Affinity Selection Mass Spectrometry (AS-MS) as a Tool for Prospecting Target Ligands
Authors: Almeida Fernando , Cass Quezia
Published: March 2023

Affinity selection mass spectrometry (AS-MS) has been shown to be a powerful tool for identifying bioactive molecules in synthetic and/or natural libraries. The selection provided by the formation of the target-ligand complex allows the identification of hits irrespective of their functional effect. Moreover, it precludes the use of label, since the binders are identified by their exact mass.1 The binders are determined by an affinity or index ratio calculated through control assays. The target protein can be used in solution or immobilized in a solid support (Figure 1). Both approaches have pros and cons. Unlike most conventional high-throughput screening assays, AS-MS has fewer or no limitations when it comes to target selection. It is important, however, to understand the implications of choosing membrane proteins as targets. Membrane proteins correspond to 42% of all drug targets listed in DrugBank. Moreover, they are likely to be selected as protein targets due to their participation in many disease pathways, acting as ion channels, molecular transporters, solute carriers, receptors, and anchors. One of the bottlenecks in working with membrane proteins comes from the need to use a detergent for solubilization, folding, and structure maintenance. Detergents are usually used above the critical micelle concentration, which can lead to empty micelles and thus to false positive results, caused by nonspecific interactions with the detergent micelles.8 Interference in the ionization of the binders also needs to be examined.
Balance between Public Interest and Private Interest in Land Compensation
Authors:   Korean Public Land Law Association, Min Tae-Wook
Published: March 2023

In expropriation of land, there is a conflict between public interest and private interest. Public interest request land expropriation, but it deprive ownership from private owner. It is unreasonable to give priority only one party, so reasonable balance is need between the two interests. With this point in view, the Constitution request ‘public needs’ to expropriate land and ‘just compensation’ to private owner. The main purpose of land expropriation is to pursue public interest. The modern state which act in wide-ranging area for people can expropriate land extendedly. Even law permit for private housing developer to expropriate land. In this case, the balance between public interest - private interest of developer - private interest of land owner are out of proportion, and there is no legal device to use the profits which derived from land expropriation continuously for public needs. So giving land expropriation power to private housing developer is required further examination. ‘Just compensation’ are composed ‘justified price compensation’ and ‘exclusion of development gains’. ‘Justified price compensation’ which means ‘compensation by market value’ is properly observed. Though Land Compensation Act prescribe that land is compensated by Standard Public Land Price, actually land is compensated by market sales price. On the other hand, ‘exclusion of development gains’ is not observed properly, it is influenced by appraiser’s discretion, because regal device is inadequate and public implementer is passive in control. So it is desirable that change legal standard of compensation from Standard Public Land Price to market value. And appraiser recommendation of owner and administrative agent system are in need of reform.

Authors:   Korean Public Land Law Association, Kyen Seung Yup
Published: March 2023

The Framework Act On the Management Of Disasters And Safety enacted and implemented in 2004 integrated Natural Disasters and Social Accidents into disasters, established a systematic and effective disaster management and safety management system for all social factors that can damage people's lives, bodies, property, and the State. However, despite the steady improvement of the disaster and safety management system, disasters in our society continue to occur. The Framework Act On The Management Of Disasters And Safety, which consisted of 81 articles at the time of enactment, increased to 149 articles as of 2022, and more than 40 revised legislation on disaster management administration such as organization, planning, and authority, but It happened a disaster massive casualties in the Itaewon on October 29, 2022. The 21st National Assembly also supplemented the Framework Act On The Management Of Disasters And Safety after the disaster, but the law is already complicated and difficult to understand due to frequent revisions, impeding the predictability of the law and making it difficult to achieve The Rule of Law Principle in Korean administrative law. In addition, It is necessary to establish relations between individual laws such as already enacted the Disaster Safety Communication Network Act and the Disaster Safety Industry Promotion and such as discussing the Framework Act on Safety and the Disaster Management Resources Act. Therefore, this study aims to secure public safety rights by analyzing problems in terms of the Framework Act On The Management Of Disasters And Safety and the system of related laws, securing predictability of laws, and proposing a plan to re-establish the Framework Act On The Management Of Disasters And Safety.
The necessity of enacting independent legislation reflecting the entire life cycle of drones
Authors:   Korean Public Land Law Association, Yang Eun Young
Published: March 2023

