An unrecorded alien species plant, Phalaris paradoxa L. (Poaceae) was found in Andeok-myeon, Seogwipo-si, Jeju island, Korea. It is native to the Mediterranean region of Europe, and it is currently found worldwide. Phalaris paradoxa is distinguishable from related taxa (P. arundinacea, P. canariensis, P. minor and P. arundinacea var. picta) in Korea by the following combination of characterstics: spikelets in clusters (the upper central fertile spikelet surrounded by six lower sterile spikelets), wing of the keel. This taxon was named 'Nal-gae-ca-na-ri-sae-pul' in Korean based on its character. We provide its description, illustrations, photographs and a key of related taxa in Korea.

Purpose: This study examined the trends in domestic research that applied theory to diabetes patients to suggest future directions of nursing practice and research for diabetes patients. Methods: This scoping review followed the Joanna Briggs Institute guidance. The population was diabetes patients; the concept was a research that applied theory and had no limitations in context. Eligible studies were retrieved from electronic databases of RISS, KMbase, KoreaMed, NDSL, NAL, and nine major domestic nursing journals. Of the 509 retrieved articles, 20 studies met the inclusion criteria. Results: The study included the community (57.1%), and the subjects were mainly type 2 diabetes patients (42.9%). The Information-Motivation-Behavior skills (IMB) model was the most applied theory (36.4%). The theories were primarily from psychology disciplines (72.7%) and predominantly applied as a conceptual framework of the study (55%). Conclusion: The studies that applied theory were conducted mainly in the community. The IMB model was the most applied theory, and the theory was most applied as the conceptual framework. Efforts to close the theory-practice gap and further studies on developing nursing interventions based on theory and verifying their effectiveness are needed to improve nursing practice and study for diabetic patients.

We have experienced 25 cases of aortic aneurysm from October 1987 to January 1996. Patients ranged in age from 26yrs to 73yrs(mean age 52. Syrs). There were 13 males and 12 females. Eighteen cases were thoracic aneurysm and seven were abdom nal aneurysm. The cause of aneurysm were dissecting in 16cases aneurysms and non-dissecting in 9 cases. Risk factors of aortic aneurysm were hypertension, hypercholesterolemia, Marfan's syndrome. In thoracic aneurysm patients, 1'S cases of dissecting aneurysm underwent aneurysmectomy and replacement of vessel interposition graft with or without coronary artery implantation on the graft. 6 cases of non-dissecting aneurysm underwent operation with same policy as dissecting aneurysm. In 7 case of abdominal aneurysm,all patients underwent aneurysmectomy and graft interposition with straight i)r Y graft. Thcre were 5 postoperative death(mortality 20%). Several cases of complications were improved with proper managements. All survivors showed improvement in clinical symptom and sign and discharged without specific complications.

Purpose: The purpose of this study was to analyze literature related to nursing team effectiveness and to summarize the definition variables included, measurement tools, and findings. Basic data on operation and research for team effectiveness in nursing units was sought. Methods: A literature search was performed to identify all studies published between 2003 and 2016 from periodicals indexed in PUBMED, CINAHL, SCIENCE DIRECT, RISS, KISS, and NAL databases. The following keywords were used in the search: 'team effectiveness', 'nurse', 'nursing', and 'hospital'. Ten studies were analyzed. Results: The analysis included domestic and international literature on nursing team effectiveness. The foreign literature included studies of various organizations including nurses, use of various research tools, leadership programs and/or new nursing delivery systems. In the Korean studies, most of the research on team effectiveness surveyed nurses on team satisfaction, team commitment, and team performance in general nursing units, operating rooms, and intensive care units. Conclusion: The findings show the necessity to develop a definition of team effectiveness that can be accepted comprehensively in nursing organizations in Korea. The definition should reflect team effectiveness that includes all cooperating units not only nurses of the nursing unit but also all other related health care teams.

Though the computer has become deeply entrenched as the major tool in information processing(library works), it may be obvious that automatic book classification techniques ate still under experimentation, and the techniques have not yet been tested against the criterion of usefulness. The purpose of this study is to design of knowledge base for automatic book classification which can be put to use in library operation, and to present a methodology of application of the automatic classification into the library. Since the enumerative classification schemes which are existing are manual systems, it cannot be applied to the automatic classification, the principle of faceted classification based on concept analysis is brought in and studied. The result of this study are summarized as follows : 1. The design of knowledge base confined the field of agriculture and medicine. 2. If title is entered by the computer keyboard it will be searched in knowledge base, and then be classified by the principle of automatic classification. 3. Program flowcharts are designed as a bases of classification procedures for automatic subject recognition and classification. 4. 283 books in agriculture, 196 books in medicine were drawn at random from Taegu University Library and Young-Nal Medical Center Library respectively. 5. The experiment of automatic classification is performed 143 books in agriculture 166 books in medicine except for other subject books. 6. It was proved that automatic book classification is possible by design of knowledge base. In addition the expected values from design of knowledge base for automatic book classification are as follows : 1. The prompt and accurate process of classification is possible. 2. Though some title is classified in any library, it can be classified the some classification number by a program. 3. The user can retrieve the classification codes of books for which he or she wants to search through the computer. 4. Since the concept coordination method is employed the representing of a multisubject concept is make simple. 5. By performing automatic book classification the automation of total system can be achieved. 6. The efficient international information transfer will be advanced since all the institution maintain unified classification number.

