To be helpful to the treatment of pulmonary cancer with oriental medicine, we got clinical reports together and analyzed the data. The results were obtained as follows: 1. The treating methods could be summarized as three methods that were reinforcing vital energy, eliminating harmful Qi, and reinforcing vital energy with eliminating harmful Qi. The methods of reinforcing vital energy were supplementing Qi & Yin, increasing pahological heat & reinforcing kidney, augmenting Qi & blood, supplementing vital energy and strengthening fundermental energy, reinforcing spleen and increasing Qi, lubricate Yin and lung, and the other methods of eliminating harmful Qi were transforming pathological fluid and softening, clarifying heat and eliminating poison, dipersing lung and softening, toxicding and softening, guiding Qi and activating blood, clarifying heat and dispersing lung, guiding Qi and counteracting stress etc., and the methods of supplementing vital energy with eliminating poison were reinforcing spleen and transforming pathological fluid, increasing Qi and activating blood, supplementing Yin and clarifying heat, reinforcing spleen and dry the dampness, lubricating lung and transforming patholigical fluid and supplementing Qi and activating blood. 2. The oriental prescriptions used for pulmonary cancer were Chunkeum-Weekyungtang & Sohamhwingtang, Jinhayookgunjatang, Hyulboochukeotang, Bokbangkyogonamtang was reported to be effective in the treatment of metastasis. 3. Bokbangshinjingtang and haewool were applied for the complications of pulmonary cancer, Soshihotang for fever, hangamryung for tumor pain. Prunus ansu Komarov, Eriobotrya japonica Lirdley, Pyrrosiae lingua Farwel, Steomon japonica Miguel, Maximowiczia chinensis Ruprecht var, Morus bombycis Koidzumi for cough, Panax Pseudo-ginseng Wall. var, Bletilla striata Reichenbach f., Acacia catechu(兒茶) for hemoptysis, Lonicerae flos, Aspongopus chinensis(九香蟲) for chest pain, Cypsum Fibrosum, Gazella gutturosa, Scutellaria baicalensis Georgi, Gypsophila oldhamiana Miquel for fever, Lepidii semen descurainiae semen, Belamcanda chinensis D.C, Gnaphalium affine(佛耳草) for asthma. 4. For the reduction of side effect by chemotherapy and radiotherapy it was known that supplementing Qi was used chiefly for side effect of chemotherapy and augmenting Yin applied to side effect of radiotherapy. 5. The oriental presciptions were suggested for the side effect by chemotherapy and radiotherapy ; Sammaekaek(參麥液), Whaebokwontang(化瘀復元湯), Hwangjungomitang(黃精五味湯), Yukmijihwangtang(六味地黃湯), Hyangsayukgunjatang(香砂六君子湯), Samlyeekulsan for side effect by chemotherapy while Geumgweisingiwhan, Hwanglyentang(黃連湯), Hwanglyenhaedoktang(黃連解毒湯), Yangyeunchungpeitang(養陰淸肺湯), Idongtang(二冬湯), Jayeunkanghwatang(滋陰降火湯) for side effect by radiotherapy.

Results obtained from the experiment conducted to find out e relationships between tuber decay, and water potential and bruising in or on the tubers, are summerized as follows ; 1) When potato tubers were bruised or injected with bacterial inoculum, the tubers with high water potential rotted more easily than the tubers with low potential. A big difference in the development of decay between high and low water potential tubers was found. 2) In tubers injected with different levels of inoculum. high water potential tubers were more susceptible to soft rot than low water potential tubers. 3) $ED_{50}$ of inoculum concentration was 8.5(log) at high water potential tubers and 9.8(log) at low water potential. A small difference between low and high water potential was detected. The results of this experiment show that potatoes should be handled carefully and must be dried after harvest to reduce decay development in shipment and storage.

This study was performed in order to examine the functional and quality characteristics of raw noodles with added kale powder. The raw noodles were prepared at a concentration of 4, 8, and 12% (w/w) of the kale, based on flour weight. The antioxidant activity of kale powder, specifically DPPH free radical scavenging, reducing activity, and total phenolic content were found to be 75.16%, 1.24 (O.D.) and 44.47 mg GAE/g, respectively. Using Hunter Lab color values for raw noodle with added kale powder, L (lightness) values decreased with an increased concentration of kale powder, whereas a (redness) values decreased (p<0.001). In a texture analysis, chewiness (p<0.01), gumminess (p<0.001), and cohesiveness (p<0.001) increased significantly as the amount of added kale powder increased. According to sensory evaluations: color, flavor, taste, texture, and overall palatability had the highest score in noodle with 8% kale powder (p<0.001). During periods of storage, moisture contents were decreased when kale powder concentrations increased, but pH did not differ in any of the groups and bacteria cell counts were between 0% and 8%. Kale noodles were observed at 8% then 0%, decreased by 102 log CFU/g. The antioxidant activities of raw noodles with added kale powder were increased by 8%, a 30~50% increase over the control group. These results suggest that kale powder is useful as a functional food resource with antioxidant activities.

