Objectives: This study aims to understand the stress patterns and coping behaviors of women with infertility and to improve existing infertility stress assessment tools to develop a tool suited for Korean society. Methods: The study involved 10 women diagnosed with primary or secondary infertility. Data were collected through surveys and in-depth interviews. Participants were recruited voluntarily, and snowball sampling was used for additional recruitment. Data collection occurred from September 2023 to April 2024. Data analysis included Spearman's rank correlation, Mann-Whitney U test, and Kruskal-Wallis test. Interview results were analyzed using text mining and network analysis with Python 3.12. Results: There was a significant correlation between IVF/ICSI treatment and resilience scores, with non-IVF/ICSI groups showing higher resilience scores. Existing infertility stress assessment tools were generally useful but had limitations, such as discomfort with religious expressions and fixed gender roles, as well as issues with the number of items and response scales. Text mining of interview responses revealed key stress-related keywords including worry, depression, burden, pregnancy outcome, and health. Main stressors included uncertainty about pregnancy outcomes, physical discomfort during treatments, economic burdens, and emotional reactions from family and social relationships. Conclusions: This study identified the stress patterns of women with infertility through interviews. It showed the need for a new assessment tool to evaluate and support the complex stressors experienced by these women. Developing a comprehensive tool is essential for better understanding and managing the various stress factors faced by infertile women.

By delivering effective, in-situ conservation of biodiversity, OECMs can contribute to sustaining existing biodiversity values and improving biodiversity conservation outcomes. In this study, for the reporting of OECMs required by Kunming-Montreal Global Biodiversity Framework, the site-level assessment of the Korea National Arboretum and Buffer Zones were conducted using the assessment tool of IUCN. The site-level assessment was carried out in three steps(step 1: screening, step 2 : consent for full assessment, step 3 : the full assessment). It was found that the criteria were satisfied except for the consent for full assessment, sustainability of governance and management arrangements, and the equity of governance and management. Although the governing authority, rights-holders or any other stakeholders could be identified, the step of acknowledging and agreeing to the full OECM assessment was not possible because the governance was not established. As a result of the assessment of equitable governance and management in the aspect of recognition, procedure, and distribution based on criterion(the equity of governance and management), it is judged that more specific measures are needed in the aspect of recognition. And in the aspect of procedure, there is no legal basis for participation in governance and collection of opinions, so it is judged that there is a limit to listening and reflecting the opinions of stakeholders. In the aspect of distribution, it is necessary to further confirm whether it provides direct benefits to rights-holders such as landowners in the region. And it is necessary to prepare specific criteria to assess the important biodiversity values. Therefore, in order to promote OECM reporting in the future, it is necessary to conduct detailed research on various types of governance establishment and operation plans that can establish the basis for recognizing and agreeing to OECM assessment, specific criteria and reasonable measures to judge equity, and important biodiversity value.

As a part of probabilistic risk (or safety) assessment (PRA or PSA) of nuclear power plants (NPPs), the primary role of human reliability analysis (HRA) is to provide credible estimations of the human error probabilities (HEPs) of safety-critical tasks. In this regard, it is vital to provide credible HEPs based on firm technical underpinnings including (but not limited to): (1) how to collect HRA data from available sources of information, and (2) how to inform HRA practitioners with the collected HRA data. Because of these necessities, the U.S. Nuclear Regulatory Commission and the Korea Atomic Energy Research Institute independently developed two dedicated HRA data collection systems, SACADA (Scenario Authoring, Characterization, And Debriefing Application) and HuREX (Human Reliability data EXtraction), respectively. These systems provide unique frameworks that can be used to secure HRA data from full-scope training simulators of NPPs (i.e., simulator data). In order to investigate the applicability of these two systems, two papers have been prepared with distinct purposes. The first paper, entitled "SACADA and HuREX: Part 1. The Use of SACADA and HuREX Systems to Collect Human Reliability Data", deals with technical issues pertaining to the collection of HRA data. This second paper explains how the two systems are able to inform HRA practitioners. To this end, the process of estimating HEPs is demonstrated based on feed-and-bleed operations using HRA data from the two systems.

As a part of probabilistic risk (or safety) assessment (PRA or PSA) of nuclear power plants (NPPs), the primary role of human reliability analysis (HRA) is to provide credible estimations of the human error probabilities (HEPs) of safety-critical tasks. Accordingly, HRA community has emphasized the accumulation of HRA data to support HRA practitioners for many decades. To this end, it is critical to resolve practical problems including (but not limited to): (1) how to collect HRA data from available information sources, and (2) how to inform HRA practitioners with the collected HRA data. In this regard, the U.S. Nuclear Regulatory Commission (NRC) and Korea Atomic Energy Research Institute (KAERI) independently initiated two large projects to accumulate HRA data by using full-scale simulators (i.e., simulator data). In terms of resolving the first practical problem, the NRC and KAERI developed two dedicated HRA data collection systems, SACADA (Scenario Authoring, Characterization, And Debriefing Application) and HuREX (Human Reliability data EXtraction), respectively. In addition, to inform HRA practitioners, the NRC and KAERI proposed several ideas to extract useful information from simulator data. This paper is the first of two papers to discuss the technical underpinnings of the development of the SACADA and HuREX systems.

