Purpose: This was a pilot study to examine the clinical usefulness of the newly developed three-dimensional sweep mode extracorporeal shockwave treatment (ESWT) in patients with plantar fasciitis. Materials and Methods: Three-dimensional sweep mode ESWT was performed once a week for 5 weeks in patients with plantar fasciitis who showed no improvement with the conventional conservative treatment. A 100-mm visual analogue scale (VAS) reading for pain from walking and at rest after walking were collected before the treatment and 8 and 16 weeks after the initial treatment. In addition, the Foot and Ankle Outcome Score (FAOS) and EuroQol-5-dimension (EQ-5D) scores before and 16 weeks after the treatment were evaluated. Results: VAS for pain for walking improved from 50.60±8.38 to 19.80±15.61 at 8 weeks after the initial treatment (p=0.008) and 9.80±9.62 at 16 weeks after the treatment (p<0.001). VAS for pain at rest after walking improved from 36.60±19.55 to 11.80±12.95 at 8 weeks after the initial treatment (p=0.052) and 8.80±8.87 at 16 weeks after the treatment (p=0.024). Preoperative FAOS increased from an average of 74.80±9.73 before the treatment to an average of 81.00±8.86 at week 16 after the procedure (p=0.49) and compared to pre-treatment levels, there was a decrease of one level in the anxiety/depression domain of the EQ-5D, post-treatment. Conclusion: The results of this preliminary study confirmed that the newly developed EWST with the smart forging sweep mode was effective in improving pain and function in plantar fasciitis.

The aim of this study Is to develop a simple and fast method which computes in-vivo doses from transmission doses measured doting patient treatment using an ionization chamber. Energy fluence and the dose that reach the chamber positioned behind the patient is modified by three factors: patient attenuation, inverse square attenuation. and scattering. We adopted a straightforward empirical approach using a phantom transmission factor (PTF) which accounts for the contribution from all three factors. It was done as follows. First of all, the phantom transmission factor was measured as a simple ratio of the chamber reading measured with and without a homogeneous phantom in the radiation beam according to various field sizes($r_p$), phantom to chamber distance($d_g$) and phantom thickness($T_p$). Secondly, we used the concept of effective field to the cases with inhomogeneous phantom (patients) and irregular fields. The effective field size is calculated by finding the field size that produces the same value of PTF to that for the irregular field and/or inhomogeneous phantom. The hypothesis is that the presence of inhomogeneity and irregular field can be accommodated to a certain extent by altering the field size. Thirdly, the center dose at the prescription depth can be computed using the new TMR($r_{p,eff}$) and Sp($r_{p,eff}$) from the effective field size. After that, when TMR(d, $r_{p,eff}$) and SP($r_{p,eff}$) are acquired. the tumor dose is as follows. $$D_{center}=D_t/PTF(d_g,\;T_p){\times}(\frac{SCD}{SAD})^2{\times}BSF(r_o){\times}S_p(r_{p,eff}){\times}TMR(d,\;r_{p,eff})$$ To make certain the accuracy of this method, we checked the accuracy for the following four cases; in cases of regular or irregular field size, inhomogeneous material included, any errors made and clinical situation. The errors were within 2.3% for regular field size, 3.0% irregular field size, 2.4% when inhomogeneous material was included in the phantom, 3.8% for 6 MV when the error was made purposely, 4.7% for 10 MV and 1.8% for the measurement of a patient in clinic. It is considered that this methode can make the quality control for dose at the time of radiation therapy because it is non-invasive that makes possible to measure the doses whenever a patient is given a therapy as well as eliminates the problem for entrance or exit dose measurement.

This thesis was a phenomenological study of an after-school picture book making program for middle school students. This study attempted to establish a theoretical system for picture book making activity by analyzing the process of self-discovery and healing through the picture book making activity. The participants were six middle school students, the picture book making activity program was organized into five stages, and in-depth interviews of the study participants and their interpretation of picture books were described. According to the research results, first, the making activity of picturebooks can construct one's own world through hyper-reality that is more excessive than the original. Second, it can be said that the fearful existence of a monster has developed awareness and insight to view its own problems from various angles through defamiliarization. These results might be that the making activity of picturebooks is a way of revealing one's existence to the world, and through this, the process of exploring and constructing the meaning of oneself and daily life. Discussion was made based on this about the creation of another world where the picturebook making activity is different from the original, the stimulating effect of the subconscious mind through the defamiliarization device, and the establishment of self-existence in picturebook creation.