In vitro high-frequency plant regeneration of Muscari comosum var. plumosum through somatic embryogenesis was obtained via two developmental pathways: direct embryos and multiple shoots regenerated from embryogenic callus. Flower bud with pedicel, receptacle, petal and ovary wall, floral stalk and leaf as explants were cultured in MS medium supplemented with various plant growth regulators. Embryos formed directly from pedicel, receptacle and floral stalk. Depending on explant sources, the optimal medium was MS medium supplemented with 0.2 mg/L IBA and 0.3 mg/L BA, 3.0 mg/L IBA and 3.0 mg/L BA, and MS-free medium for pedicel, receptacle, and floral stalk, respectively. Multiple shoots regenerated from embryogenic cal]i which was initiated from petal, ovary and leaf were observed in MS medium with different concentrations and combinations of hormone. The most suitable medium for each type of explant was 3.0 mg/L IBA and 3.0 mg/L BA(petal and ovary) and 5.0 mg/L IBA and 5.0 mg/L BA (leaf) Furthermore, the combination of 0.1 mg/L 2,4-D and 1.0 mg/L BA was also good for all sources of explants not only for direct embryo formation, but also, for embryogenic callus induction.

This study was carried out to investigate the developmental process of plant community during the secondary succession and changes of soil properties in the burned areas lapsed 28 years after the forest fire in Mt.Palgong. The forest fire occurred on March, 1969 and the red pine (pinus densiflora) forest and its floor vegetation were burned down. The results are summarized as follows: the floristic composition of burned and unburned areas were composed of 49 and 48 species of vascular plants, respectively. The dominant species based on SDR4 of the burned sites were Lespedeza maximowicxii(87.75), Carex humilis (62.94), Rhododendron schippenbachii(55.78) and Miscanthus sinensis var.purpurascens (51.94). In contrast, Pinus densiflora (81.17), Quercus serrata (53.58)m Carex humilis (53.11) and Miscanthus sinenis var. purpuracens (52.42) were dominant in the unburned area. The biological spectra showed the $H-D_1-R_5-e$ type in both areas. The indices of similarity (CCs) between the two areas were 0.80. Degree of succession (DS) was 734 in the burned area and 809 in the unburned area. The species diversity (H) and evenness indices (e) in the burned and unburned areas were 2.05, 2.13 and 0.53, 0.55, respectively. Dominance index (C) in the burned and unburned areas were 0.30 and 0.32, respectively. Soil properties such as soil pH, content of organic matter, total nitrogen, total carbon, exchangeable potassium, sodium, calcium, and magnesium in burned area were comparatively higher than those of unburned area. Monthly changes of soil properties were of little significance except for some cases. These results suggest that there was relationship between trend of vegetation recovery and the changes of soil properties after the forest fire. Mixed forestation of fire-resistant species and nitrogen fixation species will be effective for reforestation after the forest fire.

A Ypsolophid moth Saridoscelis sphenias Meyrick was recorded in 2020 first in Korea, and specimens were collected from Jindo and Wando in Jeonam province from 2016 to 2017. This moth uses host plants such as Pieris japonica (Thunb.) D. Don ex G. Don, Vaccinium bracteatum Thunb. and Leucothoe grayana Maxim. var oblongifolia (Miq.). This species was discovered once in a blueberry orchard in Jeju in August 2014, and since then it has been regarded as not an established species because of no further detection. However, S. sphenias was found again in blueberry orchards grown in vinyl houses in Jeju city and Seogwipo city in 2018 and 2019. Since 2020, this pest has also been found on field-grown blueberries. Hatched larvae first bored into new shoots and fed inside, and the mid-aged larvae escaped from the inside of shoots, attached several shoots with webs, and fed on the leaves in the group. It is considered that S. sphenias will become a severe pest on blueberries; thus, we report the basic life cycle here.

