When we think about an idea of United Nations Tolerance Program UNTP, it is important for us to share memory with world citizens that we had 2314 veterans from 11 countries in the Busan U.N. Forces Cemetery since January of 1951. Recently, we had 13 veterans, who got buried coming from 4 Americans, 3 Hollanders, 2 Frenchmen, 2 Germans, 2 Englishmen, 1 Canadian and 1 headband after they died in their countries. (Joongang daily newspaper June 19, 2022). "I believe that creating a fifth office of the UNTP in Republic of Korea (Seoul, Busan, Kyunggi or Jeju Island), as a twin organization of the UNEP in Nairobi, Kenya, would provide a geopolitical balance to the international organization and a useful base for peace island studies in the conflict laden region of East Asia. Establishing this office in S. Korea(Seoul, Busan, Kyunggi or Jeju Island), with its unique geographical location as a hub for peace talks and environmental negotiations between Russia, North Korea, Japan, China, and Taiwan, would contribute to peace and development in the region." (Yates. 2022).

To investigate the tolerance limit and critical thermal maximum (CTM), behavioral responses of wild goldeye rockfish Sebastes thompsoni according to exposure to high water temperature were observed using a continuous behavior tracking system. As a result, behavioral index (BI) of S. thompsoni in each temperature (20.0, 25.0, and 30.0°C) showed a significant difference (p<0.05) when compared with the value measured in a stable condition of 15.0°C. The activity level of S. thompsoni exposed to 25.0°C decreased sharply after 20 hours. Their rest time at the bottom of experiment chamber increased, and their normal swimming and metabolic activities were disturbed. In addition, at a high water temperature of 30.0°C, S. thompsoni reached the limit of resistance and showed a sub-lethal reaction of swimming behavior, with energy consumption in the body increased and all test organisms died. In conclusion, the eco-physiological response of S. thompsoni to water temperature varied greatly depending on the fluctuation range of the exposed temperature and the exposure time. In addition, the tolerance limit of S. thompsoni to high water temperature was predicted to be 25.0- 30.0°C. The maximum critical thermal that had a great influence on the survival of this species was found to be around 30.0°C.

시설재배지 고추(Capsicum annuum)에 주요 총채벌레는 꽃노랑총채벌레(Frankliniella occidentalis)와 대만총채벌레(F. intonsa)이다. 본 연구는 이들 총 채벌레의 월동 생리를 분석하는 데 목적을 두었다. 두 총채벌레는 동결감수성 곤충으로 낮은 저온(-15~-25°C)에서 체내빙결점을 보였다. 그러나 이 체내빙결 점은 두 종 사이에 그리고 발육태에 따라 상이하였다. 꽃노랑총채벌레의 경우 성충 -25.7±0.5°C, 번데기 -17.2±0.3°C, 약충 -15.0±0.4°C였고 대만총채벌레 는 성충 -24.0±1.0°C, 번데기 -27.0±0.5°C, 약충 -17.2±0.8°C에서 체내빙결점을 기록하였다. 그러나 실제로 두 종의 저온 피해는 체내빙결점보다 높은 온도 에서 일어났으며, 처리온도가 내려갈수록 그리고 노출시간이 증가할수록 증가하였다. 대만총채벌레에 비해 꽃노랑총채벌레가 저온에 대해서 높은 내한성을 보였으며 발육태에 따라 약충보다는 성충이 높은 내한성을 나타냈다. 그러나 두 종 모두는 치사 저온조건(-10°C, 2시간)에 노출되기 전에 0°C에서 2시간 미리 노출되면 저온 피해가 현저하게 줄어드는 급속내한성유기를 보였다. 또한 단계적으로 감소하는 저온에 노출되면서 저온순화를 발현하였다. 이들 총채벌레의 월동처를 알아보기 위해 시설재배지 안팎에서 동계모니터링이 진행되었다. 동계기간(11월~2월) 두 종 성충은 야외에서 채집되지 않았지만, 시설재배지 내부 에서는 꽃노랑총채벌레가 황색점착트랩과 잡초에서 포획되었다. 동계기간 시설재배지 토양시료에서 꽃노랑총채벌레 성충이 지속적으로 우화되었으나, 대만 총채벌레는 11월과 12월 토양시료에서 나오지 않았지만, 1월 이후 채집된 시료에서 성충 우화가 관찰되었다. 휴면에 따른 우화율 차이인지를 분석하기 위해 상이한 일장을 이들 두 총채벌레 종에 처리하였다. 이 결과 꽃노랑총채벌레는 일장조건과 무관하게 우화한 반면 대만총채벌레는 단일조건에서는 우화하지 않 았다. 한편 이들 총채벌레가 전파하는 Tomato spotted wilt virus도 동계기간 총채벌레가 채집된 잡초에서 검출되었다. 이상의 결과는 꽃노랑총채벌레가 겨 울기간 시설재배지 내부에서 잡초를 먹이로 발육하는 반면, 대만총채벌레의 경우는 휴면상태로 토양 속에서 월동하는 것으로 추정되었다.

