Recently, the valuation of patented technology has been greatly emphasized, and patent citation has been accepted as a very useful index of this technology. In this study, we performed correlation analyses between the patent citation counts and 17 explanatory variables of morphological, technological, and conceptual factors with a test dataset of U.S. patents in five subject fields. Seven variables having 5% or more standardized variances($r^2$) with patent citation counts were identified; number of pages, number of claims, reference-average-citation rate, patent increase/decrease rate, strength of bibliographic coupling, co-citation counts and document similarity. The result of the ANOVA test shows that the mean values of these variables vary among most subject fields.

The purpose of this study is to examine the perception of RDA by university library librarians and the level of perception of emotions, familiarity, understanding, introduction, obstacles, and education, and to secure basic data to improve awareness. The data needed for the study were obtained through a survey of 76 librarians in 4-year university libraries. As a result of the survey, 67.1% of librarians had listened to RDA, and school classes were the highest at 51.0% of cognitive means. Second, librarians perceived that they were more positive emotions than negative emotions about RDA, and that they were not familiar with RDA-related principles or concepts. In particular, it was recognized that the RDA itself and FRAD were not more familiar. The librarian recognized that they understood RDA-related principles or concepts at a normal level, and in particular, recognized that they did not further understand the authority and encoding. Third, librarians recognized the introduction of RDA at a slightly higher level than usual, but among the questions, 'RDA replaces AACR2' was recognized at a normal level. The librarian recognized the obstacles to the introduction of RDA at a higher level than usual, and in particular, the lack of education related to RDA was highly recognized. Fourth, librarians recognized the need for RDA-related education at a high level, especially the use of RDA Toolkit, changes in RDA records, differences between RDA and AACR2, and the need for RDA and MARC21-related education. In this study, based on the research results, a plan to improve librarian awareness of RDA was proposed.

The rate of single-person households has been increasing all over the world, and there has been a particularly rapid increase in them in Korea. Single-person households show unique and various characteristics related to the reasons for becoming a single-person household, gender, life cycle, and so on. Thus, research needs to focus on the specific groups of single-person households in order to provide tailored policies and programs. This study segmented single-person households in three groups based on life cycle: young, middle-aged, and older adults. Differences in the level of healthy lifestyle, as well as factors affecting that, were investigated according to the groups. The data were collected in 2022, with 237 respondents from single-person households in Kimpo. Descriptive statistics, t-test, ANOVA, and multiple regression analysis were conducted. The overall level of healthy lifestyle was found to be significantly higher for young adults compared to older adults. Results from multiple regression show that significant factors related to the healthy lifestyle of single-person households were gender, educational attainment, whether becoming a single-person household was voluntary, and whether the respondents had experienced discrimination as a single-person household. Significant factors differed by the sub-categories of the healthy lifestyle scale. This study has implications related to discovering differences in the level of healthy lifestyles of single-person households through examining the factors affecting it according to life cycle.

This study was to suggest display of RDA resource type in OPAC efficiently. Literature reviews and users test and preference survey were used as research methods. The 4 ways for the display of RDA resource type were suggested. First, GMD and the resource type code(bcode2) invented by library itself as well as leader/06, 007, and 008 field should be used for converting AACR2 resource type to RDA resource type in the bibliographic records. Second, RDA resource type vocabularies applicable to Korean cataloging environment should be designed and described in 33X subfield ${\blacktriangledown}9$ and detailed resource terms described in 34X should be also expressed in OPAC. Third, two option is suggested as content type and carrier type display separately and as content type and carrier type combination. Fourth, 336, 338 filed, leader/07 bibliographic level, 008/30-31 Literary text for sound recordings, 34X field were useful to develop user centered resource type icon. This study would be able to increase the utilization of RDA resource types and help the users to understand the RDA resource type in OPAC.

