Background: People who were born in different years, that is, different birth cohorts, grow in varying socio-historical and dynamic contexts, which result in differences in social dispositions and physical abilities. Methods: This study used age-period-cohort analysis method to establish explanatory models on healthcare expenditure in Korea reflecting birth cohort factor using intrinsic estimator. Based on these models, we tried to investigate the effects of ageing population on future healthcare expenditure through simulation by scenarios. Results: Coefficient of cohort effect was not as high as that of age effect, but greater than that of period effect. The cohort effect can be interpreted to show 'healthy ageing' phenomenon. Healthy ageing effect shows annual average decrease of -1.74% to 1.57% in healthcare expenditure. Controlling age, period, and birth cohort effects, pure demographic effect of population ageing due to increase in life expectancy shows annual average increase of 1.61%-1.80% in healthcare expenditure. Conclusion: First, since the influence of population factor itself on healthcare expenditure increase is not as big as expected. Second, 'healthy ageing effect' suggests that there is a need of paradigm shift to prevention centered-healthcare services. Third, forecasting of health expenditure needs to reflect social change factors by considering birth cohort effect.

The Hebrew word for silk, meshi, is mentioned in the Bible only once and there is a possibility that the item to which it referred was made of local wild silk. Although Jewish historical sources from the Roman and Byzantine periods mention silk many times, only a few silk textiles have been discovered at a sited dated to the Byzantine period (4^th-7^th centuries CE). The word "silk" occurs in the New Testament, although only once. A turning point in the history of the Negev (Southern Israel) occurred around 400 CE when it underwent a period of prosperity related to the advent of Christianity and pilgrimage, which enabled the purchase of imported silk textiles. The Early Islamic period (7-8th centuries CE) yielded four (out of 310) silk textiles from Nahal 'Omer on the Spice Routes joining Petra, in the Edom Mountains of modern Jordan, and the mercantile outlets on the Mediterranean Sea, notably Gaza and El Arish. The most important silk textile assemblage in the Southern Levant was found near Jericho at Qarantal Cave 38 and dates to the medieval period (9th-13th centuries CE). Linen textiles decorated with silk tapestry originating in Egypt date back to the 10-11th centuries CE. Mulham textiles - silk warp with hidden cotton wefts - were discovered in the medieval fortress on Jazirat Fara'un (Coral Island) in the Red Sea, 14 kilometers south of Elat and today located in Egypt. Mulham is mentioned in literary sources of the ninth century in Iraq and Iran, whence it spread through the Islamic world. The article will present aspects of the origin, transmission, and exchange of these textiles.

This paper employs stochastic processing techniques to analyze explosion risks in plant facilities based on explosion return periods. Release probability is calculated using data from the Health and Safety Executive (HSE), along with annual leakage frequency per plant provided by DNV. Ignition probability, derived from various researchers' findings, is then considered to calculate the explosion return period based on the release quantity. The explosion risk is assessed by examining the volume, radius, and blast load of the vapor cloud, taking into account the calculated explosion return period. The reference distance for the design blast load model is determined by comparing and analyzing the vapor cloud radius according to the return period, historical vapor cloud explosion cases, and blast-resistant design guidelines. Utilizing the multi-energy method, the blast load range corresponding to the explosion return period is presented. The proposed return period serves as a standard for the design blast load model, established through a comparative analysis of vapor cloud explosion cases and blast-resistant design guidelines. The outcomes of this study contribute to the development of a performance-based blast-resistant design framework for plant facilities.

This article aims at investigating the origin of 'gookmin', which is currently working as the dominant discourse and leading identity in the South Korean society. Like 'nation', 'people' or/and 'citizen', the term of 'gookmin' is a very much particular and historical outcome of the colonial modernity. Nevertheless, however, there have been not so much serious socio-linguistic, cultural-political studies about its root. It is theoretically as well as practically quite important to trace back the birth of 'gookmin', which is working as an ideological, epistemological frame in/between subject and reality. In this regard, this article will consider the late Japanese colonial period as a key period of the birth of 'gookmin'. It will then critically scrutinize how the total mobilization system by adopted the colonial government has formed the discourse and subjectivity of 'gookmin' based on various physical apparatuses. By revealing that a totalistic nation/state of Japanese colonialism is behind 'gookmin', which wanted to mobilize every individuals into a so-called article of empire, this article tries to show the fascist and propaganda nature of 'gookmin' continuing even after the liberation. As a historical-materialist work of deconstruction the dominant discourse of 'gookmin', this study will basically take a cultural studies approach.

