Since Korean Seamen Act(herein after called "the Act") has been legislated in 1962, an amendment of the Act has duly performed several times in order to meet an essential guideline of appropriate international convention and practical requirement of domestic labour movement. As the Act in many area, is based on the application of international convention and regulations, it has been considered essential to call attention to such international rules, to emphasize their importance, and to indicate how and to what extent they may be incorporated in national law, in accordance with national constitutional rules and requirements. Of newly amended act in 1991, it could, however, not fully reflect an adequate and modern labour standard as a guideline of the convention. Therefore, a principal objective of this paper is to provide a comprehensive reference work to assist amending up-to-data seamen act against the Act. The guidelines, however, do not attempt to suggest or formulate a legislative programme, but rather provide an ordered and specific content corresponding to international convention adopted by ILO. Consequentially, these guidelines aim to direct the reader and legislator toward the sources and contents of what has come to constitute an international code of maritime labour standards. The guidelines described herein may also serve as a specific arrangement to the various kinds of legal aspects to be regulated through reasonable future amendment under amicable agreement between interesting parties.g parties.

Phytophthora diseases have become a major impediment in the citrus production in Thailand. In this study, an isolate of Phytophthora denominated as PHY02 was proven to be causal pathogen of root rot of Pomelo (Citrus maxima) in Thailand. The isolate PHY02 was morphologically characterized and identified as Phytophthora palmivora based on molecular analysis of an internal transcribed spacer rDNA sequence. This work also presents in vitro evaluations of the capacities of Chaetomium spp. to control the P. palmivora PHY02. As antagonists, Chaetomium globosum CG05, Chaetomium cupreum CC3003, Chaetomium lucknowense CL01 inhibited 50~61% mycelial growth, degraded mycelia and reduced 92~99% sporangial production of P. palmivora PHY02 in bi-culture test after 30 days. Fungal metabolites from Chaetomium spp. were tested against PHY02. Results showed that, methanol extract of C. globosum CG05 expressed strongest inhibitory effects on mycelial growth and sporangium formation of P. palmivora PHY02 with effective dose ED50 values of $26.5{\mu}g/mL$ and $2.3{\mu}g/mL$, respectively. It is interesting that C. lucknowense is reported for the first time as an effective antagonist against a species of Phytophthora.

The phase field model is becoming the model of choice for the theoretical study of the morphologies of crystals growth from the melt. This model provides an alternative approach to the solution of the classical (sharp interface) model of solidification by introducing a new variable, the phase field, Ø, to identify the phase. The variable Ø takes on constant values in the bulk phases and makes a continuous transition between these values over a thin transition layer that plays the role of the classically sharp interface. This results in Ø being governed by a new partial differential equation(in addition to the PDE's that govern the classical fields, such as temperature and composition) that guarantees (in the asymptotic limit of a suitably thin transition layer) that the appropriate boundary conditions at the crystal-melt interface are satisfied. Thus, one can proceed to solve coupled PDE's without the necessity of explicitly tracking the interface (free boundary) that would be necessary to solve the classical (sharp interface) model. Recent advances in supercomputing and algorithms now enable generation of interesting and valuable results that display most of the fundamental solidification phenomena and processes that are observed experimentally. These include morphological instability, solute trapping, cellular growth, dendritic growth (with anisotropic sidebranching, tip splitting, and coupling to periodic forcing), coarsening, recalescence, eutectic growth, faceting, and texture development. This talk will focus on the fundamental basis of the phase field model in terms of irreversible thermodynamics as well as it computational limitations and prognosis for future improvement.

Korea Astronomy and Space Science Institute We present a weak-lensing study of the galaxy cluster SPT-CL J2106-5844 at z=1.132 discovered in the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) survey. The cluster is claimed to be the most massive system at z > 1 in the SPT-SZ survey. The inferred mass ($M_{200c}=(1.27{\pm}0.21){\times}10^{15}M_{sun}$) is somewhat unusual at such a high redshift given the current ΛCDM prediction. The mass estimates, however, may be biased because the hydrostatic assumption may not hold when the universe was about 40% of the current age. In this work, we reconstruct the dark matter distribution and measure the mass of this interesting cluster using weak-lensing analysis based on the images from the Advanced Camera for Surveys and Wide Field Camera 3 on-board the Hubble Space Telescope. We find that the mass distribution of the cluster is unimodal with no significant substructures. The centroid of the dark matter agrees with both galaxy luminosity and number density distributions, as well as the hot gas centroid. We confirm that the cluster is indeed extremely massive ($M_{200c}=(1.81{\pm}0.47){\times}10^{15}M_{sun}$) supporting the previous non-lensing measurements. We also discuss the rarity of the cluster in the ΛCDM cosmology, comparing with the expected abundance of similarly massive clusters.

