We conducted phylogenetic analyses using multiplexed inter-simple sequence repeat genotyping by sequencing and compared chloroplast DNA sequences among Ardisia japonica, A. pusilla, and morphologically intermediate plants found on Jeju Island, Korea. Our network analysis demonstrated that the intermediate plants were genetically positioned between A. japonica and A. pusilla. Our comparison of the intergenic spacer between the psbA and trnH genes in chloroplast DNA indicated that four nucleotide substitutions separate A. japonica and A. pusilla, whereas the intermediate plants exhibited the A. japonica haplotype. Our results suggest that the intermediate plants on Jeju Island represent a natural hybrid of A. japonica, as the maternal species, and A. pusilla, and that they are attributable to Ardisia×walkeri. This record constitutes the first documented occurrence of the hybrid taxon in Korea.

A dimensioning system in a manufacturing process is often complex, especially when a lot of operations are involved in the process. Determination of operational dimensions and tolerances becomes even more complicated if there exist inconsistencies between operational and design relationships among operational dimensions in machining. This chart furnishes a record of the relationships in an easy-to-grasp form, proves that sufficient stock for a cut is available even under adverse conditions, and also proves that separate operations, when taken together, will harmonize as desired. In this paper, various existing roles of the chart have been extended to an operational routing sheet by generating it automatically, providing machining conditions, and verifying operational tolerances.

This study was to suggest the construction of work and expression authority records for FRBRization. ICP, FRBR/FRAD and RDA as the content rules were referred as the framework for the construction of work and expression authority records. LC RDA authority records examples, JSC of RDA authority examples, and VIAF work and expression authority records were analyzed as case studies. 5 findings were suggested. First, authority records consist of name, work, and expression authority records which are inter-related. Second, the construction of authorized access points was suggested according to 5 work types. Third, the consideration in describing work attributes as separate element and as part of an authorized access point, and other distinguishing characteristic of the work were suggested. Fourth, the consideration in describing expression attributes as separate element and as part of an authorized access point, and other distinguishing characteristic of the expression were suggested. Fifth, 5XX was suggested for linking between work and expression. This study would contribute to revise KCR4.

The Asian summer monsoon has a profound social and economic impact in East Asia and its surrounding countries. The monsoon is basically a response of the atmosphere to the differential heating between the land mass of the Asian continent and the adjacent oceans. The atmospheric response, however, is quite complicated due to the interactions between the atmospheric heat sources, land-sea contrast, and topography, The occurrence of extreme summertime floods in Korea, Japan, and China in 1998 and 1999 has highlighted the range of variability of the East Asian summertime monsoon circulation and spurred interest in investigating the cause of such extreme variability. While ENSO is often considered a prime mechanism responsible for the unusual hydrological disasters in East Asia, understanding of the connection between ENSO and the East Asian monsoon is hampered by their dynamic complexities. Along with a recent phenomenon of weather abnormalities observed in many parts of the globe, Korea has seen its share of increased weather abnormalities such as the record-breaking heavy rainfalls due to a series of flash floods in the summers of 1998 and 1999, following devastating Yangtze river floods in China. A clear regime shift is found in the tropospheric mean temperature in the northern hemisphere middle latitudes and the surface temperature over the Asian continent during the summer with a sudden warming since 1977. Either decadal climate variation or climate regime shift in the Asian continent is evident and may have altered the characteristics of the East Asian summer monsoon. Considering the summertime rainfall amount in Korea is overall increased lately, the 1998/99 heavy rainfalls may not be isolated episodes related only to ENSO, but could be a part of long-term climate variation. The record-breaking heavy summer rainfalls in Korea may not be direct impact of ENSO. Instead, the effects of decadal climate variation and ENSO may be coupled to each other and also to the East Asian summer monsoon system, while their individual impacts are difficult to separate.

Administrative information dataset records produced by various systems designed for work are difficult to manage on a case-by-case basis, requiring separate procedures to identify and evaluate data-sets. Identified data set records are apprasal and transferred to the records management system or disposed of. In this process, sufficient records management elements must be reflected in the production system itself in order to adhere to the principles of record management. In this paper, the functional requirements of the production system to accurately identify and safely manage data-sets were derived and applied based on the case of the KR property management system. It is hoped that this research on functional requirements of production systems will be added to lead to the creation of standards for functional requirements of data set production systems.

