Soil properties for the limestone-derived soil were examined to relate soil formation to stratigraphy of parent materials and hillslope positions in Bangjeol Ri, Yeongweol Eup, Gangweon Do. Pyeongchang, Anmi, Yulgog and Mungyeong series were described for topographic positions such as shoulder position, footslope, terrace and local bottom associated with toposequence where the landscape consisted of gently rolling hillslopes and nearly level plains. 1. Pyeongchang, Anmi, Yulgog and Mungyeong series had the standard hue of the 2.5YR, 5YR, 10YR and 2.5Y, respectively. Thus, color sequence of soil could be related to hillslope positions on the landscape. 2. With ascending slope toward summit, the clay content increased while silt content decreased 3. Silt/Clay ratios ranged from 0.27 to 3.76 and it was increased with descending to bottom. It, also, appeared that maturity of soil was higher at summit position than at bottom. 4. Soils developed in limestone were neutral in soil reaction and very low in available $P_2O_5$. OM, available $SiO_2$, CEC, and active Fe in soils seemed to be increased with ascending to summit position.

This article re-reads the messages of the text, 'Incendies', the uncanny actions and the strange words of protagonist Nawal, through the ideas of Jacques Lacan, particularly his notion of sexuation with posing questions about most of the previous reviews which are based on femininity or motherhood. For Lacan, masculinity and femininity are not biological essences but symbolic positions, and the assumption of one of these two positions is fundamental to the construction of subjectivity. So 'man' and 'woman' are merely signifiers that stand for these two subjective positions. Each side is defined by both an affirmation and a negation of the phallic function, by both an inclusion and exclusion of absolute non-phallic jouissance. Unlike the man, the woman is 'not-all' identified with the phallic function, demonstrating the undecidability and impossibility of totalising the woman. Although the woman is bound to do castration through being subject to the phallic function, she is also related to the signifier of the barred Other, S(Ⱥ) which stands for a gap or lack in the Other. Thus, as a consequence of not being entirely within the symbolic, she has an Other Jouissance, Feminine Jouissance, because it's possible to face emptiness of the Symbolic, the Real only in the place of the woman for new Ethics/Politics. This paper finds that Nawal is not completely defined by the phallic function and she is a subject of death drive that practices the signifying cut with passing through the fantasy as a screen for the desire of the Other. Nawal is situated on the position of the woman as 'not-all' unlike masculinity in Lacanian sexuation. This article shows that her strange acts are love, that is the true ethical acts. Above all her acts are related to the ethics of pure desire beyond the ethics of the Good of Aristotle. In that sense the character of Nawal of 'Incendies' is similar to the one of 'Antigone' as a character in all aspects. In psychoanalysis they all are true subjects that face a void, emptiness in a symbolic structure. They assume underlying impossibility of being/the Symbolic. They don't represent the images of compromise and peace in the normally accepted meaning of the word. A love that they show is not compassion but blind recognition of the excluded, embracing uniqueness of the excluded. This thesis finds resultingly Nawal's acts which can't be understood from viewpoint of feminism practice the ethics of the real, the politics of the real.

Brugada syndrome (BS) is an autosomal dominant inheritance cardiac arrhythmia disorder associated with sudden death in young adults. Thailand has the highest prevalence of BS worldwide, and over 60% of patients with BS still have unclear disease etiology. Here, we performed a new viral metagenome analysis pipeline called VIRIN and validated it with whole genome sequencing (WGS) data of HeLa cell lines and hepatocellular carcinoma. Then the VIRIN pipeline was applied to identify viral integration positions from unmapped WGS data of Thai males, including 100 BS patients (case) and 100 controls. Even though the sample preparation had no viral enrichment step, we can identify several virus genes from our analysis pipeline. The predominance of human endogenous retrovirus K (HERV-K) viruses was found in both cases and controls by blastn and blastx analysis. This study is the first report on the full-length HERV-K assembled genomes in the Thai population. Furthermore, the HERV-K integration breakpoint positions were validated and compared between the case and control datasets. Interestingly, Brugada cases contained HERV-K integration breakpoints at promoters five times more often than controls. Overall, the highlight of this study is the BS-specific HERV-K breakpoint positions that were found at the gene coding region "NBPF11" (n = 9), "NBPF12" (n = 8) and long non-coding RNA (lncRNA) "PCAT14" (n = 4) region. The genes and the lncRNA have been reported to be associated with congenital heart and arterial diseases. These findings provide another aspect of the BS etiology associated with viral genome integrations within the human genome.