Objectives : This study was to verify the Attributive Channel theory of herbal medicine. Methods : [$^{131}I$]iodohesperetin was synthesized, separated, and refined from hesperetin, the major component of Citrus species, followed by observing the biodistribution in an organism of C57 BL/6 mice with and without Lewis Lung Carcinoma. Results : Iodohesperetin 27.5 mg was obtained through column cliromatography after a reaction with 50 mg of Hesperitin and 8 mg of Nal. The radiochemical yield of [$^{131}I$]iodohesperetin synthesis was 25 % when checked with Radio TLC chromatography. [131I]iodohesperetin was most largely distributed in the stomach, lung and liver of C57BL/6 mouse. The highest %ID/g in stomach was 40 min, in lung and liver was 20 min after injection. The % ID/g of tumor tissue was comparable with that of blood. Conclusions : The fact that [$^{131}I$]iodocurcumin was most largely distributed in the stomach, lung and liver was related with the Attributive Channel theory. And there was no significant finding related to tumor cells.

Exposure rates due to leakage gamma-rays from operating reactors TRIGA Mark II and III were measured in a horizontal plane by means of scintillation spectrometry using a 3"$\times$3" cylindrical Nal(T1) detector associated with a 400 channel pulse height analyzer under varied conditions of reactor operation. In determining exposure rate due to the leakage gamma-rays at each point of measurement, Moriuchi's spectrum-exposure rate conversion theory was applied instead of using conventional responce matrix method which necessitates very complicated procedures to convert a spectrum into exposure rate. The results show that a basic pattern of "typical" spectrum of the reactor leakage gamma-rays is neither affected by thermal output of the reactor, nor influenced by overall attenuation in radiation intensity. It was indicated that he attenuation of the leakage gamma-rays in air in terms of exposure rate as a whole follows an exponential law, and the total exposure rate due to the leakage gamma-rays at a certain point is nearly proportional to thermal output of the reactor. The complexity in spectrum measured for a movable core reactor, TRIGA Mark III, was analyzed through spectrum resolution, and proper judgement of the leakage gamma-rays in a complex spectrum was discussed.ctrum was discussed.

Rhizobium meliloti populated in five Korean pasture soils were characterized by symbiotic effectiveness and intrinsic antibiotic resistance using whole-soil inoculum and 11 antibiotics, respectively. Most probable number (MPN) of naturalized rhizobia counted with alfalfa Vernal[Medicago sativa (L.)] as a host ranged $1.7{\times}10^2\;cells/g$. soil(Chunghyo, Kyeongiu)-$1.0{\times}10^5\;cells/g$. soil(Gampo, Kyeongiu) and ended to be positively associated with soil pH. On the whole, the effectiveness of population as compared to TAL mix inoculum (TAL 380+TAL 1372+TAL 1373) was very low. Nevertheless, there were two highly effective strains, YCK 539 and YCK 542, which were not inferior to TAL 1372, from Ogpo, Dalseong among the total of 30 of 6 isolates per each soil. As long as mean $N_2$ fixing ability of each soil isolate, the isolates from Hyeongog, Kyeonju were outstanding and the rest were in order of Ogpo, Dalseong>Chunghyo, Kyeongju>Hwaweon, Dalseong>Gampo, Kyeongiu. Isolates as a whole were resistant to erythromycin(67崙), nalidixic acid(77%), and streptomycin sulfate(8051), which had the concentration of $100\;{\mu}g/ml$, $160\;{\mu}g/ml$, and $10\;{\mu}g/ml$, respectively and divided into 14 patterns of resistance. Association between resistances in each soil was not clear. And there was no relationship of resistance pattern to effectiveness. The best effective strain YCKa 542 exclusively fell into No. X pattern having resistance to erythromycin, nalidixic acid, and neomycin sulfate.

Present study aimed to determine the effect of 'bitter melon', a popularly used fruit in Bangladesh and several other Asian countries, on high-fat-diet-induced type 2 diabetes. To investigate the effect, ethanol extract from bitter melon (BME) as a dietary supplement with mouse chow was used. BME was found to significantly attenuate the high-fat diet (HFD) -induced body weight and total fat mass. BME also effectively reduced the insulin resistance induced by the HFD. Furthermore, dietary supplementation of BME was highly effective in increasing insulin sensitivity and reducing hepatic fat and obesity. These results indicate that BME could be effective in attenuating type 2 diabetes and could therefore be a preventive measure against type 2 diabetes.

In reared populations of Allomyrina dichotoma, commercial insects, the skin of last instar larvae was changed softer with opaque white, and infested grubs eventually died. To clarify the cause of the symptom, we collected the larvae of A. dichotoma from five farms and examined their intestinal bacterial florae using pyrosequencing technique. From those results, a member of Paenibacillus was found only in the larvae showing the symptom of disease. Through PCR analysis using a Paenibacillus specific primer set, we obtained the partial 16S rRNA gene sequence and confirmed the microbe as Paenibacillus sp. For clear identification, a whole guts was extracted from each larva showing the sign of the disease and incubated at $70^{\circ}C$ for 15 min to isolate spore forming bacteria. After then, each content of guts was cultured on $MYPGP_{NAL}$ agar medium($12.5{\mu}g/ml$ of nalidixic acid) at $30^{\circ}C$. The 16S rRNA gene sequence analysis for the isolated bacteria showed that they were closely related to P. rigui(97.9% similarity), to P. chinjuensis(96.1% similarity), and to P. soli(95.3% similarity). Additional tests including API test and cellular fatty acid composition analysis were performed, but the strain couldn't be identified at species level, suggesting it may represent novel species of the genus Paenibacillus.