Although a few years have passed since the importance of the public record management became the subject, the management of the minutes which is produced from the deliberation and decision-making process of an important policy relatively was been neglected the while. When institutionally inspecting at present, the minutes production is based upon Record Management Law, and the minutes opening is based upon Freedom of Information Act. Although the minutes must be made out according to Record Management Law, it is not well operated. So, the minutes formally is made out and there was actually the important minutes excepted from the management object. Opening of the minutes made by Article 9 of Freedom of Information Act has the problem that be used as a basis of dividing unfairly into closed opening because the reason of the closed opening is vague. This study analyzes the problem of production and opening of the current minutes. It also considers Sunshine Act in USA and suggests a institutional ways for production and opening of Korean minutes. We can think of two institutional ways for production and opening of the minutes. One is making a separate law like Sunshine Act in USA. The other is revising the existing laws. In reality it's very difficult to make a new law for minute production and opening. Therefore, the purpose of this study is to suggest the way for revising Record Management Law and Freedom of Information Act that include minutes related regulations. The record must be fundamentally produced and opened for a nation and people as public records is the records of the nation and people as well as an authority which produced those records. If the minutes is produced and opened from a institutional change through the revision of Record Management Law and Freedom of Information Act, the minutes can not only help the responsible administration to realize but be utilized to important historical records as a basis data of an important policy decision-making.

Digital broadcasting and digital CATV and IPTV will continue in the competition, regardless of how the content of the program was broadcast over the Internet distribution and the damage of piracy is also growing. Excellent quality of the content of the digital CATV sales of DVD and high-density storage media because there is no difference in content and quality is the problem of illegal distribution. However, users can record and reuse program in the position of the guaranteed rights, and the purpose of training in fair and illegal recording and distribution needs to be separate from it. In this paper using a digital certificate recorded by the user and the process to ensure the purpose of illegal distribution of pharmaceutical distribution system design and implementation of the program was broadcast.

Hylodesmum laxum (Candolle) H. Ohashi & R. R. Mill subsp. laxum was recorded from Korea. The species is widely distributed in S. E. Asia, but in Korea the plant was the first found in the evergreen forest of Seogwipo-si in Jeju-do. Hylodesmum H. Ohashi & R. R. Mill was raised as a separate genus recently based on Desmodium sect. Podocarpium Benth. Except for two species, all Korean species included in the former Desmodium are classified into the genus Hylodesmum. A key to and enumeration of the Korean species of Hylodesmum are provided.

This paper describes an automatic vowel sequence reproduction system for a talking robot built to reproduce the human voice based on the working behavior of the human articulatory system. A sound analysis system is developed to record a sentence spoken by a human (mainly vowel sequences in the Japanese language) and to then analyze that sentence to give the correct command packet so the talking robot can repeat it. An algorithm based on a short-time energy method is developed to separate and count sound phonemes. A matching template using partial correlation coefficients (PARCOR) is applied to detect a voice in the talking robot's database similar to the spoken voice. Combining the sound separation and counting the result with the detection of vowels in human speech, the talking robot can reproduce a vowel sequence similar to the one spoken by the human. Two tests to verify the working behavior of the robot are performed. The results of the tests indicate that the robot can repeat a sequence of vowels spoken by a human with an average success rate of more than 60%.

balance and to estimate daily energy requirement in 43 Korean female college students maintaining their usual diet and activity level. Energy intake and expenditure were measured in two separate periods about one month apart, each period lasting for 3 days. All the subjects participated in both periods. Energy intake was assessed by two methods ; weighed diet record and duplicate portion analysis of diet minus fecal and urinary excretion. Mean daily energy intake level calculated from diet records was 28.5 kcal/kgB.W(1, 476 kcal/day), and similar to the level of 27.8 kcal/kgB.W(1, 438 kcal/days) obtained from the chemical analysis of duplicate portions. Mean daily energy expenditure, calculated from activity records of each subject, was 34.6 kcal/kgB.W, or 1.39 times BMR, which corresponds to light activity level. Mean daily energy balance of subjects was -5.9 kcal/kgB.W. Mean daily requirement of energy, calculated from the activity records of the subjects, was 34.6 kcal/kgB.W, similar to the level of the Korean RDA for light activity level. The results of this study indicate that 1) the activity level of the study subjects corresponds to the sedentary level ; 2) present Korean RDA for energy for light activity is adequate for the subjects ; and 3) the subjects should increase their energy intake since they are largely in negative energy balance.
