The latest revision of AS/NZS 1170.2 incorporates some new research and knowledge on strong winds, climate change, and shape factors for new structures of interest such as solar panels. Unlike most other jurisdictions, Australia and New Zealand covers a vast area of land, a latitude range from 11° to 47°S climatic zones from tropical to cold temperate, and virtually every type of extreme wind event. The latter includes gales from synoptic-scale depressions, severe convectively-driven downdrafts from thunderstorms, tropical cyclones, downslope winds, and tornadoes. All except tornadoes are now covered within AS/NZS 1170.2. The paper describes the main features of the 2021 edition with emphasis on the new content, including the changes in the regional boundaries, regional wind speeds, terrain-height, topographic and direction multipliers. A new 'climate change multiplier' has been included, and the gust and turbulence profiles for over-water winds have been revised. Amongst the changes to the provisions for shape factors, values are provided for ground-mounted solar panels, and new data are provided for curved roofs. New methods have been given for dynamic response factors for poles and masts, and advice given for acceleration calculations for high-rise buildings and other dynamically wind-sensitive structures.

Reports of a global decline in pollinator populations, especially mason bees, have raised concerns regarding the maintenance of pollination interactions. Although addressing local factors causing bee decline is a potential mitigation strategy at the landscape scale, regional rates and high-latitude threats to bee diversity are unclear. We investigated the distribution of mason bees (Osmia. spp. (O. pedicornis, O. corniforns, O. taurus, and O. satoi) and measured species richness and species ratios at regional, latitudinal, and altitudinal scales. We examined the association between bee species richness and three putative environmental conditions: high-low, altitude-dependent, and latitude-dependent. The species richness of the O. pedicornis bee was the highest and it was found between latitudes 35° and 37°, and at 500-600 m in both the northern and southern hemispheres, showing an inverse latitudinal gradient of bee species richness in South Korea. Mason bee species richness and global climate are important predictors of flowering plant diversity. Climate change threatens bee and vascular plant diversity; however, the overlap between bee abundance and plant diversity can be improved by employing suitable conservation strategies.

Domestic agriculture is facing real problems, such as a decrease in the population in rural areas, a shortage of labor due to an aging population, and increased risks due to the deepening of climate change. Smart farming technology is being developed to solve these problems. In the development of smart agricultural technology, irrigation control plays an important role in creating an optimal growth environment and is an important issue in terms of environmental protection. This paper is about the study of collecting and analyzing the rhizosphere environmental data of domestic paprika farms for the purpose of improving the quality of crops, reducing production costs, and increasing production. Irrigation control modeling presented in this paper Control modeling is to graphically present changes in a medium weight, feed, and drainage due to regional climatic features. To derive the graph, the parameters were determined through data collection and analysis, and the suggested irrigation control modeling method was applied to the collected rhizosphere environmental data to control irrigation in 6 regions (Gangwon-do, Chungnam, Jeonbuk, Jeonnam, Gyeongbuk, and Gyeongnam). The parameters were obtained and graphs were derived from them. After that, a study was conducted to analyze the derived parameters to verify the validity of the irrigation control modeling method and to correlate them with climatic features (average temperature and precipitation).

With the increasing demand for improved marine environments and safety, greater ability to minimize damages to coastal areas from harmful organisms, ship accidents, oil spills, etc. is required. In this regard, an accurate assessment and understanding of current systems is a crucial step to improve forecasting ability. In this study, we examine spatial and temporal characteristics of current systems in the adjacent seas of Jeju Island using a high-resolution regional ocean circulation model. Our model successfully captures the features of tides and tidal currents observed around Jeju Island. The tide form number calculated from the model result ranges between 0.3 and 0.45 in the adjacent seas of Jeju Island, indicating that the dominant type of tides is a combination of diurnal and semidiurnal, but predominantly semidiurnal. The spatial pattern of tidal current ellipses show that the tidal currents oscillate in a northwest-southeast direction and the rotating direction is clockwise in the adjacent seas of Jeju Island and counterclockwise in the Jeju Strait. Compared to the mean kinetic energy, the contribution of tidal current energy prevails the most parts of the region, but largely decreases in the eastern seas of Jeju Island where the Tsushima Warm Current is dominant. In addition, a Lagrangian particle-tracking experiment conducted suggests that particle trajectories in tidal currents flowing along the coast may differ substantially from the mean current direction. Thus, improving our understanding of tidal currents is essential to forecast the transport of marine pollution and harmful organisms in the adjacent seas of Jeju Island.

To make a preliminary identification of the gracilarioid plant attached to cultivation ropes of Undaria pinnatifida and establish a method of cultivating this plant, the first taxonomic and cultivation studies on this species in Korea were conducted. This gracilarioid plant was identified from its morphological and anatomical features, as Gracilaria chorda. Growth tests using the 10, 20, and 30 cm cuttings of axes of G. chorda were performed twice, from May 3 to August 21, 2002 and from December 15, 2002 to April 3, 2003 in Ihoijin aquafarm, Hoijin, Jangheung, Jeollanamdo, Korea. In the first growing test, the thallus length of the 10, 20, and 30 cm cuttings increased twelve-fold, ten-fold, and seven-fold; the wet weight increased 81-fold, 60-fold, and 41-fold; the numbers of more than 10 cm-long branches increased 3.8-fold, 5.2-fold, and 6.1-fold, respectively. In the second growth test, the thallus length of the 10, 20, and 30 cm cuttings increased seven-fold, 5.5-fold, and four-fold; the wet weight increased 81-fold, 53-fold and 36-fold; the number of branches increased 3.8-fold, 7.3-fold, and 6.6-fold, respectively. The cultivation of G. chorda by vegetative regeneration using cuttings of thallus axes was successful for the first time in Korea.