The objective of this study was to determine effects of phosphorus on lignification and carbohydrate metabolism in Kentucky bluegrass under drought stress. Drought stress was induced by reducing of water to plants in pots. Two types of phosphorus were applied as potassium phosphate (PO4 3-; P) or potassium phosphonate (PO3 3-; PA) in drought-stressed plants. Drought had significant negative effects on plant growth, as revealed by reduced biomass of shoot. Drought-induced increase of lignin content was concomitant with the increase of phenylalanine ammonia-lyase (PAL). Soluble sugar content was highly increased but fructan content was largely decreased by drought stress. However, the application of phosphorus was efficient to ameliorate the adverse effects of drought. PA application improved reduced shoot growth and relative water content, and inhibited lignification synthesis with a reduction of PAL activity. P or PA application maintained soluble sugar and fructan content at similar levels to controls under drought stress. These results indicate that phosphorus application may mitigate the drought stress by inhibiting the lignification and promoting the fructan assimilation.

We assume that, even though Jeju Island ‘Peace’ Cherry Trees (1913), happened at different time and places, it connects each other as (1919) and Busan UN Forces Cemetery (1951) as an important connected diplomatic event of Provisional Government and Republic of Korea positively. Especially, it will bring a significant positive impact to Asia Community if we organize 2023 Korean Week Event: The First Korea Congress (1919) and Busan UN Forces Cemetery (1951) and suggest the invitation issues of UN Asia Headquarters to the Republic of Korea (2023) into Busan metropolitan city(Seoul, Kyunggi, Jeju Special Self-Governing Province) of Republic of Korea. We also assume Korean’s tolerance philosophy will Koreans to unite each other together if they will succeed to share spirit of tolerance from Busan UN Forces Cemetery. We have 2314 graves from 11 countries at the graveyard for UN Forces in Busan, which was built as the UN Headquarters Cemetery in January of 1951 and used as memorial space for participation in the Korean War, who had involved the War beyond their sacrifices. Recently we had 13 veterans, who got buried coming from 4 Americans, thre Hollanders, 2 Frenchmen, 2 Germans, 2 Englishmen, 1 Canadian and 1 headband after they died in their countries. (Joongang daily newspaper June 19, 2022). In the end they become Asian spirit of Toleran명 at the Busan UN Forces Cemetery beyond borders.

This study introduces the Three-Memory-Model (Cherry, 2019) in education into Maritime Simulator- based training in Sri Lanka and conducts empirical research. In simulator-based education what is disseminated as knowledge during the Briefing, Scenario and Debriefing phases must be transferred from short-term, across working memory to long-term-memory. Working memory gained during the scenario phase, could be encoded into long-term-memory through rehearsal probes. But the number of probes which could be tolerated by the participants of simulator-based training has not undergone empirical investigation. Thus, selecting the Open Sea scenario phase as its setting the research questions aim to identify tolerance limits in the participants for the number of freezes and the number of probes introduced during each freeze. The methodology selects a population of seafarers (n = 60). Through stratified random sampling this population was subdivided based on experience at sea as Group A (n = 30): Mean of 2 years and Group B (n = 30): Mean of 13.6 years of sea experience. The duration of the open sea scenario phase is 35 minutes with freezes at 10-minute intervals. The number of probes were given a range of 7 to. Data analysis utilized SPSS. The highest percentage mean value was obtained for three freezes for the Open Sea scenario phase while two freezes had the next highest percentage mean value. The mean value of the tolerance limits for questions during one freeze is approximately 9 and 6 probes for Group A and B respectively. Citing prior research on working memory, visuo-spatial vs. verbal working memory, reaction time and age this study raises a counter argument against the findings: the self-declared tolerance limits of the number of questions the participants feel comfortable to answer during each freeze. The findings of this research are valuable to maritime Simulator-based instructional designers outside and within Sri Lanka.

