The author tried to analyse a Korean fairy tale "the traveller and the fox". The essence of the story is as follows; A traveller who was wandering in mountains found a house with a light. There was a beautiful woman who was very kind to give food and shelter. But she was a fox that tried to kill him with a knife. He asked her to bring a basket of water and he broke the wall with it to run away. The fox chased and he fell down a cliff to ride on the back of a tiger. The tiger ran into a cave and give him to her babies as a prey. He killed them by throwing stones and climbed a tree out of the cave. There came foxes and the tiger and they killed each other. He came back to the village with the fur of the foxes and the tiger. The author tried to understand the contents of the story symbolically and interpret them from the perspective of analytical psychology. On conclusion, the traveller was on the individuation process and experienced the negative anima (the fox) and the negative mother archetype (the tiger) and its negative subsidiaries (the tiger's babies). He tried to be consciously alert and paid continuous attention so that he could get out of the status and get new insight. During this process, it was meaningful that he could actively get an appropriate aid of positive mother archetype and Self symbolized by the water and the tree respectively.

Objectives: To examine effect of Korean medical treatment on child and adolescent patients with depressive disorder and correlations among changes in anxiety and anger psychological scales before and after treatment. Methods: Medical records of 28 adolescent and 9 child patients diagnosed with depressive disorder based on Diagnostic and Statistical Manual of Mental Disorders-V (DSM-V) who received Korean medical treatment (herbal-medication, acupuncture, Korean psychotherapy, and so on) for at least 8 weeks were retrospectively reviewed. Psychological scales including Beck Depression Inventory-II (BDI-II), State-Trait Anxiety Inventory (STAI), Beck Anxiety Inventory (BAI), State-Trait Anger Expression Inventory (STAXI), Children's Depression Inventory (CDI), State Anxiety Inventory for Children (SAIC), Trait Anxiety Inventory for Children (TAIC), and Children's Inventory of Anger (ChIA) were measured every four weeks and analyzed. Results: After eight weeks of treatment, STAI-X-1 (State Anxiety), STAI-X-2 (Trait Anxiety), BDI-2, BAI, STAXI-S (State Anger), AXI-K-I (Anger Expression-In) and AXI-K-O (Anger Expression-Out) showed statistically significant decreases in adolescent patients. In child patients, ChIA was significantly improved after eight weeks. For psychological scale pairs in adolescent patients, BDI-2 and STAI-X-1·STAI-X-2·BAI·STAXI-S·AXI-K-I, STAIX-T and STAXI-S·AXI-K-I showed significant positive correlations whereas AXI-K-O and AXI-K-C showed a negative correlation. In child paitents, there was a significant positive correlation for all psychological scales except for the relationship between SAIC and ChIA. In adolescent patients, low pretreatment BDI-2 predicted BAI, STAXI-S, and AXI-K-I score reduction after 8 weeks. Lower BAI scores significantly decreased STAI-X-2 and BDI-2 scores after 8 weeks but increased AXI-K-C. In child paitents, low pretreatment ChIA scores predicted a decrease in CDI score after treatment. Conclusions: Korean medical treatments including herbal medicine, acupuncture, and Korean psychotherapy were effective in improving depressive disorder and accompanying symptoms such as anxiety and anger of child and adolescent patients.

As the global climate change emergency is escalating, the need for 'Social Action-Oriented SSI (SAO-SSI) on climate change topics' in science education that can change society through social activity is increasing. By employing sociocultural theory, this study explores the challenges of limiting teacher's agency in implementing SAO-SSI on climate change topics in science education. Data from participant observation for 46 lessons, in-depth interviews with participants, field notes, and teacher reflection notes were analyzed by the structure of into micro- (classrooms), meso- (school), and macro- (Korea society) level. At the micro-level, the teacher's new attempts of SAO-SSI on climate change topics class made it difficult for him to identify students' understanding of climate change, because they have a low sense of perception that climate change is also their problem. In addition, the teacher had difficulties leading students' into an engagement for social action because students were skeptical about the feasibility of planned social behavior by positioning themselves as children or had difficulty in understanding social action and sympathizing with its values. At the meso-level, a school culture that encourages the implementation of a curriculum similar to that of colleagues, it was difficult to implement one's own curriculum. And it was difficult to develop expertise without the support and communications with colleagues who revealed the burden of unfamiliar science topics of climate change. In addition, conflicts arose in the process of implementing out-of-school social actions with the principal's passive support. At the macro-level, the insufficient proper material resources for SAO-SSI on climate change topics class, and negative perceptions on the students' social action in the society were acting as constraints. We offer implications for what kind of structural support and efforts from various subjects in the educational community should be provided to implement SAO-SSI on climate change topics class in science education.

