  • The objective of this study was to quantitatively evaluate the influence of the netting hanging ratio on fishing performance of gillnet. A total of six tests was carried out using three kinds of gillnets with different horizontal hanging ratios (0.3, 0.5 and 0.7) on the basis commercial gillnet of mesh size of 60 mm used in Yeosu Dolsan. As a result of the test fishing operation, catches of the net with hanging ratio 0.3 and the shortest float length was 1.34 times larger than the net with hanging ratio 0.7. The caught species in experimental testes was lager in the net with hanging ratio 0.3 than the net with hanging ratio 0.7. The catch rate per unit area (CPUE) is on the silver croaker with the largest catches in tests as follows. The net with hanging ratio 0.3 net was $89.45g/m^2$, hanging ratio 0.5 net was $41.63g/m^2$, and hanging ratio 0.7 net was $24.50g/m^2$. The net with hanging ratio 0.3 (float line length of 45 m) exhibited the largest CPUE value.

  • Hanging paintings are used for special ceremonies in Buddhist temple. They are stored in special storage box called "Gwaebulgwae" which means storage box for a hanging painting. Studies regarding pigments, background fibers and textiles of hanging paintings are carried out with many data in the field of conservation science. However, there are only few studies for the axes of hanging paintings and storage boxes. In this study, species identification for wooden axes of hanging paintings and storage boxes from the Joseon dynasty are carried out. Hanging painting of Beopjusa temple, Magoksa temple, Sudeoksa temple, Gaeamsa temple, Sudosa temple, Bukjangsa temple, Dorimsa temple, Tongdosa temple and Daeryeonsa temple are selected. Sampling is carried out from the axes of hanging paintings and storage boxes. 81 samples are collected from hanging paintings and storage boxes. As a result, 51 hard pines of Pinus spp., 8 Tilia spp., 6 Juniperus spp., 5 soft pines of Pinus spp., 4 Tsuga spp., 3 Pseudotsuga spp., 2 Berchemia spp., 1 Pyrus spp., 1 Bambusoideae are identified. Tsuga spp. and Pseudotsuga spp. might be used in conservation and restoration works in modern times because those species do not naturally grow in Korea. Most hanging paintings and storage boxes are made of hard pine. Also, some of are made of Tilia spp., because it represents the symbol of Buddha. Some unique kinds of trees used for wooden sculpture are identified, such as Juniperus spp. and Berchemia spp. Authentic conservation and restoration works could be carried out with this data-base.

  • Sling exercise treatment(S-E-T) is a therapeutic exercise based on scientific studies for the purpose of treating musculoskeletal or neurological disorders thereby improving strength, endurance, and skills for sensory-motor integration. Exercise resistance and intensity can be modified in various ways by changing the length of rope, patient position, therapist's manual resistance, and using elastic rope. The therapist can also progress to successively higher levels of exercise resistance and intensity by changing the position of the hanging point: the subject of this article. In brief, there are three axial components in S-E-T; hanging point, motor axis, and suspension point. The hanging point can be changed in several ways in relation to the joint; axial, superior, inferior, medial, and posterior hanging points. The position of the hanging point affects the amount of load on agonist and antagonist muscles as well as on the range of motion. To create an advanced exercise program, selection of hanging point can be two-dimensional such as superior-lateral or anterior-medial. Therapists, therefore, can freely but carefully select the best hanging point based on the purpose of the exercise and their level of knowledge in S-E-T.

  • Objectives: Hanging is a common method of attempted suicide. This study investigated the epidemiological profile of attempted and completed suicides by hanging in southern Iran. Methods: This cross-sectional study was performed on 1167 suicide attempts by hanging between 2011 and 2019. All data related to suicide attempts by hanging were collected from the Fars Suicide Surveillance System. The trends in suicide cases and the mean age of attempted and completed suicides were plotted. The chi-square test was used to identify suicide-related factors. Crude rates of incidence, mortality, and standardized fatality during the study period were calculated. Finally, logistic regression was used to identify the predictors of death in individuals who attempted suicide. Results: The mean age of those who attempted suicide was 33.21±16.82 years; the majority were male (80.5%). The rate of attempted and completed suicide by hanging were 3.50 and 2.79 per 100 000 people, respectively. The case-fatality rate was calculated as 79.34%. The results of our study indicated an increasing trend in suicide attempts by hanging. The likelihood of death was 2.28 times higher in individuals with a previous history of suicide attempts and 1.85 times higher in those with a psychological disorder. Conclusions: The findings of this study suggest an increasing trend in attempted and completed suicide by hanging, especially among individuals with a history of suicide attempts and psychological disorders. It is necessary to take action to reduce the rate of suicide attempts and identify the underlying causes of suicide attempts by hanging.

