Medicinal plants are of great importance in providing healthcare to a large portion of the population in Korea. A number of plants are described in Dong-Ui-Bo-Gam for use in the treatment of allergic disorders, namely psoriasis, eczema, bronchial asthma, etc. In this study, we evaluated the effect of AllerQ, which is multi-complexes of various plants extracts such like Mori folium, Scutellaria baicallensis, Glycyrrhiza uralnsis, Mentha sacharinensis and Poncirus trifoliata on compound 48/80 induced anaphylactic shock, ovalbumin induced asthma in vivo and anti-IgE antibody induced hypersensitivity in vitro. We found antianaphylactic or antiallergic properties of AllerQ when given orally. AllerQ for prophylactic treatment for anaphylactic shocks have produced good results. AllerQ may modulate various aspects of immune function and allergic inflammation. In the present study, we analyse the effects of AllerQ on mast cell degranulation, mortality, cAMP/cGMP, O₂, H₂O₂ level, cyokine production and on the elicitation of IgE-mediated mast cell-dependent allergic inflammation in vivo and in vitro. We have established that AllerQ inhibited histamine release, cAMP/cGMP, O₂, H₂O₂ level, IL-4, tumor necrosis factor-alpha(TNF-α) and IL-6 production without having any significant physical change. These effects have been observed in mast cell(in vitro) and serum(in vivo) derived from three different origins that were activated by either immunological or non-immunological stimuli. These results suggest that the antianaphylactic and antiasthma tic action of AllerQ may be associated with an increase in the intracellular inhibition of the cAMP phosphodiesterase. Furthermore, AllerQ identified as potent inhibitors on O₂, H₂O₂ and cytokine activity. these data suggest that AllerQ may have an inhibitory role in mast cell-mediated allergic inflammation, and thus might be considered as an useful functional food.

Gangilosides are ubiquitous membrane components in mammalian cells and are suggested to play essential roles in cellular phenomena such as cell-cell interadion, differentiation, and signal transduction. Rat ovary contained GM3 as major gangiloside. Nn order to study GM3 distribution in the atretic follicles and its possible changes during follicular development, frozen sections were stained with spedfic monocional antibodies against eleven gangilo-series gangliosides including GM3. In the atretic follicles, Glf3 was expressed in a spatlo-temporally different manner during foilicular development, but GM1 and other gangliosides were not immunohistochemicaily detected. in atretic follicle from primary follicle stage, GM3 was expressed in all the theca cells and some granulosa cells adjacent to oocyte. In atretic follicle from secondary follicle stage, GM3 were expressed in all theca cells and granulosa cells. in atretic follicles from developing Graaflan follicle stages, GM3 was similarly expressed as in secondary follicle stage.

New antitumor active polymers, poly(methacryloyl-2-oxy-1,2,3-propanetricarboxylic acid-co-exo-3,6-epoxy-l,2,3,6-tetrahydrophthalic acid) [poly(MTCA-co-ETAc)], poly(methacryloyl-2-oxy-l,2,3-propanetricarboxylic acid-co-hydrogen ethyl-exo-3,6-epoxy-l,2,3,6-tetrahydrophthalate) [poly(MTCA-co-HEET)], and poly(methacryloyl-2-oxy-l,2,3-propanetricarboxylic acid-co-a-ethoxy-exo-3,6-epoxy-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil) [poly(MTCA-co-EETFU)] were synthesized and characterized. Their antitumor activity, inhibition of DNA replication and antiangiogenesis were examined. The structures of the polymers were identified by FT-IR, $^1H$ and $^{13}C$-NMR spectroscopy. The number average molecular weights of the fractionated polymers determined by GPC ranged from 9,400 to 14,900, and polydispersity indices were less than 1.7. The in vitro cytotoxicity of these polymers was determined and their antitumor activity was evaluated. The $IC_{50}$ values (the drug concentration at inhibition of 50% tumor growth) indicated that the synthesized polymers were much better inhibitors of cancer cells and showed lower cytotoxicity than the free 5-FU. The in vivo antitumor activity of the conjugates was examined using mice bearing the sarcoma 180 tumor cell line. The life spans (TIC) of the mice treated with the conjugates were higher than those treated with the free 5-FU. In addition, the synthesized conjugates showed excellent antiangiogenic activity based on an embryo chorioallantoic membrane assay.

A pesticide monitoring study was undertaken for the strawberry and cucumber samples collected from plastic film houses and additional strawberries from supermarkets located in Seoul city in 1983 to evaluate pesticide residues in these food commodities and also to give basic informations in establishing maximum residue limits. Organophosphorus insecticides were not detected in any cucumber samples except that diazinon found with low residue levels in two strawberry samples. Fungicide procymidone and chlorothalonil were detected with considerable high frequencies in these vegetables while their residue levels were fairly low. Even the maximum residue levels. they were much lower than maximum residue limits established in these vegetables in Environment Administration. Korea. Of the strawberries from supermarkets in Seoul city, procymidone, chlorthalonil and dichlofluanid fungicides were also detected with similar detection frequencies and residue levels to those from the plas tic film houses. By washing the strawberries with tap water, the residues were removed from 38% to 95% of the total residues. Presently, it is considered that pesticide residues in strawberry and cucumber may be no harmfullevels for food commodities.