This study analyzed the polyphenol, flavonoid contents, antioxidant activity, anti-aging activity and phenol component contents of Saccharina japonica (SJ), Costaria costata (CC) extracts with hot water, 95% methanol, 95% prethanol for investigating possible utilization of SJ and CC extracts. The result revealed that the SJ and CC methanol extracts showed the highest polyphenol and flavonoid contents, 4.63 mg TAN/g, and 4.19 mg QUE/g respectively. Also, the SJ and CC methanol extracts showed higher antioxidant activity than prethanol and hot water extracts, whereas the ABTS radical scavenging activities were the highest in prethanol extracts (IC₅₀ = 15.4, 10.3 ㎍/µL). In anti-aging activity for evaluating the anti-wrinkle activity and skin whitening activity, the CC methanol extracts had high collagenase inhibitory activity (88.3%), and the SJ prethanol extracts showed higher elastase inhibitory activity (19.0%) compared to other extracts. Then the tyrosinase inhibitory activity was significantly higher in the SJ and CC methanol extracts (41.8, 30.3%, respectively), whereas prethanol extracts were the lowest. To identify the phenol component contents of SJ and CC extracts, 4-hydroxybenzoic acid, naringenin, naringin and nicotinic acid were measured using LC-MS/MS. As a result, the phenol contents were the highest in SJ methanol extract (4-hydroxybenzoic acid), SJ and CC prethanol extract (naringin and naringenin) and CC prethanol extract (nicotinic acid). Lastly, the antioxidant activity of SJ and CC showed high correlations with polyphenol and flavonoid contents (R = -0.946~0.883). These results suggest that prethanol or methanol extracts of SJ and CC have higher antioxidant activities, anti-aging activity and the potential to be used as material for health functional food and cosmetics.

Among the subgroups of speech sound disorder (SSD), the motor speech disorder (MSD) group is characterized by weak articulatory force. This study quantitatively measured and compared articulatory muscle strength between SSD and typically developing (TD) children. The Iowa Oral Performance Instrument (IOPI) was used to measure lip and tongue strength in 15 children with SSD and 15 TD children. We additionally measured peak lip and tongue pressure and endurance, and analyzed the correlation between each strength measure and the percentage of consonants correct (PCC). The findings were as follows: First, lip strength for the bilabial sounds did not differ between the two groups in the initial position but was significantly weaker in the SSD group in the final position. Tongue strength for alveolar sounds was weaker in the SSD group than in the TD group for the initial and final positions. Second, for lip and tongue strength, the difference in voicing features was significant in the TD group but not in the SSD group. Third, the peak pressure and endurance of the lips and tongue were significantly lower in the SSD group than in the TD group. Fourth, significantly higher static correlations were observed between most strength measures and the PCC. These findings suggest that weakness in articulatory motor execution may be an unrecognized underlying problem of SSD with unknown origin.

The purpose of this study was to examine parental perceptions on the importance, performance level, and satisfaction with foodservice quality at daycare centers in the Compensation and Welfare Service institute. The questionnaire was developed to measure thirty-two attributes of foodservice operations are administered to 598 parents and 23 foodservice supervisors from June 22, 2009 to July 10, 2009. The parents placed a high importance on the need for foodservices, earning 4.70 points out of 5 points. Their perceptions of foodservice quality menu, foodservice ingredients and effects, facilities, sanitation, and service scored even higher than performance. The overall satisfaction level for foodservice compared to performance was 4.33 and 4.03 points out of 5 points, respectively. Multiple regression analysis indicated that 98.6% of the variance in parents' overall satisfaction scores was explained by six dimensions.

