishing the UCP in 1933 and subsequently updating it throughout the years. The ICC has developed and moulded the UCP by regular revisions, the current version being the UCP600. This latest version, called the UCP600, formally commenced on 1 July 2007. During the revision process, notice was taken of the considerable work that had been completed in creating the International Standard Banking Practice for the Examination of Documents under Documentary Credits (ISBP), ICC Publication 745. This publication has evolved into a necessary companion to the UCP for determining compliance of documents with the terms of letters of credit. It is the expectation of the Drafting Group and the Banking Commission that the application of the principles contained in the ISBP, including subsequent revisions thereof, will continue during the time UCP 600 is in force. This paper focuses on documents including various certificates, Packing List, Weight List, Beneficiary's Certificate, Analysiis, Inspection, Health, Phytosanitary, Quantity and Quality Certificates, Courier Receipts, Shipping Advice etc. and suggests some implications in the field.

The general programming channels, newly introduced around the beginning of the 2010s, have grown into powerful journalistic agencies, the far-reaching social influences of which are not confined by the economic effects within the South Korean media industry. They are now rendered to become part of major socio-political institutions that try to secure their privileges based on broadcast journalism, and to widen their business opportunities through those special kind of social practices. This research has taken a path of theoretical endeavour to devise a conceptual framework that will effectively lead to a series of academic investigation into the socio-political characteristics of general programming channels. To this end, specific attention is paid to such theoretical and conceptual resources as the instrumentalization of media by the politics, the political sociology of media power, media-political parallelism, and the structural coupling between the political and the media systems. This paper suggests that general programming channels have emerged as a new interface that accommodates and actualizes the structural coupling between the two societal subsystems, and in the course of that, they undercut the vulnerable basis of media public sphere, effectively replacing it with entertaining media-political sphere constructed and managed by themselves. This sphere is where the media system's logic and the poltical system's logic are intertwined, simutaneously accelerating not only the mediatization of the politics but also the politicization of the media.

When cement grout is used for waterproofing of grounds, important roles are played by fluidity, particle size and bleeding. The most important element which determines their characteristics is the water/cement ratio of grout. Moreover in order to improve the efficiency of soil permeation, micro cement with a smaller average diameter is used in addition to ordinary portland cement. Besides the mixing ratio and cement diameter, the condition of ground is also of fundamental importance in the efficiency of permeation. In order to evaluate grout in terms of permeation ability into ground, we need a field test of grounting, which is cost and time consuming. In this paper we present a laboratory test method in which the suitability and efficiency of grouts are simply and more practically tested. In Korea neither a test standard nor devices are available to simulate grouting in a laboratory. We devised a grout injection equipment in which grouting was reproduced in the same condition with different materials, and suggested a standard for the production of specimens. Our tests revealed that the efficiency of injection increases with the water/cement ratio. We also found that more efficiently injected is the grout with the order of decreasing size; MS8000, micro cement, and ultra fine cements, and colloidal super cement.

Five different levels of Ethephon were treated on tobacco cultivar yellow Special A and Coker and harvested for curing. Changes in dehydration properties, yellowing, chlorophyll, nicotine, sugar and starch contents during the processes of curing were studied in order to justify feasibility of adoption an idea of 3-stage-curing method instead of the 5-stage. Ethephon-treated-tobacco leaves showed marked degradation of chlorophyll, greater dehydration and greater reduction in nicotine contents while little change in either sugar, starch and other chemical components. They showed also shorter hours of curing period allowing possible curing response at a relatively low temperature than those without treatment. Thus they undergo only 3 stages of flue-curing processes, yellowing, calor-fixing and vein-drying, and need 72 hours to finish curing, but the ordinary leaves need 100 hours for it.

Limited geochemical components have been detected in fluid inclusions from ore deposits in south Korea by non-destructive and destructive analytical methods. Review of fluid inclusion studies display that the homogenization temperatures and salinities are in direct proportion. W and Cu ore deposits tend to show higher homogenization temperatures and salinities than Au ore deposits. Abundant halite-bearing fluid inclusions from the Eonyang Granite producing precious amethyst crystals may indicate that the initial fluid originated from magma is highly saline as shown by the quartz from the granite. Raman Laser microprobe detected $CO_2$, $N_2$ and $CH_4$ in a gold deposit, while these components are hardly detected from other deposits, even though destrucive analysis has dectected $CO_2$, $N_2$, $CH_4$, $H_2S$, and $SO_2$ from most of ore deposits. Individual fluid inclusion shows quite different components. These results suggest that large numbers of fluid inclusions should be analysed by Raman Laser microprobe to gain reliable data. Halite-bearing inclusion is hardly found in fluid inclusions from epithermal gold deposits in south Korea. Geochemistry, homogeinzation temperature and salinity of fluid inclusions may be useful to apply for exploration to find a concealed orebody.