It is no exaggeration to say that drones are the leader of the Fourth Industrial Revolution, and the whole world is paying attention to fostering the drone industry. Since drones reflect the verification of state-of-the-art technology and the improved emotional culture of humans, Korea's drone law is currently focusing on the use of drones, industrial development, fostering, and promotion, so it is necessary to strengthen regulations on risks and side effects from the expansion of the drone industry. Korea deals with regulations on the production, ownership, and operation of drones, focusing on the Aviation Safety Act, which is largely applied differently depending on weight and business status. Unlike Korea, aviation-related laws such as drone reporting, pilot certification, flight airspace, and pilot compliance are organized into separate chapters or enacted separate laws in major advanced aviation countries, while Korea's drone-related laws are scattered in many related laws, so there are many problems in practical application. Most basically, even the terms established in the law are not unified in practice, the standards presented in practice are not reflected in the law, and accordingly, there is a gap between laws and practice in safety management standards and operation. The Ministry of Land, Infrastructure and Transport has come up with measures to strengthen some regulations to improve the safety of drones, but the problem is that legislative omission and simple formal regulations are being made due to inadequate regulations on aircraft declaration, safety certification and flight approval, and pilot certification systems and excessive deregulation. In addition, public law regulation is urgent in that there is no control means for drones in operation, there are limitations in cracking down on drones in illegal flight, and there is no instructions for the disposal of drones that have been operated. Therefore, in this study, the existing laws and regulations focusing on the stages of the drone's entire life cycle, it is applied at each stage are combined to improve measures such as supplementing legislative inadequacies, for example, clarification of drone definition, legislation of liability insurance, strengthening safety security regulations, practical drone crackdown and production requirements, drone disposal, etc. and to make it easier for the people subject to the law to understand, I will propose a direction to preemptively prepare legislation that deals only with drones to improve the current drone-related legislation, which is stipulated in conjunction with existing aircraft, to form a separate chapter in the Aviation Safety Act, or to enact a new individual law, considering the infinite growth potential of the drone industry and its influence on society.

Authors:   Korean Public Land Law Association, Cho Pilkyu
Published: March 2023

This study analyzed the current status and characteristics of Seoul's improvement projects and especially the current status and cases of implementation of ‘Rapid Integrated Planning’ for the purpose of deriving institutional improvements and presenting policy directions for the vitalization of ‘Rapid Integrated Planning’. As a result of the study, the following conclusions were obtained. First, about 25,000 housing units will be supplied in Seoul through the introduction of ‘Rapid Integrated Planning’. Second, 21 ‘private redevelopment candidate sites’ were selected in the first phase of the ‘Rapid Integrated Planning’, but it took a little longer than expected by the Seoul Metropolitan Government. Third, the ‘Rapid Integrated Planning’ is promoted mainly for redevelopment project, and the participation in reconstruction project is withheld or withdrawn due to rental housing, etc. Fourth, in areas where ‘Rapid Integrated Planning’ was selected, it became possible to select a construction company after the establishment of the association. Fifth, it is necessary to improve the evaluation index reflecting the various characteristics of the target area. As described above, in order to achieve the policy goal of ‘Rapid Integrated Planning’, it is necessary to target areas in the blind spot of the improvement projects due to declining business feasibility and conflicts with residents. In addition, efforts to discover and promote institutional improvement and support systems from the perspective of residents should be supported.
Japanese Parliamentary Diplomacy on the Eve of the Cold War: Focusing on the Taiwan Channel
Authors: Natsuko Miyokawa
Published: March 2023

This study explores the diplomacy of the conservative ruling party lawmakers in Japan toward Asia on the eve of the Cold War. It shows— based on interviews and latest archival material released in Japan and Taiwan—that a structure for ending the Cold War existed in East Asia on the eve of the Cold War, which is different from the Second Cold War framework centered on the West. This research may also play a significant role in the study of the long-term governments of conservative parties and their foreign policies during the Cold War. Before the Cold War was over, the governments of Nakasone Yasuhiro and Takeshita Noboru in Japan had access to both China and Taiwan, and there were already movements within the conservative ruling Liberal Democratic Party and its factions toward a de-Cold War structure and ideology. Pro-Taiwan and pro-Korea factions in the party, which had overlapped since the formulation of the Cold War ideology, diverged. In this context, despite the timely utilization of personal relations between Taiwan and Japan since the prewar Japanese colonial period, an effective systematization of channels between the two governments that could be sustained over the long-term was not achieved.

