Objectives The purpose of this study is to provide data for development of the korean medicine (KM) clinical practice guidelines (CPG) for growth disorder (GD) by identifying the awareness and knowledge needs of KM doctors (KMD) through online survey. Methods Survey questionnaire was produced by referring to the previous recognition survey studies for clinical KMDs. The survey questionnaire was composed 18 questions regarding the current status of clinical care for GD, clinician's knowledge level about GD, and other details that clinicians use during practice. The survey was conducted from January 2021 to March 2021. An online survey was conducted on 101 KMDs from the association of pediatrics of KM. Results According to the survey, 96 respondents (40.3%) said the causation of GD without growth hormone deficiency needs to be included in CPG. 96 (23.5%) of the respondents wishes to utilize percentile in diagnosis and evaluation of the growth assessment. 24.7% of the clinicians were using the herbal medicine treatment. Currently, when treating with KM for GD, herbal medicine (100%) is the most widely used, followed by acupuncture (77.6%), and moxibustion (36.7%). In terms of a complex treatment, growth therapy efficacy (26.8%) is shown to be the most important factor to consider and needed to be included in CPG for the complex treatment, and diet (22.3%) is also considered to be important in GD. Conclusions In this study, we were able to understand the clinical KMDs' perception of GD, knowledge level, and the requirements in the CPG. The results of this study will provide the basic data for development of CPG for GD.

Decreasing response rates to traditional survey methods, like face-to-face and telephone interviews, have led survey practitioners around the world to seek new ways of conducting surveys in recent years." The COVID-19 pandemic exacerbated this problem because it made conducting face-to-face interviews even more difficult than before. For example, it made conducting face-to-face surveys infeasible in 2020 in South Korea, and so the Korean Academic Multimode Open Survey (KAMOS) was unable to conduct a planned face-to-face survey to recruit new panel members. The entire 8,514-member panel, established via two-stage probability-based sampling from 2016 to 2019, was invited to take three online/telephone surveys in 2020. Of these panel members, 1,352 responded to at least one survey in 2020. To test to what extent the panel remained representative of the adult South Korean population, we compared the two groups of panel members: those who responded to at least one survey in 2020 and those who did not. After weighting both groups on the basis of age, sex, and geographical area, we analyzed their responses to some of the questions that were asked during multiple rounds of the face-to-face panel-recruiting interviews. Using Cohen's d for survey items that could be analyzed numerically and Cramér's V for categorical items, we were able to conclude that the respondents to the 2020 surveys were equivalent to the non-respondents in terms of both demographics and in the answers they originally gave to substantive questions on a variety of topics related to social science or public opinion research, including questions about quality of life, societal issue, and politics (Cohen's d items <0.2, 95% CI; Cramér's V items <0.1, 95% CI). This analysis may provide a model for others who wish to test the continued representativeness of their panel or who would like to use a different survey mode or change some other aspect of their methodology and test whether it is equivalent to their former methodology. Our success in building a panel that retained its representativeness may be useful to those in other countries where face-to-face surveys had previously been the norm but are becoming increasingly difficult to conduct.

Objectives: This longitudinal study was done to identify the relationship of school adjustment and sponsor support or future time perspective and the differences of these 3 variables between 1st and 2nd survey of children having Didimseed account in institutional care. Methods: Participants were 25 elementary fourth to sixth grade children who are living on one facility that located in G. metropolitan area at 1st survey and 2nd survey was done at five-year intervals. Data were collected from September 2012 to September 2017 and were analyzed using t-test, paired t-test, ANOVA, post-hoc test and Pearson's correlation coefficients. Results: The level of school adjustment knowledge was not different significantly according to grade, gender and admission period at 1st survey. At 2nd survey, the level of school adjustment was different significantly according to grade only. The level of school adjustment was associated with positive future time perspective(r=.74) and negative future time perspective(r=-.54) at 1st survey, and that was associated with negative future time perspective(r=-.49) and meeting frequency of sponsor(r=-.43) at 2nd survey. There were not significantly different school adjustment and future time perspective variables between both surveys. But meeting frequency of sponsor at 2nd survey was lower significantly than that at 1st survey. Conclusions: Based on the results of this study, it would be necessary to prepare the policies that could have their positive future time perspective to increase school adjustment of institutionalized children. Also the effective strategies to increase not only Didimseed account support but emotional support through qualified meeting with sponsors should be developed.

