The present study attempted to compare the behavioral patterns and attitudes of American and Korean female students toward apparel ads in magazines in relation to their physical self-concept. The study used a self-administered questionnaire. The sample consisted of 730 female students majoring in the fields related to clothing and textiles : 310 American students at six colleges and universities located in the west, northeast and southwest parts of the U.S., and 412 Korean students at four Seoul-based universities. Likert scales were used for most measures with 1=never or very unimportant and 5 =always or very important. Physical self-concept was measured on the basis of W. S. Jung's Standardized Self-concept Test and Tennessee Self-concept Scale. Surreys were back translated for validity. Percentage, t-test, Contingency Tables and Chi-square were used for the analysis of the data. Results are as follows : (1) Korean students read more magazines than U.S. students, however, Vogue was the most popular for both groups. (2) Those with a high sense of Physical self-concept read more magazines. for both countries. (3) American students'attitudes toward apparel ads in magazines were similar, regardless of whether their sense of physical self-concept was high or low. For Koreans, those with higher sense of physical self-concept showed greater interest in magazine ads, consulted magazines for fashion trends, found ads more useful, and more often expressed satisfaction with the ads, than the lower self-concept group. (4) Korean students cited a lack of information in ads while American students felt body types of models were unrealistic. Both Koreans and Americans in the higher self-concept group expressed a greater level of dissatisfaction with apparel ads in magazines. (5) Advertisers should attempt to again a deeper understanding of the socio-psychological characteristics of their readership as self-concept appears to be related to several magazine readership attitudes and behaviors. Magazines targeting Americans might consider the importance of coordination and merchandising. Apparel ads targeting Korean should consider the importance of company ads.

An efficient method of shoot regeneration of peanut is described. In vitro shoot organogenesis from the callus of cotyledon explants of Arachis hypogaea L. was stimulated by addition of Adenine sulphate (Ads) along with 6 - benzylaminopurine (BAP) and - napthalene acetic acid (NAA). Ads (13 ${\mu}{\textrm}{m}$) had a stimulatory effect on shoot bud differentiation when combined with BAP (13 ${\mu}{\textrm}{m}$) and NAA (2 ${\mu}{\textrm}{m}$). Shoot organogenesis was markedly higher (92%) from callus induced on Ads, BAP and NAA combined media than from those formed by the individual supplementation of Ads or BAP with NAA. The shoots elongated on the media with GA$_3$ (1 ${\mu}{\textrm}{m}$). Elongated plantlets rooted with MS media containing IBA (9 ${\mu}{\textrm}{m}$).

This study examines the influence of long-range transport of dust particles and air pollutants on both local/regional DMS oxidation chemistry and the distribution of sulfur compounds at Jeju Island (33.17$^{\circ}$ N. 126.10$^{\circ}$ E) during the Asian dust-storm(ADS) period in April 2001. The atmospheric concentrations of these sulfur species were measured at a ground station on Jeju Island. Korea as Part of the ACE-Asia intensive operation. Three ADS events were observed during the periods of 10-12, 13-14. and 25-26 April. respectively. The concentrations of DMS and CS$_2$ were higher during the ADS period than during the non-Asian-dust-storm (NADS) period. Conversely. a difference in SO$_2$ levels during the ADS period was not distinguishable from those during the NADS period. The diurnal variation pattern of DMS observed was largely different from that in the remote marine boundary layer. DMS loss by NO$_3$ in the atmospheric boundary layer was dominant due to significantly high NOx levels influenced by the long-range transport of pollutants from East Asia to Jeju Island The DMS maximum during the ADS period was observed in the late afternoon. The oceanic fluxes of DMS during the ADS and NADS periods were estimated to be 5.7$\pm$2.3 and 2.9 (+2.8/-1.5) mole m$^{-2}$ day$^{-1}$ . respectively. The contribution of oxidized DMS to SO$_2$ levels at Jeju Island during the study period was found to be insignificant.

Background: The role of antidepressants (ADs) in bipolar disorder is long-standing controversial issue in psychiatry. Many clinicians have used ADs as a treatment for bipolar depression, and the selection of therapeutic agents is very diverse and inconsistent. This study aimed to examine recent AD prescription patterns for patients with bipolar disorder in Korea, using the nationwide, population-based data. Methods: This study utilized the Korean nationwide, whole population-based registry data of the year 2010, 2011, and 2013. All prescription data of the ADs, antipsychotics, and mood stabilizers of the sampled patients diagnosed with bipolar disorder (n = 2,022 [in 2010]; 2,038 [in 2011]; 2,626 [in 2013]) were analyzed for each year. Results: Annual prescription rate of ADs was 27.3%-33.6% in bipolar disorder, which was gradually increasing over the 3-year period. The combination pattern of ADs and antipsychotic drugs tended to increase over 3 years. The proportion of females and the prevalence of comorbid anxiety disorder were significantly higher in AD user group in all three years. Among individual ADs, escitalopram was prescribed most frequently, and fluoxetine and bupropion were prescribed to the next many patients. The mean duration of bipolar depressive episodes was 135.90-152.53 days, of which ADs were prescribed for 115.60-121.98 days. Conclusion: Our results show prescription rate of ADs in bipolar disorder was maintained at substantial level and increased in recent 3 years. More empirical data and evidence are needed to establish practical treatment consensuses.

This study investigates the developmental pattern of adhesive discs (ADs) to highlight the ontogeny and structural changes that occur during the growth of Boston ivy. Initiation to postmortem features of ADs were examined through light and scanning electron microscopy. The study also reveals a new finding of the dislocation of peripheral tissues of adaxial origin. Four phases of attachment are suggested with regards to its climbing behavior: 1) pre-attachment, 2) upon attachment, 3) after attachment, and 4) final attachment. During initiation, several ADs originate from tendril primordia without epidermal differentiation. However, different growth rates in the epidermis results in completely different ADs. ADs were discerned by size, shape, and color during expansion, but cells in the adaxial surface remained alive longer than the other side. Upon contact, the ADs demonstrate simultaneous growth and deterioration, but once attachment is established the latter process subdues to final stages. Epidermal transformation, adhesive secretion, cellular disruption, and mechanical stress were essential for the self-clinging nature of Boston ivy. The post-attachment sequence is also believed to be critical in achieving maximum mechanical strength to provide extensive support. The developmental process of ADs is prompted by tactile stimulation but in a highly organized and systematic manner.

항공교통관리에 있어서 ADS-B(Automatic Dependent Surveillance-Broadcast)와 multilateration은 국제민간항공기구에서 지정한 차세대 시스템 중 핵심기술이다. 그러나 오늘날, 모든 항공기가 ADS-B를 장착하고 있지는 않다. ADS-B 미장착 항공기의 위치 획득을 위해 TIS-B(Traffic Information Service-Broadcast)가 사용되는데, TIS-B는 레이더로부터 획득한 항공기 위치를 제공한다. 본 논문에서는 TIS-B를 대체할 수 있는 2차 감시레이더 신호를 활용한 onboard multilateration 시스템을 제안한다. TIS-B는 레이더 자료를 이용해 항공기 위치를 제공하므로 그 오차가 굉장히 큰 반면, onboard multilateration 시스템은 TDOA(Time Difference of Arrival) 기법을 이용하므로 항공기 위치 오차가 매우 작다. 성능비교 결과, 본 논문에서 제안된 onboard multilateration 시스템이 TIS-B에 비해 공항 인근에서는 37.39%, 공항 200마일 부근에서는 51.61% 성능이 우수한 것으로 나타났다.
