Simultaneous time monitoring observations of H2O 616 − 523, SiO J = 1–0, 2–1, 3–2, and 29SiO v = 0, J = 1–0 lines are carried out in the direction of the Mira variable star TX Cam with the Korean VLBI Network single dish radio telescopes. For the first time, the H2O maser emission from TX Cam is detected near the stellar velocity at five epochs from April 10, 2013 (Ø = 3.13) to June 4, 2014 (Ø = 3.89) including minimum optical phases. The intensities of H2O masers are very weak compared to SiO masers. The variation of peak antenna temperature ratios among SiO v = 1, J = 1–0, J = 2–1, and J = 3–2 masers is investigated according to their phases. The shift of peak velocities of H2O and SiO masers with respect to the stellar velocity is also investigated according to observed optical phases. The H2O maser emission occurs around the stellar velocity during our monitoring interval. On the other hand, the peak velocities of SiO masers show a spread compared to the stellar velocity. The peak velocities of SiO J = 2–1, and J = 3–2 masers show a smaller spread with respect to the stellar velocity than those of SiO J = 1–0 masers. These simultaneous observations of multi-frequencies will provide a good constraint for maser pumping models and a good probe for investigating the stellar atmosphere and envelope according to their different excitation conditions.

The average prevalence rate (PR) for foodborne disease outbreaks (FBDOs) in the first half (F-H) and latter half (L-H) of the decade from 2001 to 2010 in Korea was 14.0 and 16.9 per 100,000 population, respectively. The number of patients per outbreak of foodborne diseases (FBDs) in the F-H of that decade was 57.6 and in the L-H was 25.4 (p < 0.05). A comparison of the 2 periods covered in this study indicates that FBDOs in the L-H most frequently involved restaurants or delis (51.5% of total cases), and in the F-H, this involvement was noted in 34.0% of total cases (p < 0.01). The epidemic patterns of microbial FBDOs show that the overall incidence of outbreaks resulting from 5 of 8 key pathogens including Bacillus cereus (+1.6%), Campylobacter jejuni (+1.5%), Clostridium spp. (+0.7%), pathogenic Escherichia coli (+8.3%), and Norovirus (+14.4%) tended to be higher in the L-H than in the F-H of the decade from 2001 to 2010. Conversely, those caused by the other 3 key agents, including Salmonella spp. ( 9.2%), Staphylococcus aureus ( 2.8%), and Vibrio parahaemolyticus ( 6.4%) were significantly lower in the L-H than in the F-H of the decade. Moreover, in the decade between 2001 and 2010, the number of patients (n) and the PR for microbial FBD increased from the F-H (n = 13,346, PR: 5.6) to the L-H (n = 33,732, PR: 13.8) (p < 0.01).

Presently, the first pregnancy age of dairy heifers attended National Dairy Herd Improvement Program (NDHI) in Korea has increased, and more research have been requested to evaluate the possibility of decreasing the first pregnancy age of dairy heifers. Accordingly, this study was investigated the effects of the month of age at the first service and pregnancy on the reproductive efficiency of Holstein heifers. For these, the reproductive performance of heifers was analyzed by evaluating the effects of first insemination service at 12-14 months of age (12 month old), 15-16 months of age (15 month old), 17-19 months of age (17 month old), and > 20 months of age (20 month old) in Holstein heifers. The service numbers per conception in the first insemination months were 1.85±1.22, 1.59±0.77, 1.58±0.72, and 1.76±0.97 times at 12, 15, 17 and 20 months of age, respectively. The conception rates in the first service were 51.2, 57.8, 54.8, and 52.9% at 12, 15, 17 and 20 months of age, respectively. The conception ages were 453.2±78.9, 512.1±75.9, 590.1±98.0, and 713.0±74.5 days in the heifers serviced firstly at 12, 15, 17 and 20 months of age, respectively. There was significantly difference in the conception age among groups (p<0.05). The cumulative conception rates in the heifers serviced firstly at 12, 15, 17 and 20 months of age were 51.21, 57.8, 54.8 and 53.0% by the first service, 29.8, 30.1, 32.3, 23.5% by the second service, and 19.0, 12.1, 12.9 and 23.5% by the third service, respectively. The service numbers per conception in the first pregnancy months were 1.31, 1.55, 2.0, 2.05 times at 12, 15, 17 and 20 months of the first service age, respectively. The service numbers per conception in the 12 and 15 months of age were significantly lower than those in the 17 and 20 months of age (p<0.05). The rates of repeat-breeder were 6.0, 11.3, 22.0, and 41.0% in the heifers serviced firstly at 12, 15, 17 and 20 months of age, respectively. These results demonstrate that first pregnancy of Holstein heifers should be conducted at 15 months of age, because the age at first pregnancy in heifers can be substantially influenced through implementation of reproductive management and performance.