Authors: Fajar Rohmawati Depita , Mukti Wibowo Yari
Published: March 2023

Fresh milk is a liquid produced by healthy and clean animals, such as cows. The natural content of fresh milk is not reduced or added by other compounds and is only treated with a cooling process without affecting its purity. Fresh milk can be contaminated with lead metal (Pb), because animal feed or water has been contaminated with Pb. If we consume fresh cow's milk in the long term, it can interfere with health. According to SNI 3141.1: 2011, the maximum Pb level allowed in fresh cow's milk is 0.02 µg / mL. It is necessary to test fresh cow's milk, one of which is to determine the Pb level, so that the fresh cow's milk is suitable for consumption. Pb levels were determined by Atomic Absorption Spectrophotometer (AAS) based on SNI 01-2896-1998. The Pb content in the fresh cow's milk sample was determined by wet digestion and then analyzed by AAS at 283.3 nm lamda. The results showed that the Pb levels were 0.0570 µg / mL (sample A), 0.1230 µg / mL (sample B) and 0.0380 µg / mL (sample C). From these results it can be seen that the Pb content in the fresh cow milk sample does not meet the requirements based on SNI 3141.1: 2011.

Review: The Transformation Of The Meaning Of Kebaya From National Clothing To A Media Of Self-Representation And Lifestyle
Authors: Kusumadewi Putu Diah Ari , Jerusalem Mohammad Adam
Published: March 2023

As a cultural product of the Indonesians, Kebaya has become a national dress that sticks with its philosophical principles and values. However, along with the times and the influence of popular culture, the kebaya changed its design lines. It caused a transformation of the meaning of the Indonesian national dress into a medium of self-representation and the lifestyle of modern women. This review aims to analyze the transformation of the meaning of kebaya as a medium of self-representation and lifestyle. The method used is a narrative review by analyzing several articles using the PRISMA method. The analysis results show that the kebaya, as Indonesia's national dress, has design characteristics, materials, and accessories that contain philosophical meanings that reflect the personality of Indonesian women. The design transformation of the traditional kebaya gave birth to a modern kebaya far from the standard of the conventional kebaya. Modern kebaya is interpreted as a symbol representing the wearer's self-image and social class. The modern kebaya, as a medium of self-image and social class, gives birth to a new lifestyle in society, namely a consumptive lifestyle, because someone will carry out consumption activities continuously without considering the use value of the item. Besides being able to complete references related to kebaya, the results of this review are also expected to be input for related parties to maintain the traditional kebaya standard and consider ethics in buying kebaya so as not to create a consumptive lifestyle.

Published: March 2023

Covid-19 has tremendously impacted global daily life and the built environment, particularly in tourist places' pleasure. Modern architectural practices, such as planning tourist sites, must display new patterns while updating current ones to control contagious diseases efficiently. Polarity is a spiritual concept in Bali that focuses on the impact of nature and geography on traditional Balinese societies. The island's natural environment influences traditional Balinese beliefs and practices on the propriety of specific architectural types and space layouts. According to this theory, the universe was created by colliding two opposed poles. It makes some suggestions for improving the layout of rural villages. This architecture can be seen on the Indonesian island of Bali at several major tourist spots, most notably in the island's eastern area. Despite this, the Covid-19 pandemic underscored the significance of virus prevention in building design, particularly tourist-oriented hotels. Architects, designers, environmentalists, and others in the tourism industry face several challenges while creating and building environmentally sustainable tourist facilities. The study's goal was to see if the traditional architectural principles of eastern Bali could be leveraged to create a tourism facility template that would allow the hospitality industry to meet the demand for new, effective layouts and layout variants. As a result, the villages in eastern Bali that have preserved their old practices have contributed significantly to our understanding of what it means to be a modern human. Professionals can use historical knowledge to build resilient patterns and configurations even when confronted with modern threats, such as viral attacks on famous tourist locations. This study refuted several long-held ideas in light of the Covid -19 results.

Differential expression of TRIB3 in colorectal cancer.
Authors: Mamoor Shahan
Published: March 2023

Cancer is a leading cause of death and colorectal cancer is among the most lethal cancers (1, 2). We mined public and published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with colorectal cancer (CRC). We found significant differential expression of the gene encoding tribbles pseudokinase 3, TRIB3, when comparing colorectal tumors to the tissue of origin, the colon. TRIB3 mRNA was present at significantly higher quantities in tumors of the colon as compared to normal colorectal tissue. TRIB3 expression changes may be important for the initiation or progression of human CRC.