Purpose : With the development of stereotactic immobilization systems capable of reliable serial repositioning, fractionated stereotactic radiation therapy (FSRT) offers the Potential for an improved treatment outcome by excellent dose delivery, and dose distribution characteristics with the favorable radiobiological properties of fractionated irradiation. We describe our initial experience using FSRT for the treatment of intracranial benign tumor. Materials and Methods : Between August 1995 and December 1996. 15 patients(7 males and 8 females aged 6-70 years) were treated with FSRT. The patients had the following diagnosis pituitary adenoma(10) including one patient who previously had received radiotherapy, craniopharyngioma (2), acoustic neurinoma (1), meningioma (2). Using the Gill-Thomas-Cosman relocatable head frame and multiple non-coplanar therapy, the daily dose of 2Gy was irradiated at 90% to 100% isodose surface of the isocenter The collimator sizes ranged from 26mm to 70mm. Results : In all patients except one follow-up lost, disease was well-controlled. Acute complication was negligible and no patient experienced cranial nerve neuropathies and radiation necrosis. In overall patient setup with scalp measurements, reproducibility was found to have mean of $1.1{\pm}0.6mm$ from the baseline reading. Conclusion : Relocatable stereotactic system for FSRT is highly reproducible and comfortable. Although the follow-up period was relatively short. FSRT is considered to be a safe and effective radiation technique as the treatment of intracranial tumor. But the fractionation schedule(fraction size, overall treatment time and total dose) still remains to be solved by further clinical trials.

Recently, the uses of Multi-Detector Computed Tomography (MDCT) for radiation treatment simulation and planning which is used for intensity modulated radiation therapy with high technique are increasing. Because of the increasing uses of MDCT, additional doses are also increasing. The objective of this study is to evaluate the absorbed dose of body and skin undergoing in MDCT scans. In this study, the exposed dose at the surface and the center of the cylindrical water phantom was measured using an pencil ionization chamber, 30 cc ionization chamber and TL Powder. The results of MDCT were 31.84 mGy, 33.58 mGy and 32.73 mGy respectively. The absorbed dose at the surface showed that the TL reading value was 33.92 mGy from MDCT. These results showed that the surface dose was about 3.5% from the MDCT exposure higher than a dose which is located at the center of the phantom. These results mean that the total exposed dose undergoing MDCT 4 times (diagnostic, radiation therapy planning, follow-up et al.), is about 14 cGy, and have to be considered significantly to reduce the exposed dose from CT scan.

Purpose : By sequencing the Erpressed Sequence Tags of human 걸ermal papilla CDNA library, we identified a clone named K872 of which the expression decreased during differentiation of HL6O cell line. Materials and Methods : K872 plasmid DNA was isolated according to QIA plasmid extraction kit (Qiagen GmbH, Germany). The nucleotide sequencing was performed by Sanger's method with K872 plasmid DNA. The most updated GenBank EMBL necleic acid banks were searched through the internet by using BLAST (Basic Local Alignment Search Tools) program. Nothern bots were performed using RNA isolated from various human tissues and cancer cell lines. The gene expression of the fusion protein was achieved by His-Patch Thiofusicn expression system and the protein product was identified on SDS-PAGE. Results : K872 clone is 1006 nucleotides long, and has a coding region of 675 nucleotides and a 3' non-coding region of 280 nucleotides. The presumed open reading frame starting at the 5' terminus of K872 encodes 226 amino acids, including the initiation methionine residue. The amino acid sequence deduced from the open reading frame of K872 shares $70\%$, identity with that of rat glutathione 5-transferase kappa 1 (rGSTKl). The transcripts were expressed in a variety of human tissues and cancer cells. The levels of transcript were relatively high in those tissues such as heart, skeletal muscle, and peripheral blood leukocyte. It is noteworthy that K872 was found to be abundantly expressed in coloreetal cancer and melanoma cell lines. Conclusion : Homology search result suggests that K872 clone is the human homolog of the rGSTK1 which is known to be involved in the resistance of cytotoxic therapy. We propose that meticulous functional analysis should be followed to confirm that.

