This study was conducted to establishment of in vitro micropropagation through induction of multiple shoots from axillary bud culture in Calanthe discolor Lindl. Shoots initiation from axillary bud was the most effective on half strength MS medium supplemented with $0.5mg{\cdot}L^{-1}$ NAA and $2.0mg{\cdot}L^{-1}$ TDZ during four weeks of dark culture followed by culture under a 16-h photoperiod. Multiple shoots (12.5 shoots per explant) were proliferated on half strength MS medium containing $4.0mg{\cdot}L^{-1}$ TDZ and $2.0mg{\cdot}L^{-1}$ IBA. On the other hands, the abnormally emerged shoots during the multiple shoot proliferation stage were recovered to normal shoots on half strength MS hormone free medium. Multiple shoots were well elongated and rooted on half strength MS medium with $0.1mg{\cdot}L^{-1}$ NAA. The plantlets were acclimatized up to 100% on TKS substrate after pretreating with $10mg{\cdot}L^{-1}$ NAA for 30 min. and these plantlets showed good growth as well.

The evolution of civil engineering technology, exemplified by recent milestones like the completion of the Gangnam Global Business Center (GBC), has fostered the construction of expansive civil and architectural structures both above and below the earth's surface. This surge in construction necessitates a commensurate advancement in research and technology pertaining to safety protocols applicable to these vast edifices. Such protocols encompass a spectrum of concerns, ranging from the preemptive mitigation of accidents to the effective management of exigencies such as fires. As the trajectory of construction endeavors continues unabated, encompassing both subterranean and elevated domains, a concomitant imperative emerges to refine the methodologies underpinning precise indoor positioning. To address this need, an innovative web-based simulator has been devised to emulate indoor positioning scenarios for rigorous testing. This research further entails the development of an indoor positioning data Application Programming Interface (API) fortified by Geographic Information System (GIS) spatial operation techniques. This API is anchored in the construction of intricate test data, centered on the spatial layout of building 13 at the Electronics and Telecommunications Research Institute (ETRI). Consequently, the study renders feasible the expeditious provisioning of diverse signal-based and image-based spatial information, pivotal for enhancing the navigational acumen of mobile devices. Path delineation, cellular signal mapping, landmark identification, and ancillary navigational aids are among the manifold datasets promptly furnished by the indoor positioning data API. In summation, this study engenders a crucial leap towards the fortification of safety protocols and navigational precision within the expansive confines of modern architectural wonders.

The vertical profiles of natural ²¹⁰Pb, ²¹⁰Po and ²³⁴Th activities were measured for the upper 100 m of water column at three stations in the middle region of the Korean East Sea during May 1992. And the distribution of these radionuclides was discussed associated with the formation of warm eddy or water mass. The main thermocline was maintained between the depth of 50 and 100 m at the southern station (Sta. A1), and between the depth of 10 to 50 m at the coastal station of Sockcho (Sta. B10). Contrastingly, a main thermocline at Sta. A10, which locates near the center of warm eddy, was observed below 230 m depth. Between 50 and 220 m depth of Sta. A10 is there a relatively homogeneous water mass of 10.1${\pm}$0.5$^{\circ}C$, which is significantly higher in temperature and lower in nutrient than the other two stations. It seems to be due to sinking of the warm surface water in which nutrients were completely consumed. Both ²¹⁰Pb and ²¹⁰Po show the highest concentration at Sta. A1 and the lowest at Sta. B10 among the three stations. Also, the ²¹⁰Pb activity is generally higher in the upper layer than in the lower layer, while ²¹⁰Po activity represents the reversed pattern at all three stations. At Sta. A1 and Sta. B10, the activities of ²¹⁰Po relative to its parent ²¹⁰Pb were deficient in the water column above the main thermocline, but were excess below the thermocline. However, the station near the center of warm eddy(Sta. A10), shows no excess of ²¹⁰Po in the depths below 50 m, although its defficiency is found in the upper layer like the other stations. At Sta. A1 and b10. ²³⁴Th activities are slightly lower in the surface mixed layer than in the deeper region However, at Sta. A10, ²³⁴Th activity in the upper 30 m is higher than below 50 m or in the same depth of the other stations, probably because of the high concentration of particulate matter. The residence time of ²¹⁰Po in the surface mixed layer at Sta. A10 is 0.4 year, much shorter than at the other two stations(about one year). Above 100 m depth, the residence times of ²³⁴Th range from 18 to 30 other two stations(about on year). Above 100 m depth, the residence times of ²³⁴Th range from 18 to 30 days at all stations, without significant regional variation. The percentages of recycled ²¹⁰Po within the thermocline are 39% and 92% at Sta. A1 and Sta. B10, respectively. Much higher value at Sta. B10 may be due to a thin thickness of the mixed layer as well as the slower recycling rate of ²¹⁰Po in the main thermocline.

