  • An Old document(Diploma) is a historical and unique record, so it must be collected, arranged, and preserved for research as soon as possible. Especially, for the effective use of the Old Document(Diploma), it is needed to arrange and describe the material systematically on the ground of modern archival theory. The Kyujanggak Archives in the Seoul National University has published 23 volumes of Old document(Diploma) material Old Document(Diploma). But they seem to cause the readers inconvenience, because the materials are classified and gathered only by genre, the titles or the orders of the materials are not standardized, and there is no description about the content of each Old document(Diploma). Jangseo-gak Library in The Academy of Korean Studies has also published the series of Old document(Diploma) material Old Document(Diploma) Collection. However the case is not different, since they are all mixed up with materials classified and gathered by genre, family, academy, or local school. And a great part of the materials have no titles and no description about the content of each Old document(Diploma), either. About the arrangement and description of the records, European and American archival science has established the theory of l)the principle of provenance, 2)the principle of original order, 3)levels of control, 4)collective description. These theories are valuable for the effective use of Old document(Diploma). On the viewpoint of the principle of provenance, Old document(Diploma) materials should not be classified by subject and genre, but by family and person. Then, the Old document(Diploma) materials, after collected by the unit of family or person on the viewpoint of the principle of provenance, should be arranged in their original order for more detailed arrangement and furthermore, for the work to find their relationship. This is so called the principle of original order. The hierarchical management of the Old document(Diploma) materials, for example, classifying by record group, sub-group, series, item and so on, is the concept of the levels of control, and comprehensive description of the each hierarchical structure is the concept of the collective description. Let's apply these archival theories to 34 pieces of the Chung, Man-Seok's material in the series of Old document(Diploma) material Old Document(Diploma). First, collect the Old document(Diploma) materials into Chung, Man-Seok's collection(the principle of provenance), which were scattered in the series classified by genre. Secondly, rearrange them chronologically(the principle of original order), and then we can find the comprehensive information about Chung, Man-Seok. For the hierarchical management of the Old document(Diploma) materials, we should establish a few concepts from the general, large group to specific, small item. The concepts can be organized as following; l)record group(Chung, Man-Seok record group) - 2)sub-group(personnel document, property document, family document, social activity document, political activity document, etc) - 3)series(gyoji-series, gyoseo-series, yuji-series etc. in the personnel document) - 4)folder(document with additions) - 5)item(one document). According to the the theory of the collective description, in the level of record group, there should be a collective description of Chung, Man-Seok's biography or a summary of record group. Similarly, there should be a collective description of a summary of sub-group in the level of sub-group and a summary of series in the level of series.

  • Two-dimensional infrared (2D-IR) spectroscopy can probe the fast structural evolution of molecules under thermal equilibrium. Vibrational frequency fluctuation caused by structural evolution produced the time-dependent line shape change in 2D-IR spectrum. A variety of methods has been used to connect the evolution of 2D-IR spectrum with Frequency-Frequency Correlation Function (FFCF), which connects the experimental observables to a molecular level description. Here, a new method to extract FFCF from 2D-IR spectra is described. The experimental observable is the time-dependent frequency shift of maximum peak position in the slice spectrum of 2D-IR, which is taken along the excitation frequency axis. The direct relation between the 2D-IR peak shift and FFCF is proved analytically. Observing the 2D-IR peak shift does not need the full 2D-IR spectrum which covers 0-1 and 1-2 bands. Thus data collection time to determine FFCF can be reduced significantly, which helps the detection of transient species.

  • A theoretical description and experimental demonstration of homodyne-detected two-color transient grating (2-C TG) signal are presented. By treating the coupled bath degrees of freedom as a collection of harmonic oscillators and using a short-time expansion method, approximated nonlinear response functions were obtained. An analytic expression for the two-color transient grating signal was obtained by carrying out relevant Gaussian integrals. The initial rising and decaying parts of the 2-C TG signal is shown to be critically dependent on the ultrafast inertial component of the solvation correlation function. The experimental results confirm the predictions of the theoretical model.