Background and Objectives : Vowels and resonant including nasals and liquid are produced with vocal folds vibration have been used for voice therapy of hyperadduction patients. This study was conducted to investigate phonatory characteristics of vowels and resonant consonants through the EGG measures from Lx. Speech studio (Laryngograph Ltd, UK). Materials and Method : 7 male adults produced sustained vowel /a/, /i/, /u/, nasals /m/, /n/, /${\eta}$/and liquid /I/ and read the sentences (1nasals-liquid sentence, 1 non-nasals-liquid sentence) and tongue-tip trill and humming. Fx(Hz), Ox(%) were obtained of vowels, nasals, liquid and each of the posterior vowel /a/ of /ma/, /na/, /la/, /ha/ with same F0(around F#165Hz) and amplitude (75${\pm}$5db). And also DFx(Hz), DQx(%), CFx(%) and CAx(%) were obtained from reading two kinds of sentences. Results : Qx(%) was the highest in /u/ of vowels, and nasal/n/ of the resonant consonants and nasals-liquid sentence was higher Qx than non-nasals-liquid sentence but significant differences were not found. Qx(%) of the posterior vowel /a/ of nasal consonants/n/ was higher than in the isolated vowel/a/ and other posterior vowel of resonant consonants and fricatives /h/. Regularity or periodicity and higher Qx were observed in the nasals-liquid sentence than non-nasals-liquid sentence in graphs of QxFx & CFx produced by Quantiative analysis. In the nasalance score, /u/vowel was significant higher among the vowels and /I/ liquid was significant lower among the resonant consonants and nasals-liquid sentence is higher than non-nasals -liquid sentence. CQ(%) was not significantly correlated with nasalance(%). Conclusion : These findings might signify resonant phonation was not correlated with nasalance.

This is an exploratory study based on the literature reviews which examined the possibilities and necessities of multimodal writing curriculum for liberal education. The purpose of this study is to analyze the existing research results which utilized the teaching methods associating music and writing, and to find the educational implications, and finally in terms of writing education, to suggest the possibilities of writing classes' convergent forms with music extracted from the results of the existing studies. Those studies were categorized to four patterns: WAC, effects of therapy, materials for writing, and new literacy. Based on Meyrowitz's perspective, firstly music can be utilized as a circumstance, which means a teacher can indirectly take the emotional, reminding, and healing effects of background musics. Secondly, music can play an important role of materials in thinking and writing, which is the most generally utilized pattern today. The effects are found in all of affective, cognitive, and strategic domains by utilizing music as a sort of reading materials. Thirdly, the convergent writing of music and narrative is suggested. Music is an independent language that can interact with narrative and construct text meanings in this kind of writing classes. These three dimensions of convergence have different perspectives, but sometimes occur at a same time or as a connected pattern. This study proposes that writing teachers need to improve their competence in music as well and to have professional concerns and efforts to develop their convergent writing teaching skills with music for these classes. Finally, this study stresses that team teaching can be an alternative for them.

This study analyzes the spectrum of recommended books for adults included in the bibliotherapy book lists commonly used in libraries and organizations in the UK, US, and Korea. While the recommended book lists in the UK and US retain a diverse range of books relevant to the practitioners' needs, the Korean bibliotherapy book lists are mostly made up of non-fiction self-help books regardless of where the bibliotherapy service is provided. In the subcategory of the bibliotherapy book lists in the UK and US, aside from fictions, books on "health, fitness, dieting" including medical books rank higher than any other kind, which shows that bibliotherapy claims to have therapeutic effects in those organizations. In Korean bibliotherapy book lists, on the other hand, so-called "psychology books impregnated with self-help ideology" take up more than 60%. With the prospect of bibliotherapy as an interdisciplinary practice in mind, I suggest that bibliotherapy should draw upon the insights from humanities in order to help participants have time for deep introspection and attain inner maturity rather than just try to restore their normal conditions before the crisis.

The purpose of this study was to compare the vocal characteristics of 40 adults with and without cerebral palsy (CP), upon presentation of three speech tasks (i.e., reading, chanting, and singing). The Praat program was utilized to generate data on fundamental frequency, voice intensity, jitter, and shimmer. The results of the analysis revealed no significant differences on fundamental frequency and intensity. However, both groups showed significant decreases in jitter and shimmer when engaged in singing tasks. The analysis of group differences indicated that adults with CP showed significantly higher variation scores on jitter and shimmer than the group without CP, and the difference on jitter and shimmer became greater during rhythmic chanting. In terms of jitter variation, the interaction effects according to the groups and types of speech tasks were greater, demonstrating the differences between the two groups. This study can be utilized as a basic research, regarding changes in vocal characteristics of adults with CP according to different musical speech tasks.