Cancer is a leading cause of death and colorectal cancer is among the most lethal cancers (1, 2). We mined public and published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with colorectal cancer (CRC). We found significant differential expression of the gene encoding ETS variant 4, ETV4, when comparing colorectal tumors to the tissue of origin, the colon. ETV4 mRNA was present at significantly higher quantities in tumors of the colon as compared to normal colorectal tissue. Analysis of human survival data revealed that expression of ETV4 in rectal tumors was correlated with overall survival in patients with rectal cancer; the direction of this correlation was apparently dependent on macrophage tumor infiltration status. ETV4 expression changes may be important for the initiation or progression of human CRC.
Energy Efficiency Policies in Malaysia: A Critical Evaluation from the Sustainable Development Perspective
Authors: Aktar Asikha , Alam Md. Mahmudul , Harun Mukaramah
Published: March 2023

Reduced electricity demand through the implementation of an energy efficiency policy is a central pillar of the Malaysian government’s energy strategy. Energy efficiency first emerged as part of Malaysia’s energy policy agenda in 1979 but only came into force during the 2000s. Initially, it was seen from global fears about the shortage of fossil fuels, then as a way of combating climate change. This paper offers a comprehensive review of Malaysia’s energy policies with a focus on adopting policies to improve energy efficiency. Starting with Malaysia’s preliminary policy in response to the OPEC-driven global oil crisis in 1973, the paper discusses how policymakers are considering energy efficiency from Malaysia’s sustainable development perspective and what relevant government efforts have been made to improve it. The review evaluates the progress that has been made over the past 25 years to address energy efficiency in the economy and highlights the achievements and remaining difficulties. Findings show that the level of energy efficiency while having shown improvement during 1990-2015, was lower than expected. In terms of electricity intensity of GDP, Malaysia has a relatively large position among the ASEAN countries and the world’s largest electricity consumers. Researchers, scientists, and practitioners will benefit from the extensive review material of this study, which will help them better understand energy efficiency and the sustainability strategy implemented in Malaysia to date.
Differential expression of CSE1L (XPO2) in colorectal cancer.
Authors: Mamoor Shahan
Published: March 2023

Cancer is a leading cause of death and colorectal cancer is among the most lethal cancers (1, 2). We mined public and published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with colorectal cancer (CRC). We found significant differential expression of the gene encoding chromosome segregation 1-like, CSE1L, also known as exportin 2 (XPO2), when comparing colorectal tumors to the tissue of origin, the colon. CSE1L mRNA was present at significantly higher quantities in tumors of the colon as compared to normal colorectal tissue. Analysis of human survival data revealed that expression of CSE1L in rectal tumors was correlated with overall survival in patients with rectal cancer with high mutational burden. We recently demonstrated that another molecule with central functions in nuclear transport, karyopherin alpha 2 (also known as importin alpha 1) is also among the genes whose expression is most significantly different, transcriptome-wide, in tumors of the colon from patients with colorectal cancer (5). CSE1L/XPO2 expression changes, perhaps functioning in concert with changes in KPNA2 expression, may be important for the initiation or progression of human CRC.
A Novel Heuristic Method for Detecting Overfit in Unsupervised Classification of Climate Model Data
Authors: Boland Emma , Atkinson Erin , Jones Dan
Published: March 2023

Unsupervised classification is becoming an increasingly common method to objectively identify coherent structures within both observed and modelled climate data. However, in most applications using this method, the user must choose the number of classes into which the data are to be sorted in advance. Typically, a combination of statistical methods and expertise is used to choose the appropriate number of classes for a given study, however it may not be possible to identify a single `optimal' number of classes. In this work, we present a heuristic method, the Ensemble Difference Criterion, for unambiguously determining the maximum number of classes supported by model data ensembles. This method requires robustness in the class definition between simulated ensembles of the system of interest. For demonstration, we apply this to the clustering of Southern Ocean potential temperatures in a CMIP6 climate model, and show that the data supports between four and seven classes of a Gaussian Mixture Model.
Evaluating methane emission quantification performance and uncertainty of aerial technologies via high-volume single-blind controlled releases
Authors: Rutherford Jeffrey , Sherwin Evan , Chen Yuanlei , Aminfard Sam , Brandt Adam
Published: March 2023

