Abstract Monitoring is the most critical element in implementing "forest carbon offset project" to enhance the visibility of CSR (Corporate Social Responsibility) in North Korea. This study is intended to explore monitoring potential in terms of forest carbon offset project using satellite image for Baekdu mountain of North Korea. The permanent record of standard satellite remote sensing system demonstrated its capability of presenting area-wide visual evidences of monitoring conditions in Mt. Baekdu mountain of North Korea (site suitability, carbon stock by forest biomass growth, carbon emission by forest biomass loss, deforestation and degradation, environmental, social and economic impact specified in the Carbon Sequestration Law). It doesn't seem very difficult to comply with monitoring requirements for "the forest carbon offset project" due to the probative value of satellite data. Therefore, it could be considerable or realistic approach to utilize CSR based forest carbon offset project as a point of reform and open-door in North Korea. It is anticipated that this research output could be used as a valuable reference for Korea-based enterprises to ensure monitoring potentials using satellite image in exploring forest carbon offset project sites in North Korea.

In this paper, we propose the chromatic adaptation models (CAM) for the variations of the luminance levels. A chromatic adaptation model, CAM$\Delta$Y , is proposed according to the change of luminance level under the same illuminants. The proposed model is obtained by the transform the test colors of the high luminance into the corresponding colors of the low luminance. In the proposed model, the optimal coefficients are obtained from the corresponding colors data of the Breneman's experiments. In the experimental results, we confined that the chromaticity errors, $\Delta$u'v', between the predicted colors by the proposed model and the corresponding colors of the Breneman's experiments are 0.004 in u'v' chromaticity coordinates. The prediction performance of the proposed model is excellent because this error is the threshold value that two adjacent color patches can be distinguished. Additionally, we also propose equal-whiteness CCT curves (EWCs) by CAM$\Delta$Y according to the luminance levels of the surround viewing conditions. And the proposed EWCs can be used as the theoretical standard which determines the reference white of the color display devices.

The ulnar nerve extends down the arm, across the elbow, and into the hand. It provides sensation to the little and ring fingers and activates many of the small muscles in the hand. The determination of peripheral nerve conduction velocity is an important part of ulnar nerve evaluation. The electrodiagnostic value as neurophysiologic investigative procedure has been known for many years but normal value of digital nerve was not reported in Korea. The purpose of this investigation was to measure the digital nerve conduction velocity of ulnar nerve for obtain clinically useful reference value and compare difference in each fingers and then compare with the other countries. 71 normal Korean volunteers (age, 19-65 years; 142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking II (EMG machine) was use for detected conduction velocity and amplitude of digital nerves in ulnar nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation and independent t-test was used to compare with ring and little finger. Conduction velocity of the right ring finger was 57.44m/sec and little finger was 55.32msec. The left ring finger was 55.55msec and little finger was 54.11msec. Amplitude of the right ring finger was $30.28{\mu}V$ and little finger was $48.36{\mu}V$. The left ring finger was $30.67{\mu}V$ and little finger was $52.76{\mu}V$. There were significantly difference between ring and little in amplitude (p<.05) but there were no statistically difference between conduction velocity of ring and little finger (p>.05). The amplitude of little finger are greater than ring finger. The present results revealed that electodiagnosis can easily perform in little finger for digital nerve of ulnar nerve study.