Jakarta is the capital city of Indonesia which has problems of land subsidence with the rates of about 1 to 15 cm/year, up to 20-25 cm/year. The study has examined the land subsidence in Pantai Mutiara, Jakarta Bay which is a reclaimed area by using the Terrestrial LIDAR survey technique. The Terrestrial LIDAR survey results show that the survey site has mean elevation of 0.24 m with the highest elevation of 0.93 m and lowest - 0.35 m. Considering that AHHW (approximate highest high water) is 0.51 m, many areas of the survey site are lying below the AHHW. Pantai Mutiara area is showing various subsidence rates depending on sites although the site is relatively narrow and small (about 1 $km^2$). There is elevation differences of almost 1m within the site. In this study, key information including topography, dike height distribution, and future coastal flooding risk of the survey area was able to be provided by Terrestrial LIDAR survey conducted only once. Especially, as the 3D precision topography effectively conveys important messages relating to vulnerability of the site, policy makers and stakeholders can easily understand the situation of the site.

The first all-sky mid-/far-infrared survey by IRAS in the 1980s, has been followed by only two more, by AKARI, from 2006, and WISE in 2010. I discuss some features of the WISE survey, and highlight some key results from early extragalactic observations that have been made by the science team during the operation of the telescope, and the post-operation proprietary period during which the public release data products were being generated. The efficient survey strategy and very high-data rate from WISE produced a catalogue of 530 million objects that was released to the public in March 2012. The WISE survey strategy naturally provided the deepest coverage at the ecliptic poles, where matched comparison fields were obtained using Spitzer, and where AKARI also observed deep fields. I describe some of the follow-up work that has been carried out based on the WISE survey, and the prospects for enhancing the WISE data by combining the AKARI survey results are also discussed. While the all-sky AKARI survey is less deep than the WISE catalogue, and is still being worked on by the AKARI science team, it includes a larger number of bands, extends to longer wavelengths, and in particular has very complementary band passes to WISE in the mid-infrared waveband, which will provide enhanced spectral information for relatively bright targets.

Galaxy clusters, the largest gravitationally bound systems, are an important means to place constraints on cosmological models. Moreover, they are excellent places to test galaxy evolution models in connection to the environments. To this day, massive clusters have been found unexpectedly at high redshfit (Kang & Im 2009, Durret et al. 2011, Tashikawa et al. 2012), and evolution of galaxies in cluster has not been fully understood. Finding galaxy cluster candidates at z > 1 in wide, deep imaging survey data will enable us to solve such issues of modern extragalactic astronomy. We report new candidates of galaxy clusters in the wide and deep survey fields, European Large Area ISO Survey North1(ELAIS-N1) and North2(ELAIS-N2) fields, covering sky area of $8.75deg^2$ and $4.85deg^2$ each. We also suggest a new useful colour-colour selection technique to separate 1 < z < 2 galaxies from low-z galaxies by combining multi-wavelength data from the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey (UKIDSS DXS, JK bands), Spitzer Wise-area InfraRed Extragalactic survey (SWIRE, Optical-Infrared bands), Canada France Hawaii Telescope (CFHT, z band) and Infrared Medium-deep Survey(IMS, J band).

Hydro-acoustic survey was carried out to investigate the spatial characteristics of fish distribution near two artificial reefs (AO: large octagonal semi-sphere and AC: combined custom built) having different types in Jeju marine ranching area. The survey system consisted of scientific echo sounder (EK60), DGPS system, and ECDIS (Mecys). Field survey was conducted on August and October 2012 with star survey and line transect survey line method, and species composition was investigated from gill net fishing survey. The acoustic signals from individual fishes and small fish schools were mainly recorded around AO, but large and strong signals from large fish school were mainly detected in the top layer of and the water column near AC. The echogram suggest that the fish aggregation for the two types of AO and AC exist the significant difference in fish species and spatial distribution pattern.