This study was to analyze the social identity described in the dress of the American novelist Pearl S. Buck's (1892-1973) major works. A novelist pursues varying and refined expressions in an effort to convey to readers the character' identities of his or her own creation. In particular, Pearl S, Buck was a great writer who was awarded the Novel Literature Prize, and since her work The Good Earth recorded a world-wide bestseller, she might well be called a popular novelist. She depicted well her characters' identities from divers viewpoints with her unique delicacy and realistic expressions. For this study, the following seven works which are considered to feature the dresses for character's identity well were selected out of her 85 works: The Good Earth (1931), Sons(1932), The Mother (1934), A Housed Divided (1935), The Hidden Flower (1952), Love and the Morning Calm (1953) and Letter from Peking (1957). For an analytical tool, the content analysis method was used. In order to systematically review the social identity described in the dress individuals' identity were classified into the following categories based on the identity theories: Social identity were divided into ① age identity ② sex, gender identity ③ economic identity ④ occupational identity ⑤ political identity ⑥ religious identity ⑦ kinship identity ⑧ regional identity. The characters' age identity, sex, gender identity, economic identity, occupational identity, political identity, religious identity, kinship identity, regional identity were depicted by their dresses and physical features. All in all, it is hoped that this study would provided important cues to the understanding of the other party's identity through his or her dresses in mutual relationship: It is believed that this study would be useful because they are arranged through the analysis of the dresses featured in the great writer's works using a consistent framework of analysis.

Today human rights are the most complex and prominent issue in the system of international law, and the right to housing(housing right) is also recognized as a basic human right in the international human right instruments including the Universal Declaration of Human Rights. This study targets to comprehensive review of the housing rights provisions with 85 international human rights laws and instruments. And the contents and characteristics of housing rights are analyzed with categorization based on housing rights in general, housing rights of workers, socially vulnerable groups, international regional organizations. Housing right takes also the features of universality, indivisibility, interdependence, and right to adequate housing should be interpreted with holistic view including legal security of tenure, accessibility, affordability, location beyond ensuring just a physical housing space. Approaches to the housing right comprehensively reflect the view of the right to development, the perspective of gender equality, the principle of non-discrimination, the participation rights, and orient the housing right should be seen as the right to live somewhere in security(safety), peace and dignity.

Complex Regional Pain Syndromes (CRPS) type I and type II are neuropathic pain conditions that are being increasingly recognized in children and adolescents. The special distinctive features of pediatric CRPS are the milder course, the better response to treatment and the higher recurrence rate than that of adults and the lower extremity is commonly affected. We report here on a case of pediatric CRPS that was derived from ankle trauma and long term splint application at the left ankle. The final diagnoses were CRPS type I in the right upper limb, CRPS type II in the left lower limb and unclassified neuropathy in the head, neck and precordium. The results of various treatments such as medication, physical therapy and nerve blocks, including lumbar sympathetic ganglion blocks, were not effective, so implantation of a spinal cord stimulator was performed. In order to control the pain in his left lower limb, one electrode tip was located at the 7th thoracic vertebral level and two electrode tips were located at the 7th and 2nd cervical vertebral levels for pain control in right upper limb, head, neck and right precordium. After the permanent insertion of the stimulator, the patient's pain was significantly resolved and his disabilities were restored without recurrence. The patient's pain worsened irregularly, which might have been caused by psychological stress. But the patient has been treated with medicine at our pain clinic and he is being followed up by a psychiatrist. (Korean J Pain 2007; 20: 60-65)

The academic values of Joseon jiji jaryo (Geographical Documents of Joseon) are that native Korean toponyms corresponding with toponyms in Sino-Korean characters (hanzi 漢字) are abundantly recorded nationwide. Through analysing these documents, it is able to examine the linguistic features of toponymic changes while reasoning about geographical named sources and administrative districts as well as obtaining primary data. This article aims to preliminarily analyze these documents for encouraging academic studies which haven't been investigated sufficiently since they was introduced into the academic world. Noticing the toponymic values of these documents, I reexamined the bibliography and composing contents centering around the volume of Chungcheongbuk-do province in these documents. Consequently, I pointed out the possibility of regional differences of compilation times and mistakes in the contents of these documents. In addition to that, I proposed the toponymic values, referring to the transcription changes of village toponyms and the tendencies of loan transcription.

Procedures involved in the refinement of the regional geoid for the area encompassing the Korean peninsula and the East Sea are described, and the computational results are provided. A comparison between the geoid height data, the mean sea surface height and the final product of the refinement work is provided and analyzed. The regional marine geoid thus refined seems to have a better resolution, in terms of its correlation with the bathymetry, and shows the bottom features in a more detailed manner when compared with previously used procedures. The general pattern of the computed geoid profile matches reasonably well with the existing studies, where the correlations between the refined regional marine geoid and the bathymetry are (1) 0.44 for the area $117{\sim}142.5^{\circ}E/24{\sim}52^{\circ}N$ and (2) 0.47 for the area $127{\sim}142.5^{\circ}E/32{\sim}50^{\circ}N$ in the East Sea respectively.
