Records found on labels of specimens deposited at Kyoto University (KYO) and references about three Japanese taxonomists, Koidzumi, Gen'ichi (1883-1953), Ohwi, Jisaburo (1905-1977), Kitamura, Siro (1906-2002) were assembled to produce collector's itineraries from 1930 to 1935 in Korea. The quality of data on labels of the specimens varies, but most are only the collector's name and country of collection, often, the locality data are only textual, and the Chinese and Japanese names, as well as the ethnic dialects common to the region, varies widely. It is estimated that approximately 2,000 specimens collected from Korea by three taxonomists are currently held within the collections of Kyoto University herbarium (KYO). Koidzumi, who was the professor of Kyoto University, traversed different northern parts of the country, such as Island Jeju-do, Mt. Keumkang-san, Hamkyongbuk-do during summer (July to August) in 1932, 1933, and 1935. In 1930 and 1932, Ohwi spend three months in the unexplored mountains in northern parts, such as Hamkyeongnam-do, Hamkyeongbuk-do, and Gangwon-do. On the other hand, for two months in the middle of 1935 visited Jeju-do, Mt. Jirisan and travelled through southern parts. Unlike two previous botanists, major collections in Korea by Kitamura took place twice in one major area in northern part and Jeju-do and Mt. Keumgang-san in 1930, 1932, and 1935.

A total of 32 human diphyllobothriasis cases have been reported so far in Korea, exclud- ing 21 egg-positive cases from stool examinations. Authors experienced five more human cases of DiphHllobothrium latum infection, especially infected due to eating raw flesh of redlip mullet, Lizc hoematocheiln. Five cases were neighbors residing in the Puchon area, Kyonggi-do, who ate raw mullets (L. hQematocheila) in a party in February 1996. The mul- lets were purchased at the Noryangjin fisheries market in Seoul. All of cases (2 males and 3 females) were 35 to 43 years old and healthy with the body weight range of 56-62 kg. They complained about gastrointestinal trouble and abdominal discomfort, but were in normal ranges of their hematology and urinalysis data. None revealed any sign of anemia The patients experienced natural discharge of a chain of segments before, and showed diphyllobothriid eggs in their stool specimens when they visited our laboratory. They were administered with praziquantel (15 mg/kg of body weight) and 30 g of magnesium sulfate as a purgative. Two whole worms with the scolices (310-340 cm in length; 8-13 mm in width) were expelled each from two out of five cases after anthelmintic treatment, and the others expelled the parts of strobilae without scolex. The worms were identified as D. Ictum, based on the following biological characters. external morphologies, coiling of uterus, the number of uterine loops, position of genital opening, morphologies of cirrus, cirrus sac and seminal vesicle on the histological sections, position of vagina and uterine pore , and microscopical and SEM morphologies of the eggs.

The objective of this paper is to investigate both the processes of regional policy and their determinants of the International Garden Exposition Suncheon Bay Korea 2013(IGEXPO 2013). IGEXPO 2013 was held in Suncheon from April to October 2013, and almost 440 million tourists visited to IGEXPO 2013. The processes of regional policy of the IGEXPO initiative were divided into four stages; the first stage from 1992 to 2002 was a beginning of conservation movement for Suncheon Bay; the second stage from 2003 to 2007 was a constructing of natural ecological park of Suncheon Bay; the third stage from 2008 to 2010 was a beginning of IGEXPO initiative and a confirming of the IGEXPO 2013; the four stage from 2011 to 2013 was a preparing and holding of IGEXPO 2013. The major determinants related to regional policy development process of IGEXPO initiative are the population n movement for Suncheon Bay, the rergional development strategy for central city in Gwangyang Bay area, the leadership for continuity of regional policy oriented to environmental and ecological city, and the cooperation and competition relationalship with neighboring city, in particular Yeosu city and 2012Yeosu EXPO planning. IGEXPO 2013 has been evaluated as having some performances such as the enhancement of city image, establishment of city park as a public goods, and formation of community leadership promoting continuous urban policy for environmental & ecological city.