The movement, survival, and weight gain of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) first instar larvae were studied on CB9, CB10 and SR05 cotton varieties under field conditions. The neonate H. armigera were released on the cotton varieties at the squaring stage of the plants and, after a period of 72 hours, the survival, weight gain, and final location of the larvae were observed. While the different cotton varieties had no effect on the survival and weight gain of the larvae, the release locations on the cotton varieties had a significant influence on the larval survival and weight gain. The larvae fed small squares of the cotton varieties were significantly heavier and showed a higher mortality than the larvae fed leaflets and mature leaves. For the cotton varieties in this study, the larvae released on leaflets showed a significantly higher rate of recovery compared to the larvae released on mature leaves and squares. This study also found that that the larvae on leaflets did not move up or downward unlike the larvae on mature leaves and squares. This information on the foraging behavior of larvae on cotton varieties will assist researchers to interpret field data and thereby help with the development of pest management decisions.

In this study, we report for the first time a hybridization between Caretta caretta and Chelonia mydas in South Korea. On 7th May 2012, a sea turtle (Jeju sea turtle 01, JST01) was found in the east coast of Jeju Island, South Korea. The morphological characteristics of JST01 were compared with those of C. caretta and C. mydas that were frequently observed in Korean Seas. Interestingly, JST01 showed similar morphological characters such as body color, appearance of carapace, shape of upper beak, serration on marginal scute, and two claws with those of C. caretta. On the other hand, JST01 showed also similar patterns in several characteristics including the numbers of marginal, inframarginal and costal scute, smooth carapace without keel, no contact between costal scute and nuchal scute with those of C. mydas. From these results, we suggest that JST01 is one of hybrid animals bred between C. caretta and C. mydas, because JST01 has speciesspecific characters from both species. We anticipate that our study would be useful and have significant impact onto study inter-specific hybridization in the groups of sea turtle.

In the past two decades, European ash trees (Fraxinus spp.) have been severely damaged by ash dieback disease of which causal agent is a fungal species called Hymenoscyphus fraxineus (anamorphic stage Chalara fraxinea). Recent molecular phylogenetic and population genetic studies suggested that this fungus may have been introduced from Eastern Asia to Europe. In the course of fungal biodiversity survey in Korea, H. fraxineus-like apothecia were collected from fallen leaves, rachis and petioles of Korean ash and Manchurian ash trees. The morphological and ecological traits of these materials are provided, supplemented by ITS rDNA sequence comparison of H. fraxineus strains collected from Europe, China and Japan.

The three important turns in philosophy in the twentieth century: linguistic (Wittgenstein), hermeneutical (Heidegger, Gadamer) and cognitive (Fodor, Churchland, Dennett).The interrelation among the above three turns and the significance of cognitive turn in philosophy is discussed in recent debates both in Indian and Western philosophical traditions. Thus consciousness reemerged as one of the problems of scientific (A.K. Mukhopadhyay, B.V. Sreekantan, Rajesh Kasturirangan) as well as philosophical community (R. Balasubramanian, Bina Gupta). Four types of responses to consciousness: D-I-M-E (Deflation, Irreducibility, Magic and Eliminativism).

Recently in the course of examining Korean diptera, we found a species, Atrichopogon femoralis Tokunaga placed in the subfamily Forcipomyinae Meigen. Forcipomyinae is most specious in the family Ceratogonidae, and comprise about 5,566 extant species placed in 103 genera in four subfamilies (Borkent and Wirth, 1997) from almost all the zoogeographic regions. Genus Atrichopogon is second largest genus, with about 520 species (Borkent, 2012). Currently 39 valid species of 6 genera belonging to 3 subfamily are known in Korea. The specimens were collected from intermountain area and reservoir of Chungcheongnam-do, Cheonan-si, and Gyeongsangbuk-do, Gyeongju-si by black light trap (BLT) in 2013. We report an occurrence Atrichopogon femoralis Tokunaga for the first time in Korea, and of which diagnosis, description, distribution and photo images are presented. For further researches, we also provide a key to genera of Korean Ceratopogonidae.

