Purpose : Acute interstitial pneumonia (AIP) is a rare disease, but its prognosis is fatal because of lack of efficient treatment modality. Recently, it has been reported that there was epidemic AIP in Korea. This study aims to investigate the past and current status of AIP in Korea. Methods : We performed a nationwide survey and a prospective study. From August 6 to 15, 2008, a questionnaire survey was conducted to identify the prevalence, local distribution, and response to current treatments. The questionnaire was answered by pediatrician working in 23 referral centers in Korea. In addition, 5 referral centers in Seoul performed a preliminary prospective observational study by obtaining clinical data and specimens from appropriate patients. The Korea Centers for Disease Control and Prevention analyzed the samples for possible pathogens. Results : The survey showed 78 AIP cases had occurred and 36 patients had died. Lung biopsy was performed only on 20 patients. In 2008, 9 AIP cases developed. In a prospective study, 9 (M:F=5:4) patients developed AIP in spring and 7 (78%) died, with the mean rate of death occurring 46 days after diagnosis. Human corona virus 229E, cytomegalovirus, influenza A virus, influenza B virus, and parainfluenza virus were isolated from the respiratory specimens. Conclusion : This study showed nationwide prevalence of AIP in Korea. In addition, because of the high mortality rate and rapid progress, pediatricians need to be aware of the disease. Further studies and a nationwide network are required for reducing the morbidity and mortality rates related to AIP.

Objectives : The purpose of this survey is the development on the neck pain for acupuncture and moxibustion clinical guideline. Methods : The survey questionnaire was developed by the committee of experts who major in acupuncture & moxibustion or statistics for acupuncture clinical trial protocol development. The questionnaires were distributed via e-mail to 75 members of Korean Acupuncture & moxibustion society. 57 members completed answers, and the computerized data were analyzed by SPSS 17.0 statistical program. Results and Conclusions : 1. The first selected pattern identification on the neck pain This study shows that the meridian pattern identification was selected 35 times(61.4%), the pattern identification based on cause of disease was selected 8 times(14.0%), the visceral pattern identification was selected 7 times(12.3%), the other pattern identification was selected 4 times(7.0%), Qi blood yin yang pattern identification was selected 2 times(3.5%), according to symptoms was selected 1 time(2.4%). 2. Meridian pattern identification Small intestine meridian of hand Taeyang was used 39 times(18.1%), Large intestine meridian of hand Yangmyeong and Bladder meridian of foot Taeyang was used 34 times(15.7%), Gall-bladder meridian of foot Soyang was 32 times(14.8%), Tripple energizer meridian of hand Soyang was used 31 times(14.4%), Governor meridian was used 30 times(13.9%), Lung meridian of hand Taeeum was used 8 times(3.7%), Heart meridian of hand Soeum and Pericarduim meridian of hand Gworeum was used 4 times(1.9%). 3. Pattern identification based on cause of disease Wind-Cold-Dampness was used 31 times(17.5%), Accumulation of the collateral by Phelgm-Dampness was used 16 times(14.0%), affection by exopathogen Wind-Cold(stiff neck, sprain of cervical) was used 13 times (11.4%), Defecient-Cold was used 10 times(8.8%), affection by exopathogen Wind-Dampness was used 9 times(7.9%), Deep Invasion by Wind-Cold was used 8 times(7.0%), Wind-Cold was used 7 times (6.1%), Wind-Cold was used 6 times(5.3%), Accumulation in the Center by Phelgm-Dampness, Imparement of bou fluid by Pathogenic Heat, Wind-Heat with Dampness was used 5 times(4.4%), affection by exopathogen Wind-Dampness and Accumulation of the collateral by Wind-Cold was used 4 times(3.5%), Invasion of Dampness-Heat was used 2 times(1.8%). 4. Visceral pattern identification Rising of the Liver yang was used 16 times(41%), Yin deficiency of Liver and Kidney+pathogens was used 15 times(38.5%), Yin deficiency of Liver and Kidney was used 8 times(20.5%) on this survey.

The objective of this study was to realize research demands by gathering the research agenda from the Korean Dental Hygienists Association and affiliated groups through a Delphi survey. The study subjects were the heads of eight groups. The Delphi survey was conducted by e-mail after a researcher explained the objective of the study to the heads. The research agenda was classified according to the Korean dental hygiene academic classification and the National Dental Hygiene Research Agenda classification. To compare the number of research agendas according to classification among the groups, we conducted a chi-squared test by using IBM SPSS 20.0. In total, 316 agendas were submitted. According to the Korean dental hygiene academic classification, there was a significant difference among the groups, and the agendas associated with clinical dental hygiene (36.7%) were the best. According to the National Dental Hygiene Research Agenda classification, there was no significant difference and the agendas associated with health promotion and disease prevention (27.8%) were the best. In conclusion, the Korean Dental Hygienists Association and affiliated groups demanded similar research agendas, corresponding to the purpose of each establishment. However, the groups did not seem to show unique characteristics according to the purpose of each establishment. In other words, the groups should corroborate such characteristics and suggest a corresponding agenda to establish specific areas of research in dental hygiene. Also, dental hygiene researchers should mark the academic classification of the studies they want to submit.

Recently, import and export companies have been using T/T remittance and Surrender B/L more frequently than L/C when selecting the process and method of trade payment settlement. The new trade and logistics environment is thriving in the era of the Fourth Industrial Revolution (4IR). Document-based trade transactions are undergoing a digitalization as bills of lading or smart contracts are being developed. The purpose of this study is to verify whether exporters choose export payment types based on negotiating factors. In addition, we would like to discuss the application of the characteristics of the new trade and logistics environment. Data for analysis was collected through surveys. The collection method consisted of direct visits to the company, e-mail, fax, and online surveys. The survey distribution period is from February 1, 2023, to April 30, 2023. The questionnaire was distributed in 2,000 copies, and 447 copies were collected. The final 336 copies were used for analysis, excluding 111 copies that were deemed inappropriate for the purpose of this study. The results of the study are shown below. First, among the negotiating factors, the product differentiation of exporters did not significantly affect the selection of export payment types. Second, among the negotiating factors, the greater the purchasing advantage recognized by exporters, the higher the possibility of using the post-transfer method. In addition to analyzing the results, this study suggests that exporters should consider adopting new payment methods, such as blockchain technology-based bills of lading and trade finance platforms, to adapt to the characteristics of the evolving trade and logistics environment. Therefore, exporters should continue to show interest in initiatives aimed at digitizing trade documents as a response to the challenges posed by bills of lading. In future studies, it is necessary to address the lack of social awareness in Korea by conducting advanced research abroad.