Methane (CH4) from oil and gas (O&G) activities is a known contributor to global anthropogenic methane emissions and recent research has demonstrated that a small fraction of large emitters contribute to the majority of total emissions. In this study, we perform a single-blind evaluation of the quantification capabilities of three airplane-based technologies (Bridger Photonics’ Gas Mapping LiDAR, Carbon Mapper’s Global Airborne Observatory, and GHGSat-AV) with a focus on large emitters (10-2,000+ kg h-1 CH4). In two 2021 campaigns, metered natural gas was released concurrently with overpasses by the tested technologies. Results were submitted by operators in a three-stage unblinding process. All teams detected 100% of releases above 50 kg h-1 CH4. The teams report parity slopes of 0.35 to 1.06, with R2 values of 0.35 to 0.78. After 10-meter anemometer wind measurements were unblinded, two out of three teams significantly reduced variance in the parity slope, highlighting the importance of accurate wind data. After half of metered release volumes were subsequently unblinded, improvement was mixed. These results suggest that multiple commercially available technologies can reliably detect larger point-source methane emissions, with varying quantification performance and trade-offs between survey area coverage and instrument sensitivity.
Within-Person Personality Variability in the Work Context: A Blessing or a Curse for Job Performance?
Authors: Abrahams Loes , Vergauwe Jasmine , De Fruyt Filip
Published: March 2023

Only recently, the question whether within-person personality variability is a blessing or a curse for job performance has reached the agendas of Industrial and Organizational (I-O) psychology researchers. Yet, this limited stream of research resulted in inconsistent findings, and only little understanding exists about the role of rater source and mean-level personality in this relationship. Broadly following socioanalytic theory, the present study examined the extent to which self- and other-rated within-person personality variability predict self- and other-rated job performance, and whether this is moderated by mean-level personality. Within-person personality variability indices and job performance evaluations were obtained from an experience sampling study including N = 166 teachers, N = 95 supervisors, and N = 69 classes (including 1,354 students). Results showed that—above and beyond the effects of mean-level personality—self-rated within-person variability was positively associated with self-rated job performance, while other-rated within-person variability was negatively associated with other-ratings of performance. Many interactions with mean-level personality were found, mainly demonstrating negative effects of variability for those with a less adaptive personality profile (cf. variability as a ‘curse’), while showing positive effects of variability for those with a more adaptive trait profile (cf. variability as a ‘blessing’). Importantly, however, additional analyses provided little evidence for associations across type of rater source. These findings contribute to the field of I-O psychology by highlighting that perceptions of within-person personality variability may impact performance evaluations beyond personality traits, although its desirability seems to depend on individuals’ personality trait level. Implications and limitations are discussed.

Beyond the RewP: The reward feedback-elicited LPP and its potential associations with perceived stress and internalizing symptoms in late childhood
Authors: Tan Jaron Xe Yung , Liu Pan
Published: March 2023

Internalizing problems increase substantially during late childhood and early adolescence, which are known to be associated with elevated perceived stress as children transition into adolescence. One risk factor that may moderate the stress-symptom association is reward processing. While neurophysiological research in this field has focused on the reward positivity component (RewP) elicited during reward processing, little work has examined the reward feedback-elicited late positive potential (LPP) and its association with internalizing psychopathology. The present study examined the moderating roles of the RewP and feedback-elicited LPP in the relationship between perceived stress and internalizing symptoms in late childhood. A community sample of 115 nine-to-12-year-old children (66 girls, Mean age = 11.00 years, SD = 1.16) completed an EEG version of the reward feedback paradigm, the Doors task, and completed questionnaires on perceived stress and internalizing symptoms. A principal component analysis revealed three temporo-spatial factors that were temporally and spatially analogous to the RewP, anterior LPP, and posterior LPP, respectively. As expected, an enlarged RewP was found towards the win condition compared to the loss condition. We also observed a potentiated LPP towards loss relative to win feedback, which may reflect the evaluation and reappraisal processes following unsuccessful performance (i.e., loss). We did not, however, find significant moderating effects of any ERP components on the stress-symptom association. Our study was first to isolate the feedback-elicited LPP in a reward processing paradigm in children and provide initial evidence on the modulation of the ERP component by task conditions. Future research is warranted to further explore the functional significance of the reward feedback-elicited LPP in association with perceived stress and internalizing psychopathology in youths.
