The purpose of this study was to examine the current staffing practices in public libraries and to analyze the relevance of legal standards of public library staffing. It analyzed the national library statistical data to obtain the national average staffing rate, reviewed related literature to understand the rationales that established the key attributes that construct the current legal standards, and compared the placement rates of the three standards, namely the current legal standards, Korean Library Association's standards, and IFLA staffing standards, to determine the optimacy of the legal standards. It found the current placement rate in the legal standard was only 18.2%, marking the lowest rates among the three compared standards, indicating the current legal standards being unnecessarily high. The study attributes the problem to the structure of the current legal standards that calculate the staffing size based on the building and collection size rather than service populations. The findings of this study suggest a revision of the current standard based on service population while retaining the minimum staffing of three librarians even the smallest public library unit.

Tanakius kitaharae and Glyptocephalus stelleri, belonging to the family Pleuronectidae, were very similar in external morphology not only during adult periods, but also during larval periods. In this study, we compared larval development and growth of the two pleuronectids species in detail. Fifty-eight specimens of T. kitaharae larvae and five specimens of G. stelleri larvae were collected from the East Sea, southern Korean Strait, and the adjacent waters of Jeju Island during 2014~2016, and were identified using morphological and molecular markers. Flexion larvae of T. kitaharae (10.23~16.77 mm total length, TL) and G. stelleri (14.33 mm TL) were similar in morphometrics, but can be distinguished by the melanophores in the fin membranes (present in the former vs. absent in the latter), and the melanophores at posterior margin of shoulder girdle (absent in the former vs. present in the latter). Postflexion larvae of T. kitaharae (17.12~24.92 mm TL) and G. stelleri (27.71~32.95 mm TL) differed in the number of melanophores on the mid-lateral caudal region (two in the former vs. five in the latter), and that on the dorsal and anal fin pterygiophores (five or six in the former vs. one row in the latter). Tanakius kitaharae and G. stelleri larvae differed in size at the beginning of metamorphosis. The left eye of T. kitaharae larvae between 23.13~24.92 mm TL reached the dorsal margin of the head while that of G. stelleri larvae between 38.66~42.67 mm TL did not reached yet.

The purpose of this study is to analyze the characteristics of the media contained in textbooks for students with disabilities based on the information processing model, and to find ways to utilize library materials for class improvement for them. To this end, the media included in the in-depth learning activities of the Korean language textbooks of the 2015 revised special education basic curriculum were analyzed. As a result of the analysis, it was found that students with disabilities received information mainly through vision, process information through understanding, and use language intelligence to produce results. Specifically, they accepts learning contents through illustrations and texts, processes the contents based on understanding such as reasoning and explanation, and then uses linguistic intelligence such as writing and speaking to produce results. Based on the results of this analysis, a practical method to utilize library materials in the Korean language class of students with disabilities was proposed as follows. Developing a variety of input mediums based on reading stages and collection mapping for students with disabilities. Providing book materials through reading and listening. Teaching appropriate methodological knowledge to self-directly solve advanced learning activities. In addition, developing types of writing and writing strategies that can help various production activities.

During menopause, elderly woman experience physical and emotional symptoms, including hot flashes, night sweats, weight gain, vaginal dryness, and mood swings. In this study, we investigated the effects of mixed herbal extracts containing Angelica gigas Nakai and Cuscuta chinensis Lam. on menopause symptoms in ovariectomized (OVX) rats. Daily oral treatments of 500 mg/kg and 1,000 mg/kg in OVX rats for 8 weeks significantly reduced weight gain, inhibited hepatic lipid accumulation, and lowered serum lipid levels comparable to the effects induced by estradiol treatments. Mixed herbal extracts (named Jaeummidan) also prevented vaginal dryness as measured by increased vaginal weight. Increased vaginal weight was associated with enlarged epithelium thickness. These data show the preventive actions of Jaeummidan against menopause symptoms and further suggest the possibility of developing functional ingredients in elderly human populations experiencing menopause symptoms.

This study is a survey of collection development policies in the 40 university libraries among 42 in Korea as of 1984. The survey used a questionnaire with 36 questions concerning the basic elements of the collection development policy. The survey results revealed many problems demanding correction. The measures to correct the problems in the university libraries are as follows. 1. It is desirable that the libraries should have a collection development policy statement written and adopted for the systematic collection building. 2. It is advisable that the libraries should include a function of the materials selection among other various functions of the Library Committee for the purpose of informing administrators of the goals of the libraries and the validity of the budgetary allocation. 3. It is desirable that each library should organize the Collection Development Committee for minimizing the possibility of personal bias on the part of the individual selectors. 4. It is advisable that the primary responsibility for materials selection should be delegated as follows: for the materials for faculty research, to the faculty members; for the other collections, to the professional staff of each department; for the final review of whether or not to purchase, to the Collection Development Committee. 5. It is desirable for the purchase priority of materials to be set up in accordance with the order of 6 levels of collection development. 6. It is advisable that the libraries should, as top priority, purchase materials in direct su n.0, pport of the undergraduate and graduate academic programs, and in subject matter areas other than languages and literature, Korean materials should have not only the higher priority than the foreign language materials, but also maintain the comprehensive collection level. 7. It is desirable that the special collections should be purchased by special funds from the authority, and the special collections librarian should have the responsibility of the materials selection under the advice of the faculty members relating to the subject area. 8. It is advisable that duplicate copies should be bought only for high use items, but for reserve books, by the program enrollment, and textbooks should not be bought in general, except as su n.0, pplemental materials for course work in which they are necessary and heavily used. 9. It is reasonable that the material budget should be distributed as follows: by the ratio for distributing funds, about 60-70% for the library and 30-40% for departments; by the type of materials, about 50% for books, 40% for periodicals and 10% for other materials, or when not bought other materials, about 50-60% for books and 40-50% for periodicals. In addition, it is desirable that undergraduate class enrollment, graduate class enrollment, undergraduate majors, graduate majors, average book cost in the discipline, number of faculty, and use rate by subject should be considered as the factors for the allocation of funds by department, and special consideration should be given to newly-founded departments so the library holdings can be adequate to su n.0, pport them.