Protein kinase C theta (PKC-${\theta}$) is a serine/threonine specific protein kinase. It is largely expressed in the T-cells and CD28 signaling. PKC-${\theta}$ phosphorylates diverse proteins that are involved in the various cellular signaling pathways. Activated PKC-${\theta}$ in turn activates other transcription factors that control the proliferation and differentiation of T- cells. PKC-${\theta}$ is considered to be an interesting therapeutic target due to its crucial role in the proliferation, differentiation and survival of T-cells. In the present study, we have performed ligand-based CoMFA study on a series of pyridylpyrazolopyridine derivatives as PKC-${\theta}$ inhibitors. An acceptable CoMFA model ($q^2$=0.544; ONC=4; $r^2$=0.876) was developed and validated by Bootsrapping and progressive sampling. The CoMFA contour map suggested the regions to increase the activity. Bulky substitutions in R2 position of the piperizine ring could increase the activity. Similarly positive, small substitution in the R1 position of the Pyridine ring could considerably increase the activity. Our work could assist in designing more potent PKC-${\theta}$ inhibitors of pyridylpyrazolopyridine derivatives.

Modern design of long suspension bridges must satisfy at the same time spanning very long distances and limiting their response against several external loads, even if of high intensity. Structural Control, with the solutions it provides, can offer a reliable contribution to limit internal forces and deformations in structural elements when extreme events occur. This positive aspect is very interesting when the dimensions of the structure are large. Herein, an updated numerical model of an existing suspension bridge is developed in a commercial finite element work frame, starting from original data. This model is used to reevaluate an optimization procedure for a passive control strategy, already proven effective with a simplified model of the buffeting wind forces. Such optimization procedure, previously implemented with a quasi-steady model of the buffeting excitation, is here reevaluated adopting a more refined version of the wind-structure interaction forces in which wind actions are applied on the towers and the cables considering drag forces only. For the deck a more refined formulation, based on the use of indicial functions, is adopted to reflect coupling with the bridge orientation and motion. It is shown that there is no variation of the previously identified optimal passive configuration.

This paper presents the work of Southeast Asian scholar Ramon Guillermo. Using sophisticated computer-aided methods, Guillermo approaches a range of topics in the wide fields of social sciences and the humanities. A creative writer as well as an activist, Guillermo grounds his studies in nationalism and Marxism. Particularly interested in Indonesian and Philippine society and culture, Guillermo engages with the writings of labor leaders Tan Malaka and Lope K. Santos, translations of Marx's Capital into Bahasa and Filipino, and studies as well the discursive and historical connections between the Communist Parties of both countries. The paper aims to introduce the innovations of Guillermo's studies, particularly in the fields of cultural studies and translation studies. The type of cultural studies Guillermo practices is empirical, taking inspiration from innovations done in the digital humanities. Guillermo is most opposed to trendy, fashion-seeking approaches that are not grounded on history. He reserves particular ire for "hip" postcolonialism, and instead praises studies that are founded on politics and materialism. In translation studies, Guillermo goes beyond the mere cataloguing of mistakes. For him, it is the mistakes and "perversities" of a translation that is interesting and illuminating. Guillermo himself is a translator, and the paper ends with a brief discussion of his production in this field.

In order to examine the cultural vicious cycle of gender representation in online educational content, this paper reviewed the top five popular webtoons of inamootoon (EBStoon), Korea's first children's webtoon platform. The patterns of appearance representation that distinguish character's gender, the desire and psychology of characters according to gender, and their functions in the work were critically analyzed from a feminist perspective. In most of the works, the appearance of characters often follows gender stereotypes. It appears that women have long hair and wear dresses while men have short hair. On the other hand, the gender characteristics in terms of psychology and function show the aspect of breaking gender's cliche. The gender proportion of the protagonists is almost the same. Regardless of gender, they function as solvers or rescuers, bravely and wisely overcoming the problem situation. By the way, it is interesting that in representing the main character's gender, the weaker the gender stereotypes, the more popular the work among the readers. This fact suggests that the critical acceptance and choice of young readers can break the cultural vicious cycle of gender representation.
