  • A total of 9,281 larval chigger mites were collected from small mammals captured at Hwaseong-gun, Gyeonggi-do (Province) (2,754 mites from 30 small mammals), Asan city, Chungcheongnam-do (3,358 mites from 48 mammals), and Jangseong-gun, Jeollanam-do (3,169 for 62 mammals) from April-November 2009 in the Republic of Korea (= Korea) and were identified to species. Leptotrombidium pallidum was the predominant species in Hwaseong (95.8%) and Asan (61.2%), while Leptotrombidium scutellare was the predominant species collected from Jangseong (80.1%). Overall, larval chigger mite indices decreased from April (27.3) to June (4.9), then increased in September (95.2) and to a high level in November (169.3). These data suggest that L. pallidum and L. scutellare are the primary vectors of scrub typhus throughout their range in Korea. While other species of larval chigger mites were also collected with some implications in the transmission of Orientia tsutsugamushi, they only accounted for 11.2% of all larval chigger mites collected from small mammals.

  • In this study, we tried to find the moderating effect as an interaction between brand concept variables and thinking style variables as well as the main effect of each. To this end, the inner wear bradns, CalvinKlein(symbolic concepts) and bodyguard(functional concept), as two parent brands and wallets as an extension product were selected. The results of this study were as follows: (i) Extension evaluation as well as fit judgement based on brand concepts was higher in symbolic brand than functional brand. (ii) The holistic thinkers were higher in fit judgement and expansion evaluation than the analytic ones. (iii) In case of symbolic brand, there was little differences in fit judgement and expansion evaluation between holistic thinkers and analytic thinkers. But In functional brand, there was some differences relatively. So, we found the interaction effect between variables in fit judgement and expansion evaluation. We can expect this research result to be helpful in working out diverse and practical marketing strategies using existing brand concepts in the global market environments.

  • This research focuses on functionalism in American fashion designs which have become the center of public attention in recent. First, documentary studies about how functionalism, which originated in Europe in the beginning of the 20th century, has been developed throughout the 20th century were preceded Second, content analysis was done for the articles, including the word ‘unction’,‘utility’ and ‘practical’in the New York Times and American Vogue from January 1990 to January 2001. As a result, functionalism in 1990s has been developed in different ways from the mechanical, organic, and mea analogies of functionalism in the beginning of 20th century. It doesn't belong to an analogy but has the fused characteristics of those three analogies. It can be classified into techno functionalism influenced by new technology, pure functionalism related to minimalism, sports casual functionalism for those who are crazy about the speed and sports and enjoy the freedom and comfort, and symbolic functionalism which stresses Zen style. More casual manners of formal wear are distinct elements in functionalist fashion design in 1990s. It leads to strong expressions of sports casual functionalism, which plays a great role in sportswear industry of American fashion design. The American fashion designers who were mentioned often in the articles were Donna Karan, Calvin Klein, Ralph lauren and Tommy Hilfiger. As well as their works have common formative features based on functionalism, each of them shows his/her own strung color. A]1 of these designers make American fashion design, which can be defined as casual wear or sportswear, very popular worldwide based on the developed American functionalism. Functionalism considering practical and conceptional functions will continue in coming century and techno functionalism and sports casual functionalism in future fashion designs wilt be expressed more strongly with new technology and casual trends of life style.

  • Objectives : There has been substantial evidence that patients with chest pain have depression and anxiety, and show impaired quality of life (QoL). This study aimed to campare the QoL according to types of chest pain and to examine the impact of depression and anxiety on QoL in patients with chest pain. Methods : Forty-seven patients with chest pain were divided into Cardiac-Typical Chest Pain (CTCP, n=22) and Non-Cardiac-Atypical Chest Pain groups (NCACP, n=25) according to the pain characteristics and cardiovascular disease. Patients were assessed for depression using the Beck Depression Inventory (BDI), for anxiety using the State-Trait Anxiety Inventory (STAI), and QoL was assessed using the Korean version of the SmithKlein Beecham 'Quality of Life' Scale (KvSBQOL). Results : Compared with the CTCP group, the NCACP group reported significantly higher anxiety, and lower QoL. There was no significant difference in QoL between the two groups after adjusting for anxiety. The QoL was associated with depression and trait-anxiety in the CTCP group, and with trait-anxiety in the NCACP group. Conclusion : The findings suggest that there are different effects of depression and anxiety on QoL in individuals with CTCP and NCACP. Understanding about these differences can be important in the treatment of patients with chest pain. A large prospective study is needed to confirm these results.

  • This work continues a trend of developments aimed at exploiting the physical layer of the open systems interconnection (OSI) model to enhance wireless network security. The goal is to augment activity occurring across other OSI layers and provide improved safeguards against unauthorized access. Relative to intrusion detection and anti-spoofing, this paper provides details for a proof-of-concept investigation involving "air monitor" applications where physical equipment constraints are not overly restrictive. In this case, RF fingerprinting is emerging as a viable security measure for providing device-specific identification (manufacturer, model, and/or serial number). RF fingerprint features can be extracted from various regions of collected bursts, the detection of which has been extensively researched. Given reliable burst detection, the near-term challenge is to find robust fingerprint features to improve device distinguishability. This is addressed here using wavelet domain (WD) RF fingerprinting based on dual-tree complex wavelet transform (DT-$\mathbb{C}WT$) features extracted from the non-transient preamble response of OFDM-based 802.11a signals. Intra-manufacturer classification performance is evaluated using four like-model Cisco devices with dissimilar serial numbers. WD fingerprinting effectiveness is demonstrated using Fisher-based multiple discriminant analysis (MDA) with maximum likelihood (ML) classification. The effects of varying channel SNR, burst detection error and dissimilar SNRs for MDA/ML training and classification are considered. Relative to time domain (TD) RF fingerprinting, WD fingerprinting with DT-$\mathbb{C}WT$ features emerged as the superior alternative for all scenarios at SNRs below 20 dB while achieving performance gains of up to 8 dB at 80% classification accuracy.