The use of phonosurgery in the recent development of laryngomicrosurgery has enabled the restoration of a normal voice in respect to functional laryngeal surgery which in Korea in the past limited to simple removal of benign laryngeal tumor such as laryngeal polyp or nodules and cordal injection of $Teflon^{{\circledR}}$ for the treatment of recurrent nerve paralysis under the vision of suspension laryngoscopy. Performance of phonosurgery for the treatment of cord paralysis, mutational dysphonia, vocal cord atrophy, hyperkinetic dysphonia and sulcus vocalis is a happy event in the view point of development of phonosurgery in Korea. In this aspect thyroplasty to change the position and physical characteristics of the cord outside the glottis instead of the direct handling of the vocal cord through direct endoscopy is popular. Among the 4 types of thyroplasty, classified by Insshiki(1974), type I thyroplasty(1ateral compression of vocal cord) and type IV thyroplasty(lengthening of vocal cord) were effective in the treatment of unilateral vocal cord paralysis. Advantages of this operation are the fine adjustment of the degree of lateral compression under local anesthesia according to the phonation of the patient during operation and avoidance of dyspnea and intralaryngeal hemorrhage due to the manipulation outside the internal perichondrium of the thyroid cartilage. We did 7 cases of thyroplasty for the treatment of unilateral vocal cord paralysis in the 7 months from September 1981 to March 1982. Before the operation aerodynamic study, psychoacoustical evaluation, stroboscopy and sound spectrographic analysis were done. Two months after the operation the above procedures were performed again. Results of preoperative and postoperative examination were compared and the following results were obtained. 1) In the aerodynamic study, maximum phonation time increased to 158% of the preoperative value and the phonation quotient and the mean flow rate decreased to 58% and 54% of preoperative values. 2) The degree of hoarseness improved in the psychoacoustical evaluation and the glottic chink during phonation was decreased in the stroboscopic examiantion. 3) In the sound spectrographic analysis, periodicity was much restored and noise distribution decreased especially in the high frequency area.

Thymosin β-4 (TB4) is a small peptide composed of 43 amino acids. To obtain sufficient biologically active mouse TB4 economically, we cloned and overexpressed this gene in an Escherichia coli system. With the isopropyl β-D-1-thiogalactopyranoside induction of the E. coli transformant, TB4 fusion protein with intein- and chitin-binding domain was successfully expressed in the soluble fraction within the E. coli cell. The TB4-intein - chitin-binding domain fusion protein was purified from the soluble fraction of E. coli cell lysate. The affinity chromatography with chitin beads and dithiothreitol-mediated intein self-cleavage reaction releases the TB4 peptide into the stripping solution. Sodium dodecyl sulphate - polyacrylamide gel electrophoresis and Western blot analyses were used to confirm that the recombinant TB4 peptide was produced with the expected size of 5 kDa. We found that the recombinant TB4 stimulated cell migration in the transwell plate chamber assay. After 18 hr of the treatment of the recombinant TB4 with 1 ng/ml concentration, the migration of the HT1080 cell was increased by 20% compared with that of the chemically synthesized TB4. The recombinant TB4 was also observed to promote the healing of a wound area in C57BL/6 mice by as high as 35% compared with that of the chemically synthesized TB4. These results suggest that the recombinant TB4 has better biological activity for cell migration and wound healing than that of the chemically synthesized TB4 peptide.

Oxidative stress plays a significant role in the pathogenesis of various skin conditions, resulting in cellular and tissue damage that can contribute to the development of skin tone unevenness, roughness and wrinkles. In this study, we found that Trifolium pratense L. extract (TE) attenuated oxidative-induced damage in HaCaT cells and elucidated the underlying molecular mechanism. Our finding demonstrated that TE effectively protected HaCaT cells against H₂O₂-induced cell death by inhibiting caspase-3 activation, downregulating Bax and upregulating Bcl-2, and attenuating the activation of three mitogen-activated protein kinases (MAPKs). Our results suggest that TE has remarkable cytoprotective properties against oxidative damage in HaCaT cells and could serve as a complementary or alternative approach to prevent and treat skin damage.

Non-specific chronic neck pain (CNP) is a prevalent disorder and often accompany with pain, fatigue, reduced range of motion (ROM), and hand function. Although various types of drug are commonly used to manage the symptoms following CNP, there is a need for therapeutic exercise and alternative medicine interventions that have few side effects or are easy to apply. Present study investigated the effects of salt pack and neck exercise for life care of the elderly with non-specific CNP. Sixteen patients with non-specific CNP were recruited and randomly assigned into two groups: the intervention group (n=8) or the control group (n=8). All patients performed neck self-exercise for 30 min/day, 5 times a week for 1 week. And the subjects in the intervention group additionally received salt hot pack for 20 min per session. Visual analogue scale (VAS) and pain pressure threshold (PPT) using algometer were used to assess pain intensity (primary outcome). ROM of shoulder joint and grip strength were measured to test shoulder and hand function (secondary outcome). There were significant improvements in the intervention group (p<.05), while the subjects in the control group did not show a significant change after intervention (p>.05). Also, the intervention group show significant differences in VAS and PPT compared to the control group (p<.05). Thus, our results demonstrated that salt pack and neck exercise have a positive effect for life care in elderly patients with non-specific CNP.