  • The genus Hypoxylon is a member of the Xylariaceae that has brown to dark brown and phaseoliform single cell ascospores with a conspicuous full germ slit. Hypoxylon truncatum differs from H. annulatum, it has conspicuous perithecial mounds, dark brown stromatal surface, and absence of enriched ostiola disc. The isolate of Hypoxylon, collected from Mt. Deuk-yu in Korea, is compared with similar taxa and described. The isolation of H. truncatum is compared with similar taxa, H. annulatum, with a precise description in the SEM level in Korea.

  • The genus Daldinia is a member of the Xylariaceae that has brown to dark brown and phaseoliform single cell ascospores with a conspicuous full germ slit. The isolate of D. childiae collected from Mt. Deuk-yu in Korea were compared with similar taxa, D. eschscholzii and D. concentrica.. Ascospores were $11{\sim}13{\mu}m{\times}5.5{\sim}6{\mu}m$ in size, light brown to brown, unicellular, ellipsoid-inequilateral, with dull round ends. Ascospore showed very faint ornamentation at ${\times}7.0k$ magnification. It is one of the main morphological characteristic Korean collection of D. childiae under SEM level and a main reason of reinterpretation of D. concentrica in Korea. Using KOH-extractable pigment color of stroma, D. concentrica that also has supported the SEM level investigation. Daldinia concentrica, having those characteristic recorded in Korea, should be renamed as D. childiae. However, the isolate will be the first record as D. childiae, having precise morphological description in Korea.

  • As a part of the research program 'Survey of freshwater organisms and specimen collection', freshwater samples were collected from Lakes Soyang and Chungju in 2016. Hundreds of bacterial strains were isolated from the samples and were identified based on 16S rRNA gene sequences. Among the bacterial isolates, strains showing higher than 98.7% sequence similarity with validly published bacterial species not reported in Korea were selected as unrecorded bacterial species. Based on 16S rRNA gene sequence similarity, 17 strains were identified as unrecorded bacterial species in Korea. The 17 bacterial strains were phylogenetically diverse and belonged to four phyla, seven classes, 13 orders, 14 families, and 16 genera. At generic level, the unreported species were affiliated with Caulobacter, Paracoccus, and Mesorhizobium of the class Alphaproteobacteria, Deefgea, Undibacterium, Chitinimonas, Inhella, and Sphaerotilus of the class Betaproteobacteria, Vibrio and Cellvibrio of the class Gammaproteobacteria, Sanguibacter and Clavibacter of the phylum Actinobacteria, Lactococcus of the phylum Firmicutes, Deinococcus of the class Deinococci, and Chryseobacterium and Flavobacterium of the phylum Bacteroidetes. The unreported species were further characterized by examining Gram reaction, colony and cell morphology, biochemical properties, and phylogenetic position. The detailed description of the 17 unreported species are also provided.

  • Purpose: The aim of this study was to analyze the effects of job characteristics on emotional empowerment in visiting health personnel. Methods: Subjects were recruited in ten community health care centers in one directorial area. Data collection was done using a self-report questionnaire. Job characteristics of visiting healthcare personnel were measured using the questionnaire developed by Kang (2006), based on Hackman & Oldham (1975). Emotional empowerment was measured using the questionnaire developed by Kang (2006), based on Spreitzer (1995). Results: First, the score of job characteristics was revealed to be 3.51 points the task significance was high, and the feedback was low. Second, the level of emotional empowerment was revealed to be 3.78 points the meaning was high, and the impact was low. Third, the prediction power of job characteristics on emotional empowerment was 34% autonomy, task identity, and task significance were identified as statistically significant predictive factors. Conclusion: The job characteristics of visiting healthcare personnel are highly correlated with emotional empowerment. Autonomy, task identity, and task significance are predictive factors of emotional empowerment. These results can be used to develop more effective job planning for increasing organizational effectiveness in visiting healthcare personnel.