Vertical profiles of $^{210}Po\;and\;^{210}Pb$ were measured for the upper 100 m of water column at six stations in the middle region of the Korean East Sea during March 1993. The distribution patterns of these radionuclides with the water mass and controlling factors on their distributions were also discussed. $^{210}Pb$ activities were generally high at surface water and gradually decrease with depth. Vertical profiles of $^{210}Po$ were relatively homogeneous except for at station E3, where chlorophyll-a concentration was the highest and $^{210}Po$ activity in the upper 30 m was lower than below 50 m. The $^{210}Po$ activities relative to its parent $^{210}Pb$ at all stations were deficient at the upper 30 m, but were excess or nearly equilibrated values below 50 m. The magnitude of $^{210}Po$ deficiency was relatively high at station E3 and E6, where strong thermocline occured. However, $^{210}Pb$ activities showed strong excess in the upper 100 m of all stations, compared with its parent $^{226}Ra$. The residence time of $^{210}Po$ ranged from 1.0 to 7.8 years, and was relatively short at station E3 and E6. The data obtained at the upper 50 m water column during $1992\~1994$, also showed that removal rate constant of $^{210}Po$ and inventories of chlorophyll-a was negatively related. This indicates that the primary production plays an important role in controlling the distributions of $^{210}Po$ at the upper water column of the Korean last Sea in spring. While, inventories of excess $^{210}Pb$ was generally decreasing with increasing density difference between 50 m and 100 m, suggesting that $^{210}Pb$ concentrations in the upper water column were controlled by stability of water column.

This study investigated the quality characteristics of cream soup added with Pleurotus eryngii powder. Pleurotus eryngii was dried in a hot air dryer at $40^{\circ}C$ for 8 hours and at $60^{\circ}C$ for 8 hours. The dried Pleurotus eryngii was pulverized using a pin mill, and the powder was sieved through a 60~100 mesh. Sensory evaluations of cream soup added with different-sized particles of Pleurotus eryngii powder were performed. Cream soup added with Pleurotus eryngii powder of particles below $150{\mu}m$ showed good appearance, taste, and mouth-feel. Quality characterization of cream soup added with 5~20% Pleurotus eryngii powder showed that L value decreased with increasing Pleurotus eryngii, whereas a and b values increased. Sensory evaluations revealed that cream soup with 15% Pleurotus eryngii powder had significantly better taste, mouth-feel, and overall acceptability (p<0.05) than other samples. Thus, cream soup with 15% Pleurotus eryngii powder of particle size below $150{\mu}m$ was the most desirable and could be successfully used as convenience food in the food processing industry.

Background: Bronchioloalveolar cell carcinoma today needs further studies as an early diagnosis will drastically improve the chances of cure. Methods: Twenty-four cases of bronchioloalveolar cell carcinoma for the period of 5 years were studied in terms of incidence, age, sex, underlying diseases, symptoms, radiographic findings, methods of diagnosis, clinical and pathologic staging, methods of treatment, and survival retrospectively. Results: No correlation was found between patients' age, sex and underlying diseases. Most common symptoms were cough(62.5%), chest pain(29.2%), and sputum(29.2%). Of the 24 cases, 13 patients(54.2%) had solitary nodule, 6 patients(25%) had multiple nodules. At the time of diagnosis, 3 patients(12.5%) had the stage I diseases, 3 patients(12.5%) had the stage II diseases, 4 patients(16.7%) had the stage IIIa diseases, 3 patients(12.5%) had the stage IIIb diseases, and 11 patients(45.8%) had the stage IV diseases. 14 cases(58.3%) were found inoperable at the time of admission; they all died within 17 months. In 7 cases with stage I, II, IIIa diseases curative resection were attempted, in 1 case with stage IV disease wedge resection for palliative management was performed, and in 4 cases patients were still alive at the time of conclusion of this study. Conclusion: We conclude that early diagnosis of disease will increase operability and improve chances of survival and that aggressive diagnostic workup for suspicious pulmonary infiltrate is essential as early operation offers the best chances of cure.