This paper examines the positions and personnel of the Naeui system in the late Joseon Dynasty. First, the regulations of the Naeui system were investigated through the literature related to Naeuiwon. Next, the operation of the regulations, changes in the system, and causes were analyzed through the Seungjeongwon Diary (承政院日記). We discovered: 1) Naeuiwon's medical bureaucracy originally did not have a fixed number of positions, but gradually came into being with a quota regulation. Uiyagdongcham-ui (議藥同參醫) and Naechim-ui (內鍼醫) did not have a quota, but was initially set at 10 people, then expanded to 12 people. Originally, the royal physician had no fixed number, and in 1864 the first quota was 7 people. 2) 'Gyeom-eoui' and 'gachanaeui' served to expand Naeui's quota. After the mid-17th century, 'Gyeom-eoui' expanded the quota of royal physicians to secure a position for the medical bureaucracy of Naeuiwon. 'Gachanae' after King Jeongjo serves to add to the quota while obeying the provisions of the law. 3) The customary promotion of Naeuiwon's medical bureaucracy expanded and became stricter after the mid-19th century, during which special promotions became more frequent than in previous periods. As for the provision of appointment to the 6th class after 30 months, Uiyagdongcham-ui was established in 1686 and Naechim-ui was established in 1718, increasing the chance for customary promotion. In the case of Naeui, the regulation for the Secretary General to raise the degree of official rank has been strengthened since the Cheoljong era. However, special promotions were frequent in the mid-19th century because the number of high-ranking officers increased compared to the previous period. In conclusion, the Naeui system in the late Joseon Dynasty changed in the direction of strengthening their own privileges. The Naeuiwon's quota was increased and promotion was guaranteed through the system and customs. Since the mid-18th century, there have been some regulatory restrictions, but the framework has not changed. This is confirmed not only in the regulations of the documents related to the Naeuiwon, but also in the Seungjeongwon Diary. Naeuiwon's medical bureaucracy enjoyed superiority in promotion and status compared to other forms of technical bureaucracy.

This study presents a technique for assessing the dimensional quality of assembly parts in Prefabricated Steel Structures (PSS) using a stereo vision sensor. The stereo vision system captures images and point cloud data of the assembly area, followed by applying image processing algorithms such as fuzzy-based edge detection and Hough transform-based circular bolt hole detection to identify bolt hole locations. The 3D center positions of each bolt hole are determined by correlating 3D real-world position information from depth images with the extracted bolt hole positions. Principal Component Analysis (PCA) is then employed to calculate coordinate axes for precise measurement of distances between bolt holes, even when the sensor and structure orientations differ. Bolt holes are sorted based on their 2D positions, and the distances between sorted bolt holes are calculated to assess the assembly part's dimensional quality. Comparison with actual drawing data confirms measurement accuracy with an absolute error of 1mm and a relative error within 4% based on median criteria.

In this paper, we design and verify a system that can detect piping leakage noise in an environment with significant reverberation and reflection using a multi-channel acoustic sensor module as a technology to prevent major plant accidents caused by leakage. Four-channel microphones arranged in a tetrahedron are designed as a single sensor module to measure three-dimensional sound intensity vectors. In an environment with large effects of reverberation and reflection, the measurement error of each sensor module increases on average, so after placing multiple sensor modules in the field, measurement results showing locations with large errors due to effects such as reflection are excluded. Using the intersection between three-dimensional vectors obtained from several pairs of sensor modules, the coordinates where the sound source is located are estimated, and outliers (e.g., positions estimated to be outside the site, positions estimated to be far from the average position) are detected and excluded among the points. For achieving aforementioned goal, an excluding algorithm by deciding the outliers among the estimated positions was proposed. By visualizing the estimated location coordinates of the leakage sound on the site drawing within 1 second, we construct and verify a system that can detect the location of the leakage sound in real time and enable immediate response. This study is expected to contribute to improving accident response capabilities and ensuring safety in large plants.

For efficient soil water management in open fields, the proper use of soil moisture sensors is a prerequisite. Particularly in open-field environments like orchards with extensive root systems, the appropriate positioning of sensors is very important. The present study was conducted to identify the optimal placement of soil moisture sensors by assessing changes in soil water potential across various positions within orchard field soils after installing tensiometers. In apple and Asian pear orchards located in two regions of Korea, nine soil water potential sensors (TEROS 21, METER Group) were installed at distances of 20, 40, and 60 cm from the tree trunk and depths of 10, 20, and 30 cm from the soil surface, and monitored the soil water potential changes over two years. Results indicated that the positions closer to the tree trunk and the soil surface exhibited more pronounced changes in soil water potential. The greatest magnitude of change in soil water potential was observed at a distance of 20 cm and a depth of 10 cm, suggesting this position as the most suitable for soil moisture sensor installation. However, variations in the degree and pattern of changes in soil water potential were noted across sensor positions due to root system growth over time. Therefore, periodic observation and adjustments in sensor placement would be advisable to accurately monitor the soil moisture condition in long-term crops such as fruit trees in open fields.

The photochemical reaction of phenyl(tribromomethyl)mercury with nido-decaborane gives a new boron cluster expanded compound. The two borons at the 6- and 9- positions in decaborane behave as electrophilic centers for the reaction with dibromocarbene. The first step in this reaction is the addition of two molar equivalents of dibromocarbene which is produced from phenyl(tribromomethyl)mercury to nido-decaborane. In the second step the unstable intermediate generates the product, 1,2-$Br_2C_2B_{10}H_{10}$ through loss of H$_2$.

The effect of vesicular L-$\alpha$-phosphatidylcholine on the rate of formation of all-trans-N-retinylidene-n-butylamine (3) and on the regeneration kinetics of bacteriorhodopsin pigment from retinal and bacterio-opsin have been studied. An estimate of the relative positions of retinal and n-butylamine in the vesicles has been made by fluoresence quenching experiments. Partition coefficient of retinal and microviscosity of the retinal-binding region have also been determined. The results are discussed in terms of the nature of chemical interaction between retinal and amine in a lipid environment.