This geographical study is to identify the reality of Nokdun island which was once settled and farmed by our ancestor, but currently the island is do facto under Russia's control. Various historical documents including old maps, current large scale maps and satellite images besides field work were used for full analysis. According to historical records, up until Chosun Dynasty, Nokdun island in the lower Tuman river was one of the frontier fortified base crossed the river for the northern defense as well as seasonal farming for the farmer of Kyounghung border area. Even though the island was unjustly lost to Russia by the Beijing Treaty in the late Chosun period, the whole area of Nokdun was occupied and farmed by sole Koreans until the deportation by Stalin was forcibly measured. In these days due to the change of Tumn river channel and new deposition by river it became very difficult to find the original shape of Nokdun island. However, through intensive field works based on historical records, the research team found out the existence of the old wet-dry fields, old rural farmhouse remnants, and small and medium size of millstones that are supporting the reality of the island. Especially, the team traced a mud fortress presumedly built in the early Chosun period. We believe it might allow to allocate the exact location of Nokdun island in near future.

This is an analytical study on Munheongak (文獻閣) and it's catalogue. The major objective of the study is to get a recognition of Munheongak under the culture of Sukjong (肅宗) period in Korean library history. Most of early studies made on such a category have been concentrated on Jiphyunjeon (集賢殿), Hongmungwan (弘文館), Kyujanggak(奎章閣) and their backgrounds. In this study, the author has invest gated Kungwolji (宮闕志), Munheongakseomg (文獻閣書目) and other materials related to this subject. The findings of the study can be summarized as follows: 1. Munheongak was established by king Sukjong in the 26th year of his reign. According to some records of Kungkwolji, the reason of establishment of the library was to arrange the collection in the Sango (相庫) consisted of various kinds of materials. In case of books, most of them turned out to be Korean books. 2. Munheongak was sited to the estern side of Kyunghyundang (景賢堂), which was located on the Kyungdeokgung (慶德宮). After Youngjo (英祖) the place was called Kyungheuigung (慶熙宮) so as to avoid the name of the precedent king. But these days, both the buildings are not to be found. 3. After its establishment, the library could not play the role as a library because of the then political situation and sectionalism. During the period of the revival of the learning from Youngjo till Jeongjo(正祖) the function of the library was in a stagnant state. Kyujanggak played the part in its place. 4. Referring to the collection management, the Munheongakseomog is equipped with 101 titles, 2,525 volumes, which are arranged by means of the traditional Chinese classification system. 5. The classification scheme is based on the traditional Chinese classification system which might divide all subjects into four categories such as: Confucian classics division, Historical documents division, Master's division, and Collection of literature division. Some illustrations reveal that the classification system was directly influenced by Seogoseomg (書庫書目) : the influence reflected in the classes for the translated literature and writings, poems, genealogy about kings, etc. But some subdivisions such as a class of Annals, Historical Epcerpts were omitted in the classification scheme, which did not strike the balance in the system in terms of the present theory of classification. Most of bibliographical descriptions were also influenced by Seogoseomog but some elements were partly omitted. 6. The special feature of the collection building is the absence of books in Collection of literature division except only three kinds of books in examining the Munheongakseomog. Since this is rather a comprehensive study for such aspects as historical backround, catalogue, and cultural environment of Munheongak and its related record, it is advised that further and additional research should be made.

This study aims to investigate droughts from the magnitude perspective based on the SPI (Standardized Precipitation Index) and the theory of runs applicable to quantitative analysis of drought in South Korea. In addition, the dry spell analysis was conducted on the drought history in the five major river basins of South Korea to obtain the magnitude, duration and severity of drought, and the quantitative evaluation has been made on historical droughts by estimating the return period using the SDF (Severity-Duration-Frequency) curve gained through drought frequency analysis. The analysis results showed that the return periods for droughts at the regional and major river basin scales were clearly identified. The return periods of severe drought that occurred around the major river basins in South Korea turn out to be mostly 30 to 50 years with the years of the worst drought in terms of severity being 1988 and 1994. In particular, South Korea experienced extremely severe droughts for two consecutive years during the period between 1994 and 1995. Drought in 2014 occurred in the Han River basin and was evaluated as the worst one in terms of severity and magnitude.