The Ceratovacuna aphids are one of the major gall-forming aphids. Four Ceratovacuna aphids have been reported from East Asia including Taiwan, Korea, and Japan. In Korea, only one species, Ceratovacuna nekoashi (Sasaki), has been confirmed amongst the four species, and yet their colonies have been found only from the banana bundle or cats-paw shaped galls on the primary hosts, Styrax trees (Styraceae). Colonies on the secondary hosts (Gramineae) have not been seen from Korea nor confirmed from Taiwan, although they are usually seen from Japan limitedly on stiltgrass Microstegium vimineum. Recently in Korea, a colony consisting of an emigrant and first instar soldiers were found from a grass species, Seteria sp. that have not been reported as a secondary host of C. nekoashi. Identity of C. nekoashi is definite based on morphology of the first instar soldier. Genetic identity is being explored for confirmation.

The oedemerid species Oedemera sexualis Marseul, 1877 is reported for the first time from Korea. The genus Oedemera Olivier, 1789, within subfamily Oedemerinae and family Oedemeridae, is one of the common oedemerid beetles being widely distributed throughout the world. The world-widespread genus Oedemera is presented 3 subgenera and 104 species in Palaearctic region. Until now, 8 species and subspecies were recorded in Korea. O. sexualis was found in Is. Yongcho and Is. Bijin in Tongyeong-si, Gyeongsangnamdo of Korea, bringing the number of Korean Oedemera species to 9 species. In this study, we report the taxonomic key to the genus Oedemera of Korea, and morphological description of O. sexualis.

Subjective knowledge (SK thereafter) is defined as what consumers think they know, or their perceived level of knowledge (Brucks, 1985). SK influences what consumers search for, the effort that they put into searching, and the purchasing decision and choice of brands they finally make (Hadar, Sood, & Fox, 2013; Moorman, Diehl, Brinberg, & Kidwell, 2004). The existing literature on consumer knowledge development mainly argues that SK development is associated with consumers’ product related experience, such as product ownership and experience from usage (Alba & Hutchinson, 2000; Park, Mothersbaugh, & Feick, 1994). This study contributes to the literature as follows. We consider a broad market segmentation where the market consists of product owners and non-owners, The literature suggests that these two groups of consumers should have different levels of perceived knowledge due to their different product-specific experience (Park et al., 1994). Our research specifically contends that it is important to distinguish, within the group of non-owners, between those who intend to buy and those who do not intend to buy the product. Thus, this study examines how previous ownership and intention to buy, which is the goal motivation, influence the SK levels of consumers, which in turn impacts on consumers’ heterogeneous preferences for different attributes within a product category. It is contended that the motivation to learn about a product category of non-car owners who have strong intentions to buy influences what this group learns compared to those non-owners who do not intend to buy. More specifically, the research proposes to uncover how learning influences how different groups of consumers perceive their subjective knowledge and how this relationship in turn shapes their preferences, especially when we compare owners and non-owners who have strong intentions of buying a product. Therefore, we develop following research hypotheses: H1: The SK level is positively associated with the product ownership experience. H2: The SK level is positively associated with purchase intention. H3: The relationship between purchase intention and SK level is moderated by the ownership of the product. H4: Preference heterogeneity for different types of brand attributes of the product between owners and non-owners is moderated by the SK level. The empirical context that illustrates the importance of this research is the Chinese car market where the majority of consumers are first time buyers. Our research shows that the SK level is positively associated with both car ownership and purchase intention. Furthermore, the segmentation analysis finds that purchase intention has a significant effect only on non-car owners’ SK level, while the effect on car owners’ SK level is insignificant. An interesting finding is that SK development, in turn, influences consumer’s preferences for different types of brand attributes of a product. We demonstrate the role of SK in forming consumer preference heterogeneity by comparing preferences for a tangible and a non-tangible brand attribute respectively across different consumer segments. We further show how this preference heterogeneity across two consumer segments (car owners versus non-car owners) depends on their SK level. The results of this study can be generalized beyond the specific context of the empirical study of the Chinese car market when marketers are considering new products launch or launching products where the majority of consumers may be unfamiliar with the product.

