Canonical idioms are in general syntactically opaque and semantically non-compositional. However, there also exist many idioms whose component parts are rather morpho-syntactically transparent and semantically decomposable. This paper identifies two types of Korean idioms and review their basic properties. Based on these empirical studies, the paper then proposes a constraint-based approach that can allow us to process these two different types of idioms.

In this paper, we propose an efficient freedom of information and Information access right which improves transparent and speedy administration process. To build open Information, we scrutinize that causes of non access right and change of civil service consciousness, attitude for open information by effectively open system circumstances. The Important thing is basic information that is available to the public through an agency's FOIA Reference Guide, all agencies must notify potential FOIA requesters of the formal rules and requirements for the making and handling of FOIA request, through their FOIA regulations. The characteristics of this paper focused on Information access right, causes of non access right and proposed policy. In this paper, The author emphasize are as follows: first, to examine freedom of information' necessity and problem that scrutinize a theoretic analysis, second, to understand civil servant's attitude for the freedom of information, third, to suggest action plan and agenda for the better of Good Governance and Democracy of information.

Haematococcus pluvialis is a commercial microalga that can produce high quantities of astaxanthin. Under induced conditions, some important changes in the subcellular structures related to astaxanthin accumulation were observable. For example, a large number of astaxanthin granules, oil structures and starch granules appeared in the thick-walled cells; Astaxanthin granules gradually dissolved into the oil structures and spread throughout the entire cell with the fusion and diffusion process of oil structures during the middle and late stages of induction; The plastoglobules were closed to the newly formed structures, and some plastoglobules would abnormally increase in size under stress. Based on observations of cell damage, the degradation of membrane structures, such as chloroplasts, was found to be the primary form of damage during the early stage of induction. During the middle stage of induction, some transparent holes were exposed in the dissolving astaxanthin granules in the cytoplasm. In thick-walled cells, these transparent holes were covered by oil substances dissolving astaxanthin, thereby avoiding further damage to cells. Given the relatively few oil structures, in non-thick-walled cells, the transparent holes expanded to form multiple transparent areas, eventually resulting in the rupture and death of cells. These results suggested that the high level of synthesis and the wide range diffusion of oil explained the expansion of astaxanthin in H. pluvialis.

Detailed flame structures of the counterflow flames of $CH_4/Air$ formed with $CO_2$ and $H_2O$ addition are studied numerically. The detailed chemical reactions are modeled by using the OPPDIF and CHEMKIN-II code. Only the $CO_2$ and $H_2O$ are assumed to participate in radiative heat transfer while all other gases are assumed to be transparent. The discrete ordinates method(DOM) and the narrow band based WSGGM with a gray gas regrouping technique(WSGGM-RG) are applied for modeling the radiative transfer through non-homogeneous and non-isothermal combustion gas mixtures generated by the counter flow flames. The results compared with the SNB model show that the WSGGM-RG is successful in modeling the counterflow flames with non-gray gas mixture. The numerical results show that the addition of $CO_2$ and $H_2O$ to the oxidant nozzle lowers the peak temperature and the NO concentration in flame.

Scanning acoustic microscopy (SAM) or Acoustic Micro Imaging (AMI) is a powerful, non-destructive technique that can detect hidden defects in elastic and biological samples as well as non-transparent hard materials. By monitoring the internal features of a sample in three-dimensional integration, this technique can efficiently find physical defects such as cracks, voids, and delamination with high sensitivity. In recent years, advanced techniques such as ultrasound impedance microscopy, ultrasound speed microscopy, and scanning acoustic gigahertz microscopy have been developed for applications in industries and in the medical field to provide additional information on the internal stress, viscoelastic, and anisotropic, or nonlinear properties. X-ray, magnetic resonance, and infrared techniques are the other competitive and widely used methods. However, they have their own advantages and limitations owing to their inherent properties such as different light sources and sensors. This paper provides an overview of the principle of SAM and presents a few results to demonstrate the applications of modern acoustic imaging technology. A variety of inspection modes, such as vertical, horizontal, and diagonal cross-sections have been presented by employing the focus pathway and image reconstruction algorithm. Images have been reconstructed from the reflected echoes resulting from the change in the acoustic impedance at the interface of the material layers or defects. The results described in this paper indicate that the novel acoustic technology can expand the scope of SAM as a versatile diagnostic tool requiring less time and having a high efficiency.

The objective of this paper is to examine the legal framework governing the import and export of grain in China, a pivotal factor in shaping policies aimed at stabilizing South Korea's foreign trade and grain imports. Through this analysis, it is observed that China's foreign trade system, governed by the Foreign Trade Act, exhibits a notable absence of clear delineation regarding the scope and responsibility for the delegation of authority to foreign trade management agencies. In contrast, Korea's Foreign Trade Law, along with its enforcement decree and management regulations, explicitly outlines the scope and responsibilities pertaining to the delegation of authority to foreign trade management. However, in the case of China's revised Foreign Trade Law, there exists a lack of precision in specifying the delegation of authority to foreign trade management. This creates a potential for discretionary intervention by local governments or other administrative bodies. While China's legal system concerning grain imports and exports aligns with WTO regulations in its institutional framework, attention is warranted due to the vagueness in laws or regulations, as well as the presence of irrational and non-transparent procedures during system operation. As conclusion remarks, while China's legal structure related to grain imports and exports conforms to WTO guidelines overall, the identified issues such as legal ambiguity and non-transparent procedures underscore the need for caution. To safeguard against potential challenges in future trade interactions with China, proactive measures are crucial to address these concerns.

Shear behavior of granular soils largely affects the safety and stability of underground and earth structures. This study presents the characteristics of shear zone in a direct shear test using shear wave and electrical resistivity measurements. An innovative direct shear box made of transparent acrylic material has been developed to prevent direct electric current. Bender elements and electrical resistivity probe are embedded in the wall of direct shear box to estimate the shear wave velocities and the electrical resistivity at the shear and non-shear zones. Experimental results show that the void ratio and shear wave velocity at shear zone increase during shearing while the values remain constant at non-shear zone. The results demonstrate correlation among the contact force, small strain shear modulus, and void ratio at shear zone. This study suggests that the application of the modified direct shear box including shear wave and electrical resistivity measurements may become an effective tool for analyzing soil behavior at shear zone.

The structures of the fertilized egg envelope in three species of cichlidae, golden severum (Cichlasoma severum var.), convic cichlid (Cichlasoma nigrofasciatum) and discus (Symphysodon aequifasciatus) were investigated by routine light and electron microscopies. The fertilized eggs of all three species were of the non-transparent, ellipsoidal, adhesive and non-floted type. The egg envelopes have a single micropyle, which is thought to the pathway of sperm in the area of the animal pole. In golden severum, an outer surface of egg envelope was covered by a reticular layer, that of convic cichlid was covered by an amorphous reticular layer and that of discus was covered by a branched reticular layer. The fertilized egg envelopes consisted of two distinct layers, an adhesive outer layer and an inner layer, consisted of lamellae alternating with interlamellae of lower electron density, in all three species; an inner layer of golden severum was $15\sim17$ layers, that of convic cichlid was $14\sim16$ layers, and that of discus was $18\sim19$ layers.