We described how to implement character expressions and animations that play an important role in expressing emotions and personalities in low-polygon character animation. With the development of the video industry, character expressions and mouth-shaped lip-syncing in animation can realize natural movements at a level close to real life. However, for non-experts, it is difficult to use expert-level advanced technology. Therefore, We aimed to present a guide for low-budget low-polygon character animators or non-experts to create mouth-shaped lip-syncing more naturally using accessible and highly usable features. A total of 8 mouth shapes were developed for mouth shape lip-sync animation: 'ㅏ', 'ㅔ', 'ㅣ', 'ㅗ', 'ㅜ', 'ㅡ', 'ㅓ' and a mouth shape that expresses a labial consonant. In the case of facial expression animation, a total of nine animations were produced by adding highly utilized interest, boredom, and pain to the six basic human emotions classified by Paul Ekman: surprise, fear, disgust, anger, happiness, and sadness. This study is meaningful in that it makes it easy to produce natural animation using the features built into the modeling program without using complex technologies or programs.

This study examines the living conditions and life satisfaction of single-person households according to their life cycle. The survey was conducted from August to October 2022, and respondents were single-person households from Kimpo, South Korea. The respondents were categorized to three groups namely, young, middle-aged, and older adults by life cycle, and items regarding their sociodemographic background, personal life, family relations, and life satisfaction were included in the analysis. Descriptive statistics, Chi-square analysis, analysis of variance, and multiple regression analysis were performed. The key findings were as follows. First, significant differences were found according to life cycle in the respondents' diet, clothing, housing, financial and home management, self-care, and leisure life. Second, the variables that significantly affected the level of life satisfaction of single-person households were the life cycle with young adults showing a higher level of satisfaction; having a family member to care; living alone voluntarily, discrimination experience; community awareness; and ties with the local community. Based on the results, it is clear that single-person households have different needs and problems in each stage of life cycle. Thus, to reflect the different experiences and needs of single-person households by life cycle, tailored policy and programs should be provided for young, middle-aged, and older adult single-person households.

Since 1966 when the Journal of the Korean Society of Oceanography was founded, more than 1,200 scientific papers have been published. Among them, papers for the biological oceanography constitute the largest portion of 37%, followed by the physical oceanography with 25%, and then the geological oceanography with about 17%. Papers on the chemical oceanography (CO) accounts for about 20% with around 250 papers. The field of the chemical oceanography generally occupied more than 20% since the first issue, but it declined down to 10% from the 1980s to the 1990s, and has regained to more than 20% since the late 1990s. Most of the CO research sites were at Korean coastal area, and 1/3 of the papers were on the South Sea, 1/4 on the Yellow Sea and another 1/4 on the East Sea. Nearly 60% of the CO papers were on seawater studies and about 30% on sediment studies. The main topic of the CO research was nutrients, followed by metals, isotopes, environmental pollution, organic pollution, organic matter, and gases. Most of the first authors belonged to the university, but the Korea Institute of Ocean Science and Technology (including the whole body) was the affiliation with the single largest group of the first authors.

In this study, the antioxidative effects of 50% ethanol extract, ethylacetate fraction and aglycone fraction obtained from dried whole plant of Solanum nigrum L. were investigated. The free radical scavenging activities ($FSC_{50}$) were $215.46{\mu}g/mL$, $42.43{\mu}g/mL$ and $52.28{\mu}g/mL$, respectively. Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) in $Fe^{3+}-EDTA/H_2O_2$ system were $25.25{\mu}g/mL$, $7.05{\mu}g/mL$ and $6.25{\mu}g/mL$, respectively. 50% ethanol extract and aglycone fraction showed the cellular protective effect against $^1O_2$ induced cellular damage of rabbit erythrocytes at $5{\sim}25{\mu}g/mL$, but not at high concentrations. These results indicated that S. nigrum extract/fractions could be used as an antioxidative agent. However, it could induce cellular damage at high concentrations. In conclusion, a special caution is required to use S. nigrum extracts as a cosmetic ingredient.
