Songguk-ri site gained academic recognition by the excavation of stone coffin tomb with a bronze dagger in 1974. And it is confirmed that this site is epoch-making in Korean bronze age through the following excavation started in 1975. But the excavation reports published until now do not have even overall view of this site, thus it is difficult to get the whole picture of this site. Thus, in this paper the author reexamined all reports on this site and by making the map of overall view and distribution of archaeological features as a basic research. Moreover, I analyzed also artifacts from this site, and compared with the recent papers written by other researchers about the chronology and character. Songguk-ri site has livelihood domain which consists of dwelling pits, attached features, storage pits, pot-firing features, wood fence, abatises, buildings above ground, as well as cemetery which consists of stone-coffins, jar-coffins, pit tombs. Trace of making large terrace was also excavated. These features seem to belong to the same archaeological stage, dated about B.C.850-550, according to C14 dating. On the other hand, the intensification of wet-rice cultivation made this group more productive. Based on this financial strength, some influential group emerged they constructed defensive settlement to protect their products safely. Besides it seems that there were frequent occurrence of conflicts. However, we can know that they kept their stable life, through the expansion of living space. Consequently, Songguk-ri site played a role of the summit among some settlement in this area.
The Pulse diagnosis is in the boundary of the Four Examinations, and it is called 切診, or palpation. It has a great impact on people in reminding of the Traditional Medicine that it is probably the first thing that people think of when they hear about Traditional Medicine. Hu-Jun quoted in the Treasured Mirror of Eastern Medicine "東醫寶鑑" that the doctor finds out the deficiency and the excess of the meridian of the patiant through the pulse, and that it is of the utmost necessity to know the "deficiency and the excess" of the meridian to decide the formula (君臣佐使) of the herbal medicine and the acupuncture/moxibustion treatment. The research on the studies of pulse diagnosis have been concentrated on the origin, history, and the theory of the pulse diagnosis throughout the years; however, the number of research on the image from the classics on pulse diagnosis have been less. With this in mind, this paper was written to study more on the origin and the history of the pulse diagnosis as well as to study on the image of pulse diagnosis shown on the classics on Traditional Medicine in China and Korea. The history of the pulse diagnosis has its root on the attempt to find out what is happening inside the body through the indication of the small changes of the pulse that is shown on the outer boundaries of the body. There were various kinds of pulse diagnosis including "Three positions and nine indicators method" and "Carotid pulsation and wrist pulse method" in the ancient period, and wrist pulse-taking method became the most popular since the completion of studying on palpation by 初보. The image of the palpation helps the rudimentary practitioners of Traditional Medicine. They are divided into two large categories, which are the area of diagnosis and the shape of the pulse itself. The historical classics including the image of the pulse diagnosis can be found since the Song Dynasty of China. There are various kinds of image of pulse diagnosis in the classic such as "The picture of the hand meridian" from "脈訣指掌病式圖說", "The picture of the image of meridian" from "察病指南", "The picture of the Seven exterior and Eight interior" from "校正圖注脈訣", and "The picture of the six parts of meridian" from Treasured Mirror of Eastern Medicine "東醫寶鑑". The Treasured Mirror of Eastern Medicine "東醫寶鑑" have analyzed the basic theories and made up the standards of pulse diagnosis by establishing "The picture of the six parts of meridian" based on "The method of placing the viscera and bowels corresponding to cun-guan-qi, or the meridian".

This paper explores the triple helix innovation system in Food Valley in the Netherlands which is considered one of the most innovative food clusters in the world. The triple helix approach has been so far little tackled in the literature on innovation system and cluster. However, tills approach can be a useful tool for understanding the dynamic characters and knowledge transfer mechanism of industrial cluster. On the basis of an in-depth case study, we argue that Food Valley has evolved through four circles of growth in the triple helix innovation system. From the mid-2000s onward, it is seen that Food Valley has been on the stabilized circle in the triple helix system of innovation. Centered upon Wageningen UR, local universities and research centers play a pivotal role in building the triple helix innovation system. To cope with radical changes in markets and technology since the late 1980s, local firms have made a great deal of effort to reinforce the university-industry partnership. On the other hand, government agencies have played a critical role for establishing institutional milieu that facilitate university-industry partnerships and local knowledge transfer and spillover.