The Mireuk Temple Stone pagoda is the largest scale of the existing Stone Pagoda in Korea. A research until now postulates that the Stone pagoda at Mireuk Temple site is composed of nine stories total. However it does not have any records of the detail, dimension, and related methods, etc, even though it is a tectonically large scale building. Only one source of the description is based upon a story which is a sort of Korean myth or traditional story (Samkukyousa, Mu dynasty), although a historical description from a myth or a story is a polemical issue and still needed research in order to prove the truth. One of the ways to make a proof of the truth is an architectural research from the typology of the plane. The types of the plane are differentiated from each era. Therefore, the typology of the plane presents a reason or a proof for the age of the pagoda. Furthermore, the typology of the plane is crucial part in the research of the historical style and it could help the historical style of the Mireuk temple stone pagoda. Research until now shows that the Mireuk temple stone pagoda is the genesis of the stone pagoda shaped after wooden one. It is impossible to find any previous one from the stone pagoda at Mireuk Temple site in Korea. So it is easier to find any previous example from the history of China because Buddhist pagoda-most pagodas are something to do with Buddhism-in Korea is introduced by India via China. This research presents the periodical variation of stone and brick pagoda in both countries. It concludes that the Mireuk temple stone pagoda has $7^{th}$ century's plane type.

This study examined dahoe(多繪-braided cord) and mangsu(網綬-ornament of husu for ceremonial dress) used in myeon gwan(冕冠), daedae(大帶), and husu(後綬) among royal formal dresses in the Joseon Dynasty(1392-1910) based on historical materials including literature, relics, and paintings. The results of this study are as follows. In myeon-gwan, dahoe was used for cap strings, goeing(紘) and yeong(纓). Cap strings were applied to the king, the Crown Prince, and the eldest son of the Crown Prince regardless of their status, and they showed differences among the periods. Both goeing and yeong were used during the early period of Joseon, and then only yeong was used in the late period. As goeing was removed and only yeong was used in the late period, patterns combining goeing and yeong, in color and wearing method, appeared. Dahoe used in cap strings is dongdahoe(童多繪-a kind of braided cord). In daedae, 'nyuyak(紐約)' was tied up to its fastening part. The material of nyuyak was changed from dongdahoe in the early Joseon Dynasty to guangdahoe(廣多繪-a kind of braided cord) in the late period, and the method of using it was also changed. Husu was imported from Beijing in China during the early period of the Joseon Dynasty, but in 1747, it was regulated to be woven in Joseon, and at that time, King Yeongjo attempted to restore the institution of weaving husu with "320 su(首)," namely, 6,400 strands as specified for the status of a prince of the Ming Dynasty.

This article is purposed of reviewing the development history of Japanese dental devices and instrument, and their related advertisement activities during the Japanese colonized period in Korea in early 20th century. Japanese dental devices and instrument were redesigned to accommodate their ergonomic shape above the simple imitation, and it implies the excessive desires brought them frustrations. The tragic earthquake on Sep. l, 1923, medical insurance law enforcement on Jan. 1, 1927, celebration of "Cavity prevention Day" started on Jun. 4, 1928, and the attack of Manchuria and China by Japan after 1931, all of these historical incidents become the preliminary requirement for the development of dental devices. On Nov. 1, 1937, Japanese government started to control dental materials, driving the campaigns for excluding foreign products and encourging the use of local products. In 1939, Nakajima dental manufacturers used this political and social atmosphere on their advertisement as saying "Our Nakajima's products have no compromise with the short raw materials, but only commitment to our quality". Since after 1940, the price and supply have been strongly under control, and the control group was appeared to manage all of supply and distribution of raw materials, regular price system, and specifications. At last, the Japanese national power were devastated in its production and distribution capacities, and get to the frustrated period. The main advertised dental devices and instruments in Korea during the Japanese colonized period were 1) dental chair, unit and cabinet, 2) dental x-ray, 3) compressors, 4) dental needles, 5) small instrument and carryon medical(emergency) kit, 6) oral hygiene and pyorrhea alveolaris, infrared rays, sunlight lamp, ultrashort wave treatment devices, 7)crown former, electric furnace, casting machine, articulator, electric lathe, and laboratory equipments, etc.