The Chevron saga including Chevron/TexPet v. Ecuador, PCA Case No. 34877(hereinafter referred to as "Chevron I") and Chevron/TexPet v. Ecuador, PCA Case No. 2009-23(hereinafter referred to as "Chevron II") started out of domestic litigations between TexPet and Ecuador in the early 1990s. In Chevron I, the Tribunal decided that Article 2(7) of the U.S.-Ecuador BIT on effective means of provision was breached because of undue delays in the seven legal proceedings TexPet had brought against Ecuador in respect to contractual obligations. In Chevron II, it was contended that through the actions and inactions of the judiciary and the executive, Ecuador breached her several obligations under the BIT. Ecuador objected to the jurisdiction of the Tribunal because TexPet's investment was terminated in 1992, and because Chevron is not a party to the 1995 Settlement Agreement and 1998 Final Release. In its Interim Award on Jurisdiction and Admissibility, the Tribunal applied a prima facie standard to the facts alleged by the Claimants but denied by the Respondent, and decided that questions in respect of the Respondent's jurisdictional objections should be joined to the merits under Article 21(4) of the UNCITRAL Arbitration Rules. In the merits phase of Chevron II, the Tribunal divided the merits of the Parties' dispute into two parts, entitled "Track 1" and "Track 2". In its Partial Award on Track 1, the Tribunal decided that Chevron is a "Releasee" under the 1995 Settlement Agreement. In a decision on "Track 1B", the Tribunal decided that the Lago Agrio complaint cannot be read as pleading "exclusively" or "only" diffuse claims, and that, to this extent, the Claimants' reliance on the 1995 Settlement Agreement as a complete bar to the Lago Agrio complaint must fail, as a matter of Ecuadorian law. The Tribunal maintained the position that the Parties' disputes on both merit and jurisdiction should be reserved for Track 2. It remains to be seen how the Tribunal addresses the Claimants' allegations of multiple denials of justice under international law against the judgments of the Respondent's Courts, together with the Respondent's jurisdictional objections in Track 2 of the arbitration.

Cultivation of competent manpower is recognized as one of the important factors in the development of fisheries as well as of other industries. For reference to the development of education of fisheries high schools in the Republic of Korea, the author carried out a study on the education in Japan. The reason is why the education on fisheries had been initiated in Japan and her educational system has played the role of a model for neighboring countries. Even though the education on fisheries tends to shrink a little in recent years by diffusing the unwilling tendency to engage in 3D (dirty, difficult and dangerous) jobs, there are fifty-one high schools educating fisheries in Japan. Thirty-eight of them are specialized fisheries high schools and the others are comprehensive high schools to put common course and fisheries course together. In the first step of study, the goal of education on fisheries, organization of department and arrangement of curriculum are analysed. 1. In the newly arranged curriculum which will come into effect from 1994, the goal of education on fisheries is set up as "By educating fundamental knowledge and technology on the production and circulation in the field of fisheries, have students understand the significance and role of fisheries, and so cultivate ability and active attitude to the development of fisheries". The goal means that the circulation of fishery products are regarded as important as the production itself, and active attitude to the development of fisheries is also stressed, different from the present goal. 2. Standard departments directed by the Government are set up as five-Departments of Marine Fishing, of Fisheries Engineering, of Information Communication, of Fish Culture, of Sea Foods. But they are actually organized and named by the founders of schools-local government. Then there are many unique-named departments and the management of schools are somewhat flexible according to the situation of local district. 3. Special subjects are revised to twenty-four in the new curriculum from twenty-two in the present curriculum. Among them the contents are widely revised in the subjects such as Introduction to Fisheries, Fisheries Engineering, Communication Engineering, Communication Technology, Fish Culture. On the other hand, five subjects such as Information Treatment on Fisheries, Information Technology on Fisheries, Subjective Study, Fisheries Economics, Circulation of Sea Foods are newly set up to meet the changing phase of the time.

Sonic nozzles have been a standard device for measurement of steady state gas flow, as recommended in ISO 9300. This paper introduces two sonic nozzles of diameter ${\Phi}$ 0.03 mm and ${\Phi}$ 0.2 mm precisely machined according to ISO 9300. The constant volume flow meter(CVFM), readily set up in the Vacuum center of KRISS. was used to calibrate the discharge coefficients of both nozzles. The calibration results were shown to determine them within the 3% expanded measurement uncertainty. Calibrated sonic nozzles were found to be applicable for precision measurement of steady state gas flow in the vacuum process in the ranges of 0.6~1,800 cc/min. Those flow conditions are equivalent to the fine gas flow with Reynolds numbers of 26~12,100. Those encouraging results confirm that calibrated sonic nozzles enable precision measurement of extremely low gas flow encountered very often in th vacuum processes. Both calibrated sonic nozzles are proven to provide the precision measurement of the volume flow rate of the dry vacuum pump within one percent difference in reference to CVFM. Calibrated sonic nozzles are applied to a new 'in-situ and in-field' equipment designed to measure the volume flow rate of vacuum pumps in the semiconductor and flat display processes. Furthermore, they can provide other applications to flow control devices in vacuum, such as MFC, etc.