This paper describes the experiment that determines the ultimate strength of new uniplanar T-joints made of cold-formed square hollow sections. The new T-joint focused on the configuration of a branch member that is oriented 45 degrees to the plane of the truss and welded to the chord member whose web is stiffened with plate. The strength and failure mode are examined using the existing strength formula for the branch-rotated T-joint $(16.7{\leq}2{\gamma}(B/T){\leq}33.3$ and $0.63{\leq}{\beta}(b1/B){\leq}0.7)$. The test result shows that the capacity of the stiffened joint increases with thicker stiffening plate. The failure mode of the specimen $(2{\gamma}=33.3)$ is stiffened with plate changes from M2 (flange failure) to M3 (combined failure). On the other hand, the failure mode of the specimen $(2{\gamma}=16.7)$ is stiffened with plate changes from M1 ( web failure) to M2 (flange failure)
As increase the number of vehicles, the issue of greenhouse gas that was emitted by them became important. As a result, greenhouse gas (GHG) regulations are being strengthened and efforts are being actively made to reduce greenhouse gas emissions in the automotive industry. In the other hand, regulations for harmful emission of vehicles have been reinforced by step. Especially, the lastly applied step, so called Euro 6, not only decreased NOx limit down to half of Euro 5 but also introduced real driving emission limit for NOx and PN. It is a challenge for manufacturers to meet the recent GHG regulation as well as the latest emission regulation. To overcome these regulations a De-NOx after-treatment system is being applied to diesel vehicles that are known emitting the lowest GHG among conventional internal combustion engines. At the time of the introduction of Euro 6 emission standard in Korea, in the domestic fuel economy certification test, some diesel vehicles emitted more $CH_4$ than Euro 5 vehicles. As a result, it was confirmed that LNT-equipped vehicles emitted a high level $CH_4$ and the level exceeded the US emission standard. In order to determine the reason, various prior literature was investigated. However, it was difficult to find a detailed study on the methane increase with LNT. In this paper, to determine whether the characteristics of vehicles equipped with LNT the affects the above issue and other greenhouse gases, 6 passenger cars were tested on several emission test modes and ambient temperatures with a environment chamber chassis dynamometer. 2 cars of these were equipped with LNT only, other 2 cars had SCR only, and LNT + SCR were applied to remaining 2 cars. The test result shown that the vehicles equipped with LNT emitted more $CH_4$ than the vehicles with SCR only. Also, $CH_4$ tended to increase as the higher acceleration of the test mode. However, as the test temperature decreases, $CH_4$ tended to decreased. $CO_2$ was not affected by kinds of De-NOx device but characteristic of the test modes.

Recently, various connected industrial parks (CIPs) architectures using new technologies such as cloud computing, CPS, big data, fifth-generation mobile communication 5G, IIoT, VR-AR, and ventilation transportation AI algorithms have been proposed in Korea. Korea's small and medium-sized enterprises do not have the upper hand in technological competitiveness than overseas advanced countries such as the United States, Europe and Japan. For this reason, Korea's small and medium-sized enterprises have to invest a lot of money in technology research and development. As a latecomer, Korean SMEs need to improve their profitability in order to find sustainable growth potential. Financially, it is most efficient for small and medium-sized Korean companies to cut costs to increase their profitability. This paper made profitability improvement by reducing costs for small and medium-sized enterprises located in CIPs in Korea a major task. VJP (Vehicle Action Program) was noted as a way to reduce costs for small and medium-sized enterprises located in CIPs in Korea. The method of achieving minimum logistics costs for small businesses through the Korean CIPs payment system was analyzed. The details of the new Korean CIPs payment system were largely divided into four types: "Business", "Data", "Technique", and "Finance". Cost Benefit Analysis (CBA) was used as a performance analysis method for CIPs payment systems.
Inlay (入絲), a poetic technique of digging grooves in the surface of crafts and decorating them with metal materials, was used throughout the royal daily routines, ceremonies and government officials of the Joseon Dynasty. The government-owned handicraft industry in the Joseon Dynasty was composed of craftsmen belonging to central and local government offices and was operated mainly by government-owned craftsmen. The inlay craftsman was transferred to the central government office and was in charge of inlay poetry for crafts. The current records of Korean inlay craftsmen are concentrated in the state-owned handicraft industry. In the state-owned handicraft industry, the government offices of inlay craftsmen can be divided into Kongjo (工造), Sangeuiwon (尙衣院), and the military. Here the election of a temporary government office for airspace is added. The government offices and military inlay craftsmen who use inlay crafts are assigned, and the inlay craftsmen are placed separately in the temporary office where the fine division of labor is developed. It can be made by utilizing craftsmen. The operation of these production systems was indispensable in pre-modern Korean society, where crafts had to be produced by hand. In this paper, we investigated the roles and job types of craftsmen in the state-owned handicraft industry during the Joseon Dynasty, focusing on inlay craftsmen. Although the details applied to the characteristics and materials of the field, labor supply and demand, etc. are different, Korea pursued crafts for various purposes through craftsmanship within the framework of the basic state-owned handicraft policy . The institutional equipment for implementation was almost common. We believe that adding and analyzing some literature records and relics will help us to study the crafts of the Joseon era in more detail.