This study analyzed visitors' behaviors in the viewpoint of Attraction Power and Holding Power of exhibits on the basis of exhibition layout of real science museums. Through the analysis, the study grasped efficiency of analysis index and exhibition environment elements which might have an effect on planning the exhibition space of a large-scale museum and producing detailed ranges of exhibition. The main indicators used are: 1. Attraction Power: it indicates the relative incidence of people who have stopped in front of an object/exhibit during the exhibition tour. It is calculated by dividing the number of people who stop by the total number of people who have visited the museum or gallery. 2. Holding Power: it measures the average time spent in front of an information/communication element. It is calculated by dividing the average time of stay by the time "necessary" to read an element. As a result of analyzing the exhibition areas of National Science Museum (Daejeon) and National Museum of Emerging Science and Innovation(Tokyo), the Holding Power was found to be relatively lower than the Attracting Power. This means that 3.5 out of 10 visitors stop in front of the exhibit in 6 exhibition areas, and among these, only 1/10 is used when compared to the user required time of the exhibits. In other words, like the method of deriving an analysis index, the stage of viewing can be categorized as Attracting Power and Holding Power, and because the stage from Attracting Power to the stage of Holding Power are strongly linked, it shows that it is not easy to display a meaningful result. Except, the general distribution of Attracting Power was shown to be high from the entrance area of the exhibition hall based on the standard of viewing sequence. Also, the Holding Power became sequentially lower according to the sequence of exhibition viewing and displayed a meaningful interrelationship with the distribution ratio of island exhibits. In the case of island exhibition method, it is less influenced by the movement flow of visitors when compared to the wall type method of exhibition and can be understood as an exhibition method that provides spatial chances enabling stopping and viewing.

In this study, an empirical analysis was performed with regards to traditional markets in Seoul, South Korea to find which physical maintenance elements, such as facility improvement for successful urban restoration, have greater effects on the expectation and activation awareness of successful urban restoration. This study targeted traditional markets located at the center of Seoul, which are visited by many domestic and international tourists as well as general consumers and are revitalizing the downtown area. A survey was conducted to collect a total of 515 completed questionnaires. Data analysis was performed using SPSS 23.0 and AMOS 22.0. The results of the analyses in this study indicate relevant urban invigoration factors (psychological, physical, diversity, functional, and stability factors), and it was observed that the expectation of urban regeneration was under the direct influence of the invigoration factors. Such a finding is meaningful in that it suggests a set of criteria to evaluate the concept of traditional markets in a comprehensive manner for successful urban regeneration while highlighting relevant invigoration factors for traditional marketplaces for the purpose of urban regeneration.

The purpose of this study is to improve the reemployment rate of unemployed job seekers aged 50 to 59 by supporting the foundation of our society and enhancing their value of life. We analyzed the impact of resilience, a psychological factor, on job seeking of unemployed people in their fifties. Subjects were visited and provided employment services in the Employment Welfare Plus Center in the Seoul Metropolitan Area. We devised a questionnaire consisting of three variables of general characteristics, resilience, and job search. Also, the resilience variables comprised sub-variables of control, positiveness, and sociality, and the job search variables involved sub-variables of job preparation, attitude, and willness. Study results the resilience of unemployed persons aged 50 to 59 is above average, and sub-variables of positiveness are highest compared to other sub-variables. Second, there is no significant gender difference in resilience for job search activities. Third, resilience and its sub-variables, such as control and affirmation, affect job-seeking activities. Therefore, this study suggests strengthening the resilience of job seekers in their fifties as well as providing psychological counseling and job training for job-seeking activities.