This study investigated the effects of diets with a supplement of Job's tears (JT) and Cudrania tricuspidata leaf (CTL) powder as a functional food ingredient on obesity and lipid profiles in diet-induced obese rats. Male Sprague-Dawley rats were fed a high-fat diet (D12492, 45 kcal fat) for 5 weeks during the first phase. In the second phase, which lasted 5 weeks, the rats were divided into four experimental groups. The groups were a high-fat diet group as a control (HFD), a high-fat diet with 10% JT powder supplement group (JT-10), a 10% CTL powder supplement group (CTL-10), and a 20% JT and CTL 1:1 mixed-powder supplement group (MIX-20). The adipose tissue (RFP, EFP) weights were significantly decreased in the CTL-10 and MIX-20 groups than in the HFD group (p<0.05). The fecal weight produced by the MIX-20 group was highest among all experimental groups (p<0.05), and it was significantly increased during the second phase compared to the first phase (p<0.05). The serum total cholesterol content was significantly decreased in the CTL-10 and MIX-20 groups, and the LDL-cholesterol content was significantly low in the JT-10 and MIX-20 groups than in the HFD group (p<0.05). The blood glucose levels were significantly decreased in all experimental diet supplement groups than in the HFD group (p<0.05). The findings show that a diet of mixed JT and CTL could improve lipid metabolism.

This study investigates the effects of diets with mulberry leaf and Cudrania tricuspidata leaf supplements on blood glucose-related biomarkers in streptozotocin-induced diabetic rats. Male diabetic Sprague-Dawley rats were divided into groups and fed several diets. Group A was fed a diet with a 10% supplement of mulberry leaves. Group B was fed a diet with a 10% supplement of mulberry leaves and an additional 10% supplement of Cudrania tricuspidata leaves. Group C was fed a diet with a 10% supplement of mulberry leaves and an additional 30% supplement of Cudrania tricuspidata leaves. Group D was fed a diet with a 10% supplement of Cudrania tricuspidata leaves. Group E was the DM control. All diets were based on AIN-93G diet and they all lasted 6 weeks. The blood glucose levels of groups B and C stayed similar to initial levels (reference blood glucose) for the experimental period, which was significantly lower than levels in groups A, D, and E at the 6th week (p<0.05). And the area under the blood glucose curve (AUC) was also significantly lower in groups B and C than in groups D and E (p<0.05). The fasting blood glucose level after the experiment was significantly lower in groups B and C (p<0.05), and the C-peptide content of group C was as high as 50 pmol/L on average. The HbA1c content was also significantly lower in groups A and B than in group E (p<0.05). The serum TG, AST, and ALT levels were significantly decreased in groups A, B, and D than in group E (p<0.05). From the findings, it is shown that a diet of 1:1 mulberry and Cudrania tricuspidata leaf supplements could improve blood glucose-related biomarkers.

The sensory characteristics of red wine Gerbong (G), Campbell (C), Moru (M), Gerbong ＋ Moru (70 : 30, GM), Gerbong + Campbell (70 : 30, GC) and French wine (F, Carbernet Sauvignon, 1998) were evaluated. The preferences of color, flavor, taste and total evaluation were determined by a ranking test, and the organoleptic characteristics were evaluated by a quantitative descriptive analysis (QDA) method. The mean color scores of C, GM, F, GC, M and G were 4.74, 3.94, 4.67, 3.70, 2.65 and 1.47, respectively (p<0.001). The order for the mean score for flavor was GM (4.12) = M (3.94) = C (3.76) = F (3.76) ${\geq}$ GC (3.12)>G (2.29) (p<0.01), and the order for taste was F (4.75) ${\geq}$ C (4.25) ${\geq}$ GM (3.37) = GC (3.50) ${\geq}$ G (2.75) = M (2.37) (p<0.001). The total evaluation of mean scores showed G, M, C, GM, GC and F were 237, 2.44, 4.06, 3.87, 3.64 and 4.81, respectively (p<0.001). Influences of sensory characteristics on the total evaluation, in percentages, were 69.3% for taste, 3.7% for color, and 1.5% for flavor. The influences of taste, color, and flavor in red wine were 17% for sweet, acid, bitter and salty taste, 28.9% for purple and red color, and 14.4% for grape flavor. The attributes of the purple and red colors showed a positive correlation with grape flavor, oak flavor, grape taste, and floral tastes, but a negative correlation with $SO_2$, flavor. The attribute of sweet taste showed a positive correlation with grape flavorand floral flavor, but a negative correlation with bitter and astringency tastes, according to Pearsons correlation analysis (p<0.01).
