This study was performed to investigate purchasing practice and size satisfaction in order to offer basic data to establish marketing strategy and produce ready-made clothes for the male college students according to their body type. For data analysis, crosstabs, factor analysis and one-way ANOVA were used. Results were as follows; first, this study considered the somatotype distribution of male college students. The results showed that inverted triangle -shaped torso was the ideal somatotype in all the classified four actual somatotypes. Second, people in standard body types significantly considered price and appearance such as design, color, pattern and price while people in triangle-shaped torso placed the most importance in the practicality and wearability. People with inverted triangle-shaped torso was found to significantly consider the perceptual quality such as brand, a/s and fashion. Third, this study considered the wearing satisfaction of ready-to-wear. The respondents placed more emphasis on the practicality and wearability as their actual somatotypes were not ideal for them. Fourth, the examination of the difference in size fitness depending on clothing by somatotype when wearing ready-to-wear showed that breast on the top was small when wearing it in the remaining somatotypes except for standard somatotype. The upper body showed better size fitness in triangle-shaped torso. There is a difference in fitness according to somatotypes classified by the form factors even though they have the same body mass index.

The Danish-Icelandic artist, Olafur Eliasson who was born in 1967 is known for installation projects employing materials such as colour, fog, mirror and light to rethink the relationship between human and surrounding. Since he started the early projects, Eliasson has been interested in the relationship between an art, a viewer and space. He has used the medium from nature because he thought nature is very common subject to derive new idea of relationship between human and surrounding. Eliasson revealed the idea of relationship between human and surrounding by three characteristics of spatial design such as 'reinterpretation of placeness by juxtaposition of mediums and defamilarization', 'ambiguity and extensity of depth distance of space by mediums' and 'change in spatiality by movement of viewers and time'. This paper focused on four case projects : The mediated motion in 2001, The weather project in 2003, The blind pavilion in 2003, Your rainbow panorama in 2011. It is aimed to discover relationship between human and surrounding in the case projects under three characteristics. This study found that three characteristics were differently applied in the case projects in terms of spatial experience and design methods. Inside & outside locations, formal quality, visual-perceptual relationships in and around each case are crucial elements and tools. The unique relationship between human and surrounding of Eliasson and three characteristics are applicable to architecture and spatial design.

Pain is a complex perceptual experience that is profoundly influenced by a number of variables, differing in quality as well as in intensity. Therefore we need to understand the actual experience of multiparous women in order to provide basic information for nursing care. The purpose of the study is to explore the experience of labor pain. The data are collected through in-depth interviews of 17 multiparous women in city of Pusan from October 1998 to March 1999. The interviews were conducted 1-2 days after delivery in the admission room. Each interview lasted about 45 minutes on average. Subjects were interviewed one at a time. The interviews were recorded with the consent of the subject. Data were analyzed by means of Giorgi's Phenomenological analysis methods and categorized according to the similarities of its contents. The investigator read the data repeatedly to identify themes and categories. Six categories that were identified were : 1) pain 2) regret 3) acceptance 4) maturity 5) accomplishment 6) newness. Under these categories there were seventeen themes. I. Pain: 1) too dependent on others 2) too painful 3) fear or anxiety from previous painful experience 4) avoidance of pain 5) couldn't control the pain II. Regret : 1) spouse's absence 2) unprofessional attitude of the staff 3) ignorance of other's towards their pain III. Acceptance : 1) took the pain for granted 2) accepted the pain as fate 3) endured the pain IV. Maturity : 1) appreciated the value of life 2) apprehension of parent V. Accomplishment : 1)is over sense of accomplishment 2) grateful the pain VI. Newness : 1) experienced a new feeling 2) quickly forgot the pain.

Background and Objectives : This study aimed to determine the clinical effect of $Artecoll^{(R)}$ injection laryngoplasty for patients with vocal atrophy and mild sulcus vocalis. Materials and Method : Forty-one patients with vocal atrophy and/or mild sulcus vocalis received transcutaneous $Artecoll^{(R)}$ injection into the vocal folds under local anesthesia. Subjective evaluations including voice handicap index (VHI) and perceptual grading with Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scales and objective evaluations including jitter, shimmer, noise-to-harmonic ratio (NHR), speaking fundamental frequency (SFF) and maximum phonation time (MPT) were evaluated before and 3 months after the injection. Results : VHI and Grade, Breathiness and Strain scales in GRBAS showed significant improvement 3 months after injection. SFF and MPT also significantly improved after the injection ; MPT increased and SFF in male patients decreased. Conclusion : Injection laryngoplasty with $Artecoll^{(R)}$ is an effective method for correcting the glottal insufficiency and improving voice quality in patients with vocal atrophy and/or mild sulcus.

To enhance the speech perception of hearing aid users in noisy environment, most hearing aid devices adopt various beamforming algorithms such as the first-order differential microphone (DM1) and the two-stage directional microphone (DM2) algorithms that maintain sounds from the direction of the interlocutor and reduce the ambient sounds from the other directions. However, these conventional algorithms represent poor directionality ability in low frequency area. Therefore, to enhance the speech perception of hearing aid uses in low frequency range, our group had suggested a fractional delay subtraction and integration (FDSI) algorithm and estimated its theoretical performance using computer simulation in previous article. In this study, we performed a KEMAR test in non-reverberant room that compares the performance of DM1, DM2, broadband beamforming (BBF), and proposed FDSI algorithms using several objective indices such as a signal-to-noise ratio (SNR) improvement, a segmental SNR (seg-SNR) improvement, a perceptual evaluation of speech quality (PESQ), and an Itakura-Saito measure (IS). Experimental results showed that the performance of the FDSI algorithm was -3.26-7.16 dB in SNR improvement, -1.94-5.41 dB in segSNR improvement, 1.49-2.79 in PESQ, and 0.79-3.59 in IS, which demonstrated that the FDSI algorithm showed the highest improvement of SNR and segSNR, and the lowest IS. We believe that the proposed FDSI algorithm has a potential as a beamformer for digital hearing aid devices.

Vocal process granuloma can occur commonly by laryngopharyngeal reflux (LPR), vocal abuse or misuse. It has been reported that voice therapy is employed with medication therapy for the patients who has vocal process granuloma, however research about effect of voice therapy can be hardly founded. For that matter, the primary aim of this study was to evaluate the effect of therapeutic method we implement. Thirty one patients who has been diagnosed with vocal process granuloma from January, 2007 to June, 2009 participated in this study. 19 patients among them are provided voice therapy and medication, 12 patients take only medication. Voice therapy is implemented ranging from 5 to 19 sessions (mean: 8.6 sessions). We provided explanation about problem each patient has, voice rest, SKMVTT$^{(R)}$, abdominal breathing, and relaxation in session. All subjects were examined by videostroboscopy, perceptual assessment, acoustic and aerodynamic measures. Consequantly, the greater part of the patients (78.9%) who is treated by voice therapy and medication are confirmed disappearance or decrease of granuloma, it shows better results compared with the group provided only medication (66.7%). Especially, the period of drug administration is 3.7 months in the group runs parallel with voice therapy, the period of other group is 7.8 months. The results of acoustic and aerodynamic measures after treating indicates there are significant decrease in Jitter, Shimmer, and NHR, and increase in MPT, Psub (p<.05). However, there is no large difference statistically even though voice quality has improved since the therapy. In conclusion, it is verified that the voice therapy to the vocal process granuloma patients taking medication is effectual method, we recommend combining voice therapy with medication when treatment is needed for the vocal process granuloma patients.