Purpose: To study the usefulness of the procalcitonin (PCT) test in young febrile infants between 1 and 3 months of age. Methods: We evaluated the medical records of 336 febrile infants between 1 and 3 months of age who visited the Emergency Department or outpatient department of Samsung Changwon Hospital from May 2015 to February 2017, and analyzed the clinical characteristics between infants in the serious bacterial infection (SBI) group and non-SBI group. Results: Among the 336 infants, 38 (11.3%) had definitive SBI (bacteremia, n=3; meningitis, n=1; urinary tract infection, n=34). The mean PCT ($6.4{\pm}11.9ng/mL$) and C-reactive protein (CRP) level ($3.8{\pm}2.6mg/dL$), and the absolute neutrophil count (ANC) ($6,984{\pm}4,675$) for patients in the SBI group were significantly higher than those for patients in the non-SBI group (PCT, $0.3{\pm}1.2ng/mL$; CRP, $1.3{\pm}1.6mg/dL$; ANC, $4,888{\pm}3,661$). PCT had lower sensitivity (43.6%), but higher specificity (92.6%) and accuracy (86.9%) than CRP (92.3%, 25.3%, and 33.0%) for identifying SBI. The area under the receiver operating characteristic curves (AUCs) for definitive SBI were PCT 77.0%, CRP 80.8%, WBC 56.8%, ANC 67.8%, and PLT 48.1%. The AUCs for definitive SBI were PCT+CRP 85.4%, PCT+WBC 77.2%, PCT+ANC 81.3%, CRP+WBC 80.1%, and CRP+ANC 81.6%. Conclusion: Our results suggest that the PCT test or a combination of PCT and CRP tests is a more accurate and specific biomarker to detect and rule out SBIs.

Purpose: In patients with traumatic hemoperitoneum or pelvic bone fracture who underwent angiography and embolization, we want to find the prognostic factors related with mortality. Methods: Patients(333 patients) who visited our hospital with traumatic injury from March 2008 to April 2012 were included in this study. Only 37 patients with traumatic hemoperitoneum or pelvic bone fracture underwent angiography and embolization. A retrospective review was conducted, and Glasgow coma scale (GCS), Revised trauma score (RTS), Injury severity score (ISS), initial laboratory finding and time interval, the amount of transfusion from the arrival at the ER to the start of embolization, and the vital signs before and after procedure were checked. Stastical analysis was conducted using the Chi square and Mann-Whitney U test. Results: In univariate analysis, the amount of transfusion, the base deficit before procedure, the systolic blood pressure before and after the procedure, the GCS, the RTS and the ISS were significantly associated with prognosis. In the multivariate analysis, the ISS and the base deficit had significant association with prognosis. Of the 37 patients who underwent angiography and embolization, 31 patients needed not additional procedure (Group A) while the other 6 patients needed an additional procedure (Group B). After procedure, a statistically significant higher blood pressure was observed in Group A than in Group B. As to the difference in blood pressure before and after the procedure, a statistically significant decrease in systolic blood pressure was observed in Group B, but an increase was observed in Group A. Conclusion: In traumatic hemoperitoneum or pelvic bone fracture patients who underwent angiography and embolization, GCS, ISS, RTS, transfusion amount before the procedure, initial base deficit and systolic blood pressure were factors related to mortality. When patients who underwent angiography and embolization only were compared with patients who underwent re-embolization or additional procedure after the first embolization, an increase in systolic blood pressure after embolization was a prognostic factor for successful control of bleeding.

Purpose: Pertussis can be prevented with a vaccine. Despite this, there have been an increasing number of cases worldwide, and also in Korea. This study aimed to investigate the epidemiology and clinical characteristics of the recent outbreak in the Changwon area. Methods: Patients who visited Changwon Fatima Hospital from July 2015 to March 2016 with respiratory symptoms, including spasmodic cough, cough induced vomiting, inspiratory 'intake' sound (whooping), and a night-time cough for >1 week were included in this study. Respiratory specimens were collected from patients and a polymerase chain reaction (PCR) and detected anti-pertussis immunoglobulin G enzyme-linked immunosorbent assay kit test were performed. Patients with underlying diseases, or those who had received a DTaP or Tdap vaccination in recent 1 year were excluded. Results: Pertussis was diagnosed in 37 of 50 patients, two patients were positive according to the PCR, and 37 patients were positive according to serologic tests. The age distribution of the patients was 1 month to 15 years. After administering antibiotics, all patients recovered without complications. Conclusions: A pertussis outbreak occurred in Changwon in 2015 and 2016. This data can provide the basis for further study on the epidemiology of pertussis in Korea.