In this study, using a continuous behavior measurement technique, the short-term behavioral responses and tolerance limits of red seabream Pagrus major fingerlings to sudden exposure to low salinity in a controlled environment were observed. The activity of the fingerlings suddenly exposed to 21.4, 17.3, and 9.8 psu increased temporarily at the initial exposure to show irregular swimming behavior, but then recovered a stable activity pattern through rapid salinity adaptation. However, the organisms suddenly exposed to 7.3 and 4.3 psu could not withstand the salinity stress, and their swimming behavior was severely disturbed and all individuals died within 48 hours. The findings suggest that red seabream underwent a temporary salinity stress process at the beginning of the exposure to concentrations of 10.0 psu or higher. At these concentrations, osmotic control was possible within at least 11 hours, so stable metabolic activity was also possible. However, organisms suddenly exposed to concentrations below 5.0 psu exceeded the tolerance to low salinity and the sublethal limit. In red seabream exposed to this concentration range, severe behavioral and metabolic disturbances were observed, and death was observed due to osmotic control failure. In conclusion, a salinity range of 5.0 to 10.0 psu can be predicted to correspond to a concentration range in which the osmotic control ability of the red seabream fingerlings is lost, and sub-lethal reactions occur.

본 연구에서는 토마토 유전자원 49점을 대상으로 엽록소형 광 측정 프로토콜인 Quenching act 2를 이용하여 염류 스트레스 수준을 구분할 수 있는 엽록소형광 매개변수를 선발하기 위해 수행되었다. 염류 스트레스 평가는 3엽기 유묘 단계의 토마토 유전자원 49점을 대상으로, 1일 1회 NaCl 400mM로 저면관수를 처리하였다. 염류 스트레스 처리 4일차에 토마토 유묘의 지상부 생체중, 엽록소 및 프롤린 함량 분석을 실시하였 다. 토마토 유전자원 49점의 지상부 생체중 및 엽록소 함량은 대부분 감소하였으며, 프롤린 함량 증가율은 유전자원 별로 유사하였다. 대표적인 12개의 엽록소형광 매개변수는 염류 스트레스에 노출되는 기간이 길어질수록 증감하는 경향을 보였으며, 염류 스트레스에 노출될수록 Y(NO)는 증가하였다. 본 연구결과에서 유전자원 49점의 광계Ⅱ의 비조절 에너지 소산의 양자 수율[Y(NO)]은 염류 스트레스 하에 차이를 보였으 며, 염류 스트레스에 저항성을 지닌 염류 저항성 유전자원과 염류 스트레스에 감수성 유전자원 간의 차이를 확인할 수 있는 엽록소형광 매개변수로 판단되며, 토마토 유전자원에 대해 염류 스트레스 수준을 평가할 수 있는 보완적인 도구로 활용 가능하다고 판단된다.

Cadmium (Cd) toxicity is a serious limitation for agricultural production. In this study, we explored tolerance mechanism associated with Cd toxicity tolerance in alfalfa plants. We used three distinct alfalfa cultivars M. sativa cv. Vernal, M. sativa cv. Zhung Mu, and M. sativa cv. Xing Jiang Daye in this study. Cd showed declined chlorophyll score in Xing Jiang Daye compared with Zhung Mu and Vernal. No significant change observed among the cultivars for root and shoot length. Atomic absorption spectroscopy analysis demonstrated a significant accumulation of Cd, Fe, S and PC in distinct alfalfa cultivars. However, Zhung Mu and Xing Jiang Daye declined Cd accumulation in root, where Fe, S and PC incremented only in Zhung Mu. It suggests that excess Cd in Zhung Mu possibly inhibited in root by the increased accumulation of Fe, S and PC. This was further confirmed by the response of Fe (MsIRT1) and S transporters (MsSULTR1;2 and MsSULTR1;3), and MsPCS1 genes associated with Fe, S and PC availability and translocation in roots and shoots. It suggests that specially the transcript signal inducing the responses to adjust Cd especially in Zhung Mu. This finding provides the essential background for further molecular breeding program for forage crops.