In recent years, changes in the university libraries environment have led to increased emphases on improving or restructuring the organizational structures of university libraries. Technology, trends toward access over ownership, user focus, and restructuring in higher education are some of the major factors contributing to these changes. The users' new information retrieving behavior are emerged from the developments in information technology with new media and from the competitive research environments, and thus this trend has led to the gradual increase of collection arrangement by subjects rather than by forms, particularly from 1995 in Korean universities' libraries. Users especially in university libraries who are frequently seeking information on the specific subject, are going to find a room accoinmodating all forms of information on the subject, that is, one-stop information service. As a result, subject division structure have adopted as a new organizational structure in Korea. Our survey shows 34 out of 73 university libraries in Korea is taking this structure of which collections are arranged by subjects, while the rest of them are operating with a traditional organizational structure by forms focusing on keeping of collection management. In the future, university libraries with traditional organizational structure will be moving towards the subject division structure which is a recommended one by this study.

The horizontal distributions of eggs and larvae of chub mackerel Scomber japonicus were extensively surveyed in the vicinity of Korean waters between 31°75'N and 36°50'N during May and June in 2016 and 2017 (total of four surveys). We used a coupled bio-physical model (DisMELS) that combines an individual-based model (IBM) incorporating vertical migration of larvae and temperature-dependent survival to understand transport processes in the early life stage. Using the distributions of eggs and larvae from surveys, the potential spawning grounds were estimated at the northwest and southeast of Jeju Island and the central East China Sea in May, and at the southwestern East Sea and southern West Sea in June by running the model backward in time. In forward experiments within 30 days from the backward results, most larvae were transported to both the Korean and Japanese sides of the East Sea through the Korea Strait. However, the larvae released in the central East China Sea were transported to the Japanese side only, while those released in the southern West Sea were retained within that region. The survival rates at 30 days after release based on the simulation incorporating temperature-dependent survival throughout May and June were 29.7% in 2016 and 28.8% in 2017.

Hanging scrolls and handscrolls are common mounting for East Asian painting and calligraphy in which wooden Chukmok with Chukdu of various materials are attached either at the top and bottom or at each side of a work. Hanging scroll paintings or calligraphy can be hung for appreciation and rolled up for preservation. The Chukmok and Chukdu of a hanging scroll were made from different materials and were known by distinct names in Korea, China, and Japan. In Korea, the wooden Chukmok were called sanghachukhoengmok(上下軸橫木), which means horizontal wooden bars for the top and bottom axes. The wooden Chukdu were called Chukdu(軸頭), meaning the head of an axis. These Chukmok and Chukdu were made of Korean red pine, nut pine, or shiny xylosma. In China, the rod was called zhougan(軸杆) and zhoutou(軸頭), and they were made of Japanese cedar, sappan wood, or red sandalwood. In Japan, the top rod was called hassou(八双; 八裝) and the bottom jikugi(軸木), and they were made of Japanese cedar, red sandalwood, or crystal. In Korean hanging scrolls, the cross section of a Chukdu is either flat or round, and it can be either patterned or patternless. The designs include concentric circles, two circles, and three circles. Among the portraits of meritorious subjects analyzed in this study, three examples feature concentric circles on Chukdu with a flat cross section, which coincides with most of the king's instructions housed at the Jangseogak Archives. This suggests that flat Chukdu with a concentric circle pattern were used for binding most of the paintings of meritorious subjects commissioned by the royal court.

The mechanical properties and morphologies of cellulose blends with two different additives were compared. Poly (vinyl alcohol) (PVA) of ethylene glycol (EG) were used as additives in the formation of cellulose blends through the solution blending. The properties of blends were varied with the additive content in the polymer matrix. The ultimate tensile strength and initial modulus of the cellulose blends were highest for a blend PVA content of 30 wt% and for a blend EG content of 10 wt%, respectively. Ternary blended systems of composition of cellulose/PVA (70/30=w/w)/EG were also prepared by the solution blending method with different EG contents. The mechanical properties of these systems were found to be optimal for EG contents of up to 40 wt%. The mechanical properties of the cellulose ternary blend films were superior to those of the cellulose binary blend films. The oxygen permeability transmission rate ($O_2TR$) monotonically decreased with increasing EG content in the ternary blend films. Overall, the mechanical properties of the cellulose blend films were found to be better than those of pure cellulose films.