The purpose of this study was to investigate the biological activities of water soluble browning reaction products(WS-BRPs) isolated from korean red ginseng. Antioxidative activities of WS-BRPs were examined with the various systems. Three different fractions prepared by os moly tic treatment of WS-BRP(fraction L, S-l and S-2) were found to have an ability to donate hydrogen to DPPH and also exhibited the inhibitory activities in lipid peroxidation, consumption of oxygen and protein oxidation of mitochondrial fraction. Especially, L had the strongest activity of these three WS­BRPs in scavenging free radicals. Lipid peroxidation showed the antioxidant effect on linoleic acid oxidation inhibition ratio of $22.5\%,\;31.7\%,\;31.9\%\;and\;33.5\%$, respectivity. And the consumption of oxygen was strongly inhibited by $49.52\%,\;62,44,\;97.54\%$. But three WS-BRPs showed weak inhibitory activity on lipid peroxidation in rat hepatic microsomes.

In recent years, Japanese style Chinese Moe-tic Ship personification games have enjoyed success in Korean game market - starting from 'Girl's Frontier' in 2017 to recent 'Azur Lane' in 2018. Their 'all female' characters have overly sexual appearance thus young male adults/adolescents are main consumers of the genre. In this paper, we investigate all 300+ character skins of the game 'Azur Lane' on how much their character illustrates have sexual exposure of the female body for the sexism and how their standard attire have different patterns with respect to the affiliated nationalities. We report that the sexual exposure is highly related to the payable skins including swim suits and there exists some sexual stereotype in characters' attire. Japanese and Chinese characters emphasize their traditional Chipao and Kimono. Japanese also wore school uniforms. German characters wore uniforms the most and many British characters wore maiden uniform. Although this game is classified as adult game, its overly sexualized female characters are harmful for young adults to cause sexual objectification of females.

Objectives: This study investigated the reliability and validity of the Korean version of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Level 2 Cross-Cutting Symptom Measure-Patient-Reported Outcomes Measurement Information System (PROMIS)-Depression and the Irritability for parents of children aged 6-17 years. Methods: Participants were 190 children diagnosed with depressive disorder (n=14), anxiety disorder (n=21), attention-deficit/hyperactivity disorder (ADHD; n=111), ADHD with anxious depression (n=13), and tic disorder with somatic symptoms (n=31). Patients were 8-15 years of age. The participants' mothers completed the Korean versions of the DSM-5 Level 2 Cross-Cutting Symptom Measure-PROMIS Depression and Irritability (Affective Reactivity Index, ARI), and the Korean Child Behavior Checklist (K-CBCL). Using these data, we calculated the reliability coefficient and examined the concurrent and discriminant validity of the PROMIS Depression and the Irritability (ARI) scales for assessing depression and irritability in children. Results: The reliability coefficient of the PROMIS Depression scale (Cronbach's α) was 0.93. The correlation coefficient with the K-CBCL DSM emotional problem score was 0.71. The PROMIS Depression scale significantly discriminated children with depressive disorders from those with other conditions. The reliability coefficient of the Irritability (ARI) scale was 0.91, suggesting its high reliability. Conclusion: Our results suggest that the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure for Depression and Irritability Scales for parents of children aged 6-17 years is reliable and valid and may be an efficient alternative to the K-CBCL.

Rapid change in the technological environment of marine transportation and the development of the ocean shipping industry have fostered a revolution in the port system. This in turn has caused major changes in the function and use of port in Korea. Aside from this, Mokpo Port, however continues to decline, because the existing port facilities and related subsystem are already obsolete with no chance of regaining operational effectiveness and treatment for proper implementation. Although a few studies have been done on the Mokpo Port, has not been found, any reseach for the analytical approach to the transportation system of it. This paper aims to make an extensive analysis of the physical distribution system in Mokpo Port focusing on the coordination of subsystems such as navigational aids system. The base of introduced simulation tool here is the queueing theory. The overall findings are as follows: 1. Among those vessels called at Mokpo Port in 1994, 556 ships(2,736,669 G/T) are oceangoing while 8155 ships(2,587,217 G/T) are domestic. The average size of oceangoing vessels is 4,922,1 G/T, and the domestic is 317,8 G/T. The average arrival interval and service time of the domestic vessels are 6.0 hours and 24.1 hours respectively marking the berth occupation rate over 100%. Those for oceangoing vessels are 34.5 hours, 120.0 hours and 37.2%. In order to maintainin the berth occupation rate to 70% the capacity considering the 1994 of domestic piers must be extended to 145% and oceangoing vessels must be increased to 165%. 2. The capacity of approaching channel is enough to handle the total traffic volume of 3. Tugs are sufficiently being provided to handle all ships requiring their services 4. The capacity of storage and inland transportation systems are sufficient to handle the throughput and the yard stroage utilization rate of No.1 - No.5 is 4.5% and No.6 is 30% of 1993's. 5. The utilization rate of LLC(Level Looping Crane) and PNT(PNeumaTic) are 2.7% and 18.8%, respectively.