Aluminum nitride(AlN) films were grown on the C-face and on the Si-face of (0001) silicon carbide(SiC) substrates using plasma-assisted molecular-beam epitaxy(PA-MBE). This study was focused on first-stage growth manipulation prior to the start of AlN growth. Al pre-exposure, N-plasma pre-exposure, and simultaneous exposure(Al and N-plasma) procedures were used in the investigation. In addition, substrate polarity and, first-stage growth manipulation strongly affected the growth and properties of the AlN films. Al pre-exposure on the C-face and on the Si-face of SiC substrates prior to initiation of the AlN growth resulted in the formation of hexagonal hillocks on the surface. However, crack formation was observed on the C-face of SiC substrates without Al pre-exposure. X-ray rocking-curve measurements revealed that the AlN epilayers grown on the Si-face of the SiC showed relatively lower tilt and twist mosaic than did the epilayers grown on the C-face of the SiC. The results from the investigations reported in this paper indicate that the growth conditions on the Si-face of the SiC without Al pre-exposure was highly preferred to obtain the overall high-quality AlN epilayers formed using PA-MBE.

Members of the order Psocoptera are known as psocids (commonly called booklice or bark lice). There are more than 5,500 species in 41 familes in three suborders. The suborder Psocomorpha is the largest suborder in Psocoptera, containing 25 of the 41 psocopteran families. Psocomorphan familes are classified into four groups: Epipsocetae, Caeciliusetae, Homilopsocidea and Psocetae. Families Caeciliusidae and Stenopsocidae belong to the group Caeciliusetae. The family Caeciliusidae is the largest family of Psocomorpha, and is widely distributed in all zoogeographical regions. Monophyly was not supported by any autapomorphy (Yoshizawa, 2002). The Stenopsocidae is distributed in the Afrotropical, Palearctic, Oriental, and Australian regions. Monophyly is well supported by the presence of the R1-R2+3 crossvein, M-CuA1 crossvein, and lateral pouch of the spermathecal sac (Yoshizawa, 2002). These families, Caeciliusidae and Stenopsocidae consist of about 676 described species in 32 genera and about 188 described species in 4 genera, respectively. In Asia, there were reported 337 species belonging to 11 genera and 154 species belonging to 4 genera from China (Li, 2000) and 22 species belonging to 6 genera and 7 species belonging to 2 genera from Japan (Yoshizawa, 2004), respectively, but there have not been known from Korea until now. This study is the first work to make the checklist of the Korean Psocoptera. Through this study, I have reported 2 species of families Caeciliusidae and Stenopsocidae new to Korea, respectively. Family Caeciliusidae Valenzuela oyamai (Enderlein, 1906) Paracaecilius japonicus (Enderlein, 1906) Family Stenopsocidae Cubipilis aphidiformis (Enderlein, 1906) Stenopsocus immaculatus (Stephens, 1836)

Generally, Cerambycidae inhabites in tropical and subtropical zones, and they are large family among Coleoptera and distributed over 20,000 species worldwide. They typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. Order Cerambycidae are divided into 11 subfamilies in the world, among them, there are 304 species of the 159 genera in 7 subfamilies from Korea up to date. The genus Anoplophora is belonging to the tribe Agniini in the subfamily Lamiinae. Most species of Anoplophora are showed their beautiful colors on the elytra, pronotum, antennae and ventral parts etc. These colors superficially seems like mere patterns of the integument. Usually, colored pubescent patches of the elytra in Anoplophora are arranged in round spots, in others they are arranged in transverse bands. And also, the species of this genus have very long antennae (about 1.3-1.6 times the body length in males, 1.0-1.5 times the body length in females of most species) then others and mostly body size are large, some species is over 50mm. In this paper Anoplophora freyi is newly recorded in Korea. Consequently, a total of three species of the genus Anoplophora are recorded in Korea.