To develop natural therapeutic agents for acne vulgaris, we investigated antibacterial and anti-inflammatory effects of various medicinal plant extracts. Among candidate extracts, we selected Psoralea corylifolia L. extract (AC-1) and Magnoliae officinalis extract (AC-2) which showed the relatively high antibacterial effects, and Inula helenium L. extract (ACF-1) and Chrysanthemum zawadskii var. latilobum extract (ACF-2) which showed the relatively high anti-inflammatory effects for further investigations. All of them did not show cytotoxic effects below the concentration of $50{\mu}g/mL$. The antibacterial effects of AC-1, AC-2 and extract complex (AC) against P. acnes were 2.8, 2.5 and 3.2 times higher than that of 10 % salicylic acid respectively. And the antibacterial effect of AC-2 and extract complex against S. aureus were 1.4 and 1.5 times higher than that of 10 % methylparaben respectively. Also, it was shown that ACF-1, ACF-2 and extract complex had anti-inflammatory effects. All of them exhibited inhibitory effects for the secretion of IL-8 and TNF-$\alpha$ from THP-1 cells activated by heat-killed P. acnes. They reduced about 27 %, 38 %, 44 % of IL-8 secretion and 90 %, 88 %, 90 % of TNF-$\alpha$ secretion at concentration of $50{\mu}g/mL$ respectively. These results showed that the complex of medicinal plant extracts, AC-1. AC-2, ACF-1, and ACF-2, had therapeutic effects to acne vulgaris through antibacterial and anti-inflammatory effects. Therefore, we suggest that extract complex of AC-1, AC-2, ACF-1 and ACF-2 may be used as a useful agent for development of natural cosmetics which have therapeutic effects to acne vulgaris.

This experiment was conducted to evaluate effect of various hormones on callus induction, and on plantlet formation on various media, and to detect of Londax [Methyl 2-[[[[[(4,6-dimethoxy pyrimidin-2-yl) amino] carbonyl] amono] sulfonyl) methyl] benzoate] and Basta[Ammonium-(3-amino-3-carboxy-propyl)-methyl phosphinate] on callus growth and reaction of succinate dehydrogenase in callus against TTC, using various species such as Eleocharis kuroguwai, Cyperus serotinus, Oryza sativa (samgangbyeo) and Echinochloa crusgalli P. Beauv. var. caudata Kitagawa. The optimal levels of 2,4-D in MS medium seems to be different among species tested, 2.0 ppm for rice and E. crusgalli, 1.0 ppm for Eleocharis kuroguwai, and 4.0 ppm for C. serotinus derived callus from shoot-tip. In case of combination of 2,4-D with BA, 1.0 plus 0.3 ppm appeared the most appropriate level to induce callus from rice and E. kuroguwai, and I.0 plus 0.1 ppm for C. serotinus and E. crusgalli. When 2,4-D treated with TIBA, 1.0 plus 0.5 ppm appeared the most appropriate rates to induce callus derived from seeds of rice, E. crusgalli, seeds of C. serotinus and E. kuroguwai, 1.0 plus 0.3 ppm for shoot-tip of C. serotinus. Positive reaction of succinate dehydrogenase against TTC was observed regardless of calli and herbicides tested, indicating that they all are alive, and these herbicides were not able to kill the calli tested within the short period of time 20 hrs treatment. Regardless of plant species used, the rate of plantlet formation from callus was very low. However, some plantlet formed from E. crusgalli at 0.8 ppm of 2,4-D plus 8.0 ppm of kinetin, and from E. kuroguwai at 1.6 ppm of 2,4-D plus 16.0 ppm of kinetin, showing effectiveness of 2,4-D with kinetin mixture treatment. No callus was induced from C. serotinus treated with Basta from $10^{-6}M$ to $10^{-3}M$. In general, rice was the least susceptible to Basta among plant species tested, followed by E. crusgalli, and E. kuroguwai. In Londax treatment, rice showed the least inhibition rate in callus growth. Callus was induced from rice even at $10^{-3}M$ of Londax. However, $10^{-3}M$ of Londax completely inhibited callus induction from the test species. Rice showed most tolerant to both herbicides, indicating the existence of different responses among plant species.

We present the analysis of KMT-2016-BLG-0212, a low flux-variation ($I_{flux-var}{\sim}20mag$) microlensing event, which is in a high-cadence (${\Gamma}=4hr^{-1}$) field of the three-telescope Korea Microlensing Telescope Network (KMTNet) survey. The event shows a short anomaly that is incompletely covered due to the brief visibility intervals that characterize the early microlensing season when the anomaly occurred. We show that the data are consistent with two classes of solutions, characterized respectively by low-mass brown-dwarf (q = 0.037) and sub-Neptune (q < $10^{-4}$) companions. Future high-resolution imaging should easily distinguish between these solutions.