In this study, to build a spatial information infrastructure, which is a component of a smart city, a 3D digital twin model in the downtown area was built based on the latest spatial information acquisition technology, the drone. Several analysis models were implemented by utilizing. While the data processing time and quality of the three types of drone photogrammetry software are different, the accuracy of the construction model is ± 0.04 in the N direction and ± 0.03m in the E direction. In the m and Z directions, ± 0.02m was found to be less than 0.1m, which is defined as the allowable range of surveying performance and inspection performance for the boundary point in the area where the registration of the boundary point registration is executed. 1: 500 to 1 of the aerial survey work regulation: The standard deviation, which is the error limit of the photographic reference point of the 600 scale, appeared within 0.14 cm, and it was found that the error limit of the large scale specified in the cadastral and aerial survey was satisfied. In addition, in order to increase the usability of smart city realization using a drone-based 3D urban digital twin model, the model built in this study was used to implement Prospect right analysis, landscape analysis, Right of light analysis, patrol route analysis, and fire suppression simulation training. Compared to the existing aerial photographic survey method, it was judged that the accuracy of the naked eye reading point is more accurate (about 10cm) than the existing aerial photographic survey, and it is possible to reduce the construction cost compared to the existing aerial photographic survey at a construction area of about 30㎢ or less.

For the optimization of thermal processing conditions in soymilk process, 4 strains of thermoresistant flat-sour bacteria were isolated from soymilk. The isolates were aerobic spore-forming rods, and grew at $-65^{\circ}C$. Based on the morphological and physiological properties, all of the isolated strains were identified as Bacillus stearothermophilus. The heat resistance of spores of 3 isolates and Bacillus stearothermophillus ATCC 12980 as a reference was determined in soymilk(pH 7.0) and pH 7.0 buffer solution. For each of the spores studied, linear regression equations with standard error were presented for the thermal destruction at 110, 115, 121, and $125^{\circ}C$. It was not obvious that the components of soy milk increased the heat resistance of spores. Between the strains studied, variability was noted in the D values at the different temperature, and no one strain was consistently the most heat resistant at all the given temperatures. The average D value for the 4 strains was 77.27, 20.20, 2.76 and 1.39 min at 110, 115, 121 and $125^{\circ}C$, respectively, and the average z value was $8.36^{\circ}C$.

Background: Line probe assay (LPA) is standard diagnostic tool to detect multidrug resistant tuberculosis. Non-interpretable (NI) results in LPA (complete missing or light wild-type 3 and 8 bands with no mutation band in rpoB gene region) poses a diagnostic challenge. Methods: Sputum samples obtained between October 2016 and July 2017 at the Intermediate Reference Laboratory, All India Institute of Medical Sciences Hospital, New Delhi, India were screened. Smear-positive and smear-negative culture-positive specimens were subjected to LPA Genotype MTBDRplus Ver 2.0. Smear-negative with culture-negative and culture contamination were excluded. LPA NI samples were subjected to phenotypic drug susceptibility testing (pDST) using MGIT-960 and sequencing. Results: A total of 1,614 sputum specimens were screened and 1,340 were included for the study (smear-positive [n=1,188] and smear-negative culture-positive [n=152]). LPA demonstrated 1,306 (97.5%) valid results with TUB (Mycobacterium tuberculosis) band, 24 (1.8%) NI, three (0.2%) valid results without TUB band, and seven (0.5%) invalid results. Among the NI results, 22 isolates (91.7%) were found to be rifampicin (RIF) resistant and two (8.3%) were RIF sensitive in the pDST. Sequencing revealed that rpoB mutations were noted in all 22 cases with RIF resistance, whereas the remaining two cases had wild-type strains. Of the 22 cases with rpoB mutations, the most frequent mutation was S531W (n=10, 45.5%), followed by S531F (n=6, 27.2%), L530P (n=2, 9.1%), A532V (n=2, 9.1%), and L533P (n=2, 9.1%). Conclusion: The present study showed that the results of the Genotype MTBDRplus assay were NI in a small proportion of isolates. pDST and rpoB sequencing were useful in elucidating the cause and clinical meaning of the NI results.