A simple and reliable cryo technique using desiccation and slow freezing of winter dormant buds was employed for 238 core collection of mulberry germplasm collected from diverse geographical regions and maintained under tropical conditions in the ex situ field gene bank to develop long-term biodiversity conservation for ensuring sustainable utilization of these valuable resources. Desiccation and freezing tolerance of bud grafts and excised shoot apices in the axillary buds of different Morus species under in vivo and in vitro condition indicated species-specific variation and most of the wild Morus species were found sensitive. In vitro regeneration and cryopreservation($-196^{\circ}C$) protocols using differentiated bud meristem like axillary winter dormant buds were worked out for a wide range of Morus species, land races, wild and cultivated varieties. Successful cryopreservation of mulberry winter dormant buds of different accessions belonging to M. indica, M. alba, M. latifolia, M. cathayana, M. laevigata, M. nigra, M. australis, M. bombycis, M. sinensis, M multicaulis and M. rotundiloba was achieved. Among wild species Morus tiliaefolia, and M. serrata showed moderate recovery after cryopreservation. Survival rates did not alter after three years of cryopreservation of different Morus species. ISSR markers were used to ascertain the genetic stability of cryopreserved mulberry, which showed no difference detected among the plantlets regenerated from frozen apices in comparison to the non-frozen material.

This study involved a total budget analysis on the greenhouse gas (GHGs) emissions of landfills, focusing on surface emissions and the effect on emissions reductions of generating landfill gas (LFG) electricity from March 7, 2007 to December 31, 2018. The GHGs reduction effect from the electricity generation using 536.6 × 10³ tCO₂ of CH₄ was only 5.8% of the GHGs from surface emissions of 9,191 × 10³ tCO₂. In the total budget, the collection ratio should be over 95% if the reduction effect is greater than the surface emissions. The correlation coefficient for the relationship between the LFG collection ratio and GHGs reduction was -0.89. An additional effect of lowering CH₄ content may occur if the surface emitting flux of LFG decreased with an increase in the collection ratio. The unit reduction effect of GHGs by suppressing surface emissions was 4174 tCO₂/TJ. This was far greater than that of LFG power generated (54.3 tCO₂/TJ), demonstrating that surface emission control is the most important measure by which to mitigate GHGs emission.

This study is understanding characteristics and analyzing contributions of the odor causing compounds of complex-odor & major specified odor materials, and contribution analysis, caused pre-treatment facilities(input and storage) and post-treatment facilities(heating and drying). The target of this study is feeds-production-facilities, located in Seoul. The averaged complex-odor compounds on the boundary line is 21 times higher, and it is 15 times higher than emission standards. In cracking&collection(pre-treatment facilities), the concentration of compounds is 4,881 times, 2,080 times in drying, and 1,442 times in putting&storing facilities. Ammonia occupies the largest portion of the results of monitoring specified odor compounds in input&storage facilities, followed Acetaldehyde > Hydrogen sulfide > Methyl mercaptan. In cracking&collection, Ammonia also occupies most of odor compounds, followed Methyl mercaptan > Acetaldehyde > Dimethyl disulfide > Dimethyl sulfide > Hydrogen sulfide. Acetaldehyde > Methyl mercaptan in drying facilities. On the boundary line, however, the concentration of specified odor compounds stays below emission standards. The result of contribution analysis is that methyl mercaptan has the highest contribution in input & storage, as well as cracking&collection facilities, followed Acetaldehyde > Hydrogen sulfide > Dimethyl sulfide > Dimethyl disulfide. In the drying facilities, the contribution shows Methyl mercaptan > Acetaldehyde > i-Valeraldehyde and Butyraldehyde. Therefore, to decrease odor in foodwaste treatment facilities, proper prevention facilities need to be installed and operated, according to characteristics of individual odor compounds, based on monitored data.

To have a better understanding of the impact of the PETRONAS oil and gas platform on commercial fisheries activities, Universiti Malaysia Terengganu (UMT) examined two approaches which are data collection from satellite and data collection from fishermen and anglers. By profiling the anglers who utilize reefed oil and gas structures for fishing, it can determine if the design and location of the reef platforms will benefit or negatively impacts those anglers and fisherman. Furthermore, this assessment will be contributing to the knowledge regarding the value of offshore oil and gas platforms as fisheries resources. Collectively, the apparent fishing activity data included, combined with the findings in the reefing viability index will help to inform PETRONAS's future decommissioning decisions and may help determine if the design and proposed locations for future rigs-to-reefs candidates would benefit commercial fishing groups, further qualifying them as appropriate artificial reef candidates. The method applied in this study is approaching by using a data satellite known as Google's Global Fishing Watch technology, which is one of the applications to measure commercial fishing efforts around the globe. The apparent commercial fishing effort around the selected twelve PETRONAS platforms was analyzed from January 2012 to December 2018. Using the data collection from fishermen which is the total estimation of commercial fish value cost (in Malaysia ringgit, MYR [RM]) in Peninsular Malaysia Asset, Sabah Asset, and Sarawak Operation region. The data were extracted every month from 2016 to 2018 from the National Oceanic and Atmospheric Administration database. Most of the selected platforms that show a high frequency of vessels around the year are platform KP-A, platform BG-A and platform PL-B. The estimated values of commercial fishes varied between platforms, with ranged from RM 10,209.92 to RM 89,023.78. Thus, platforms with high commercial fish value are selected for reefing in-situ and will serve multi-purposes and benefit the locals as well as the country. The current study has successfully assessed the potential reefing area of the Malaysian offshore environment with greater representativeness and this paper focused on its potential as a new fishing ground.