  • Black light traps were used to measure the seasonal and geographical distribution of Culicoides spp. (biting midges or no-see-ums) at 9 cowsheds in the southern half of the Republic of Korea (ROK) from June through October 2010. A total of 25,242 Culicoides females (24,852; 98.5%) and males (390; 1.5%) comprising of 9 species were collected. The most commonly collected species was Culicoides punctatus (73.0%) followed by C. arakawae (25.7%), while the remaining 7 species accounted for <1.0% of all Culicoides spp. collected. The mean number of Culicoides spp. collected per trap night (Trap Index [TI]) was highest for C. punctatus (409.3), followed by C. arakawae (144.2), C. tainanus (4.1), C. oxystoma (1.2), C. circumscriptus (0.7), C. homotomus (0.6), C. erairai (0.4), C. kibunensis (0.3), and C. nipponensis (0.04). Peak TIs were observed for C. punctatus (1,188.7) and C. arakawae (539.0) during July and August, respectively. C. punctatus and C. arakawae have been implicated in the transmission of arboviruses and other pathogens of veterinar importance that adversely impact on animal and bird husbandry.

  • A survey to determine the geographical distribution and relative abundance of potential vectors of scrub typhus was conducted from October to November 2006 at 13 localities throughout the Republic of Korea. Apodemus agrarius accounted for 97.6% (80/82) of all rodents, while only 2 Myodes regulus (2/82) were collected. A total of 10,860 chiggers were collected from A. agrarius belonging to 4 genera and 8 species, while only Walehia fragilis (40) was collected from Myodes regulus. Leptotrombidium pallidum (8,137; 74.9%), a vector of scrub typhus, was the predominant species collected from A. agrarius followed by Leptotrombidium scutellare (2,057, 18.9%), Leptotrombidium palpale (279; 2.7%), Leptotrombidium orientale (232; 2.1%), and Leptotrombidium zetum (79; 0.7%), Neotrombicula tamiyai (58; 0.5%), Euschoengastica koreaensis (16; 0.1%), and Cheladonta ikaoensis (2; < 0.1 %). L. pallidum was the predominant chigger collected at collection sites in Gangwon (100%), Gyeonggi (87.2%), Chungnam (100%), Chungbuk (100%), Jeonbuk (73.9%), Jeonnam (77.0%), and Gyeongbuk (66.1%) provinces, whereas L. scutellare was the predominant chigger collected in Gyeongnam province (77.9%) and Jeju Island (62.3%). Data suggest a correlation between chigger population abundance and human cases of scrub typhus in Korea.

  • Biting midges (Culicoides: Ceratopogonidae) were collected by Mosquito Magnet$^{(R)}$ traps at the Neutral Nations Supervisory Commission (NNSC) camp and Daeseongdong village inside the demilitarized zone (DMZ) and near the military demarcation line (MDL) separating North and South Korea and at Warrior Base (US Army training site) and Tongilchon 3 km south of the DMZ in northern Gyeonggi Province, Republic of Korea (ROK), from May-October 2010-2012, to determine their seasonal distributions. A total of 18,647 Culicoides females (18,399; 98.7%) and males (248; 1.3%) comprising 16 species were collected. Overall, the most commonly collected species was Culicoides nipponensis (42.9%), followed by C. erairai (29.2%), C. punctatus (20.3%), C. arakawae (3.3%), C. pallidulus (1.8%), and C. circumscriptus (1.4%), while the remaining 10 species accounted for only 1.1% of all Culicoides spp. collected. The seasonal distribution of C. nipponensis was bimodal, with high numbers collected during May-June and again during September. C. erairai was more frequently collected during June-July, followed by sharply decreased populations from August-October. C. punctatus was collected in low numbers from May-September with high numbers collected during October. C. erairai was predominantly collected from the NNSC camp (85.1% of all C. erairai collected) located adjacent to the MDL at Panmunjeom in the northernmost part of Gyeonggi-do (Province), while other sites yielded low numbers of specimens.

  • This study describes the seasonal distribution of larvae, nymph, and adult life stages for 3 species of ixodid ticks collected by tick drag and sweep methods from various habitats in the Republic of Korea (ROK). Grasses less than 0.5 m in height, including herbaceous and crawling vegetation, and deciduous, conifer, and mixed forests with abundant leaf/needle litter were surveyed at United States (US) and ROK operated military training sites and privately owned lands near the demilitarized zone from April-October, 2004 and 2005. Haemaphysalis longicornis Neumann adults and nymphs were more frequently collected from April-August, while those of Haemaphysalis flava Neumann and Ixodes nipponensis Kitaoka and Saito were collected more frequently from April-July and again during October. H. longicornis was the most frequently collected tick in grass habitats (98.9%), while H. flava was more frequently collected in deciduous (60.2%) and conifer (57.4%) forest habitats. While more H. flava (54.1%) were collected in mixed forest habitats than H. longicornis (35.2%), the differences were not significant. I. nipponensis was more frequently collected from conifer (mean 8.8) compared to deciduous (3.2) and mixed (2.4) forests.