  • This study was carried out to investigate the effects of suckers on chemical components with vertical and horizontal hanging method during stalk-cut curing in burley tobacco. The elongation and dry weights of suckers were increased until 14 days in vertical hanging method, and until 7days in horizontal hanging method after the beginning of curing. The contents of nicotine, protein-N and $NH_4$-N were decreased at treatment of more suckers during the curing. However, there was no significant difference by the hanging method. Solanone, damascenone, megastigmatrienone and 4-methyl phenol were increased gradually during curing. Those were increased with treatment of fewer suckers compared to treatment of more suckers. There was no significant difference by the hanging method.

  • Hanging boards of the Joseon royal court are hung on buildings related to the royal family, such as palaces and Jongmyo Shrine, to show the hierarchy and character of the building. In addition, the manufacturing method and materials are recorded in the royal protocols of the Joseon Dynasty, so it is an important material for studying the manufacturing method and material changes at that time. However, the hanging boards were restored several times due to fire or war, and it is presumed that there is a change in the original form and material of the hanging boards. In particular, many hanging boards of the Joseon royal court were written with calligraphy by kings, so there are many forms consisting of gold letters on a black background. This study tried to analyze the pigments remaining in the letters of 44 of the Joseon royal hanging boards, which are presumed to be gold letters, and to find out the changes in the hanging board production method and materials by referring to the analysis results. The letters of the hanging boards studied were classified according to the current state of the gold pigment and the detected components. As a result of the analysis of character pigments, 24 embossing techniques and 5 intaglio techniques were mainly detected with gold (Au), but 15 embossing techniques were detected with brass (Cu, Zn). Only blue-green substances, not gold pigments, remain in some of the hanging boards in which brass components were detected. A reproduction experiment was conducted because the pigments of the brass component were not recorded in the literature and were not currently used as Dancheong pigments. In the reproduction experiment, it was difficult to confirm the application and use of brass pigments due to the limitations of materials, but it is judged that research on the timing and method of using brass pigments is needed in the future.

  • A hanging-type sand-retaining wall is a very common sand-blocking fence structure used to prevent sand movement. This type of wall is widely used along the Qinghai-Tibet and Gobi desert railways in Xinjiang, Western China. To analyze the characteristics of wind-sand flow fields under the effect of such a sand fence structure, a wind tunnel test and a field test were carried out. The wind tunnel test showed the zoning characteristics of the flow fields under the effect of the hanging-type sand-retaining wall, and the field test provided the sediment transport data for effective wind-proof interval and the sand resistance data in the front and behind the sand-retaining wall. The consistency of the wind-sand flow fields with the spatial distribution characteristic of wind-carried sand motion was verified by the correspondences of the acceleration zone in the flow field and the negative elevation points of the percentage variations of the sand collection rate. The spatial distribution characteristic of the field sand collection data further showed the spatial structural characteristic of the sandy air currents under the action of the hanging-type sand-retaining wall and the sand resistance characteristic of the sand-retaining wall. This systematic study on the wind-sand flow fields under the control of the hanging-type sand-retaining wall provides a theoretical basis for the rational layout of sand control engineering systems and the efficient utilization of a hanging-type sand-retaining wall.

  • Hanging sleepers are frequently observed in the ballasted track with the rail of high rigidity. These hanging sleepers at the high speed line could cause such large dynamic force compared to those at the conventional line. This dynamic force would, in turn, deteriorate train running stability as well as riding comfort, and accelerate irregularity of track and failure of track materials, leading to a sharp increase in track maintenance cost. When the wheel-rail contact spring exhibits nonlinear behavior and some components of the system like hanging sleeper exhibit bi-linear behaviors, an effective analytical method is proposed for train-track interactions. The verification of the present method is carried out comparing numerical results by the present method and those by Ono's method of RTRI.

  • This paper deals with one of the hottest debates in the history of the Association for Asian American Studies (AAAS) since its inception in the late 1960s. In 1998 at Hawai'i, the AAAS awarded Lois-Ann Yamanaka its Fiction Award for her novel Blu's Hanging, only to have this award protested. The point at issue was the inappropriate representation of Filipino American characters called "Human Rats" in the novel. This event divided the association into two groups: one criticizing the novel for the problematic portrayal of Filipinos in colonial Hawai'i, and the other defending it from the criticism in the name of aesthetic freedom. Such a "crisis of representation" in Asian American identity reflects on the ways in which local Hawaiians are positioned in the complicate power dynamic between oppositional Hawaiian identity and cosmopolitan diasporic identity within the larger framework of Asian American pan-ethnic identity. The controversial event triggered the eruption of Asian Americans' anxiety over the identity-bounded nation of Asian America where intra-racial classism and conflict have been at play, which are primary themes of Blu's Hanging. This paper shows how Yamanaka's Blu's Hanging becomes so disturbing a work to prevent the hegemonic formality of Asian America identity from being fully dogmatic. Ultimately, it contradicts the political unconscious of the reading public and unmasked its false consciousness by engendering a "free subjective intervention" in the ideological reality of colonial Hawai'i.