In these days, there are various uses of Linux such as small embedded systems, routers, and huge servers, because Linux gives several advantages to system developers by allowing to use the open source code of the Linux kernel. On the other hand, the open source nature of the Linux kernel gives a bad influence on system security. If someone wants to exploit Linux-based systems, the attacker can easily do it by finding vulnerabilities of their Linux kernel sources. There are many kinds of existing methods for lading source-level vulnerabilities of softwares, but they are not suitable for finding source-level vulnerabilities of the Linux kernel which has an enormous amount of source code. In this paper, we propose the Onion mechanism as a methodology of finding source-level vulnerabilities of Linux kernel variables. The Onion mechanism is made up of two steps. The Int step is to select variables that may be vulnerable by using pattern matching mechanism and the second step is to inspect vulnerability of each selected variable by constructing and analyzing the system call trees. We also evaluate our proposed methodology by applying it to two well-known source-level vulnerabilities.

The DAPA (Defense Acquisition Program Administration) has been operating the DQ mark certification since 2012 to certify the superior technology and quality of munitions. On the other hand, the current DQ mark certification can not directly provide DQ mark certification to software because it is impossible to verify the quality of software alone. Therefore, this study analyzed domestic/overseas software quality evaluation/certification standards to find a way to verify the quality of software in the DQ mark certification. Among them, the method of applying the GS certification according to the international standard ISO/IEC 25000 series to the DQ mark certification was suggested as an improvement plan, and DQ mark certification verified the quality of software and provided certification. An attempt was made to expand the certification scope of DQ mark certification. This paper proposes that the DQ mark can be given to the system software by introducing GS certification to the DQ mark certification. To this end, an improved procedure for omitting the factory audit and verification by submitting a GS certificate for product evaluation is proposed. This is expected to increase defense exports using the granted DQ mark and improve the quality of defense software products through GS certification.
It is generally acknowledged that Philippines politics has achieved a basic soil for democracy at the macro-level by the two incidents of 'People Power' (1986 & 2001). However, in spite of such an achievement, Philippine politics at the micro-level, does not enjoy the same reputation. Institutionalized 'Bossism' or 'patron/clientelism' political culture has been attributed to make such a gap. This paper aims to bridge the gap by a longitudinal observation on local politics of a particular province in the Philippines. Surigao del Norte is the province picked up for the study. The reason why this particular province attracts special concerns is that there appears to come a very dynamic local politics, led by an indigenous Christian organization, the PBMA (Philippines Benevolent Missionary Association), which was founded in the mid 1960s. With the coming of the organization in the province, the political power of the traditional families has been narrowed. On the other hand, new families, not only the leader family of the PBMA but also the family allied with the PBMA, has expanded political influence. Following steps are adopted to understand the meaning of such a change. First, institutional frame of Philippine politics and elections will be reviewed. Second, demographic changes will be investigated on Surigao del Norte province to find out how popular the PBMA organization is among the people. Third, local election outcomes will be examined to describe the changing nature of political landscape of the province. This will reveal how the relationship between the old and new families has been developed in the province. Lastly, based on the facts discovered by a longitudinal observation, an attempt to evaluate theories on Philippines politics will be made Conclusions are as follows. To understand the dynamics of Philippine politics, 'expectations from the below,' or, 'passions of the people,' suggested by Ileto, needs more attention. Furthermore, 'mutual accommodation' between domination and resistance, coined by Abinales, also demands more appreciation. The case of local politics in the Surigao del Norte, with the coming of the PBMA, is sure to show a concrete example of changing politics in the 'changeless land.'
